Services · Ecommerce development · AI document processing subscription sites
Codeeo handles AI document processing subscription website development UK software companies use to sell their product online: pricing pages, sign up, recurring billing, VAT invoices, plan changes and a customer account area, all on your own domain. If you sell extraction, classification or document review as a service, the website is where a buyer compares plans, enters card or Direct Debit details and comes back to raise their page allowance. We build that commercial layer so it follows UK consumer, payment and data rules.
The document AI itself is your product. Our work is the storefront and billing platform around it: what customers see before they pay, what happens at each renewal, and what your finance team sees afterwards. It connects to your product through its API so usage, plan limits and access rights stay in step, and nobody keeps processing documents on a plan that lapsed weeks ago.

What the subscription site includes
A buyer of document AI usually arrives with one question: how many documents can I process, and what does that cost each month? The site has to answer that clearly, take payment in a way UK finance teams accept, and then keep billing accurate as usage rises and falls. Since April 2025 the Digital Markets, Competition and Consumers Act 2024 has treated hidden or dripped charges as unfair, so mandatory fees belong in the headline price. The separate subscription contract rules in the same Act are still waiting on secondary legislation, and we design the renewal and cancellation flows so they can meet those rules when they commence. Below is what we typically put in the first release, ordered the way a customer meets it.
Plans described in units buyers recognise, such as pages, documents or API calls per month, with overage rates explained in words and VAT shown as included or excluded depending on who the plan is for. Comparison tables stay readable on a phone and work with a screen reader.
Buyers can choose a plan without booking a call first.
Card checkout with Strong Customer Authentication on the first payment, so later renewals can run as merchant initiated charges, plus Bacs Direct Debit for customers whose accounts teams prefer it. Apple Pay and Google Pay can sit alongside for smaller buyers.
Fewer failed first payments and fewer abandoned sign ups.
Your product reports processed pages to the billing system, customers see a live allowance bar, and they can buy a top up or move to a larger plan before a busy month rather than after an unexpected bill.
Usage charges customers expect instead of ones they dispute.
Invoices carry the details HMRC expects on a VAT invoice, VAT numbers are captured and checked at sign up, and buyers outside the UK are treated according to whether they are a business and where they are based.
Invoices finance teams can file without asking for a reissue.
Customers add seats, change plan, update payment details, download invoices and manage API keys themselves. Upgrades are prorated on the spot; downgrades take effect at the next renewal with the date stated on screen.
Your support team stops processing routine plan changes by hand.
Reminders before annual renewals, a cancellation route as simple as sign up, and clear confirmation emails. For consumer or sole trader customers we can add the cooling off notices the Consumer Contracts Regulations require.
Renewals that hold up if a customer or regulator questions them.
Retry schedules, card updater support, polite reminder emails and a grace period before processing is paused, all configurable so you decide how long a lapsed account keeps access to its documents.
Revenue recovered without your team chasing every decline.
A public page holding your data processing agreement, sub-processor list, hosting location and retention policy. Because customers upload contracts and identity documents, buyers will ask for these before they pay.
Security reviews move faster because the answers are already published.
Larger customers rarely pay by card. A request route collects company details, expected volumes and procurement contacts, then your team issues an order form and an invoiced plan that still lives in the same billing system, with the same allowance bar and renewal dates as self serve accounts. Purchase order numbers print on every invoice.
Enterprise deals and card sign ups report as one revenue line.
Recurring revenue, churn, expansion and failed payment figures pulled from billing into one dashboard, with exports your accountant can reconcile against the ledger.
Monthly numbers come from one source rather than a spreadsheet.
Who this is for
Selling document AI across the UK means selling to buyers with very different expectations. A two partner accountancy practice in Swansea wants a card and a monthly plan; a housing association in Glasgow wants a purchase order and a written contract. The site has to handle both without forcing either through the wrong route. These are the four starting points we see most, and each one changes which features belong in the first release.
Many document AI products start with a handful of customers billed by bank transfer. When growth depends on buyers signing up without a sales call, you need public plans, automatic billing and an account area. We build that first release around your current customers so none of them lose access or get billed twice during the switch. Pricing copy, onboarding emails and the help centre are written at the same time, so new buyers understand the product without a demo.
We migrate existing customers onto the new plans before opening sign up.
Receipt, invoice and bank statement extraction sells to practices whose workload peaks around the January Self Assessment deadline and quarter ends. Plans with seasonal top ups, practice level accounts with several client workspaces, and Direct Debit billing suit how these firms buy software. Partners often want to see what each client file costs them, so usage reports can be split by workspace for onward billing.
Contract review and due diligence products sell to law firms in England and Wales, Scotland and Northern Ireland, each with its own legal system. Buyers expect strict confidentiality wording, UK hosting options and the ability to sign an order form rather than click through terms. We build the site so both routes exist, with matter level usage reports that firms can recharge to their own clients.
Councils, NHS bodies and housing providers usually buy through procurement frameworks and pay on invoice. The site still matters: it carries the documentation buyers check, and it handles the smaller teams who can pay by card. We keep both routes on one billing record, and accessibility statements are published because public sector buyers will check for them.
Card buyers and invoiced buyers end up in the same reporting.
How we work together
Most of our UK work is AI document processing SaaS website development for companies that already have a working product. The team works with UK clients remotely, with discovery sessions, design reviews and sign off held by video call. Most companies start with a fixed scope first release covering pricing pages, checkout, billing and the account area. After launch, a monthly retainer covers new plans, pricing experiments and integration changes. Companies with a larger roadmap sometimes take a dedicated team from our Dubai, Riyadh and Karachi offices. Cost depends on the number of plans and billing rules, the integrations involved and how much existing customer data needs migrating. For teams that only need AI document processing billing integration services UK wide, we can connect billing to an existing site without rebuilding it.
A defined build with a deadline
We agree what the product has to do, write it down with a price and a date, and build exactly that. Changes are priced before they are made, not discovered on the invoice.
A product that keeps evolving
Named engineers who work your hours, join your standups and stay on the codebase. You direct the backlog; we own the quality of what ships.
Something live that needs looking after
A monthly block of hours for improvements, fixes and the small requests that otherwise wait months. Unused hours carry for a quarter.
Technology
We usually build the site in Next.js or WordPress, depending on who edits the content, with Stripe, Chargebee or GoCardless handling billing. The choice follows your product's API, your accounting software and your team's skills. Hosting can sit in UK data centres where buyers ask for it, and every integration is documented for whoever maintains it next.

It depends on billing complexity more than page count.
Metered usage, several currencies, seat based pricing, migration of existing customers and integrations with your CRM and accounting system all add work. A simple site with three fixed plans costs far less than a platform with usage billing, enterprise invoicing and a trust centre. We price after discovery, once these choices are written down, so the quote reflects your real billing model. Timing follows the same logic: billing rules and migration drive it more than design.
