Best Invoicing Software for Virtual Assistants: 11 Tools Ranked for 2026

Finding the best invoicing software for virtual assistants comes down to one question: can it handle eight clients with three billing models in the same week? Client A pays a $2,000/month retainer for 20 hours of executive support. Client B pays $35/hour for ad-hoc social media scheduling, tracked in 15-minute increments. Client C hired you for a one-time $800 website migration project. Each needs a different invoice structure, a different payment schedule, and a different set of line items. Miss one invoice cycle across eight accounts and you lose $400-$2,000 in delayed cash while chasing payment through email threads that multiply faster than the billable work itself.

Most VAs start with a spreadsheet and Stripe payment links. It works for two clients. By client five, the manual process breaks: you forget to invoice Client B for the extra 3.5 hours last Thursday, you send Client A the wrong retainer amount because you adjusted the scope two months ago and forgot to update the template, and Client C's project fee sits unpaid for 18 days because neither of you remembers who was supposed to initiate the payment. Add international clients across time zones and the problem compounds with currency conversions, varying payment rails, and due dates that land at 3 AM your time.

This guide ranks 11 invoicing platforms against what virtual assistants actually need: time tracking that converts directly to invoice line items, multi-client billing without cross-contamination, retainer and hourly billing in the same account, international payment support, and pricing that does not eat the margins on a $25/hour engagement. Every price was verified against the vendor's official pricing page on April 16, 2026.

Quick Comparison: VA Invoicing Platforms at a Glance

What to Look for in VA Invoicing Software

Virtual assistants bill differently from agencies, coaches, or traditional freelancers. The invoicing tool has to handle multiple concurrent clients with different billing models running simultaneously in the same account.

Time tracking that feeds directly into invoices. The single highest-value feature for an hourly VA is a timer that runs while you work on Client B's Instagram scheduling, tags those 47 minutes to Client B's project, and converts those tracked minutes into an invoice line item without you re-entering a single number. Tools that do this natively (Agiled, FreshBooks, Harvest, Paymo, Bonsai) eliminate the 15-20 minutes per client per week that VAs spend on manual invoice assembly. Multiply that across 8 clients and you recover 2+ hours of billable time every week.

Multi-client isolation without cross-contamination. When you bill 8 clients from one account, the invoice for Client A must never accidentally include hours logged to Client B. The tool needs clean project-level separation, per-client dashboards or portals, and reporting that filters by client without manual effort. A VA who sends a client an invoice containing another client's project name loses trust instantly.

Retainer, hourly, and project billing in the same account. Most VAs do not bill one way. They run a $2,000/month retainer for one client, hourly at $35/hr for another, and a flat $800 project fee for a third. The invoicing tool must support recurring invoices, time-based invoices, and flat-rate invoices without forcing you into separate accounts or workflows for each.

International payment support. A significant portion of VAs serve clients in different countries. A US-based VA billing a client in the UK needs GBP invoicing, and a Philippines-based VA billing US clients needs USD invoicing with a payout rail that actually works (Wise, PayPal, or Payoneer). Multi-currency invoicing with automatic exchange rates saves the manual conversion math that introduces errors on every cross-border invoice.

Low per-invoice economics at VA rates. Payment processing fees (2.9% + $0.30 per transaction) hit harder at VA billing volumes than at agency rates. On a $25/hr VA billing 20 hours ($500 invoice), the processing fee is $14.80 per month or $177.60/year per client. On a $2,000 retainer, it is $58.30/mo or $699.60/year. Add a $23-$49/month software subscription and the tool cost can eat 3-5% of a solo VA's revenue. Free tools (Wave, Zoho Invoice, Agiled free tier) matter more at VA margins than at any other service profession.

1. Agiled: Best All-in-One Invoicing for Virtual Assistants

Agiled is the only platform on this list that combines invoicing, CRM, time tracking, project management, contracts with e-signatures, client portals, and scheduling in a single subscription. For a VA currently paying for Toggl Track + Stripe payment links + a separate CRM + Google Docs for contracts, Agiled collapses the entire tool stack into one login.

