Services · Ecommerce development · Billing software subscription sites
Codeeo offers subscription billing subscription website development London vendors of recurring billing, invoicing and revenue software use to win customers at both ends of the market. A two person startup picks a plan and pays by card in minutes. A procurement team at a Canary Wharf firm finds your security pack, data processing terms and an enterprise route to a salesperson. Both sit on one site, and both end up in the same billing record.
London vendors sell across time zones and currencies from the first month, so the site handles more than sterling and UK VAT. We work with London clients remotely, running discovery, reviews and testing by video call, from a team of 80+ across Dubai, Riyadh and Karachi rated 4.7 from 23 Google reviews.

What the site includes
Billing software companies in London tend to sell in two directions at once. Founders around Old Street, Shoreditch and Clerkenwell want to start today without a call. Finance and procurement teams in the City, Canary Wharf and the corporate offices around King's Cross want evidence before they sign anything: security answers, contract terms, references to standards and a named contact.
A site built only for the first group loses the large deals, and a site built only for the second makes small customers wait for a demo they never wanted. We design the pricing page, the checkout and the account area so each buyer type finds its own route quickly, and we connect every route to your billing engine so finance sees one customer list, whichever door the customer came through. Many London customers pay in euros or dollars, so currency and tax logic is part of the first release, not a later project, and the London entity details appear on every invoice.
Published plans for smaller customers, with seats, invoice volumes or revenue bands shown plainly, and an enterprise tier that explains what changes: contract terms, invoicing by purchase order, single sign-on and support levels. The enterprise button opens a short qualifying form that routes to the right salesperson instead of a generic inbox.
Small buyers start alone and large buyers reach a person quickly.
Prices set deliberately in sterling, euros and dollars, card payment with Strong Customer Authentication at sign-up, and wallet payments where your provider supports them. Customers keep the currency they started in, and invoices match what they saw on the pricing page, which matters to finance buyers who check every line.
International customers pay in their own currency without surprises.
A section that gathers your security practices, sub-processor list, data residency options, uptime history and a request route for the data processing agreement and penetration test summary. Procurement teams in the City often send a questionnaire; this answers most of it before they ask, and records who requested what.
Security reviews start with answers already on the table.
Company accounts with several admins, roles for finance and IT, seat management and single sign-on through the identity provider the customer already uses. Invoices can go to an accounts payable address rather than the person who signed up, which is how larger London firms prefer to receive them.
Larger customers manage access without raising tickets.
UK VAT for domestic customers, VAT number capture and reverse charge wording for overseas businesses, and sales tax handling for US customers through your tax provider where you have obligations there. Invoices show the legal entity, addresses and tax details each jurisdiction expects, ready for the customer's own reconciliation.
Tax on every invoice stands up to a finance buyer's review.
Customers change plans or seat counts from their account. The site previews the prorated charge or credit before they confirm, and your rules decide whether reductions apply now or at renewal. Annual customers adding seats mid-term get a clear co-termed invoice rather than a second subscription to track.
Plan changes produce invoices nobody needs to query.
We provide subscription billing billing integration services London clients use to connect the website to their billing engine, CRM, data warehouse and accounting software. Sign-ups create accounts in the CRM, payments reach the ledger and product usage flows back to the account page, all monitored so a failed sync raises an alert.
Sales, finance and product read the same numbers.
Smart retries timed to card authorisation patterns, emails and in-app notices that ask the right contact to update details, and a grace period before access changes. Enterprise accounts on invoice terms get reminder sequences from your finance team's address instead, with the sales owner copied when an invoice passes its due date.
Fewer accounts lost to expired cards and missed invoices.
Where some customers are sole traders or consumers, cancellation is reachable online in a few steps, renewal reminders go out on time and terms are shown before payment. The subscription rules in the 2024 Act are expected in 2027, so we build these features in a way that needs settings, not new code, when the detail is final.
Ready for the expected rules without a rebuild.
Integration pages, feature pages and honest comparisons with alternatives, edited by your marketing team in the CMS and built on fast, accessible templates with structured data. London buyers search for billing tools by the systems they already run, so integration pages often bring the most qualified visitors.
Search traffic that already knows what it needs.
Who this is for
London has billing and revenue software companies at every stage, from seed funded teams in shared workspaces to established firms selling into banks and global retailers. The commercial website changes with the stage and with who is buying. We build subscription billing SaaS website development London teams can grow into, starting with the release that removes the biggest blocker to sales today and leaving room for the next stage without starting again.
You need a credible site that takes card payments, explains three or four plans and gets customers into the product without a founder on every call. We keep the first release tight: pricing, checkout, account basics and a help centre. The CMS lets a non technical founder change copy and add integration pages, and the analytics show which plan pages lead to paid accounts.
Small first release, clean foundations.
Self-serve revenue is steady, and now larger London firms are asking for contracts, invoices by purchase order and security reviews. We add the enterprise route, the trust centre, team accounts and single sign-on, while keeping the self-serve path exactly as fast as before. Sales and finance agree the handover rules, and we write them into the site logic.
If your product touches payments or customer money, your own buyers may be regulated by the FCA and will ask how your site and platform handle data and access. We make sure the website says only what is true, keeps marketing claims clear and accurate, and routes regulated questions to the people qualified to answer. Data handling follows UK GDPR, with logs your compliance lead can review.
Accuracy on the site is part of the product.
Some London billing companies earn most of their revenue in Europe and North America. The site needs currency pricing, localised terms, tax logic per region and content written for buyers who have never heard of Bacs. We keep British English for UK pages where that suits your brand and use regional variants elsewhere, with hreflang set correctly. London remains the brand home, with the UK entity shown where buyers expect it.
How we work together
Early teams usually take a fixed scope first release, then a monthly retainer for new pages, plans and integrations. Scale-ups often take a dedicated team for subscription billing subscription platform development London buyers will use daily, covering the website, account portal and integrations together. Cost depends on currencies, payment methods, enterprise features such as single sign-on, the number of integrations and how much existing content and customer data must move. We put each scope in writing so you can see what drives the estimate.
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 fit the stack to your billing engine and your engineers. Next.js with a headless CMS is common, connected to Stripe Billing, Chargebee, Recurly, Maxio or your own platform, with hosting in the region your data commitments require and monitoring your team can read. Pages are built to pass Core Web Vitals on mobile, because many buyers first see your pricing on a phone between meetings.

It depends on scope, so we price after discovery rather than guess.
The main drivers are the number of plans and currencies, whether you need an enterprise route with single sign-on and team accounts, the payment methods, the tax regions you sell into and how many systems the site must update. Content volume and migration from an old site add to it. After discovery we give a written estimate with each driver shown separately, so you can move items to a later release if that suits your runway.
