Services · Ecommerce development · AI voice agent subscription sites

Subscription sites that let London buyers self serve or go through procurement.

Codeeo delivers AI voice agent subscription website development London software companies use to sell their product two ways at once: a self serve checkout for teams that want to start today, and a quote, contract and invoice route for the banks, insurers and agencies that buy through procurement. Both routes feed one billing record, so minutes, seats and phone lines are charged correctly whichever door the customer came through.

London voice AI vendors rarely sell to one kind of buyer. A Shoreditch start-up and a Canary Wharf compliance team want the same product with very different paperwork. The website has to serve both without a separate system for each.

Built for
London companies that sell AI voice agents on subscription, from early stage teams in Shoreditch and King's Cross to scale ups with enterprise accounts in the City.
Typical timeline
Agreed after a discovery call that maps your plans, billing provider and sales process; the order of releases is written down before design begins.
What you own
The website code, the pricing configuration, the billing provider account and every customer and invoice record, held in accounts you control.

What the platform covers

Self serve plans and enterprise contracts on one billing spine.

A voice agent product is awkward to sell online. Part of the price is fixed, such as a platform fee or seats, and part moves with every call: minutes handled, numbers rented, transcription or premium voices. London buyers also split sharply. Smaller teams expect a card checkout and instant access; regulated firms in the City expect a security pack, a negotiated order form and payment by invoice against a purchase order. The parts below are what we build so one subscription platform handles both without manual reconciliation at month end.

Explain your project
  • Pricing page with a contact sales tier

    Public plans for smaller teams, each showing what is included and how overage minutes are charged, alongside an enterprise tier that opens a qualified enquiry form instead of a checkout. The comparison table is driven from your billing catalogue, so a price change happens once and appears on the page, in checkout and on the next invoice together.

    Public plans and enterprise enquiries come from the same source of truth.

  • Quote to order form flow

    Sales staff build a quote with committed minutes, seats and term length, send it for e-signature, and the signed order creates the subscription automatically. No one retypes a contract into the billing tool, and the customer receives a portal login the moment the order is countersigned.

    Signed deals turn into live accounts without manual set up.

  • Invoice and purchase order billing

    Enterprise accounts pay by bank transfer against invoices that carry their PO number, cost centre and VAT details. Payment terms, reminders and statements run from the billing provider, while card customers on smaller plans continue to pay automatically.

    Finance teams in large firms get invoices their accounts payable process accepts.

  • Metered minutes and committed volumes

    Call minutes flow from your voice platform into the billing provider as usage records. Contracted volumes are drawn down first, then overage is rated at the agreed rate, and the customer sees the position in their portal before the invoice arrives.

    Usage charges match what the voice platform actually logged.

  • Trust centre and security pack

    A gated area where prospects request your security documentation, data processing agreement, sub-processor list and penetration test summary. Requests are logged against the account in your CRM, which shortens the questionnaire stage most London enterprise deals pass through.

    Security reviews start with documents already prepared.

  • SSO and multi user accounts

    Customer admins invite colleagues, assign roles such as billing contact or agent builder, and on higher plans sign in through their own identity provider. Seat counts update the subscription automatically, with proration on the next invoice.

    Large customers manage their own users without raising tickets.

  • Multi currency checkout

    Many London vendors sell into Europe and North America from day one. Plans can be priced in more than one currency, with VAT treatment set by the buyer's location and status, and reverse charge wording on invoices to overseas business customers where it applies.

    International buyers see prices and tax in terms they recognise.

  • Live demo agent on the pricing page

    Prospects can call or speak to a sample agent from the browser before choosing a plan, if you decide to offer that. Demo minutes are capped, tied to the visitor's email and logged in the CRM, so sales staff see who tested the product and for how long, and the demo cannot be abused as free capacity.

    Visitors hear the product working before they commit, on terms you control.

  • Renewal and expansion tracking

    Contract end dates, notice periods and usage trends sit in one view, so account managers see which customers are close to their committed volume or coming up for renewal well before the date passes.

    Renewals are handled on time rather than discovered late.

  • Revenue reporting for founders and investors

    Recurring revenue, usage revenue, churn and expansion are reported separately, because a voice business with high minute volumes can look healthier or weaker than it is if the two are blended. Exports go to your accounting package and board pack.

    Board reporting reflects how the business really earns.

Who this is for

Four London vendors we build this for.

The right subscription website depends on who signs the cheque. A London vendor selling to independent restaurants needs a fast checkout and little else. One selling to wealth managers or insurers needs the procurement route to be just as polished as the pricing page. These are the four situations we see most often.

01

Seed and Series A teams replacing a payment link

Many voice AI start-ups around Old Street and King's Cross launch with a payment link and a spreadsheet of usage. That holds for the first handful of customers, then breaks when overage, upgrades and refunds arrive in the same month. We replace it with a proper plan catalogue, metered billing and a customer portal, keeping your existing billing provider where it is sound so you avoid a migration you do not need.

Usually the first project after product market fit.

02

Vendors selling into the City and Canary Wharf

Banks, insurers and wealth managers buy voice agents for client service lines, and their procurement teams ask for a data processing agreement, information on where recordings are stored, and evidence of FCA related controls the customer must meet. Their reviewers will read your website closely, so it needs a credible enterprise route, an order form process and invoice billing that matches their supplier onboarding.

Expect a longer sales cycle and plan the site around it.

03

Agencies reselling a white label voice agent

Marketing and customer experience agencies across Soho and Clerkenwell resell voice agents to their own clients under their brand. They need parent and child accounts, wholesale pricing, and the option to bill each end client directly or receive one consolidated invoice. The agency sets its own margin, sees usage per client, and can suspend a client account that stops paying without touching anyone else on its books.

04

Platforms expanding from the US into London

Some vendors open a London sales team before they rebuild anything, and arrive with a US billing set up priced in dollars, with sales tax logic and American terms. We localise it for British buyers: sterling prices, VAT, UK GDPR wording, British English and terms that fit English law, while keeping one product catalogue across both markets. Reporting then shows UK and US revenue side by side, in their own currencies, so the London team can see how its region is performing.

How a London subscription platform comes together.

  1. 01Revenue model workshopWe map every chargeable unit, from seats and minutes to numbers and premium voices, and decide which are public prices and which are negotiated, so the catalogue reflects how you actually sell.
  2. 02Billing provider decisionWe review the provider you have, or compare suitable ones, against usage rating, invoicing, multi currency, VAT and quote to cash needs, and write down the reasons for the choice.
  3. 03Pricing and enterprise route designPricing page, plan comparison, checkout, enterprise enquiry and trust centre are designed together, so a visitor always knows which route suits them.
  4. 04Usage pipeline and portal buildCall records from your voice platform become rated usage, and the customer portal shows plans, users, invoices and remaining minutes in near real time.
  5. 05Finance and CRM connectionsInvoices, payments and credit notes sync to accounting; deals, quotes and renewals sync to the CRM your sales team already works in.
  6. 06Parallel billing run and launchBefore switching over, we run a billing cycle alongside the old process and compare every invoice line, then move customers in planned groups.

Questions London vendors ask about subscription billing sites

It depends mostly on whether you need the enterprise route at launch or can add it later.

A self serve pricing page, checkout, usage billing and customer portal is the core. Adding quote to order form automation, invoice billing with purchase orders and a trust centre adds design, integration and testing work. We agree the release order in discovery, often putting self serve live first so revenue starts flowing while the enterprise route is completed. Migration of existing customers is planned separately, because moving live subscriptions safely takes careful testing rather than speed.