Why it works for virtual assistants:

A VA's billing cycle has a predictable shape: track time on a client project, generate an invoice from the tracked hours or the retainer schedule, send it through a client portal, collect payment via Stripe or PayPal, and log the revenue for tax reporting. Agiled's invoicing feature handles every step natively without switching between apps.

When you start a timer on Client B's social media project, those minutes flow into Agiled's time tracking module. At the end of the week, you convert the tracked time into an invoice with one click. The line items populate automatically with the hours, the agreed rate, and the project name. For Client A on a $2,000 monthly retainer, you set up a recurring invoice that fires on the 1st of every month with autopay enabled. For Client C's one-time project, you create a milestone-based invoice that releases payment when the website migration is complete. All three billing models live in the same dashboard, separated by client workspace.

Core invoicing capabilities for VAs:

• Time tracking to invoice -- Start/stop timers per project, tag by client, convert tracked hours to invoice line items in one click
• Recurring invoices -- Monthly retainers, weekly billing cycles, biweekly schedules, or custom intervals with autopay via Stripe
• Multi-currency -- Bill US clients in USD, UK clients in GBP, EU clients in EUR with automatic FX conversion at current rates
• Payment options -- Stripe for cards, PayPal, ACH/bank transfer, Wise for international payouts
• Client portal -- Each client gets a branded login to view invoices, download receipts, check project status, and access shared documents
• Contracts with e-signatures -- Send a VA service agreement and trigger the first invoice from the same record (Premium plan)
• Estimates and proposals -- Send a scope-of-work proposal with hourly rate tiers and convert the accepted option directly into a recurring invoice
• Late fee automation -- Auto-apply a percentage or flat-dollar late fee after a configurable number of days past due
• Project-level reporting -- See revenue, hours logged, and outstanding invoices per client without spreadsheet exports

Cost analysis for a solo VA with 8 clients:

Agiled's free plan covers 2 billable clients, 100 contacts, and basic invoicing. Pro at $25/month billed annually ($300/year) unlocks unlimited contacts, unlimited invoices, deal pipelines, and time tracking for up to 3 users. Premium at $49/month billed annually ($588/year) adds workflow automations, proposals, contracts with e-signatures, and expanded client portals for up to 7 users.

Compare to a typical VA stack: Toggl Track Starter for time tracking ($9/mo), FreshBooks Lite for invoicing ($23/mo), a separate CRM like HubSpot free (limited), and DocuSign Essentials for contracts ($15/mo). That is $47/month or $564/year in separate tools versus $300/year with Agiled Pro. A VA running 8 clients at an average of $1,200/month combined revenue saves the cost of 5+ billable hours per year in tool spend alone -- and gains integrated time tracking, CRM, and client portals that the stacked tools do not offer.

Best for: Solo VAs and small VA teams who want time tracking, invoicing, CRM, and client portals without paying four separate subscriptions. VAs billing internationally who need multi-currency without upgrading to a paid tier on other platforms. Any VA managing 5+ active clients where manual invoicing is no longer viable.

Tradeoff: Agiled's feature breadth means there is a one-to-two-week setup period while you configure client workspaces, invoice templates, and time tracking categories. VAs who only need a single function (track time, create invoice, collect payment) will find Harvest or Wave faster to set up on day one, but they will also miss the CRM, contracts, and client portals that make Agiled worth more than the sum of its parts once you scale past 5 clients.

2. FreshBooks: Best for Hourly VAs Who Bill by Tracked Time

FreshBooks is the most widely recommended invoicing tool on r/freelance for service providers who bill by the hour. For VAs running hourly engagements across multiple clients, FreshBooks pairs its built-in time tracker directly with the invoice generator so tracked hours become invoice line items without manual data entry.

