Services · Ecommerce development · AI document processing subscription sites
Codeeo provides AI document processing subscription website development London startups and scale ups use to turn a working product into a business that bills itself. We build the pricing pages, self serve sign up, metered billing, multi currency invoicing and customer account area, and we connect them to your extraction or review engine through its API. London buyers range from a five person fintech in Shoreditch to a compliance team at a Canary Wharf bank, so the site has to sell to both without two separate systems.
We do not build your models. We build the commercial platform that sits in front of them: where a prospect decides, pays and returns to manage seats, usage and invoices. Done properly, it lets a small London team sell to customers in several countries without hiring a billing department. Every sale is recorded once and flows to your CRM and accounts.

What the platform includes
A London document AI company usually sells in two ways at once. Smaller teams find you through search or a product launch, try the product on their own documents and pay by card. Larger buyers in the City arrive through a referral, send a security questionnaire and want a contract with their name on it. The website has to carry both. The capabilities below are the ones we most often build for London clients, chosen because each removes a step that would otherwise need a salesperson, an accountant or an engineer. They connect to your product, your CRM and your accounting software so that a sale made on a Tuesday night in another time zone is billed, provisioned and recorded correctly without anyone at your end touching it.
Plans priced in pounds, euros and dollars, with the right currency shown from the buyer's location and a manual switch for those who invoice elsewhere. Each currency keeps its own price points rather than converting at a daily rate. Annual prices show the monthly equivalent, so buyers comparing plans see like for like.
Overseas buyers see a price they can approve without doing sums.
A base fee for seats plus a monthly page or document allowance, with overage metered from your product's usage events. Customers see consumption by workspace, so a law firm can tell which practice group used the allowance.
Invoices that match what each team actually processed.
SAML or OpenID Connect sign in through the buyer's identity provider on higher plans, with automatic removal of leavers. Most London enterprise buyers ask for this in the first security call.
Enterprise IT teams approve the purchase sooner.
A gated area where buyers request your data processing agreement, penetration test summary, sub-processor list and hosting details. FCA regulated customers run supplier due diligence before outsourcing any processing, and this page shortens it. Downloads are logged so your sales team knows which prospects are close to buying.
Fewer weeks lost between a verbal yes and a signature.
Enterprise customers move from a quote to an e-signed order form and an invoiced subscription with purchase order numbers and payment terms, recorded in the same billing system as card customers.
Annual contracts and self serve plans live in one place.
Card payment that authenticates once when the subscription starts, then charges renewals and overage as merchant initiated transactions. Wallets sit alongside cards for founders buying on a phone between meetings.
Fewer declined renewals from unnecessary challenges.
VAT numbers captured and validated, UK VAT on UK invoices, and overseas customers handled according to whether they are businesses or consumers and where they sit. US sales tax can be calculated by your billing provider where it applies.
Cross border invoices your accountant does not need to correct.
Customers upgrade with proration calculated on screen, schedule a downgrade for the next period, pause a workspace or cancel, all without emailing support. Every change triggers a confirmation email and an updated invoice preview.
Account changes stop queuing in your support inbox.
Monthly recurring revenue, net revenue retention, churn by plan and currency, and payment failure rates, drawn straight from the billing system into a dashboard and an export for your data room. Figures update daily and reconcile with Xero or your ledger.
Board and fundraising numbers taken from one source.
A sign up path for engineers who want to call your extraction API directly, with key management, usage logs, rate limits by plan and documentation pages that sit inside the same site.
Developers can start building on the same day they register.
Who this is for
Many London document AI companies work from around Old Street, King's Cross and the fintech community at Canary Wharf, and their customers are often a few streets away in the City or across the Atlantic. Each of the situations below changes what goes into the first release, so we start by working out which one describes you and which buyers bring in most of your revenue today.
You have early customers on hand written invoices and want new ones to sign up and pay without a call. We put public plans, checkout and an account area live, migrate the first customers onto matching plans and set up the onboarding emails that get a new user to their first processed document. Help articles and an in app checklist cover the common first questions, so your small team is not answering the same email every morning.
Early adopters can keep their original prices.
Contract analysis and disclosure tools sell to firms that expect confidentiality wording, UK hosting, matter level usage reports and a signed agreement. Self serve still helps for smaller practices and in house teams. We build the gated security pack and the enterprise contract route alongside the public plans. Matter codes can be attached to uploads so firms can recharge usage to their own clients, which partners in London often ask about before signing.
KYC file review, bank statement analysis and onboarding checks are bought by firms the FCA supervises. They want audit logs, data location statements and clear terms on how documents are retained. The site publishes all of this and supports annual invoiced contracts with defined usage bands. Usage bands are visible to the customer's own finance team, so a quarter end surge does not turn into a surprise invoice and a difficult renewal conversation.
When half your pipeline is overseas, a pounds only price list loses deals. We add local currency plans, tax handling by country, US English copy where it helps, and a sub-processor page that explains how data moves under the UK data bridge with the US. Copy on the plan pages is adjusted per market, so an American buyer and a London buyer both read terms that sound familiar.
We keep one billing system rather than one per region.
How we work together
We have no London office; our team works with London clients remotely, and every workshop, review and handover runs by video call. Most clients begin with a fixed scope build, then move to a retainer for pricing tests, new plans and integrations. Some fund a dedicated team for a longer programme of AI document processing SaaS website development. Cost is shaped by the number of currencies, the complexity of usage billing, enterprise contract handling, SSO and how much customer data must be migrated. Ongoing hosting, monitoring and billing support are available after launch, priced separately and optional.
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
Pricing and account pages are usually built in Next.js for speed, with Stripe or Chargebee for billing and HubSpot or Salesforce receiving every sign up. We pick tools your engineers can maintain after we hand over. Hosting can sit in UK or EU regions when your customers' contracts require it.

It depends on your billing model, not the number of pages.
A site with fixed plans in one currency moves much faster than one with seats, metered pages, three currencies, SSO and enterprise contracts. Migrating existing customers adds time as well. We agree the timeline in discovery once these points are settled, write it into the scope, and report progress against it at each video review. If a funding round or a product launch fixes your date, tell us at the start and we will shape the first release around it.
