Engagements - Build a client portal your customers log in to — dashboard, files, and billing
Your clients live in your inbox: chasing status, re-sending files, asking where the invoice went, waiting on an update only you can give. It doesn't scale, and it doesn't look like the software company you're trying to be. A client portal build gives each customer a real login and a dashboard of their own — their projects, their documents, their messages, their invoices — built by one senior engineer over a focused stretch of weeks, not a stack of half-finished tickets. This is client portal development as a whole outcome, not a plugin bolted onto your marketing site.

What you'll have at launch
A live customer portal your clients log into: a client dashboard, files and messages, role-based access, and billing — replacing the email-and-spreadsheet handoff.
- A secure client login where each customer sees only their own account — a customer portal with real auth, password reset, and per-client data isolation, not a shared password.
- A client dashboard showing project status, deliverables, and the numbers each client actually asks you for, loading in under a second.
- File and message workflows: clients upload and download documents, leave comments, and get notified — so approvals and hand-offs stop living in email threads.
- Billing built in — invoices, subscriptions, or one-off payments through Stripe — so clients pay from the portal instead of chasing a link.
How we build it
A build runs 4–8 weeks typical, shipped week by week in increments you review and merge.
Weeks 1–2 · Accounts, roles & access
We model your clients, their teams, and who's allowed to see what, then build the auth and role-based access on top: a client admin, their team members, and your internal staff each get the right view. Getting per-client data isolation right up front is what keeps a customer portal trustworthy — no client ever glimpses another's data.
Weeks 3–5 · The client dashboard & workflows
The client dashboard, document workflows, and messaging get built in weekly increments you review and merge — the screens your customers live in and the actions they take most. We start with whatever hand-off hurts most today, so you're retiring an email thread by week three, not at the end.
Weeks 6–8 · Billing, notifications & launch
Stripe billing, invoices, and the notification emails go in; empty states and onboarding get real so a new client can self-serve on day one; and we run a launch pass — access-control checks, error handling, a staging run — before flipping the portal live.
What's included
- A customer-facing client portal with its own authentication — sign-up or invite, login, password reset, email verification — scoped so each client only ever sees their own data.
- A role-based client dashboard: project and order status, deliverables, and reports on your live data, with separate views for client admins, their team, and your internal staff.
- Document and file workflows — upload, download, versioning, and approvals — plus in-portal messaging or comments so hand-offs leave the inbox.
- Billing wired to Stripe: invoices, subscriptions, or one-off payments from inside the portal, with the customer billing portal for self-serve plan changes.
- Lifecycle notification emails — new message, status change, document ready, invoice due — so nothing needs chasing by hand.
- An internal admin side to manage clients, invites, and access, plus deploy and handoff into your repo and cloud account so the portal is yours to run.

How it runs on the subscription
A client portal is weeks of connected work — auth, a client dashboard, file and billing workflows — not a single task, so it runs as a build: the board dedicated to your portal, shipping usable pieces every week. Same flat monthly subscription, from $6,900/month, most client portals landing in four to eight weeks. You retire the worst manual hand-off first and reprioritize as real client feedback lands; pause between phases whenever, and after launch the same subscription flips to task mode for the steady trickle of new views and fields a live portal generates.
Frequently asked questions
- What's the difference between a client portal and an internal admin platform?
- A client portal is customer-facing first: your clients log in to a dashboard of their own to see status, exchange files, message you, and pay invoices. An internal tools platform is staff-facing first — the admin console your team runs the business from. This build centers the client experience, though it includes the internal admin side needed to manage accounts and access. If you mainly need the staff-side console, the internal tools & admin platform build is the closer fit.
- Can each client only see their own data?
- Yes, and that's the part we build carefully first. Each customer's data is isolated behind their own login and role, so one client can never see another's projects, files, or invoices. Getting this access model right up front is exactly what makes a customer portal safe to put in front of real clients — it's the piece that's easy to get subtly wrong.
- Can clients pay invoices or manage a subscription in the portal?
- Yes. Billing is wired to Stripe inside the portal — invoices, subscriptions, or one-off payments, plus the customer billing portal for self-serve plan changes and cancellations. Clients pay from their dashboard instead of hunting for a payment link in an old email, and you stop chasing.
- How long does a client portal take to build?
- Most client portals land in four to eight weeks, depending on how many workflows they carry — a status-and-documents portal is faster than one with billing, messaging, and multi-role teams. It runs on the flat monthly subscription, from $6,900/month, so you pay for the active weeks rather than a fixed project total, and can pause between phases.
- What do we own at the end?
- Everything. It's a standard Next.js and PostgreSQL app in your repo, deployed to your cloud account, with a walkthrough of how it runs. After launch the same subscription flips to task mode for the steady stream of additions a live portal generates — a new report, an extra client view, another notification — one at a time on your board.