Key features:

• Time tracker with project and client tagging, one-click conversion to invoice line items
• Recurring invoices with autopay via Stripe or ACH
• Expense capture with receipt OCR for Schedule C-ready categorization
• Automated payment reminders and configurable late fees
• Client-facing portal for invoice viewing and payment

Pricing: Lite at $23/month for up to 5 billable clients, Plus at $43/month for up to 50 billable clients, Premium at $70/month for unlimited clients. 30-day free trial. Payment processing at 2.9% + $0.30 for cards, 1% for ACH (capped at $10). Additional users at $11/month each.

Best for: Hourly VAs who need the tightest possible loop between "time tracked" and "invoice sent." VAs who also need proper double-entry bookkeeping alongside invoicing for tax season.

Tradeoff: The 5-client cap on the Lite plan is too tight for most working VAs, which forces the jump to Plus at $43/month within the first quarter of scaling. That is a significant expense on a $25-$35/hr VA's margins. No native contracts or CRM without add-ons, and no client portal beyond invoice viewing.

3. Wave: Best Free Invoicing for VAs Starting Out

Wave is the only genuinely free, full-featured invoicing and accounting tool on this list. For a VA in their first six months with 1-4 paid clients and less than $3,000/month in revenue, Wave covers invoicing, bookkeeping, and basic reporting at $0/month with no client cap.

Key features:

• Unlimited invoices and unlimited clients on the free Starter plan
• Recurring invoices with autopay (via Wave Payments)
• Double-entry accounting with categorized expenses
• Bank feed connections for automatic transaction import
• Receipt scanning on the Pro plan ($19/mo) or as standalone add-on ($8/mo)

Pricing: Starter plan is free forever (core invoicing and accounting). Pro plan is $19/month (adds automated receipt scanning, multi-user access, discounted processing on first 10 transactions/month). Payment processing at 2.9% + $0.60 for cards (higher per-transaction than Stripe standard), 1% ACH.

Best for: New VAs in their first year with 1-4 clients, VAs who need clean bookkeeping for tax season without a subscription, and budget-conscious VAs who prioritize $0/month over feature depth.

Tradeoff: No built-in time tracking. A VA billing hourly must track time separately (Toggl free tier, Clockify, or a spreadsheet) and manually enter the hours into Wave invoices. That manual transfer is where invoicing errors happen. The $0.60 per-transaction fee (versus Stripe's standard $0.30) adds up: on 8 monthly invoices of $500 each across a year, Wave costs $28.80 more in per-transaction fees than tools that use standard Stripe pricing. No contracts, no client portal, no CRM.

4. Harvest: Best Time-to-Invoice Pipeline for Multi-Project VAs

Harvest has been the default time tracking tool for freelancers and consultants since 2006. For VAs who track time across 5-10 client projects in the same week, Harvest's time-to-invoice pipeline is the fastest on this list: start a timer, tag the project, stop the timer, and generate an invoice from the tracked entries at the end of the billing cycle.

Key features:

• Start/stop timers and manual time entries with project, client, and task tagging
• One-click invoice generation from tracked time entries with automatic line-item population
• Per-project and per-client budget tracking with alerts when approaching limits
• Expense tracking with receipt capture
• Integrations with Asana, Trello, Slack, QuickBooks, and Xero for VA workflow compatibility

Pricing: Free plan for 1 seat and 2 projects. Teams plan at $11/seat/month billed monthly or $9/seat/month billed annually for unlimited seats, projects, and clients. 30-day free trial on paid plans. Harvest does not process payments directly; invoices include a "Pay Online" option via Stripe or PayPal that you configure.

Best for: VAs who track time across many clients and projects weekly and want the shortest path from tracked hours to a sent invoice. VAs already using project management tools like Asana or Trello who want time tracking data to flow into invoices without switching platforms.

Tradeoff: Harvest is a time tracking tool with invoicing attached, not an invoicing platform with time tracking built in. It lacks recurring invoices for retainer clients, has no contracts or proposals, no CRM, and no client portal. If you run retainer clients alongside hourly clients, you need a separate tool for the recurring billing. The free plan's 2-project cap means any VA with more than 2 clients hits the paywall immediately.

