9 Best Assembly (Copilot) Alternatives in 2026

Assembly (formerly Copilot, rebranded September 2025): branded client portal. Starter $39/mo (50-client cap), Professional $149/mo (3 seats, 500 clients, custom domain), Advanced $399/mo (unlimited, full white-label, HIPAA with BAA). Stripe pass-through fees. No interactive proposal builder, no native scheduling, no real project management. Top pick: Agiled (free tier, proposals, projects, invoicing, HR included).

Assembly (the client portal platform formerly known as Copilot, rebranded in September 2025) gives your clients a polished, white-labeled hub to access messages, invoices, contracts, files, forms, and embedded third-party apps. The portal is genuinely strong: custom domain on Professional, full branding removal on Advanced, HIPAA compliance with a BAA, SOC 2 Type II across all plans, and custom app embedding for tools like Calendly, Airtable, and ClickUp.

The constraints show up fast. The $39/month Starter plan caps at 50 clients, and the next tier jumps 282% to $149/month. Assembly has no interactive proposal builder (its "proposals and contracts" feature is document upload and e-sign, not a pricing-table builder), no native scheduling (you embed Calendly via custom apps), no real project management beyond basic tasks, and only basic contact management rather than a CRM pipeline. Note this is a different product from the employee-recognition platform at joinassembly.com.

If you need a client portal that also handles proposals, projects, and scheduling without bolting on extra subscriptions, here are 9 alternatives worth evaluating.

Quick decision guide:

Deep white-label flat-rate portal	SuiteDash	$19/mo
Agency portal with billing	AgencyPro	$99/mo

Solo proposals plus portal	Plutio	$19/mo
Budget portal plus CRM	Flowlu	Free

Why Teams Switch From Assembly

Assembly's portal is well loved (4.8/5 on G2 from 279 reviews), but specific gaps push teams toward alternatives.

• The 50-client cap and the price cliff. Starter ($39/month) caps at 50 clients. A freelancer who retains past clients hits that ceiling within a year, and the only way up is Professional at $149/month, a 282% increase. Extra internal users cost $39 each on Professional and $59 each on Advanced.
• No interactive proposal builder. Assembly handles contracts and e-signatures, but "proposals" means uploading and signing documents (PDFs, SOWs), not building a proposal with configurable pricing options. The pre-sale "here is what we will do and what it costs" document needs a separate tool.
• No native scheduling. Assembly has no built-in booking. You embed Calendly or another scheduler via custom apps, which means an additional subscription.
• No real project management. Beyond basic tasks, there are no Kanban boards, Gantt charts, dependencies, or milestones. Clients see documents and payments in the portal, not project progress.
• It is a portal, not a CRM. Assembly offers basic contact management with no visual pipeline, deal stages, lead scoring, or forecasting.
• No time tracking that flows to invoices. There is no integrated timer feeding billable hours into invoices.

The Real Cost of Assembly: Portal Plus the Tool Stack

Assembly's portal pricing looks reasonable until you add the tools it does not include. Here is a typical 3-seat agency setup.

Assembly stack	Monthly cost
Assembly Professional (3 seats, 500 clients)	$149/mo
Proposals (Proposify)	$49/mo
Scheduling (Calendly Teams)	~$48/mo
Project management (Asana)	~$33/mo
Estimated total	~$279/mo

Agiled stack	Monthly cost
Agiled Pro (3 seats, all features)	$59/mo
Total	$59/mo

Assembly's portal experience is deeper than Agiled's on white-label branding and HIPAA. But for teams that need proposals, scheduling, and project management alongside the portal, the all-in-one approach removes three subscriptions and the integration overhead between them.

1. Agiled - Best All-in-One Client Portal Platform

Agiled is the strongest alternative because it pairs a branded client portal with the full business platform Assembly leaves out: proposals, contracts, project management, invoicing, CRM, time tracking, and HR.

Clients log into a branded portal to view projects, invoices, proposals, contracts, files, and support tickets. Behind it, signed proposals auto-create projects with tasks, time tracked on those tasks flows into invoices, and the CRM pipeline tracks every deal from lead to payment. Where Assembly stops at the portal layer, Agiled runs the whole client lifecycle.

What makes Agiled the top pick:

• Branded client portal with custom domain and granular permissions
• Proposals with AI drafting and interactive pricing, which Assembly lacks
• Contracts with e-signatures and audit trails
• Project management with Kanban, Gantt, dependencies, and milestones
• CRM with deal pipelines and automation
• Invoicing with recurring billing and online payments
• Time tracking that converts to invoice line items
• Scheduling with booking pages, built in (no embed required)
• HR for employee management, attendance, and leave

Pricing: Limited free workspace available. Starter is $24/month billed annually for 1 seat. Pro is $59/month billed annually for 3 seats. Premium is $99/month billed annually for 7 seats. Business is $199/month billed annually for 15 seats.

