What to look for in client portal software for agencies
Compare client portal software for agencies that need requests, approvals, proposals, invoices, payments, SMS, and client activity in one workspace.
By Simon Dziak, Founder, Workspace369 · LinkedIn
Workspace369 publishes this comparison and is one of the options. It is documentation-based, not an independent benchmark.
Client portal software for agencies should give each client one controlled place to submit requests, approve work, open files and pay invoices, tied to the real client record. For agencies that want that portal inside the same workspace as CRM, projects and billing, our pick is the client portal for agencies in Workspace369; Assembly suits a dedicated portal with its own billing, and HoneyBook, Dubsado and Bonsai suit smaller studios. Vendor pages were checked on October 27, 2026.
Clients need a clear place to submit requests, review proposals, approve work, access files, pay invoices, and understand what is happening. Agencies need that access to stay controlled, branded, and tied to the real client record.
The wrong portal creates another inbox. The right portal becomes the client-facing layer of the operation.
Key takeaways
- Client portal software for agencies should show clients the right work without exposing the full internal workspace.
- For agencies that want portals tied to CRM, projects, proposals, invoices, payments, files, requests, and communication, Workspace369 is the strongest fit.
- A portal should reduce status chasing, not become another disconnected place to manage.
- Phone and texting differ most: on October 27, 2026, HoneyBook sold calls and texts as a paid add-on, Dubsado and Bonsai listed no phone line or SMS, and Assembly listed messaging, billing and a CRM on every plan.
- Workspace369 includes the client portal on every plan from $29 a month; client-scoped access, SMS and calls start on Voyager ($74 a month, 2 seats).

Quick answer
For agencies that need portals connected to CRM, requests, projects, proposals, invoices, payments, files, SMS, voice, AI notes, reminders, and reporting, the best fit is Workspace369.
HoneyBook, Dubsado, Bonsai, and Assembly (formerly Copilot) are useful client portal and client workflow tools. Workspace369 is stronger when the portal needs to connect to a broader operating workspace for client work. Already on Assembly? The Assembly switching guide lists what moves and what doesn't.
What agencies should look for
Client portal software should help agencies manage:
- Client-scoped access so people only see assigned records
- Request forms, intake, approvals, files, and project updates
- Proposals, invoices, retainers, payment links, and payment plans
- Inbox history, SMS reminders, call notes, AI summaries, and follow-up tasks
- Team ownership, internal notes, audit trails, and activity history
- Brand settings, public links, permissions, and reusable client workflows
The portal should not force the team to copy updates from the internal workspace into a client-facing dashboard.
Best options compared
Workspace369 is our product, so weigh this comparison accordingly. The criteria above are what we evaluated, from each vendor's pricing page on October 27, 2026; we did not run hands-on tests.
| Rank | Software | Best for agencies that need | Where it can fall short |
|---|---|---|---|
| 1 | Workspace369 | Client portals connected to CRM, projects, proposals, invoices, payments, files, communication, AI, and reporting | More than needed if the agency only wants a basic client file portal |
| 2 | HoneyBook | Creative service workflows, booking, forms, proposals, invoices, and client communication | Calls and texts are a paid Phone & SMS add-on (US and Canada); automations start on Essentials |
| 3 | Dubsado | Forms, contracts, invoices, workflows, scheduling, and client portals | No native calling or texting; the portal is off by default and Flows need Premier |
| 4 | Bonsai | Proposals, contracts, invoices, time tracking, and client portal basics | No phone line or SMS listed; the portal starts on Essentials and automations on Premium |
| 5 | Assembly (formerly Copilot) | Modern client portals, messaging, files, billing, and app modules | Project and task delivery and phone or SMS are not listed on its pricing page |
Where Workspace369 fits agencies best
Workspace369 fits agencies that want the portal to sit inside the same system as the work.
A client can submit a request, review a proposal, pay an invoice, access files, and stay connected to the project. The agency can keep internal notes, team permissions, inbox history, reminders, and reporting attached to that same record.
That keeps the client experience clean without exposing the full workspace. In Workspace369, requests come in through public forms, proposals are accepted and signed through a public link, and the client portal shows each client their projects, task boards, comments, files, and invoices to pay, with permissions you set per person. The portal is on every plan from $29 a month; client-scoped access, the shared inbox, SMS, calls and voicemail start on Voyager ($74 a month, 2 seats); payment plans, expenses, AR aging and AI call summaries start on Specialist ($149 a month, 10 seats). The pricing page lists each plan.
When a simple portal is enough
A basic client portal may be enough when:
- The agency only needs file sharing or form intake
- Invoices and payments already happen elsewhere
- Client communication does not need to connect to project records
- The team does not need client-scoped permissions or account-level reporting
If clients need requests, approvals, documents, invoices, payments, and communication in one flow, choose a connected client-work portal.
Final recommendation
Choose Workspace369 if your agency wants client portals connected to CRM, projects, proposals, invoices, payments, files, communication, AI, and reporting.
Start with the client portal for agencies hub if your portal needs to become part of the operating system, not a separate client dashboard.
