Services · Ecommerce development · POS subscription sites
Codeeo offers POS subscription website development London software companies use to sell till plans online. The site shows your plans clearly, signs a merchant up with their Companies House and VAT details, takes the first payment with Strong Customer Authentication, sets up recurring card or Direct Debit billing, and lets each customer add sites, change plans and download VAT invoices without calling your team. It suits vendors whose customers range from a single Camden stall to a hospitality group with twenty venues.
This page covers the commercial website, not the till. Your POS product keeps its cashier screen, kitchen display and offline mode. We build what sits around it: pricing, checkout, billing rules, invoices, the account area and the link that switches each subscription on inside your platform.

What the platform covers
London has more POS vendors competing for the same merchants than anywhere else in the UK, and many of them are based around Old Street, Shoreditch and King's Cross. A buyer comparing three till systems on a Sunday evening will not book a demo just to learn what a second site costs. If your pricing page cannot answer that, a competitor's will.
London customers also buy in very different ways. A Soho bar owner pays by card from a phone. A group finance team in the City wants one consolidated invoice, a purchase order number on it and payment by Direct Debit. A franchise operator wants each franchisee billed separately but reported centrally. The items below are what a POS subscription platform development London project usually needs. Every item connects to the same customer record, so a change in one place shows everywhere. We cut what you will not use and add what your sales model requires.
Plans laid out by venue type, with per-site and per-terminal costs shown clearly, VAT shown both ways for business buyers, and add-ons such as kitchen screens or loyalty listed with their own price. The figures come from your billing system, so the page never shows a stale price after a change.
Buyers can work out their own monthly cost without booking a call.
A limited company enters its name and the form fills registered details from the Companies House API. Sole traders and partnerships take a shorter path. VAT numbers are captured for invoices, and trading addresses are kept separate from registered offices, which in London are often an accountant's address.
Accurate customer records from the first minute.
The first card payment goes through a 3D Secure challenge where the bank asks for one, and the card is stored for later merchant-initiated charges. Where you prefer Direct Debit, the Bacs mandate is set up online with the advance notice and Direct Debit Guarantee wording the scheme requires.
Later renewals go through without the customer being asked again.
One parent account with many venues under it, each with its own plan and terminals. Group buyers choose a single consolidated invoice or one invoice per site, add purchase order references, and give finance staff billing access without till access.
Large London groups can buy from you on their own terms.
When a venue adds terminals mid month or moves to a higher plan, the platform works out the proportional charge, explains it before confirmation and shows it as a separate line on the next invoice. Downgrades take effect at the end of the period unless you set another rule.
Plan changes stop turning into support tickets.
Failed renewals trigger card retries, reminder emails and a banner in the account area. You choose how long a venue keeps trading before features are limited, so a Friday night service is never cut off because a card expired on Thursday.
Recovered payments without angry calls to your support desk.
Terminals, printers and cash drawers sold as one-off items alongside the subscription, with stock checks, delivery to the trading address and notes for venues with restricted delivery windows or basement access.
One checkout covers the plan and the kit it runs on.
Customers view plans, add or remove sites, update cards and mandates, download VAT invoices and request cancellation with the notice period your terms set. Roles separate owners, finance and venue managers.
Routine billing questions answered without your team.
When a subscription starts, changes or ends, a webhook tells your POS platform which licences to switch on, which terminals to allow and which features belong to the plan. We build and test this against your API or a staging copy of it.
What a customer pays for matches what their tills can do.
Paid invoices, credit notes and refunds post to Xero, QuickBooks or Sage so your finance team reconciles without exports, and new sign-ups appear in HubSpot or Salesforce with plan, site count and payment status. These POS billing integration services London vendors ask for are agreed in discovery, so the first release links the systems your month end actually depends on.
Finance and sales see the same customer numbers as the billing system.
Who this is for
The work differs depending on who sells and who buys. A venture-backed POS start-up near Old Street has a product team and wants a fast self-serve funnel. An established reseller in outer London has loyal customers on paper contracts and wants them moved online without losing anyone. We start by understanding which of these you are, because it changes the checkout, the billing provider and how much of the sale stays with a person. A POS SaaS website development London brief from a start-up and one from a long-standing reseller can share a billing provider and still need very different sites, so we write the scope around your customers, not around a template.
Your sales team books every customer by video call and sends a payment link afterwards. We build a site where smaller venues can buy alone, while larger groups still reach a person. The pricing page, trial settings if you offer one, and the checkout are designed so the self-serve path does not undercut quotes your team has already sent.
Usually the first project for a newer vendor.
You resell a POS brand across London and invoice manually each month. We move existing customers onto recurring billing with migrated mandates or fresh card authorisations, keep their contract dates, and give them an account area for the first time, so your office stops issuing invoices by hand.
Migration planning matters more than design here.
Your best customers run many venues across several boroughs and buy through procurement. They need quotes accepted online, purchase order numbers, consolidated invoicing and finance roles. We build the group account model first, then the simpler single-venue path on the same rules. Approval steps can be added where a group's operations director signs off a new site before its terminals are switched on.
You already process card payments for London merchants and now sell software on subscription. The site joins the two: merchant onboarding with your FCA-authorised payment partner, the POS plan, and one account area. We keep the regulated onboarding inside your provider's flow and build everything around it.
Regulated steps stay with your authorised provider.
How we work together
Codeeo has no London office. Our team of 80+ works from Dubai, Riyadh and Karachi and runs discovery, design reviews and progress meetings with London clients by video call. Most vendors start with a fixed scope build for the site and billing integration, then keep a retainer for pricing changes and new features. Larger vendors sometimes take a dedicated team that works inside their own product process. Retainers usually cover new plans, price reviews, extra payment methods and changes to your POS API, planned month by month with your product lead. We have delivered 200+ projects across the UAE and the US.
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
Usually Next.js or Laravel for the site and account area, a billing platform such as Stripe Billing or Chargebee for plans and invoices, and GoCardless where Direct Debit matters. We choose against your existing stack and the team who will maintain it.

It depends on billing complexity and migration, not page count.
A vendor with three plans, card payments and no existing customers to move is a much smaller project than one with group accounts, Direct Debit, hardware bundles and hundreds of venues on old contracts. We map those factors in discovery and put an agreed timeline in the scope before design begins, so you can plan your launch around it. We also note which London venues tend to open on short notice, such as market pitches and pop-ups, because they need a faster path from sign-up to a working till.