Not for you if: You need Assembly's depth of white-label portal branding, custom app embedding, or HIPAA compliance with a signed BAA. Agiled offers a branded portal but does not match Assembly's portal-first polish or healthcare compliance.

2. SuiteDash - Best Flat-Rate White-Label Portal

SuiteDash is the closest match to Assembly's white-label ambition, bundling CRM, invoicing, project management, file sharing, and client portals under your own brand, with flat-rate pricing that means unlimited team members and clients on every plan.

Key features:

• Fully white-label portal with custom domain and branded mobile app
• CRM and invoicing
• Project and task management
• File sharing and secure messaging
• Flat-rate pricing (no per-client caps)

Limitations: Reviewers report slow page loads and a multi-week setup. Key automations require the top Pinnacle plan. No interactive proposal builder with AI drafting.

Pricing: Start at $19/month, Thrive at $49/month, Pinnacle at $99/month, all flat-rate with unlimited users and clients.

3. AgencyPro - Best for Agency Portal and Billing

AgencyPro is purpose-built for agencies that need a fully branded client portal with CRM, project management, invoicing, and billing in one place, with a faster setup than Assembly's portal plus separate tools.

Key features:

• Branded client portal with custom domain
• CRM with complete client profiles
• Project management in list, Kanban, and queue views
• Automated invoicing with Stripe and PayPal
• Design annotation and file proofing
• Credit-based and hourly service packages

Limitations: Starting price of $99/month is high for solo freelancers. Advanced features like API and Zapier require the Plus plan. Built for service businesses, not product teams.

Pricing: Basic at $99/month (2 seats). Pro at $199/month (5 seats). Plus at $399/month (10 seats).

4. Moxo - Best for Enterprise Client Interaction

Moxo is a client interaction platform built around secure portals, digital workflows, document collaboration, e-signatures, and approvals, used heavily in financial services, legal, and consulting where compliance matters.

Key features:

• Branded client portal with secure messaging
• Digital workflow automation (actions, approvals, signoffs)
• Document collaboration and e-signatures
• Mobile apps for clients and staff
• Compliance-oriented security controls

Limitations: Pricing is quote-based (contact sales), so costs are not transparent upfront. No native invoicing or proposal builder with pricing tables. Heavier than most solo freelancers need.

Pricing: Custom pricing, contact sales.

5. Plutio - Best for Solopreneurs

Plutio connects proposals, contracts, project management, and invoicing with a client portal that auto-converts signed documents into projects, covering the proposal workflow Assembly lacks.

Key features:

• Proposals and contracts that convert to projects when signed
• Time tracking with billable rates
• Client portal with project progress
• Task management with boards and lists
• Integrated invoicing and payments

Limitations: Limited HR and team management. Brand customization is less extensive than Assembly, with no white-label mobile app. Better suited to solos than larger agencies.

Pricing: Starts at $19/month for solo users. Team plans from $39/month.

6. Dubsado - Best for Custom Client Workflows

Dubsado offers deep customization for client workflows, forms, proposals, contracts, and automation, with client portals for document access, all of which extend beyond Assembly's document-and-payment portal.

Key features:

• Highly customizable proposals, contracts, and forms
• Workflow automation with branching logic
• Client portals for document access
• Invoicing with payment plans
• Scheduler with availability settings

Limitations: No project management or time tracking. Setup can be time-consuming for complex workflows. Interface feels dated. Free plan limited to 3 clients.

Pricing: Starter at $35/month. Premier at $55/month. Free plan for up to 3 clients.

7. HoneyBook - Best for Booking and Payments

HoneyBook is a client management platform centered on the proposal-to-payment booking flow for creative professionals, with Smart Files that combine proposals, contracts, and invoices into one signable document, which Assembly cannot replicate.

Key features:

• Smart Files (proposal, contract, invoice in one flow)
• Online payments with payment schedules
• Automated workflow templates
• Visual booking pipeline
• Built-in scheduler (Essentials and above)

Limitations: No real project management or time tracking that flows to invoices. Portal shows documents and payments, not project progress. US and Canada only. No HIPAA compliance.

Pricing: Starter at $36/month ($29 annual). Essentials at $59/month. Premium at $129/month.

8. Flowlu - Best for Budget-Conscious Teams

Flowlu is an affordable all-in-one combining CRM, project management, finance, invoicing, a knowledge base, and a client portal. Its free tier for up to 2 users makes it the most budget-friendly Assembly alternative that still covers CRM and projects.

