We build Stripe payment integrations for UK businesses — subscriptions, one-off payments, invoicing and the webhooks that keep everything else in sync, connected straight into your CRM or database. A proper Stripe integration means the payment, the receipt, the subscription status and your own records all update together the moment money moves, rather than someone reconciling a spreadsheet against the Stripe dashboard at the end of the month.
The Stripe checkout page is the easy part; what usually goes wrong is everything downstream of it — a webhook that isn't verified properly and can be spoofed, a subscription that renews in Stripe but never updates your CRM, or a refund that's issued but nobody tells the customer or adjusts their access. We've seen plenty of 'basic' Stripe integrations that only handle the happy path and quietly fall over the first time a card gets declined or a customer disputes a charge.
Customer subscribes or pays → Stripe webhook verified → your CRM or database updated with the subscription status in real time
Card payment fails or a subscription lapses → customer notified automatically and access paused, rather than someone spotting it days later
Refund or partial refund issued → receipt sent, CRM record updated, and access adjusted automatically
Multiple products or tiers → checkout and billing handle upgrades, downgrades and proration without manual invoicing
Marketplace or multi-tenant payments → funds split and paid out to the right account automatically, claimed race-safe so two people can never take the same payment
Failed payment → automatic retry on Stripe's schedule, with a dunning email sequence so you're not chasing customers by hand
Marmadbir's payment flow doesn't actually run on Stripe — it runs on Tranzilla, for reasons specific to that business — but the outcome is exactly what a Stripe integration is built to deliver: jobs broadcast, workers apply, payment claimed race-safe so two people can never take the same job, client confirmed automatically. Zero payment race conditions, zero manual reconciliation.

payment race conditions
Yes — tiered plans, free trials, upgrades and downgrades with proration, and cancellations that take effect at the right time rather than cutting someone off mid-period. We wire the subscription status straight into your CRM so your team can see it without logging into Stripe.
A webhook is Stripe telling your system the moment something happens — a payment succeeds, a subscription renews, a card fails — so your CRM, your database and your customer's access all update automatically instead of you finding out when they complain. We verify every webhook signature properly, which a lot of quick integrations skip, so nobody can fake a payment event.
Refunds get issued through Stripe and reflected back into your own records automatically — access revoked or adjusted, the customer notified, nobody manually updating a spreadsheet. Receipts go out the moment a payment succeeds, formatted the way you want rather than Stripe's generic default.
A straightforward Stripe setup — checkout, one payment type, webhooks wired to your CRM — starts at £750, fixed price. Subscriptions, multiple products or a payout and marketplace structure are quoted after a short call, always fixed.
Stripe is what we recommend for most UK businesses starting fresh — it's well documented and the webhooks are reliable. That said, we've built payment automation on other processors too: Marmadbir's field-service platform runs on Tranzilla rather than Stripe, for reasons specific to that business, and the same principles — payments claimed race-safe, zero double-charging, everything confirmed automatically — carried over regardless of which processor sat underneath.
Yes — a successful payment is usually the trigger for several other things: an invoice, a CRM update, a Slack notification, access to a product or booking. We build the payment integration as part of the wider workflow, not as an isolated piece that still needs someone to join the dots by hand.
