The best client portal for an agency is the one that gives clients a single place to send requests and approve work, not only a folder for files. Agencies selling retainers or set packages often need a request queue with proofing, while agencies running bigger projects may get more from a project suite with a client-facing side.
A typical week with one agency client goes like this. They email a brief, add a change by text message, approve the homepage on a call and ask about an invoice in reply to a thread from three weeks ago. Your team spends hours piecing that together, and the client still isn't sure what's been signed off.
This list is for marketing, design and web agency owners who want clients to send requests, approve work, share files and pay in one branded place. Four of the eight are built for agencies or name agencies on their own pages, and I've said so. The other four are general tools many agencies use with clients, labelled honestly. The eight sit in no particular order, grouped by what each portal is built around.
Four ways agency portals are built
Request portals built for agencies
ManyRequests is the clearest agency match here: its own page calls it the white-labeled client portal for agencies and productized services, with requests, proofing, time tracking, subscriptions and invoicing under your own brand. Content Snare is narrower and lists digital agencies as a use case. It's built for collecting content, information and documents from clients, such as onboarding questionnaires, website content and marketing asset requests, with a portal for files.
PSA suites with a client-facing side
PSA stands for professional services automation: software that runs your projects, your people and the money side of client work. These two aren't pure portals, and it's worth knowing that before a demo. Teamwork calls itself a PSA platform for managing projects, resources and capacity, and its page lists client intake forms. Accelo connects projects, resources, financials and forecasting for professional services firms, and lists a Client Workspace under client management. Both suit agencies that run on projects and timesheets, and both give clients a view in rather than a full portal.
All-in-one client portals
These are general portal tools used by many kinds of service business, agencies among them. SuiteDash lets you design your own white label portal with secure login, a branded dashboard and email notifications. Assembly combines a CRM with a branded client experience where clients onboard, sign, collaborate and pay, and its page lists marketing agencies among its industries. Moxo is a workflow automation platform that gives each customer or partner a branded portal to take action in, so it leans towards step-by-step processes. For the wider field beyond agencies, see our guide to client portal software for service businesses.
Project tools clients can join
Basecamp is a general project tool, not a portal. Its page describes managing projects and working with clients in one place, which is enough for agencies whose clients mostly need to see progress and reply in one thread. If that's your situation, our list of project management tools for creative agencies covers more of this side.
Eight agency portals side by side
| Tool | Built around | Good for an agency that wants |
|---|---|---|
| Accelo | PSA suite with client workspace | Running projects and finances with a client view |
| Assembly | CRM and branded client portal (general) | Onboarding, signing and payment in one portal |
| Basecamp | Project tool clients can join (general) | Clients following progress in shared projects |
| Content Snare | Client content collection (names agencies) | Gathering content and documents from clients |
| ManyRequests | Request portal (built for agencies) | Requests and proofing for retainers and packages |
| Moxo | Workflow portals (general) | Step-by-step client processes |
| SuiteDash | All-in-one white label portal (general) | A fully branded portal with secure login |
| Teamwork | PSA suite with client intake | Project-led agencies tracking capacity |
Requests and sign-off matter more than branding
Most agencies choose a portal for file sharing and a logo on the login screen. Then they find the friction was never the files. It's request intake and approvals: a client emails a brief, asks for edits in three different places, and nobody can say with confidence which version was signed off.
Before you compare branding options, check two things. First, does the tool give you a single request queue, so every ask lands in one place with an owner? Second, does it have proofing, so the client can comment on and approve the work itself rather than replying 'looks good' to an email?
Then look at the client's side. Every portal adds a login, and clients already juggle plenty. Ask how a client gets in, whether they can act from an email notification, and what they see on the first screen. A request portal built for agencies and a PSA suite solve different halves of this problem: the first is built around the client's ask and approval, the second around your team's projects, time and margins. Few agencies need both on day one, so decide which half hurts more.

Questions to put to every vendor on a demo call
A demo account always looks tidy. These questions show how the portal behaves once real clients are in it.
- Can clients send a request without yet another login? Ask to see the request step from the client's side, including from an email link.
- Where do approvals live? Ask how a client signs off a design or a page, and whether that sign-off is recorded against the work.
- Whose brand does the client see? Check the portal, your own domain and the notification emails, not just the dashboard.
- How does a request reach your team? If someone copies it into a task list by hand, it will be missed on a busy week.
- How are invoices handled? Inside the portal or through a separate tool? Our guide to cutting invoicing and admin time in a marketing agency covers that part.
- What about client data? If you store personal data for clients, rules vary by country, so check the regulator's guidance where your clients are.
My advice, depending on how your agency sells
If you sell set packages, retainers or a productized service, start with a request portal built for agencies. Your clients' main job is to ask for work and approve it, and a request queue with proofing handles exactly that. Add a tool for collecting content only if onboarding is where you lose time; our list of client onboarding tools covers that stage in more depth.
If you run bigger projects with timesheets, resourcing and margins to watch, a PSA suite with a client-facing side will do more for the business, even if the client view is simpler than a dedicated portal. If you're a small studio whose clients mostly need to see progress and reply in one place, a general project tool may be all you need for now.
Whatever you shortlist, read the free plan or trial terms on the vendor's own site; several here state one as of Nov 2026. Then invite one friendly client in before you roll it out to everyone. Ask them to send a request and approve something. If they need help to do either, the rest of your clients will too.

Frequently asked questions
What should an agency client portal include?
At minimum, a single place for client requests, file sharing and approvals. Many agencies also want invoicing in the same portal, and branding on their own domain so clients see the agency rather than the software.
Is a PSA the same as a client portal?
No. A PSA runs your agency's projects, people and finances, and some include a client-facing workspace. A dedicated client portal is built around the client's side: requests, approvals and files.
Can I use a project management tool as a client portal?
Yes, if clients mostly need to see progress and reply in one place. It's usually thinner on request intake, proofing and branding than a portal built for agencies, so check those if they matter to you.
Do clients mind using a portal?
Clients mind extra logins and confusing screens. Pick a tool where a client can act from an email notification or reach the request form quickly, and walk your first clients through it once.
Should a small agency white label its client portal?
It helps clients trust that they're in the right place, and it keeps your brand in front of them. It matters less than the request queue and approvals, so check those first and branding second.
How do I move existing clients onto a new portal?
Start with new projects or one friendly client rather than moving everyone at once. Keep the old channel open for a short while, and point every new request to the portal until it becomes the habit.