5. Zoho Invoice: Best Free Multi-Currency Option for International VAs

Zoho Invoice is the strongest free invoicing platform for VAs billing clients across multiple countries. It supports 15+ currencies with automatic exchange rates, recurring invoices, time tracking, and client portals on the free tier for businesses under $20,000 in annual revenue.

Key features:

• 15+ currencies with automatic exchange rate conversion
• Recurring invoices with autopay
• Built-in time tracking with project tagging
• Client portal with invoice history and document sharing
• Mobile apps for iOS and Android with offline invoice creation

Pricing: Free for small businesses under published revenue and client caps. Zoho Billing premium plans start at $9/month annually for unlimited clients and advanced subscription management. No per-user fees on any tier.

Best for: VAs based in the Philippines, India, Latin America, or Eastern Europe billing US, UK, and EU clients in multiple currencies. VAs under the free-tier revenue cap who want professional multi-currency invoices without paying for the feature.

Tradeoff: Zoho Invoice is invoice-first: no native contracts, no proposals, and no bookkeeping module (that lives in the separate Zoho Books product). The free tier has revenue and client caps that a growing VA will hit within 12-18 months. Integrations into Zoho's wider suite are powerful but add complexity that a single-product user does not need.

6. Bonsai: Best for US Freelance VAs Who Want Tax Help

Bonsai bundles contracts, proposals, invoicing, time tracking, and basic bookkeeping in one product. Its US tax estimation feature (Schedule C-friendly quarterly tax reminders and expense categorization) is the strongest differentiator for solo VAs filing as sole proprietors in the United States.

Key features:

• VA contract and proposal templates with e-signatures
• Recurring invoices and payment plans
• Time tracking with automatic billable-hour sync to invoices
• US quarterly tax estimation and expense categorization
• Client portal with shared resources and project status

Pricing: Basic at $15/user/month or $9/user/month annually (no invoicing or contracts). Essentials at $25/user/month or $19/user/month annually (invoicing, contracts, client portal). Premium at $39/user/month or $29/user/month annually (workload management, integrations). Elite at $59/user/month or $49/user/month annually (team features, minimum 3 users). 7-day free trial on all plans. Note: Zoom acquired Bonsai in December 2025; long-term roadmap is now under enterprise ownership.

Best for: US-based solo VAs who want contracts, invoicing, time tracking, and quarterly tax estimates in a single dashboard without separate accounting software.

Tradeoff: The per-user pricing model means adding even one subcontractor doubles the monthly cost. Multi-currency support is thinner than Zoho or Agiled. International VAs will find Bonsai more US-centric than its competitors. The Essentials plan at $25/month is the minimum viable tier since Basic lacks invoicing entirely.

7. HoneyBook: Best for VAs Running Multi-Service Businesses

HoneyBook bundles proposals, contracts, invoices, scheduling, and a client portal in a polished interface designed for client-facing service businesses. Its "Smart Files" combine the proposal, the contract, and the invoice into a single document the client signs and pays in one flow.

Key features:

• Smart Files (proposal + contract + invoice in one branded document)
• Recurring invoices and installment payment plans
• Integrated payments with 2.9% + $0.25 card fee, 1.5% ACH
• Client portal with document and communication history
• Mobile app with inquiry notifications and on-the-go invoicing

Pricing: Starter at $36/month monthly or $29/month annually. Essentials at $59/month monthly or $49/month annually. Premium at $129/month monthly or $109/month annually. 7-day free trial. HoneyBook raised pricing 63-89% across plans in February 2025.

Best for: VAs who offer multi-service packages (virtual assistance plus social media management, plus bookkeeping, plus inbox management) and want one branded client experience from proposal through final payment.

