- A client portal should replace the emails your team sends most often: status updates, documents, invoices and requests.
- Access control is the heart of a portal: every client must see only their own records, tested deliberately.
- Start with documents, requests, invoices and notifications; leave chat, social features and complex dashboards for later.
- An audit log and clear notifications build trust with clients and protect your team when questions come up.
What should a client portal include?
A client portal should include secure login with clear roles, a document area, a way to raise and track requests, invoices and payments, notifications and an audit log, all showing each client only their own information. Its job is to replace the status emails, attachments and "can you resend that?" messages your team handles every week. Everything else is optional, and much of it is better left for a second version.
This is the checklist we use when we plan a portal as part of our custom software development work.
How should roles and permissions work?
Access control is the most important part of any portal. A client must never see another client's files, invoices or messages, and that has to hold for every page and every API request, not only in the menus.
- Client organisations with several users each, such as a finance contact and a project contact.
- Roles inside each client, for example admin, member and view-only, so the client controls who sees invoices.
- Staff roles on your side, limited to the clients each person works with.
- Tests that try to break it: logging in as one client and requesting another client's documents by changing an ID in the address bar.
What should the document area do?
- Folders per client and per project, with clear names and dates.
- Upload by both sides, with file type and size checks and malware scanning where documents are sensitive.
- Version history, so a new contract does not silently replace the signed one.
- Secure download links that expire, rather than files sitting on a public URL.
- Optional approvals or e-signatures for documents that need sign-off.
How should requests and tickets work?
A simple request system cuts email more than any other feature. Let clients raise a request with a category, a description and attachments, see its status, and reply in one thread. Your team gets a queue with owners and due dates. Keep the workflow short: new, in progress, waiting on client, done. If your team already uses a help desk or project tool, connect the portal to it instead of building a second one.
Should the portal show invoices and payments?
Yes, if billing questions take up your team's time. Show open and paid invoices, statements and receipts, ideally pulled from your accounting system so there is one source of truth. Online payment through a provider such as Stripe lets clients pay in a few clicks, with the status updating automatically. The payment provider handles card details, so the portal never stores card numbers.
What notifications do clients actually want?
- A new document or invoice is ready.
- A request changed status or got a reply.
- Something needs their action, such as an approval or a missing document.
Send them by email with a link back into the portal, let clients choose how often they hear from you, and avoid notifying people about every small change. Too many emails train clients to ignore them.
Why does an audit log matter?
An audit log records who did what and when: who uploaded or downloaded a document, who approved it, who changed a setting. It answers questions quickly when a client says they never received something, it supports compliance in regulated industries, and it protects your team. Keep it read-only and include it from the first version; adding it later means the early history is missing.
How should people log in?
For most portals, email and password with two-factor authentication or passwordless magic links are enough. Larger business clients may ask for single sign-on with their own identity provider. Add session timeouts, rate limits on login attempts and a self-service way to reset access, so your team is not the password help desk.
What should you leave out of the first version?
- Live chat: request threads cover most needs without staffing a chat window.
- Complex dashboards before you know which numbers clients actually look at.
- Social features such as comments on everything or activity feeds.
- Every integration at once. Start with the one or two systems that hold the data clients ask about most.
- A native mobile app, unless clients truly need it; a responsive web portal works on phones.
How should a portal be built?
A portal is a web application with a strong back end. We usually build the back end with Laravel or Node.js and the interface with React or Next.js, hosted in the client's own cloud account. Plan it like any product: map the top five reasons clients contact you today, design the portal around those, and launch to a few friendly clients first. Our guide to planning an MVP describes how to keep that first version small.
Frequently asked questions
Should we build a client portal or use an off-the-shelf tool?
Use an off-the-shelf portal when your needs are standard: sharing files, sending invoices and collecting forms. Build one when the portal must show data from your own systems, follow your specific workflow or carry your brand fully, or when per-client licence fees would grow faster than the value it brings.
How do clients log in securely?
Email and password with two-factor authentication, or magic links sent by email, work for most portals. Business clients may prefer single sign-on through their own identity provider. Whichever you choose, add rate limiting, session timeouts and a simple way for clients to reset access without calling your team.
Can a portal take payments?
Yes. A portal can show invoices and let clients pay by card or bank transfer through a payment provider such as Stripe, with the payment status updating automatically. The provider handles the card details, so your portal never stores card numbers itself.
How long does a client portal take to build?
A focused first version covering login, documents, requests and invoices usually takes a few months, depending on how many systems it connects to. Integrations with your existing CRM, accounting or project tools are often the biggest part of the work, so list them early.
