Assembly (formerly Copilot) starts at $149/month for 3 users and 500 clients. Moxo starts at $200/month for 10 users with 10 workspaces per year and 100 AI credits. Both are client portal platforms, but Assembly is built around a branded portal experience for professional service firms, while Moxo is built around multi-step workflow orchestration for regulated industries.
A note on naming: Copilot rebranded to Assembly in September 2025 after "Copilot" became too generic in the AI era. The product is now officially Assembly at assembly.com. Most users still search "Copilot," so this comparison uses both names where helpful.
This comparison uses official pricing from each platform's website, G2 and Capterra reviews, and documented feature limits as of April 2026.

|---|---|---|
| 3-person firm, 500 clients | $149/mo (Professional) | $200/mo (Business) |

| 10+ person firm | $2,000+/mo (Enterprise) | Custom quote |
Assembly is cheaper for small firms (under 5 people) that need a premium portal. Moxo is cheaper per-seat for teams of 6-10 that prioritize workflow orchestration over portal polish. Both get expensive at scale.
Client portal experience
This is the category where these platforms compete most directly.
Assembly
Assembly treats the client portal as its core product. Clients log into a branded hub to access messages, invoices, contracts, files, forms, and embedded third-party apps. Custom domain support means clients visit yourfirm.com instead of a generic SaaS subdomain. The App Store lets you embed tools like Calendly, Airtable, and Google Data Studio directly inside the portal so clients never leave your branded environment.
Multiple G2 reviewers describe the portal as feeling like a "custom-built app" rather than off-the-shelf software. The UI is clean and modern, with magic links or Google SSO for frictionless access.
The trade-off: the portal's customization options are somewhat rigid beyond branding. Users have requested more layout control, and there is no native mobile app for clients or admins. Push notifications and native widgets require workarounds.
Moxo
Moxo's portal is a secure, white-labeled environment focused on workflow completion rather than general-purpose access. Clients log in to upload documents, review and sign contracts, track workflow progress, join video meetings, and exchange messages tied to specific workflow steps. The audit trail tracks every interaction, which matters in regulated industries.
Moxo has a mobile app, which Assembly currently lacks. But white-label branding and custom domain are gated behind add-on pricing or higher tiers, while Assembly includes custom domain on its base paid plan.
The trade-off: Moxo's portal is workflow-driven. If a client just needs to check an invoice, send a message, or view a file outside of an active workflow, the experience is less intuitive than Assembly's always-on portal.
Verdict
Assembly's portal is broader and more polished for daily client interaction. Moxo's portal is more structured and auditable for regulated, multi-step processes. If your clients log in regularly to check updates, Assembly feels better. If your clients only interact during specific onboarding or compliance sequences, Moxo fits better.
Workflow automation
Assembly
Assembly does not have a visual workflow builder with conditional branching. Automations exist for internal processes like assigning tasks when a contract is signed or triggering follow-ups, but they are lightweight compared to dedicated workflow platforms. If you need "if client uploads document A, then route to approver B, then trigger step C," Assembly cannot do that natively.
Moxo
Moxo's workflow engine is its defining feature. The visual builder supports multi-step processes with conditional branching, parallel paths, dependencies, and automated routing. Workflows can include document requests, e-signature steps, form submissions, video meetings, and approval gates, all sequenced and tracked in real time.
The AI workflow builder generates templates from natural language descriptions, consuming AI credits (100 included on Business). Workflows are reusable and can be triggered automatically or manually.
The gotcha: Moxo's Business plan caps you at 10 workspaces per year. If you onboard more than 10 clients annually, you either need to structure your workflows carefully or upgrade to Enterprise (custom pricing, not published). The learning curve is also steep. Multiple G2 reviewers report that building conditional workflows "took longer than expected" and requires "a real investment in learning the platform."
Verdict
If conditional, multi-step workflow orchestration is your primary need, Moxo is purpose-built for it. Assembly's automation is basic by comparison. If you just need a portal that triggers simple task sequences when events happen, Assembly is sufficient and far easier to set up.
