Services · Ecommerce development · AI chat agent subscription sites
Codeeo builds subscription websites and billing platforms for Birmingham businesses that sell AI chat agents, especially to manufacturers, distributors, professional firms and operators with many sites across the West Midlands. We cover pricing per branch or per user, language add ons, annual contracts with staged invoicing, Open Banking and Direct Debit collection, and an account area where a group finance team can see every subsidiary's usage in one place.
The work here is the selling and billing platform around your agent, not the agent's own software. Codeeo does not have a Birmingham office; we work with Birmingham clients remotely, and all discovery and review sessions run by video call.

Core features
Birmingham's customer base for AI chat agents looks different from a pure tech hub. Many buyers are engineering suppliers and distributors around the region, accountancy and law firms in the Colmore Business District, creative studios in the Jewellery Quarter and Digbeth, and groups running clinics, branches or depots across several towns. They tend to buy on annual terms, pay by invoice, want a named contact and ask for one bill that splits cost by site or department.
That buying style calls for B2B billing first and card checkout second. The features below reflect it, and every one sits on top of a pricing page that shows the full cost clearly, as UK consumer protection law and plain good sense both require. Card checkout still matters for smaller customers, so it sits alongside these tools rather than being dropped.
A group with a dozen branches pays per location, with each branch able to run its own agent configuration. Adding a site prorates the charge to the renewal date, and billing for a closed site ends at the end of the period. Group admins see a single invoice with a line for each site and cost codes for their accounts team.
Multi site customers expand one branch at a time.
Holding companies often want central billing while subsidiaries manage their own agents. We model account hierarchies so usage rolls up to the parent, invoices can go to either level, and permissions stop one subsidiary's staff from seeing another's conversation data or spend.
Group finance gets control without blocking local teams.
Birmingham businesses serve customers who speak Punjabi, Urdu, Bengali, Polish and many other languages. If your agent supports extra languages, the platform can sell them as add ons with their own allowance, shown clearly on the plan page and invoice, so customers pay only for the languages their callers and visitors actually use.
Language support priced in a way buyers understand.
Many trade and professional buyers sign annual agreements but pay monthly or quarterly. The platform holds the contract value, issues invoices on the agreed schedule, tracks committed versus actual usage and prepares the renewal quote well ahead of the end date, with the notice period stated in your terms.
Predictable revenue for you, predictable budgets for them.
Invoices carry a pay link that lets the customer approve an Open Banking payment from their business account, with funds matched automatically to the invoice. Bacs Direct Debit remains available for regular collections and cards for smaller accounts, so each customer pays in the way their finance team prefers.
Invoices paid sooner with less manual matching.
Overdue invoices trigger polite reminders at stages you set, a statement of account, and a task for your credit controller. Service can move to a restricted mode after a defined period, with warnings first, so the agent does not stop answering a customer's buyers without notice.
Cash collected without damaging the relationship.
Large accounts negotiate their own rates. Those agreements are stored against the customer with start and end dates, applied automatically to usage and visible to sales, finance and support. When an agreement ends, the platform prompts a renewal discussion instead of silently reverting to list price.
Negotiated terms honoured exactly as signed.
When you raise prices, the platform sends notices on the schedule your contracts specify, records who received them, and applies new rates only from the right date for each customer. Annual and monthly customers are handled separately, and anyone on a fixed term keeps their rate until renewal.
Price increases that stick without disputes.
Product, pricing and sign up pages built to WCAG 2.2 AA, with keyboard access, readable contrast and clear form errors. Public sector and housing buyers in the region often require an accessibility statement from suppliers, and accessible pages support your customers' own duties under the Equality Act.
Fewer procurement objections from public bodies.
Customers download monthly reports showing conversations, resolutions and handovers by branch, department or cost centre, matched to the invoice lines they pay. Finance teams use them to recharge internal departments, and operations managers use them to spot which locations rely on the agent most. Reports export to spreadsheet formats without any manual tidying.
Customers can justify the spend internally at renewal.
Who this is for
AI chat agent SaaS website development in Birmingham usually serves vendors whose customers are businesses with established purchasing habits. Those customers rarely sign up on a whim with a card; they compare suppliers, request a quote, and expect invoices that slot into their accounting. The platform needs to respect that while still giving smaller customers a quick self serve route. Across the West Midlands, the vendors who benefit most share one trait: their sales process already works, and billing is the part slowing it down.
Your agent answers stock, lead time and product specification questions for industrial suppliers. Those customers want annual terms, purchase orders and invoices, plus per user pricing for sales staff who use the agent internally. We build quote requests from the pricing page, contract billing, and account areas that a purchasing manager can understand without a demonstration from your sales team.
Industrial buyers value clear invoices over clever pricing.
Accountants, solicitors and surveyors around Colmore Row adopt agents for client intake and routine questions. They are cautious about confidentiality and expect a data processing agreement before signing. We build a trust section with your DPA and sub processor list, seat based plans for fee earners and support staff, and invoicing that lines up with practice management billing periods. Many such firms also ask where data is hosted, so the answer sits on the page rather than in an email thread.
Dental groups, care providers, vehicle dealers and trade counters run many locations. They want branch level agents, branch level reports and one consolidated invoice. We build the account hierarchy, per site pricing and group dashboards so a regional operations manager in Solihull or Wolverhampton can see the same figures as head office in Birmingham.
Digital studios in the Jewellery Quarter and Digbeth have built agents for clients and now want a repeatable subscription product. We package their work into plans, launch a branded site with checkout and onboarding, and set up billing so they can stop raising one off invoices for every change a client requests. Change requests then become add ons or plan upgrades with a visible price, which keeps client relationships clearer on both sides.
How we work together
A fixed scope project suits vendors replacing manual invoicing with a proper platform; its cost follows the number of contract types, payment methods, integrations and customers to migrate. A retainer keeps the platform moving as you add products, regions or languages. A dedicated developer suits vendors with their own engineering team who want an extra pair of hands on billing. Every option runs remotely, with Birmingham clients reviewing progress on video calls and a shared project board. The engineers who scope your platform are the ones who build it, and they remain your contacts after launch.
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
Often Laravel or Next.js for the site and portal, Chargebee or Stripe Billing for contracts and subscriptions, GoCardless for Direct Debit and pay by bank, and integrations with Sage, Xero, QuickBooks, HubSpot or Microsoft Dynamics 365. We favour tools your finance team already understands. Hosting regions, backups and access are agreed with you, and every service account is registered to your business so nothing depends on us staying involved.

Your contract types, payment methods and integrations.
A simple card checkout with a few plans costs far less to build than a platform with account hierarchies, negotiated pricing, staged invoicing, Open Banking collection and accounting integration. Migrating existing customers and contracts also adds effort. We price after discovery, list each driver in the proposal and suggest which features could wait for a later phase. The output of discovery is a written scope you keep whether or not we build the platform.
