Every agency that manages ongoing client work eventually gets asked the same question: 'Can we see the status of our project somewhere instead of emailing you?' That question is a client portal. It's become one of the most common builds agencies and freelancers ship on ViibeStack, because the core pieces — a login, a status view, and a shared file area — are things clients now expect, not luxury add-ons. The problem most builders run into isn't the build itself, it's pricing it. Charge too little and you're maintaining someone's infrastructure for free. Charge too much without justification and you lose the deal to a generic Notion share link. This piece breaks down what to actually charge, and why.
Strip it down to the essentials and a client portal has three moving parts: authentication (each client logs into their own account), a status view (where they are in the process, what's done, what's pending), and file sharing (uploads and downloads, ideally with version history). On ViibeStack, this is a realistic scope for a single-client-role app, built using the AI App Builder with a data model for projects, files, and users, plus a login screen. For this baseline, most freelancers charge a one-time setup fee between $1,500 and $3,500. Agencies with a productized process for this — meaning they've built it before and are mostly reusing patterns — often price closer to $2,500 to $5,000, since they're selling speed and reliability, not hourly effort.
The one-time setup fee covers the build: data model, login, status tracking, file uploads, basic branding. That's it. It does not cover the client adding a new project type six months later, wanting a second user role for their subcontractors, or asking why a file didn't upload. Those are ongoing costs, and they belong in a retainer, not folded into the setup fee. A workable structure: charge the setup fee to build and launch, then a monthly retainer of $150 to $500 for hosting coordination, small changes, and support. If you're the one on the hook when something breaks at 9pm before a client deadline, that has to be priced — it's not goodwill, it's an SLA. We wrote about this exact tradeoff in more detail in Pricing Your First ViibeStack Client App: Flat Fee vs. Retainer, and the short version holds here too: flat fees work for scoped, one-off builds; retainers work when you're the ongoing point of contact for something the client depends on daily.
A single-role portal — every client sees the same view — is the cheapest thing you can build. The price jumps the moment you add roles: an admin view for your team, a client-owner view, and a client-contributor view for people the client invites themselves. Each additional role means more permission logic, more testing of what each role can and can't see, and more edge cases when someone's access needs to change mid-project. If you're building this on ViibeStack, our role-based permissions guide is worth reading before you scope it, because permission structure is exactly the kind of thing that's cheap to plan up front and expensive to retrofit. As a rule of thumb: each additional role beyond the first two adds $500–$1,500 to the setup fee, depending on how different the permissions actually are.
A portal that only lives inside itself is simple. A portal that needs to pull invoice status from your billing tool, sync files to storage the client already uses, or trigger a notification in your team's helpdesk is a different job. Each integration is a point of failure you're now responsible for, and each one usually needs mapping, testing, and a plan for what happens when the external service is slow or down. Check the Integrations page for what connects natively before quoting a custom one — native integrations should barely affect price, since they're pre-built; anything requiring custom API work should add $300–$1,000 per integration to the setup fee, and often justifies bumping the retainer up a tier since integrations are the thing most likely to need attention later.
This one gets missed constantly. A portal for a consulting client with a dozen projects and a few dozen files is trivial. A portal for an agency's construction client uploading hundreds of large files per project, or a portal serving 200+ end clients simultaneously, is a different animal — you're now thinking about storage costs, upload reliability, search and filtering so the status view doesn't become an unusable list, and probably pagination and archiving logic. If a client's use case looks more like equipment tracking across dozens of records than a simple project list, price it like the more complex build it is. High data volume is a legitimate reason to add $1,000–$3,000 to setup and to insist on a higher retainer tier, because performance issues at scale are the kind of problem that shows up weeks after launch, not on day one.
Status tracking often isn't just a read-only progress bar — clients frequently want to approve deliverables from inside the portal, not over email. That's a meaningfully bigger feature than a status field, and it's worth pricing separately. We've covered the build tradeoffs in Client Approval Workflows in ViibeStack: Status Field or Approval Chain? — the short answer is that a simple status field is cheap, but a real approval chain with sign-off, comments, and revision requests is closer to a second feature than an enhancement, and should be quoted as one.
Start with a baseline setup fee for the core three features (login, status, files) at $1,500–$3,500. Add per-role pricing for anything beyond a basic client/admin split. Add per-integration pricing for anything not natively supported. Add a data-volume surcharge if the client's scale is genuinely bigger than a small project tracker. Then separate the retainer entirely — price it based on your actual support commitment, not as an afterthought. If you're pitching this to an agency client rather than building it for your own use, our Agencies page has more on positioning recurring work like this as infrastructure rather than a one-off project, which is usually the framing that makes clients comfortable paying a retainer in the first place.