CRM and client management
Assembly
Assembly includes a built-in CRM with a central dashboard for all clients, projects, and billing. The AI Assistant knows your client history, can summarize activity, and helps prep for meetings. Client data, communication history, and financial data live in one workspace. For professional service firms that want client management and portal access in the same tool, Assembly consolidates what would otherwise require 2-3 separate products.
Moxo
Moxo does not include a CRM. It connects to external CRMs via API, webhooks, or Zapier, but client relationship data, sales pipelines, and deal tracking live elsewhere. Moxo handles the operational side (workflows, documents, signatures) but not the relationship side.
Verdict
If CRM is a requirement, Assembly includes it natively. Moxo requires a separate CRM tool, which adds cost and integration complexity.
Invoicing and payments
Assembly
Assembly includes built-in invoicing with one-click invoice creation, subscription billing, and online payment collection. Invoices live inside the client portal alongside contracts, messages, and files.
Moxo
Moxo does not include native invoicing. Payment processing (like Stripe) connects through integrations and incurs standard processing fees (typically 2.9% + $0.30 per transaction). Invoicing requires a third-party tool.
Verdict
Assembly handles invoicing natively. Moxo does not. If getting paid is part of your client workflow, Assembly saves you an additional subscription.
Security and compliance
| Certification | Assembly | Moxo |
|---|---|---|
| SOC 2 Type II | Yes | Yes |
| GDPR | Yes | Yes |
| HIPAA (BAA) | Yes (Advanced plan) | No |
| Audit trails | Basic | Comprehensive (every interaction logged) |
| Data encryption | In transit + at rest | In transit + at rest |
| Custom data residency | No | Yes (Enterprise) |
Assembly's HIPAA compliance with a signed BAA makes it the only option here for healthcare-adjacent firms. Moxo's audit trail depth and custom data residency make it stronger for financial services and legal firms that need granular interaction logging across multi-party workflows.
Who should NOT choose Assembly
- Teams needing conditional workflow orchestration. Assembly's automation is lightweight. If your business runs multi-step, branching approval processes with parallel tasks, Assembly will frustrate you.
- Firms needing a mobile app. Assembly currently has no native mobile app for clients or admins. If your clients expect push notifications and mobile-native access, this is a gap.
- Budget-conscious small teams. $149/month for 3 users is steep if you only need basic client communication. Simpler tools exist at lower price points.
- Teams needing deep third-party integrations. Assembly's integration ecosystem is narrower than established CRMs. If you rely on dozens of prebuilt connectors, check the App Store first.
Who should NOT choose Moxo
- Firms that need a CRM. Moxo has no client relationship management. You will need a separate CRM, adding $50-150+/month to your stack.
- Teams that need invoicing. No native invoicing means another subscription and another integration point.
- Small businesses watching costs. $200/month with a 10-workspace/year cap and 10 GB storage can get expensive fast. White-label branding, custom domain, and 24/7 support are all add-ons.
- Teams wanting fast setup. Multiple reviewers report a steep learning curve. If you need to be live in days rather than weeks, Moxo will slow you down.
- Firms needing HIPAA compliance. Moxo does not offer a BAA. Healthcare-adjacent businesses should look elsewhere.
What real users say
Assembly (formerly Copilot)
G2: 4.7/5 (300+ reviews) | Capterra: 4.6/5
Praise centers on the portal experience: "The client portal is highly customizable, allowing clients access to pertinent information 24/7, reducing FAQ responses." Another reviewer: "It feels like a custom-built app."
Common complaints: no mobile app, limited layout customization beyond branding, and pricing that "can be expensive for what it offers compared with similar customer portal tools." Some users note the platform is "still fairly new and lacks features" they expect will be added over time.
