Services · Ecommerce development · AI sales assistant subscription sites

Subscription sites that sell your AI sales assistant to buyers across the UK.

Q: Do UK consumer rules apply if we sell only to businesses?

Mostly not, but the line is less clean than it looks. The Consumer Contracts Regulations protect consumers, not companies buying for their trade. In practice, sole traders and very small firms sometimes buy in ways that look personal, and some parts of the DMCC Act, including the drip pricing rules, are written around consumers. We design the site so business buyers declare that they are buying for business purposes, and so any consumer route that does exist carries the right information and cancellation rights.

Q: What does the DMCC Act change for subscription billing?

Drip pricing rules apply now; subscription contract rules are expected in 2027. The drip pricing rules mean compulsory charges must be included in the headline price, which affects how pricing tables and checkout totals are shown. The Act also creates new rules for subscription contracts covering pre-contract information, reminders and easy exit, which are expected to take effect in 2027. We build reminders, renewal notices and cancellation so they can be switched on or adjusted once final guidance is published.

Q: How does Strong Customer Authentication affect renewals?

The first payment is authenticated; later renewals usually are not. When a customer first subscribes by card, the payment normally goes through 3D Secure. Later renewals are flagged as merchant-initiated transactions linked to that first mandate, so the issuer rarely asks the customer to authenticate again. Upgrades that change the amount, card updates and some high-risk payments can still trigger a challenge, so the dunning flow includes an authentication step customers can complete from an email link.

Q: Can customers pay by Direct Debit or open banking?

Yes, alongside cards. Many UK businesses prefer Bacs Direct Debit for anything recurring, especially annual or multi-seat plans. We set up mandates, advance notice emails and failed collection handling through a Direct Debit provider you choose. Open banking payments can work well for one-off annual invoices, though recurring payments by that route are still developing, so we usually recommend them for invoices rather than monthly plans.

Q: Where will customer and billing data be held?

In accounts you own, in regions agreed with you. Payment card data stays with the payment provider, so your platform never stores full card numbers. Customer, subscription and invoice records sit in your billing engine and database, hosted in the UK or another region with adequate transfer safeguards, as you decide. We document the processors involved so your privacy notice and records of processing reflect them, which the ICO expects you to be able to show.

Q: What drives the cost of a subscription platform?

Pricing complexity, payment methods, integrations and migration. Usage metering costs more to build than flat seats because every billable event must be counted reliably. Each extra payment method, accounting connection or CRM sync adds work, as does a sales-led quote path. Migrating live subscriptions is often the largest single item. We price after discovery, from a written scope, so you can decide which parts belong in the first release.

Q: Will the site be accessible to disabled buyers?

We design and test to WCAG 2.2 AA. Pricing tables, forms, error messages and the account area are built for keyboard use, screen readers and zoom, with enough contrast and clear focus states. That supports your duties under the Equality Act to make reasonable adjustments, and it matters commercially because buyers increasingly ask about accessibility in procurement. We test with automated tools and by hand before launch.

Codeeo handles AI sales assistant subscription website development UK software companies use to sell plans, collect recurring payments and let customers manage their own accounts. We build the pricing pages, sign-up, card and Direct Debit billing, VAT invoices and the customer billing area for vendors whose product qualifies leads, drafts outreach or books meetings for other businesses. The result is a sales channel that runs without a person approving every new account, and that already reflects UK consumer, payments and data protection rules.

This page is about the commercial side of your product: how buyers choose a plan, pay, upgrade and leave. The assistant itself stays your product; we connect the billing platform to it so access follows payment status automatically.

Plan your subscription site Web development and eCommerce

Built for: Software companies selling AI sales assistants, outreach tools and sales copilots to UK businesses, from early stage vendors to established platforms.

What the platform covers

The parts of a UK subscription business that customers and your finance team both touch.