Tradeoff: No built-in time tracking. A VA billing hourly needs a separate time tracker, which defeats the purpose of an all-in-one platform. The February 2025 price hike made HoneyBook noticeably more expensive than Agiled or Dubsado for equivalent features. At $29/month (annual), HoneyBook costs more per month than some VAs earn per hour.

8. Dubsado: Best for VAs With Complex Client Onboarding

Dubsado is the platform most chosen by VAs who want maximum control over client onboarding and invoice automation. Conditional workflows let you trigger an invoice only when specific conditions are met: contract signed AND intake form completed AND onboarding call scheduled.

Key features:

• Conditional workflow builder with if-then-else logic on invoice triggers
• Recurring invoices and custom installment plans
• Fully customizable invoice and contract templates with brand fonts and colors
• Scheduler with round-robin for VA teams and group booking
• Integrated payments via Stripe, Square, and PayPal

Pricing: Starter at $35/month or $335/year (core features, no automations). Premier at $55/month or $525/year (automations, scheduling, integrations). Annual billing saves roughly two months. 21-day free trial with full access to Premier features. Additional brands at $10/month each.

Best for: Established VAs running 10+ client engagements where client onboarding involves multiple steps (intake form, contract, scope doc, first invoice) and each step needs to trigger the next automatically.

Tradeoff: No built-in time tracking. The configuration curve is steep: expect 10-20 hours of initial setup before Dubsado workflows pay off. For a VA billing 3-4 clients on simple hourly invoices, Dubsado is over-engineered. The minimum viable plan at $35/month is expensive for a new VA.

9. QuickBooks Solopreneur: Best for Tax-Ready Bookkeeping With Invoicing

QuickBooks Solopreneur (formerly QuickBooks Self-Employed) is the strongest choice for VAs who prioritize tax preparation and clean bookkeeping over invoicing features. It separates personal and business expenses, estimates quarterly taxes, and produces Schedule C-ready reports that make April painless.

Key features:

• Mileage tracking (auto-detection via GPS) and expense categorization
• Basic invoicing with recurring invoice support
• Automatic separation of personal and business transactions
• Quarterly tax estimation for US sole proprietors
• Integration with TurboTax for direct filing

Pricing: Solopreneur starts at approximately $20/month. Higher tiers (Simple Start at $35/month, Essentials at $65/month) add multi-user access and more advanced accounting features. 30-day free trial. Frequent promotional pricing at 50-70% off for the first 3 months.

Best for: US-based VAs who file Schedule C and want their invoicing tool to double as their bookkeeping and tax prep system. VAs whose accountant already uses QuickBooks and needs clean data imports.

Tradeoff: QuickBooks Solopreneur is an accounting tool that happens to have invoicing, not an invoicing tool with accounting. The invoice builder is functional but basic compared to FreshBooks or Agiled. No contracts, no proposals, no client portal, and no CRM. Time tracking is rudimentary. If invoicing is your primary need, you are paying for accounting features you may not use.

10. Paymo: Best Combined Task Manager and Invoicing for Solo VAs

Paymo combines project management, time tracking, and invoicing in a single platform designed for freelancers and small teams. For solo VAs who manage tasks, track time, and generate invoices within the same workflow, Paymo eliminates the app-switching that kills productivity.

Key features:

• Task management with Kanban boards, calendar views, and Gantt charts
• Time tracking with per-project and per-task rates that feed directly into invoices
• Invoicing with detailed hour breakdowns and professional formatting
• Client payments via Stripe, PayPal, or direct debit
• Resource scheduling and project profitability reports (on higher plans)

Pricing: Free plan for 1 user with unlimited time tracking and invoices, limited to 2 projects and 1 client. Solo at $9.90/month for 1 user (up to 3 clients and 5 projects). Plus at $15.90/user/month for unlimited users, clients, and projects. Pro at $23.90/user/month for Gantt charts, scheduling, and priority support. New accounts get 40% off for the first 3 months on monthly plans.

Best for: Solo VAs who want task management, time tracking, and invoicing in one platform without paying for features they do not need. VAs who like managing work visually with Kanban boards and want their tracked time to flow directly into client invoices.

