Billing that balances.
Payments, subscriptions, marketplaces, and tax on Stripe — built with the webhook discipline that stops accounts going out of sync and money going unaccounted for. Every event handled once, every charge tied back to the books.
What the integration handles
Statement of line items
The webhook you didn't handle is the ticket you'll get.
Stripe makes taking a payment easy. The hard part starts after the charge: Stripe fires an event, your app is supposed to react, and somewhere in that handoff is where billing quietly breaks. The endpoint times out and Stripe retries the same event four times. A subscription upgrade fires an event you never wrote a handler for. A signature check rejects a valid event because of a body-parsing quirk. Each gap turns into the same support thread — "I paid, why hasn't my account updated?" We treat webhooks as the spine of the integration: verify, handle once, update, and reconcile, so the answer to that question is always already correct.
Event
Stripe emits a signed event the moment money or state changes.
Verify signature
We check the signing secret before trusting a single byte.
Idempotent handler
Keyed on the event ID, so a redelivery is recognised and ignored.
Update
The customer's record, access, and books change exactly once.
Reconcile
A sweep compares Stripe's truth to yours and clears any drift.
What we build
Four capabilities that cover most of what Stripe is asked to do in production.
One-time & subscription payments
Payment Intents for single charges, full Billing for plans, trials, and usage-based pricing. The flow handles upgrades, downgrades, proration, and failed-payment dunning — not just the happy-path first charge.
Marketplace payments with Stripe Connect
Seller onboarding and KYC, charges split between your platform fee and each payout, transfer schedules, and the failed-transfer and reversal cases. Express, Standard, or Custom accounts — whichever matches how you actually pay people.
Stripe Tax
VAT, GST, and sales tax calculated from where the customer is and what they're buying, applied to checkout and invoices, and kept current as rates change. The filing-time reporting is wired in too, so finance isn't reverse-engineering it later.
Reconciliation reports
Payouts tied to bank deposits, gross charges netted against refunds, disputes, and fees, and mismatches flagged for a human. Month-end becomes reading a clean statement instead of an archaeology project across three tools.
Every event handled once.
From the charge to the payout to the line in your ledger — nothing lands twice, nothing goes missing.
Tying Stripe to the books, line by line.
Stripe knows what happened; your accounting needs to agree. We reconcile the two so a payout that hits the bank maps to the exact charges, refunds, fees, and disputes behind it. When the numbers don't line up, you get a flag worth investigating — not a silent gap discovered three weeks later.
Audit the flow
Where money enters, which events you handle today, and where accounts drift.
Design the contract
Event handlers, idempotency keys, and the tax and payout rules — decided first.
Build the discipline
Verified, idempotent webhooks and the payment, subscription, or Connect flow.
Backfill & reconcile
Replay missed events, reconcile history, and prove the numbers tie out.
Operate & alert
An operator view and alerts so a failed webhook is caught before a customer is.
Questions teams ask first.
Is Stripe out of sync with your app?
Tell us where it hurts — webhooks failing quietly, subscriptions drifting after Stripe events, or growth past simple Checkout. We'll audit the flow and build the payments, Connect, tax, and reconciliation that keep the numbers honest.