A vendor selling an AI sales assistant nationally has two audiences on one site. Small firms in towns from Aberdeen to Truro want to pick a plan, pay by card and be using the product within minutes. Larger buyers want a quote, a purchase order and an invoice their accounts payable team recognises. Your finance team, meanwhile, needs VAT handled correctly, failed payments chased and revenue reported in a way an accountant can audit.

We design the platform around those three groups. Each part below can be built on a hosted billing engine you already use or one we recommend after looking at your plan model, and each is connected to your product so a paid subscription opens the right features and a cancelled one closes them. It is AI sales assistant SaaS website development UK buyers can trust, not a template checkout with your logo on it. Nothing here depends on a particular region of the UK; the same rules and flows apply whether the customer sits in Belfast, Cardiff or Norwich.

Explain your project

Plan pages that show the full price
Pricing tables, plan comparisons and feature detail written so the total a buyer will pay is visible up front, including VAT treatment and any compulsory charges. Under the Digital Markets, Competition and Consumers Act 2024 the drip pricing rules are already in force, so mandatory fees cannot appear only at the last step.
Buyers see one honest price and trading standards complaints have nothing to grip.
Card and Direct Debit billing
Card payments for self-serve plans and Bacs Direct Debit for customers who prefer to be collected from a business account. Card sign-ups pass Strong Customer Authentication on the first payment, then renewals run as merchant-initiated charges so customers are not asked to approve every month.
Fewer abandoned sign-ups and fewer renewals blocked at the bank.
VAT logic and compliant invoices
VAT charged on UK sales, reverse charge wording for business customers abroad where it applies, VAT numbers captured and validated at checkout, and invoices numbered and stored the way your accountant expects. We build the rules your adviser signs off rather than guessing at tax treatment.
Invoices that survive a VAT inspection without manual correction.
Seats, usage and overage
Pricing for AI sales tools rarely stays simple. We meter the units you charge for, such as seats, conversations handled, contacts enriched or meetings booked, show customers their consumption in the account area and bill overage or prompt an upgrade at the thresholds you choose.
Revenue follows usage and customers are never surprised by a bill.
Upgrades, downgrades and proration
Customers move between plans themselves, add seats mid-cycle or switch from monthly to annual. Proration is calculated by the billing engine and explained on screen before the change is confirmed, so support does not spend afternoons reconciling part-month charges.
Plan changes happen without a ticket.
Dunning and payment recovery
Retry schedules for declined cards, reminder emails that link straight to a secure update page, grace periods you control and a clear point at which the assistant is paused rather than deleted. Transactional reminders sit outside PECR marketing rules, but we keep them strictly about the account.
Involuntary churn falls without nagging customers.
Quote to subscription for larger buyers
A sales-led path beside self-serve: a quote generated from the same price book, accepted online, converted into an invoiced annual subscription with purchase order numbers and payment terms, and provisioned automatically once signed.
Enterprise deals and card sign-ups share one source of truth.
Cancellation that meets UK rules
An online cancellation route as easy as signing up, confirmation emails, and for anyone buying as a consumer the cancellation information the Consumer Contracts Regulations require. The Act's specific subscription contract rules are expected in 2027, and we structure renewal reminders and exit flows so adapting to them is configuration rather than a rebuild.
You are ready for the next round of subscription rules before they land.
Entitlements wired to the product
Billing integration services connect payment events to your assistant: a successful payment opens seats and usage limits, a paused account stops outbound sequences safely, and a reactivated one restores settings without losing the customer's lead history or CRM mappings.
Access always matches what the customer has paid for.
Revenue and retention reporting
Monthly recurring revenue, new, expansion and churned revenue, failed payment rates and plan mix, reported from the billing data and exported to your accounting software, so board packs and VAT returns come from the same figures.
One set of numbers for finance, sales and investors.

Who this is for

Four UK vendors this kind of platform suits.