Key features:

• CRM with deal pipelines
• Project management with tasks and milestones
• Invoicing and expense tracking
• Knowledge base and client portal
• Quotes and estimates

Limitations: Interface is less polished than Assembly. White-label customization is more limited, with no branded mobile app or HIPAA compliance.

Pricing: Free for up to 2 users. Team from $8/user/month.

9. Bonsai - Best for Freelance Finances

Bonsai combines client management with strong financial tools, including US tax preparation, for freelancers who want contracts, proposals, invoicing, and a client experience without the cost of a portal-first platform.

Key features:

• Contracts and proposals with e-signatures
• Invoicing with automatic payment reminders
• Expense tracking and US tax preparation
• Time tracking with project budgets
• Client CRM with automated follow-ups

Limitations: Task management is basic. Tax features are US-only. No fully branded white-label portal. Not designed for larger teams.

Pricing: Starter at $21/month. Professional at $32/month. Business at $66/month.

How These 9 Platforms Compare on Core Capabilities

We compared each platform on what Assembly users ask about when switching: branded client portal, proposals, project management, invoicing, white-label depth, and starting price.

Platform	Client Portal	Proposals	Projects	Invoicing	White-Label	Starting Price
Agiled	Yes	AI builder	Yes	Yes	Yes	Free
SuiteDash	Yes	Limited	Yes	Yes	Full (+app)	$19/mo
AgencyPro	Yes	Yes	Yes	Yes	Yes	$99/mo
Moxo	Yes	No	Workflows	No	Yes	Custom
Plutio	Yes	Yes	Yes	Yes	Limited	$19/mo
Dubsado	Yes	Yes	No	Yes	Logo/colors	$35/mo
HoneyBook	Secondary	Smart Files	Basic	Yes	Logo/colors	$36/mo
Flowlu	Yes	Quotes	Yes	Yes	Limited	Free
Bonsai	No	Yes	Basic	Yes	No	$21/mo

Agiled is the only option that pairs a branded portal with an AI proposal builder, full project management, invoicing, and HR while offering a free plan. SuiteDash and AgencyPro come closest on white-label portal depth.

When Assembly Is Still the Right Choice

Assembly remains the better tool in specific situations.

• The portal is your product. If clients living inside a polished, custom-domain hub is the experience you sell, Assembly's portal-first design is best in class.
• You need custom app embedding. Assembly lets you embed Calendly, Airtable, ClickUp, Loom, and more directly in the portal, so clients access everything in one branded place.
• You handle protected information. Assembly offers HIPAA compliance with a signed BAA on the Advanced plan and SOC 2 Type II across all plans, which matters for healthcare, therapy, legal, and financial advisory work.
• You collect large ACH payments. Assembly's Stripe pass-through caps ACH fees at $5 per transaction, which saves significantly versus platforms that charge an uncapped percentage.

If your needs extend past the portal into proposals, scheduling, and project delivery, the alternatives above cover more ground for less.

What Is the Best Overall Pick in 2026?

Agiled is the best overall pick because it gives clients a branded portal while running the full lifecycle Assembly leaves out: proposals with AI drafting, contracts, project management, invoicing, scheduling, CRM, and HR, all with transparent tier pricing and a free plan.

If a white-labeled, compliance-ready portal is the entire point of the product, Assembly, SuiteDash, or Moxo are the right tools. But for teams that need the portal plus the work that surrounds it, Agiled delivers more value at a fraction of the multi-tool cost.

Frequently Asked Questions

Is Assembly the same as Copilot?

Yes. The client portal platform at assembly.com is the former Copilot, rebranded in September 2025. It is a different, unrelated product from the employee recognition and engagement platform at joinassembly.com.

How much does Assembly cost?

Assembly has three plans: Starter at $39/month (1 user, capped at 50 clients), Professional at $149/month (3 seats, 500 clients, custom domain, extra users $39 each), and Advanced at $399/month (unlimited clients, full white-label, HIPAA with BAA, extra users $59 each). Payment processing passes through Stripe fees (2.9% + $0.30 per card, 0.80% per ACH capped at $5).

Does Assembly have a proposal builder?

No. Assembly handles contracts and e-signatures, but its "proposals" feature is document upload and signing, not an interactive proposal builder with configurable pricing options. Agiled, Plutio, Dubsado, and Bonsai all include true proposal builders.

Does Assembly include scheduling or project management?

Assembly has no native scheduling (you embed Calendly via custom apps) and no real project management beyond basic tasks. Agiled, SuiteDash, AgencyPro, and Plutio include both scheduling and project management natively.

What is the best Assembly alternative for an agency?

Agiled is the strongest all-around choice, adding proposals, projects, invoicing, and HR to a branded portal at transparent pricing. For a flat-rate white-label portal with unlimited clients, SuiteDash is the closest match. AgencyPro suits agencies that want a portal with credit-based billing and design proofing.
