Subscription billing for voice AI products sold to customers across Britain.

Codeeo offers AI voice agent subscription website development UK software companies rely on to sell plans nationally: pricing pages that satisfy British consumer law, checkout with cards, Direct Debit and pay by bank, metered billing for call minutes and phone numbers, VAT correct invoices, and self serve plan changes. Customers in England, Scotland, Wales and Northern Ireland buy on the same platform, with terms, tax and payment rules handled consistently.

Selling voice agents across the country means meeting rules set in Westminster, by the regulators and by the payment schemes, all at once. We build the subscription site so those rules sit in configuration rather than in someone's memory.

Platform features

The national rules, built into how customers buy and pay.

A UK subscription platform for voice agents has to price usage fairly, take payment in the ways British businesses expect, and keep records that stand up to HMRC, the ICO and, for consumer sales, the Competition and Markets Authority. It also has to work for a sole trader in Cardiff and a housing group with offices in several regions. The features below are the national foundations we put in place, so you can sell anywhere in the country from one catalogue and one set of records. Regional differences, such as Scottish terms or Welsh language pages, are layered on top rather than built as separate sites.

Explain your project
  • Transparent all in pricing

    Headline prices include every unavoidable charge, such as platform fees or compulsory number rental, with usage rates shown in plain terms beside them. The same price data feeds the pricing page, checkout and invoices, so what customers see never drifts from what they pay.

    Pricing meets current UK expectations on transparency.

  • Business or consumer at checkout

    The checkout asks whether the buyer is acting for a business, collects company or VAT details where relevant, and applies the right terms. Consumer buyers see cancellation information before paying and can ask for the service to start immediately.

    Each customer gets the contract and rights that apply to them.

  • Card, Direct Debit and pay by bank

    Cards handle instant activation with Strong Customer Authentication on the first payment. Bacs Direct Debit suits variable monthly bills. Open Banking payments can be added for one off top ups where your provider supports them.

    Customers pay in the way they prefer, and you collect reliably.

  • Metered usage with rating rules

    Call minutes, numbers, recordings storage and premium voices are rated from your voice platform's usage data, with allowances, tiers and overage applied consistently. Corrections create credit notes rather than silent edits, which keeps the audit trail intact.

    Every usage charge can be traced to the calls behind it.

  • VAT and invoice compliance

    Invoices carry the details HMRC expects, apply VAT by customer location and status, use the reverse charge for qualifying overseas business buyers and export cleanly to accounting software that supports Making Tax Digital.

    Finance teams spend less time fixing invoices.

  • Self serve account and plan changes

    Customers upgrade, downgrade, add numbers, invite users and update payment details in a portal, with proration calculated automatically and confirmation by email. Support staff can make the same changes on a customer's behalf with a logged reason.

    Routine account changes no longer need a support ticket.

  • Renewal reminders and online exit

    Reminders before renewal, a clear record of what each customer accepted, and cancellation online in the same number of steps as joining. These are good practice now and prepare the platform for the subscription contract rules expected in 2027.

    The platform is ready for tighter subscription rules.

  • Dunning that protects service

    Failed payments trigger retries, reminders and a grace period you control. Lines serving urgent purposes, such as housing repairs or care services, can be kept answering in a limited mode rather than cut off, and every step is logged for later review.

    Revenue is recovered without leaving callers unanswered.

  • Company disclosures and trust content

    The site shows your registered company name, number, registered office and VAT number as the trading disclosure rules require, plus a privacy notice, cookie controls under PECR, an accessibility statement and a security page for buyers.

    Buyers can check who they are dealing with before they pay.

  • Regional and sector reporting

    Sign ups, revenue, usage and churn are reported by UK nation, region and sector, so sales and partner efforts go where demand is strongest and pricing can be tested in one area before a national change.

    Expansion decisions use evidence from across the country.

Who this is for

Four UK situations we design for.

National selling raises different questions from selling in one city. Terms must suit customers under English and Welsh law, Scots law and Northern Irish law; tax must be right for every buyer; and sales may come through partners in several regions at once. These are the four situations we most often find.

01

A UK vendor moving from one city to national sales

Many vendors start with customers near their base and a billing set up that grew informally. Going national exposes the gaps: inconsistent terms, invoices missing details, prices that differ by salesperson. We put a single plan catalogue, a compliant checkout and standard invoices in place, and give regional sales staff tools to quote from the same catalogue rather than from their own spreadsheets. Existing customers are moved onto standard terms at renewal, with notice, so nobody is surprised by a change mid contract.

Consistency matters more as the customer base spreads out.

02

An overseas vendor entering the British market

US, European and Gulf based voice AI firms often reach British buyers with a site built for home. We localise for the UK: sterling pricing, VAT registration details, UK GDPR wording, a UK representative where your lawyers say one is needed, British English and payment methods UK buyers use. The underlying product catalogue can remain shared across markets, and reports separate UK revenue so you can judge the market on its own results. Discovery also checks whether your existing billing provider can issue UK VAT invoices properly before anything is replaced.

03

A vendor selling to public sector suppliers and housing groups

Organisations that serve councils, NHS bodies or social housing tenants often buy through frameworks or formal tenders, then pay by invoice. They scrutinise accessibility, data protection and security. The site gives them a clear procurement page, downloadable policies and invoice billing, while the self serve route stays open to smaller buyers. Tender teams can download the documents they need without waiting for a sales call, and your team sees which organisations requested them.

Frameworks reward suppliers whose paperwork is ready.

04

A product with Welsh or multi language voices

If your agents speak Welsh or other languages used in UK communities, the plans and portal should explain what is included in each. Where you serve Welsh public bodies or their suppliers, a Welsh language version of key pages may also be expected. We plan translation and language specific pricing from the start, so adding a language later means adding content rather than restructuring templates, checkout steps and invoices.

Language support is easier to plan in than to retrofit.

Six stages for a national subscription platform.

  1. 01Commercial and legal inputsPlans, usage units, payment methods, VAT position and draft terms are gathered, with open legal questions listed for your advisers before design begins.
  2. 02Billing architectureWe choose or confirm the billing provider and design how usage, credits, taxes and invoices flow between it, your voice platform and accounting.
  3. 03Checkout and portal designPricing, business or consumer selection, payment, number selection and account pages are designed and tested for clarity and accessibility on mobile and desktop.
  4. 04Build and integrationFront end, billing configuration, usage rating, CRM and accounting connections are built in sprints, each demonstrated on staging.
  5. 05Compliance reviewYour legal, finance and data protection leads review pricing wording, terms, invoices, cookie behaviour and cancellation flows before anything is public.
  6. 06Phased national rolloutExisting customers migrate in groups, new sign ups open region by region if you wish, and reports are watched closely after each step.

UK questions about voice agent subscription platforms

Scope, integrations and how many buyer types the platform serves.

A self serve site with a few plans and one payment method is the lightest build. Effort grows with usage rating complexity, Direct Debit and pay by bank alongside cards, business and consumer routes with different terms, invoice billing for larger buyers, partner accounts, multi currency, and the number of systems connected. Migration of existing customers and Welsh or other language versions also add work. We give a written estimate after discovery, broken down so you can choose what to include in the first release. Ongoing support and hosting are scoped separately, so you can see what the platform needs after launch.