The right subscription site depends less on the size of your company and more on how your customers like to buy. A tool aimed at sole traders lives or dies on a quick card checkout. A platform sold to national retailers or housebuilders needs invoicing, approvals and contracts. Most UK vendors of AI sales assistants sit somewhere between, and the build should match where your revenue actually comes from today, with room for where you want it to come from next year.

Product-led tools moving off a payment link

You launched with a hosted checkout link and a spreadsheet of customers. It worked for the first few hundred accounts, but plan changes, refunds and VAT invoices now take hours each week. We replace the workaround with a proper subscription platform, migrate active customers without asking them to re-enter card details where the provider allows it, and give them a self-serve billing area so your founders stop doing account admin.

Card migration depends on what your current provider supports.

Vendors adding a sales-led tier

Self-serve revenue is steady, but larger UK companies keep asking for invoices, annual contracts and a named contact. We add a quote to subscription path, purchase order fields and payment terms beside the card checkout, priced from the same plan catalogue so sales and self-serve never quote different numbers for the same product.

Platforms expanding from one nation to the whole UK

You built a following in England and now have customers in Scotland, Wales and Northern Ireland. Billing law is largely shared across the UK, but contract terms, consumer remedies and how you describe them can differ, and some Welsh public bodies expect bilingual material. We plan terms pages, invoices and optional Welsh content so the site reads correctly wherever the buyer is.

Your solicitor confirms the terms wording for each nation.

International vendors entering the UK

Your product already sells in the US or the EU and you want a UK storefront. That means GBP prices, UK VAT registration reflected on invoices, UK GDPR and ICO expectations in your privacy notice, PECR-compliant consent for marketing email, and accessibility to WCAG 2.2. We localise the commercial layer rather than translating a foreign checkout, and keep one billing engine behind every market so reporting stays consolidated.

Six stages from pricing model to a billing platform that runs itself.

01Pricing and billing modelWe map how you charge today and how you want to charge: seats, usage units, annual commitments, minimums and overage. Every rule is written down before anyone designs a pricing table.
02Compliance reviewVAT treatment, drip pricing, consumer cancellation rights, UK GDPR lawful bases and PECR consent are reviewed against the planned flows, with your accountant and solicitor confirming the points that are theirs to decide.
03Experience designPricing pages, sign-up, checkout, account area and cancellation designed and tested with real buyers over video, including keyboard and screen reader checks against WCAG 2.2.
04Billing engine and integrationsPayment provider, billing engine, accounting software, CRM and your product's entitlement service connected through their APIs, with webhooks handled idempotently so no payment is counted twice.
05Migration and launchExisting customers, subscriptions and payment methods moved where the providers allow, test renewals run against sandbox accounts, then a staged switchover with old and new billing reconciled.
06Iteration on revenue dataConversion, upgrade and recovery figures show which plans, pages and dunning steps need work, and changes ship in small releases rather than occasional rebuilds.

How we work together

Three ways UK vendors engage us.

We have no UK office. Our team of 80+ across Dubai, Riyadh and Karachi works with UK clients remotely, and discovery, design reviews and acceptance testing all run by video call with shared documents. For AI sales assistant subscription platform development UK vendors usually want a first release live quickly and refined against real revenue data. Most start with a fixed scope build for the first release, then keep a retainer for pricing experiments and billing changes. Companies with a long product roadmap sometimes take a dedicated team instead. We have delivered 200+ projects across the UAE and the US and are rated 4.7 from 23 Google reviews.

Fixed scope

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.

Questions UK software vendors ask before rebuilding their billing.

How long does AI sales assistant subscription website development take for a UK launch?

It depends mainly on billing complexity and data migration, not page count.

A vendor with simple seat plans and no existing customers to move needs far less work than one with usage metering, annual invoiced contracts and a few thousand live subscriptions on an old system. We agree a dated plan at the end of discovery, after we have seen your price book, provider accounts and integrations. The plan names each release and what it includes, so you can launch self-serve first and add the sales-led path after.