Moxo
G2: 4.5/5 (194 reviews, 78% five-star) | Capterra: 4.2/5
Praise focuses on workflow automation and client portals: "The client portal is sleek and professional" and "streamlined our client onboarding from weeks to days."
Common complaints: steep learning curve ("starting requires a lot of time and effort"), limited integrations beyond CRM and Google Drive on the base plan, billing disputes with customer service, and the 10-workspace/year cap forcing careful planning. One reviewer described the customer service experience around payment issues as "frustrating from the start."

When neither tool is enough: consider Agiled
Both Assembly and Moxo focus on the client-facing side of your business. Neither offers full project management with Gantt charts and task dependencies, time tracking that flows into invoices, HR/payroll, or a proposals-to-project pipeline. If you are combining 3-4 tools to cover these gaps, the total cost and integration overhead add up.
Agiled is a single platform covering CRM, client portal, project management, time tracking, invoicing, proposals, contracts, and HR.
| Feature | Assembly | Moxo | Agiled |
|---|---|---|---|
| Starting price | $149/mo (3 users) | $200/mo (10 users) | Free (1 user), $25/mo Pro |
| CRM | Yes | No | Yes |
| Client portal | Yes (custom domain) | Yes (branded) | Yes (branded) |
| Project management | Basic tasks | No | Kanban, Gantt, dependencies |
| Time tracking | No | No | Yes (flows into invoices) |
| Invoicing | Yes | No | Yes |
| Proposals and contracts | Yes | No | Yes (AI drafting) |
| HR/Payroll | No | No | Yes (Business plan) |
| Workflow automation | Basic | Full conditional branching | Visual workflow builder |
| E-signatures | Yes | Yes | Yes |
Agiled does not match Assembly's portal polish or Moxo's depth in regulated-industry workflow orchestration. But if your primary need is running a service business end-to-end, from lead capture through project delivery to getting paid, Agiled covers more ground than both tools combined at a fraction of the cost.
Frequently asked questions
Are Assembly and Moxo the same type of tool?
Both are client-facing platforms, but they solve different problems. Assembly (formerly Copilot) is a branded client portal with built-in CRM, invoicing, contracts, and messaging. Moxo is a workflow orchestration platform with conditional branching, document routing, and compliance-grade audit trails. Assembly is broader but shallower on automation. Moxo is deeper on workflows but lacks CRM, invoicing, and the polished always-on portal experience.
How much does Assembly cost compared to Moxo?
Assembly Professional starts at $149/month for 3 users and 500 clients. Assembly Advanced is $399/month for 5 users with unlimited clients and HIPAA compliance. Moxo Business starts at $200/month for 10 users with 10 workspaces per year and 100 AI credits. Moxo's per-seat cost is lower for teams of 6-10, but Assembly includes CRM and invoicing that Moxo does not, potentially saving you $50-150/month on separate tools.
Can Assembly handle complex workflow orchestration?
No. Assembly's automation is limited to basic triggers and task assignments. It does not support conditional branching, parallel workflow paths, or multi-step approval routing. If you need that level of workflow control, Moxo is the better fit, or you can pair Assembly with a dedicated workflow tool.
Is Moxo good for small businesses?
Moxo can work, but the $200/month entry point, 10-workspace-per-year limit, 10 GB storage cap, and add-on pricing for white-label branding and custom domain make it a significant commitment. Moxo is best suited for firms in regulated industries where auditable workflows and SOC 2 compliance are non-negotiable requirements.
Does either platform offer project management or time tracking?
Neither offers full project management with Gantt charts, task dependencies, or resource allocation. Assembly includes basic task management within its CRM. Neither offers time tracking. If you need project management and time tracking alongside client portals, a platform like Agiled covers all three.
What happened to Copilot? Is it the same as Assembly?
Copilot rebranded to Assembly in September 2025. The product, team, and features are the same. The rename happened because "Copilot" became too generic after Microsoft Copilot, GitHub Copilot, and dozens of other AI tools adopted the name. The platform is accessible at assembly.com.
