Stop double-entering into QuickBooks

If a sale in your app becomes a manually typed invoice in QuickBooks, someone is copying data, and copies drift. A QuickBooks Online integration pushes the records automatically: a new customer, an invoice, a payment received, all flowing from your system into your books on the schedule you set.

  • Customers created and updated in QuickBooks from your app
  • Invoices and sales receipts pushed automatically
  • Payments and refunds recorded against the right invoice
  • Products and services mapped to your QuickBooks items
  • Sync on a schedule or in near-real-time via webhooks

Mapped to your chart of accounts

Accounting integrations fail when data lands in the wrong place. We map your app's concepts to QuickBooks correctly, income accounts, tax codes, payment methods, classes, so your accountant sees clean books instead of a pile of uncategorized entries.

We handle the matching problem too, making sure a customer in your app links to the right QuickBooks customer instead of creating duplicates.

  • Field and account mapping to your chart of accounts and tax codes
  • Duplicate prevention with reliable customer and record matching
  • Sales tax handled to match your QuickBooks configuration
  • Handling of edits, voids, and after-the-fact refunds
  • A sync log showing what synced, what failed, and why

Built on the official API, safely

We integrate through QuickBooks Online's official API using OAuth, so credentials are handled the approved way and tokens refresh without a manual re-login. The integration runs in the background and flags anything it can't sync for a human to resolve.

  • Official QuickBooks Online API with OAuth, no scraping
  • Token refresh handled automatically
  • Background processing with retries on transient errors
  • Clear error surfacing for records that need human attention
  • Sandbox testing before touching your live company file

Frequently asked questions

QuickBooks Online or Desktop?

Our integrations target QuickBooks Online, which has a modern, supported API built for this. QuickBooks Desktop is possible but works differently and has more constraints. Tell us which you run in the consultation and we'll confirm what's feasible.

Which direction does the data flow?

Most setups push from your app into QuickBooks, invoices, customers, and payments, because your app is where transactions happen and QuickBooks is the ledger. We can also pull data back, like payment status, where it's useful. We map the exact directions to your workflow so nothing loops or double-counts.

What if a record fails to sync?

It's logged and surfaced rather than silently dropped. The integration retries transient failures automatically, and for real problems, a missing account or a mismatched customer, it flags the record with the reason so someone can fix it. Your books stay trustworthy because failures are visible.