Tradeoff: The free plan's 1-client cap is immediately limiting for any working VA. No contracts, no proposals, and no client portal. The invoicing templates are functional but less polished than FreshBooks or HoneyBook. Paymo's strength is the project management side; if you only need invoicing, it is more tool than necessary.

11. Square Invoices: Best Free Unlimited Invoicing With No Client Cap

Square Invoices offers unlimited free invoicing with no cap on the number of clients, invoices, or estimates. For VAs who want a simple, no-cost invoicing tool that sends professional invoices and collects card payments without a monthly subscription, Square is the fastest path from "I need to bill this client" to "payment received."

Key features:

• Unlimited invoices, estimates, and basic contracts on the free tier
• Recurring invoices and payment schedules
• Card payments at 2.9% + $0.30, ACH at 1% on qualifying invoices
• Mobile app with invoice creation and payment tracking
• Milestone-based payment schedules on the Plus plan ($20/month)

Pricing: Free plan with unlimited invoices and clients. Plus plan at $20/month adds custom templates, batch invoicing, multi-package estimates, and advanced automation.

Best for: VAs who want zero-cost invoicing with no client cap and do not need time tracking, CRM, or contracts integrated into the same platform.

Tradeoff: No built-in time tracking. No CRM, no client portal beyond invoice viewing, and no project management features. Square's invoicing is a standalone billing tool. A VA using Square still needs separate tools for time tracking, contracts, and client communication, which creates the same multi-tool friction that all-in-one platforms like Agiled eliminate.

Original Research: Annual Invoicing Cost Per Client Across 8 Platforms

We built a cost model for a solo VA with 8 active clients at an average monthly billing of $1,200 per client ($9,600/month total, $115,200 annual revenue through the invoicing tool). We calculated the total annual cost of the platform subscription plus realistic payment processing fees across 96 monthly invoices per year (8 clients x 12 months).

Assumptions: 8 active clients, 12 months of billing, 96 total card charges per year, average invoice amount of $1,200, ACH not used, annual billing on subscriptions where available. Processing rates as published by each platform; where a platform defers to Stripe, we use 2.9% + $0.30 per transaction.

Reading the table: The headline subscription price is not where the money is for a VA at volume. Payment processing at 2.9% + $0.30 dominates the cost: $3,370+ per year on $115,200 of revenue before you pay a dollar of subscription. The right question is not "what is the cheapest invoicing tool" but "which tool recovers the most of that $3,370 in value through adjacent features I would otherwise buy separately."

Break-even math on upgrading from free tools to Agiled: If your alternative is the free Wave stack plus Toggl Track Starter ($9/mo) plus a separate CRM ($0-$25/mo) plus a contracts tool like DocuSign ($15/mo), you are already paying $288-$588/year in stacked tools with no integration between them. Agiled Pro ($300/year) replaces that stack entirely and adds CRM, contracts, scheduling, and client portals in one login. The break-even is within the first month. You save $0-$288/year on tool spend and recover 1-3 hours per week of manual reconciliation across disconnected apps.

Wave's hidden processing fee cost: Wave's per-transaction fee of $0.60 (versus Stripe's standard $0.30) adds $28.80/year in extra fees on 96 transactions. Over 3 years of VA work, that is $86.40 in fees that a tool using standard Stripe pricing would not charge. At VA margins, that is the cost of a meal or a subscription to another tool.

How Virtual Assistants Lose Money on Invoicing (And How to Fix It)

Four operational failures account for most of the invoicing revenue leak in a working VA practice. Name each one and wire your tool to prevent it.

1. The missed hourly invoice. You track 12.5 hours for Client B across the week but forget to invoice until the following Monday. Client B's payment cycle resets and the invoice now arrives on day 1 of a new billing period instead of the last day of the old one. The client's accounts payable process adds 14 days. Net result: $437 sits in limbo for three weeks. Fix: set a recurring Friday afternoon reminder or, better, use a tool that auto-generates invoices from tracked time at the end of each billing cycle (FreshBooks, Harvest, and Agiled all support this).

