Services · Ecommerce development · Inventory management subscription sites
Codeeo provides inventory management subscription website development UK software vendors use to sell stock control by monthly or annual plan, nationwide. We build the pricing site, checkout, recurring billing, VAT invoicing and customer account area, set up for how British businesses buy and pay: Direct Debit, card with Strong Customer Authentication, invoice terms for larger accounts and pay by bank. Customers from a Cardiff wholesaler to a Belfast distributor can sign up, change plan and settle invoices without your team stepping in.
Selling across the whole country brings questions a single city vendor rarely meets: Scots law contracts, Welsh language expectations, Northern Ireland goods rules, accountants acting as resellers, and VAT reporting under Making Tax Digital. The platform handles them as configuration rather than special cases. Each is switched on only where you need it.

Platform scope
Inventory software reaches British businesses through several routes at once. Some customers find you in search and sign up alone. Some are introduced by their accountant or bookkeeper, who may manage the subscription for them. Larger groups buy through a sales process with a contract and purchase orders. A national platform has to serve all three without three separate billing setups.
It also has to meet national rules consistently: VAT invoices HMRC will accept, data handling that satisfies UK GDPR and the ICO, cookie consent under PECR, and price display that respects the Digital Markets, Competition and Consumers Act 2024. Here is what we build, ordered from the public pages to the back office. Not every vendor needs all ten on day one; we agree with you which ones belong in the first release and which can wait for evidence from paying customers.
One plan catalogue drives the pricing page, checkout and invoices, so nothing on the site can disagree with what customers are charged. Plans can be priced by locations, SKUs, users or orders, with a comparison table and an estimator built on the units your product actually tracks.
A single source of truth for every price you publish.
Many small UK businesses adopt software on their accountant's advice. We build a partner area where accountants and resellers open client accounts, choose who pays, receive wholesale or referral pricing and see commission statements based on paid invoices. Clients can move to direct billing later without losing history.
A sales channel that scales with no extra admin.
Company name lookup against Companies House data to fill details and reduce typing errors, plus VAT number capture. Your team can flag accounts for manual review where a higher risk plan or invoice terms are involved.
Cleaner customer records from the first day.
Bacs Direct Debit for recurring collections, cards with Strong Customer Authentication at the first payment, Apple Pay and Google Pay, and Open Banking pay by bank through an FCA authorised provider. Customers choose; your billing logic stays the same.
Payment options that match how UK firms prefer to pay.
VAT invoices with the required details, credit notes for adjustments, and a clean sync of invoices and payments to Xero, Sage, QuickBooks or Business Central. Your quarterly VAT figures come from the same records your customers see. Adjustments never require editing an issued invoice.
VAT returns built on data nobody has rekeyed.
Contract terms selectable by jurisdiction where your lawyers want Scots law wording, Welsh language pages and emails where you choose to offer them, and add-ons for Northern Ireland customers whose stock moves under the Windsor Framework if your product supports that.
Customers in every nation see terms and language that fit them.
Plan and add-on changes with the price effect shown first, user management, payment method updates, invoice downloads and cancellation. Rules such as upgrades now and downgrades at renewal are applied consistently for every customer.
Routine admin handled by customers themselves.
Retry schedules matched to card and Direct Debit rules, reminder emails, in product notices and staged restrictions that never delete stock data. Invoice customers receive statements and reminders before and after the due date. Access resumes the moment the account is settled.
Overdue revenue recovered with less manual chasing.
Pricing tables, forms, checkout and the portal built to WCAG 2.2 AA, tested with keyboards and screen readers. Public sector bodies and larger buyers increasingly check accessibility, and it supports your duties under the Equality Act.
A buying process every customer can complete.
Recurring revenue, churn and expansion by channel, plan and region, sent to Power BI or your data warehouse. You can see how the accountant channel compares with direct sign ups, or how Scotland performs against the English regions.
Growth decisions grounded in billing data.
Who this is for
The UK stock software market runs from long established vendors with thousands of small business customers to newer cloud products growing through ecommerce agencies and accountancy firms. Subscription platform development UK vendors commission tends to fall into four patterns, each shaped by how the product reaches its customers and how far across the country those customers are spread. Customers in Aberdeen, Swansea, Newcastle and Belfast should all find the same clear pricing and the same quick sign up, even though their terms, language preferences and payment habits may differ.
Bookkeepers and accountancy practices recommend your product to their clients and sometimes pay for it on their behalf. You need partner accounts, client switching, flexible payer rules and commission statements. We build that partner layer on the same billing records as direct customers, so nothing is reconciled by hand. Accountants also get a simple way to move a client to a higher plan when the client's stock grows.
Partner billing often decides how fast a vendor can grow.
Your stock software has served UK businesses for a long time, and renewals still rely on annual invoices and phone payments. We move customers to Direct Debit or card with their existing terms, open online sign up and give finance clean recurring revenue reporting. Customers who prefer to keep paying by invoice can, with reminders and statements sent automatically.
You started with customers in your home city and now sell across England, Scotland, Wales and Northern Ireland. We add jurisdiction aware terms, optional Welsh language content, regional reporting and a sales assisted route for larger multi site customers. Sales teams in different regions see their own accounts and renewals in the CRM.
National reach without separate sites per nation.
Your customers run branches and depots in several regions and buy centrally. They need per location pricing, purchase order numbers, consolidated invoices and an account owner who can add sites. We build those into plans and the portal. Each site can be added from the portal, with the price effect shown before it is confirmed.
How we work
Codeeo is a team of 80+ across Dubai, Riyadh and Karachi. We have delivered 200+ projects across the UAE and the US and are rated 4.7 from 23 Google reviews. We have no UK office and work with UK clients remotely: discovery, design reviews and demos run by video call, with written decisions after each session. Cost is driven by the number of sales channels, partner billing rules, payment methods, integrations, any bilingual content and the size of the customer migration.
The inventory management billing integration services UK vendors ask for most often join the billing provider, the product and the finance system, and that is where we put most of the testing. Inventory management SaaS website development UK buyers trust also depends on plain pricing copy, which we draft with your team early. Where a cheaper route would do the same job, such as a hosted checkout instead of a custom one, we say so early.
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 combine Next.js or WordPress for the public site, Stripe Billing or Chargebee for subscriptions and VAT, GoCardless for Bacs Direct Debit, and Laravel or Node services for partner logic and product entitlements. Finance data syncs to Xero, Sage, QuickBooks or Business Central.

Pricing site, checkout, billing, partner channel and customer portal.
For a nationwide vendor we build the public pricing and sign up pages, recurring billing with British payment methods, VAT invoicing and accounting sync, an accountant or reseller area if you sell through partners, and a customer portal for plan changes and invoices. We also connect your product so it enforces each customer's plan limits. The inventory product itself stays with your engineering team unless you want us to work on it. Where your product already has a billing module, we assess whether to extend it or replace it before recommending either, and explain the trade-off in plain terms.
