Adyen (Payments) and QuickBooks Desktop (Accounting) are commonly run side-by-side. When teams operate both, the question that follows is always how to keep the two in sync without re-entering data twice.
What people typically integrate
- Match incoming payments to invoices automatically
- Reconcile processor fees as separate journal entries
- Push refunds and disputes back into accounting for visibility
- Generate sales tax breakdowns at deposit time
How the integration works
There are usually a few paths to choose from, depending on stack and budget:
- Native integration (one or both vendors offer first-party support)
- rest-api" class="glossary-link text-db-cyan hover:text-db-cyan-dark underline decoration-dotted underline-offset-2" title="Representational State Transfer - an architectural style for building web services....">REST API on one side, file/CSV bridge on the other
- Webhook-driven sync (real-time, event-based)
- Zapier / Make / n8n (low-code, fast to ship, ongoing per-task fees)
- Custom Python / ORM, admin interface, authentication, and 'batter...">Django adapter (full control, no per-task fees, requires engineering)
What flows between the systems
Common records that move back and forth:
- transactions
- payouts
- fees
- refunds
- disputes
Complexity
This integration is typically medium. Both tools have a REST API, so a custom integration is straightforward to build but does require some engineering. Off-the-shelf connectors may also exist.
