Stripe billing logic that matches how you actually charge
Usage-based billing, a Connect marketplace with split payouts, proration rules Stripe's docs don't quite cover — plug-and-play plugins stop at the standard checkout flow. We build the custom API layer on top: webhooks that don't drop events, and books that reconcile.
What we build and fix
- ✓Subscription billing with custom proration, usage-based pricing, trials and plan changes Stripe's default flows don't handle out of the box
- ✓Stripe Connect marketplace setups — split payments, platform fees, payout scheduling across multiple connected accounts
- ✓Webhook infrastructure with signature verification, retry queues and idempotency, so a failed event doesn't mean a missed payment
- ✓Reconciliation between Stripe, your CRM and accounting — paid, refunded and disputed states always match
- ✓Migrating billing from another processor into Stripe without breaking active subscriptions

FAQ
We already use Stripe — why do we need custom integration work?
The checkout button is the easy 5%. Usage-based billing, marketplace payouts, proration edge cases and reconciling against your CRM is where off-the-shelf plugins stop and custom API work starts. That's what we scope and build.
Can you fix webhooks that are dropping or duplicating events?
Yes — this is one of the most common fixes we do. Missing signature verification, no retry queue, or no idempotency key are the usual causes, and each is fixable without a full rebuild.
Do you set up Stripe Connect for marketplaces?
Yes — split payments, platform fees and payout schedules across connected accounts, built to match your specific take-rate and payout logic.
Are you GDPR-aware for EU billing data?
Yes — we're based in Belgrade, Central European timezone, and build with EU data-handling requirements in mind by default, not as an afterthought.
