Payments and billing
Checkout, subscriptions, refunds and invoices. Money events land in your database once, never twice.
Most products end up with a billing tool, a CRM and a warehouse that disagree. Someone then fixes it by hand every week. We wire them together instead. One senior team designs the contract, builds it and keeps it alive.
These are the six jobs that come up most. Your stack will look different. The method below does not change with it.
Checkout, subscriptions, refunds and invoices. Money events land in your database once, never twice.
Signups, trials and plan changes reach the sales team as they happen. No nightly export, no copy and paste.
Stock, orders and accounting systems. Often older, often strict. We read the docs and work to them.
One event schema across product, ads and email. That is what makes a funnel report trustworthy.
Single sign-on, roles and audit trails. Enterprise buyers ask for this early. We build it in.
Versioned endpoints, real docs and keys your customers can rotate. A product other teams can build on.
Integration work rarely arrives alone. It usually sits next to a product build or a web platform we are already shipping.
Five stages, always in this order. You know which one you are in and what lands at the end of it.
We list every system, every field and every owner. You get one diagram that fits on a screen.
We agree the payload shape before any code. Fields, types and errors, written down and signed off.
Small, boring services with retries and clear logs. Each one ships behind a flag you can switch off.
We replay real traffic in a sandbox. Bad payloads, timeouts and duplicates all get a test.
Alerts go to a channel your team reads. A failed sync is a message, not a mystery ticket.
Picking the wrong transport is the usual cause of a fragile sync. Here is how we choose between the three, side by side.
The same event twice leaves one row. Retries are safe, so a flaky network stays a non-event.
Keys live in your vault, not in our repo. Access is handed over on day one and revocable.
Every endpoint ships with an example call and an example error. New engineers read it, not us.
| Trait | API call | Webhook | Batch |
|---|---|---|---|
| Best for | Live reads and writes | Events you must react to | Bulk history and reports |
| Timing | On request | On change | On a schedule |
| Failure mode | Timeout, retried | Replay from a queue | Rerun the window |
| You see | Request logs | Delivery log | Run report |
We check for a file drop, a database view or a partner endpoint first. If nothing exists, we say so and price the workaround honestly.
Yes. We follow your review rules and your branch model. The work merges into your repo, not into ours.
You do. We hand over docs, keys and dashboards. Many teams keep us on for support, but that is a choice, not a lock-in.
It depends on the vendor and the data. We give a range after the mapping stage, before you commit to a budget.
Every connection we ship is covered by our testing work and can stay under long-term support once it is live.
Name the tools and the data that has to move. We reply with a mapping plan, a budget range and the engineer who would own it.
