Customer Portal Development UK

What a customer portal does for you

A customer portal is a private area of your website where each customer logs in and sees their own information. It answers the questions your staff are asked every day: has my order shipped, can you resend that invoice, where is the certificate for that job, what do I owe? When customers can answer those themselves at 10pm, your inbox shrinks and your service looks better.

Portals also open up self-service actions. Trade customers can reorder their usual lines, approve quotes, book collections, log support tickets or upload purchase orders. Each action lands in your system as structured data rather than an email someone has to retype.

There is a commercial upside too. A trade customer who can check stock and reorder in two minutes at any hour is less likely to try a competitor. A service customer who can download every gas safety or electrical certificate for their sites in one place sees you as easier to work with at contract renewal. For many firms the portal becomes part of the sales pitch.

Common portal types we build

• Trade and B2B ordering portals for wholesalers and manufacturers, with customer-specific price lists, minimum order quantities, credit limits and repeat ordering.
• Service and job portals for field service, facilities and construction firms, showing job status, engineer reports, photos and compliance certificates.
• Billing portals where customers view invoices and statements and pay by card, especially useful alongside automated billing software.
• Client document portals for professional services firms who need a safer alternative to email attachments.
• Supplier portals, the same idea pointed the other way, where suppliers confirm orders, upload delivery notes and check remittances.

Where the data comes from

The value of a portal depends on the data being right. We look at where each piece of information lives today and choose the safest way to show it:

• Accounting data such as invoices, credit notes and balances is usually read from the Xero API, QuickBooks Online API or Sage, either live or synced on a schedule and on webhook events. See accounting software integration.
• Order and stock data may come from your ecommerce platform, an ERP or a bespoke stock system.
• Job data often comes from a field service app or your own job management software.

Where the source system has strict API rate limits, we keep a local copy in the portal's database and refresh it in the background, so customers get fast pages and the source system is not overloaded. Every sync is logged so mismatches can be traced.

Security and access

A portal puts your data on the internet, so access control matters more than anything else. Every request is checked against the logged-in user's customer account, and we write automated tests that try to open another customer's invoice and must be refused. Customers can have several users with different rights: an accounts contact who sees invoices, a buyer who can order, a site manager who only sees their site.

We add two-factor authentication or Microsoft and Google sign-in for larger customers, rate-limited logins, expiring download links and a log of who viewed or downloaded each document. That log is useful when a customer says they never received an invoice.

Planning a portal: the questions we ask

Good portals start with a short list of what customers ask for most. Before scoping, we usually ask you to look back at a month of emails and calls and tally the requests. The top five become the first release. We also ask:

• Which system is the source of truth for each type of data, and how current must the portal be?
• Who at each customer should see what, and who manages their users: you or them?
• Which documents can be generated on the fly, and which are uploaded by staff?
• Should the portal live on your own subdomain, and does it need to match an existing website design?

The answers shape the data model and the fixed-price quote.

Payments, notifications and launch

If customers can pay outstanding invoices by card in the portal, cash comes in faster. We use Stripe Payment Intents, mark the invoice as paid in your accounting package automatically, and send a receipt. Notifications by email or SMS tell customers when something changes, such as an order dispatched, a job completed or a new document uploaded.

We usually launch with a pilot group of friendly customers, fix what they find confusing, then invite everyone. The portal is part of the wider family of web applications we build, and often sits alongside a custom CRM. Start with a free chat and we will scope it and give a fixed-price quote.

How it works and what it costs

Every project gets a fixed-price quote after a free initial chat and a short scoping stage. You own the code and the data.

1. Free chat

   Tell us the problem in plain English: what you do now, what goes wrong and what "better" looks like. No charge, no obligation.

2. Scoping

   We map the processes, systems and data involved, agree what is in and out, and write it down so there are no surprises.

3. Fixed-price quote

   You get a fixed price for the agreed scope, or a phased plan for bigger builds, so you can start small and prove it works.

4. Build and test

   We build in short stages you can see and try, test against real data, then go live carefully with a rollback plan.

5. Hand over and look after

   You own the code and the data. We can host it, support it and keep improving it, or hand it to your own team.