2. The cross-client contamination error. You invoice Client A but accidentally include 2.5 hours that were tagged to Client C's project because you mis-clicked the project label during a hectic Tuesday. Client A receives a $87.50 overcharge, notices, and questions your attention to detail. The correction takes 30 minutes of back-and-forth plus a credit note. Fix: use per-project timers with separate client workspaces. Agiled and Harvest both enforce project-level separation that makes cross-tagging harder to miss.

3. The retainer renewal slip. Client D's 6-month retainer ends in October. You forget to send the renewal invoice. Client D assumes the engagement is over and starts interviewing your replacement. By the time you notice in November, the client has signed with another VA. Cost: $12,000 in lost annual revenue from one client. Fix: set a recurring invoice with an end date and a workflow trigger that fires a renewal proposal 30 days before expiration. Agiled's workflow automation and Dubsado's conditional workflows handle this directly.

4. The international payment rail mistake. You bill a UK client in USD because your invoicing tool does not support GBP. The client's bank converts USD to GBP at a retail exchange rate with a 2-3% spread. Your $1,200 invoice effectively costs the client $1,236-$1,260 after conversion, and they ask you to "do something about the exchange rate." Fix: bill in the client's currency using a multi-currency tool (Agiled, Zoho Invoice, or FreshBooks), and connect your payout to Wise or Payoneer to receive the conversion at a near-interbank rate instead of a retail bank rate.

When VA Invoicing Software Is the Wrong Choice

Not every virtual assistant needs a dedicated invoicing platform. Here is when to wait or choose differently.

You have 1-2 clients on simple retainers. A Stripe payment link and a Google Docs receipt template is enough. Paying $25-$49/month for invoicing software when you bill two clients the same amount every month is a premature optimization. Start with Stripe's free invoice feature and upgrade when you cross 4 clients or add hourly billing.

You work through a VA agency that handles billing. If you work through Belay, Time Etc, Boldly, or a similar agency, the agency bills the client and pays you directly. A personal invoicing tool creates duplicate records with no incremental value. Your invoice goes to the agency, not the end client, and many agencies have their own portal for that.

Your clients use their own invoicing system. Some enterprise clients require you to submit invoices through their AP portal (Coupa, Ariba, or a custom procurement system). Your invoicing software produces a PDF that gets re-entered into their system anyway. In that scenario, the client's portal is the invoicing tool, and yours is redundant for that engagement.

You are a VA earning under $500/month total. If you are doing VA work as a side project with 2-3 hours per week per client, the ROI on any paid invoicing tool is negative. Use Wave (free), a Stripe payment link, or even PayPal's built-in invoicing until your monthly revenue justifies the subscription.

Frequently Asked Questions

What is the best free invoicing software for virtual assistants?

Agiled's free plan covers 2 billable clients with invoicing, time tracking, and a client portal built in. Wave is the strongest pure-accounting free tool with unlimited invoices and unlimited clients. Zoho Invoice is the best free multi-currency option for VAs billing international clients. Square Invoices offers unlimited free invoices with no client cap but no time tracking. For a VA with 1-3 paying clients, any of these four cover the workload at $0/month. Upgrade once you cross 4-5 active clients or need integrated contracts and CRM.

How do virtual assistants handle billing for multiple clients with different rates?

Every platform on this list supports per-client rate configuration. The setup varies by billing model. For hourly clients, set a per-project or per-client hourly rate in your time tracking tool (Agiled, FreshBooks, Harvest, Paymo). For retainer clients, create a recurring invoice at the fixed monthly amount. For project-based clients, create a one-time or milestone invoice for the agreed fee. Agiled and FreshBooks handle all three models in the same account without switching workflows.

Should virtual assistants use time tracking software that integrates with invoicing?

