Before you brief a developer on a customer portal, answer these six questions
A practical checklist covering access, data, security and support for customer portal development.
The short answer
Customer portal development means building a secure, logged-in area where customers can view orders, documents or account status without emailing or calling you. Before briefing a developer, decide who logs in, what they can see or change, how accounts are verified, and who supports the portal once it's live.

What should a customer portal actually do?
Start from the task, not the feature list. Common uses include viewing order or job status, downloading invoices and documents, submitting requests, or booking appointments. A portal that just repeats your brochure website in a login screen isn't worth building.
Checklist before you brief a developer
- Who are the users, and do different users see different information?
- What data will the portal show, and where does it live today (spreadsheet, CRM, invoicing tool)?
- How will customers prove who they are: email link, password, or an invite code?
- What happens if a customer forgets their password or leaves the business?
- Does the portal need to write data back into another system, or just display it?
- Who fixes a bug or answers a customer's access query after launch?
Read-only status portal
- — Shows order or job status
- — Cheaper to build
Portal with payments and write-back
- — Takes payments
- — Writes into your job system
- — Costs far more
Security and data protection basics
A customer portal holds personal data, so it falls under UK GDPR. Make sure each customer can only see their own records, passwords are stored securely (never in plain text), and you have a process for data access or deletion requests.
The NCSC's guidance on securing customer-facing systems is a sensible starting point for the technical conversation with any developer.
“Define exactly what each customer can see and change before design starts.”
A realistic build sequence
| Stage | What happens |
|---|---|
| Discovery | Map who logs in and what they need to do |
| Design | Wireframe the key screens and login flow |
| Build | Develop login, data display and any write-back features |
| Testing | Check permissions: can one customer ever see another's data? |
| Launch and support | Hosting, monitoring, and a plan for bug fixes |
What customer portal development costs
A simple read-only portal (view status, download a document) is far cheaper than one that takes payments or writes back into your job system. Ask for a scoped quote against a written brief rather than a single headline number.
Maintaining a portal after launch
A customer portal is never really finished. Plan for security updates, occasional bug fixes, and small improvements once real customers start using it. Agree upfront who is responsible for monitoring uptime and responding if customers report access problems.
Fixby's hosting and maintenance plans cover this kind of ongoing care for simpler sites; a portal with login and personal data typically needs a dedicated support arrangement.

Your questions
- What is customer portal development?
- It's building a secure, logged-in area of a website where customers view or manage their own information, such as orders, invoices or bookings, instead of emailing or calling your business.
- How much does a customer portal cost?
- Costs vary widely depending on features. A basic read-only status portal costs far less than one that integrates with your invoicing or job management system. Get a quote against a written brief.
- Is a customer portal GDPR compliant by default?
- No. You need to build in access controls, secure authentication and a way to handle data requests. Compliance depends on how it's built and run, not the idea itself.
- Do I need a portal or would email updates work?
- If customers regularly ask the same status questions, a portal can reduce that load. If requests are rare, automated email updates may be cheaper and simpler.