Yes. A VA billing 8 clients hourly spends 15-20 minutes per client per week on manual invoice assembly if time tracking and invoicing are disconnected. That is 2+ hours per week of unbillable administrative work. Tools that convert tracked time directly to invoice line items (Agiled, FreshBooks, Harvest, Paymo, Bonsai) eliminate that friction entirely. The integration pays for itself within the first billing cycle.

What payment processing fees should VAs expect on their invoices?

Standard card processing via Stripe is 2.9% + $0.30 per transaction in the US. Wave charges 2.9% + $0.60 (higher per-transaction). HoneyBook charges 2.9% + $0.25 for cards, 1.5% for ACH. Square is 2.9% + $0.30 for cards, 1% for ACH on qualifying invoices. On a $500 hourly invoice, that is $14.80 per month or $177.60 per year per client in processing fees. Offering ACH (often 0.8%-1% with a cap) on retainer invoices over $1,000 saves meaningful money over card processing.

How do international VAs handle invoicing clients in different currencies?

Use a platform with built-in multi-currency support. Agiled and Zoho Invoice both support 15+ currencies with automatic exchange rate conversion on the invoice. FreshBooks also supports multi-currency billing. The invoice goes out in the client's currency (USD, GBP, EUR), and you receive the payout in your local currency through Stripe, PayPal, or Wise. Avoid billing international clients in your own currency: the client's bank conversion adds a 2-3% spread that makes your invoice more expensive than the stated amount.

Do I need separate software for contracts and invoicing as a VA?

Not if you choose the right tool. Agiled (Premium), HoneyBook, Dubsado, and Bonsai all include contracts with e-signatures alongside invoicing. FreshBooks, Wave, Zoho Invoice, Harvest, Paymo, and Square require a separate contracts tool (DocuSign Essentials at $15/mo is the common pairing). For VAs, contracts bundled with invoicing save 2-5 days of delay between "the client says yes" and "the first payment arrives." That delay is where clients ghost.

What is the best invoicing software for a VA team with subcontractors?

For a VA who hires subcontractors, the tool needs multi-user access with role-based permissions so the subcontractor can track their own time without seeing other clients' data. Agiled Pro supports up to 3 users at $25/month. Harvest Teams charges $9-$11/seat/month depending on billing cycle. Bonsai's per-user pricing ($25/user/month) makes it expensive for teams. FreshBooks charges $11/month per additional user. Agiled offers the best value for small VA teams because it includes CRM, client portals, and contracts alongside the multi-user invoicing at no extra per-user charge on the Pro and Premium tiers.

How often should a virtual assistant invoice clients?

Weekly for hourly clients, monthly for retainer clients, and upon milestone completion for project-based clients. Weekly invoicing for hourly work keeps each invoice small enough that clients pay without scrutiny and cash flow stays consistent. Monthly invoicing for retainers is standard and should be set to auto-charge on a fixed date. The biggest mistake VAs make is batching all invoicing to the end of the month: if a payment fails, you have 30 days of revenue at risk instead of 7.

The Bottom Line

For solo VAs and small VA teams, Agiled is the best overall value because it bundles invoicing, time tracking, CRM, contracts, and client portals into one platform starting at $0/month, replacing 3-4 separate subscriptions and removing the reconciliation friction of disconnected tools. If you bill primarily by the hour and need the fastest time-to-invoice conversion, FreshBooks or Harvest give you the tightest pipeline between tracked hours and sent invoices. If you are in your first year with fewer than 4 clients and need $0/month overhead, Wave or Zoho Invoice covers the basics without a subscription. If you bill international clients in multiple currencies, Zoho Invoice is the strongest free multi-currency option.

Whatever you choose, wire three automations on day one: a weekly invoice trigger for every hourly client, a recurring monthly invoice with autopay for every retainer client, and a renewal reminder 30 days before every engagement end date. The difference between a VA earning $36,000/year and one earning $72,000/year is usually not the hourly rate. It is whether the invoicing system catches every billable hour, every renewal, and every failed payment before the client does.
