Accounting Webhook Integration

Sync invoices with Xero or other accounting systems through an automation platform.

Advanced6 min readUpdated 2026-08-19

Generate an invoice in AwardLettr, then open your accounting system and key the same line items in again so your books reflect the AR. That is the standard workflow for a lot of solo appraisers, and it is double entry of data you already entered once. Worse, the two systems drift out of sync the first time you change something on one side and forget the other.

A webhook closes that loop. AwardLettr generates the invoice, fires the data to your accounting system, and the invoice exists in both places with the same numbers. If you use external invoice numbers, the accounting system is the source of truth and AwardLettr puts the right number on the PDF. No more reconciliation headaches at month end.

Useful for any appraiser whose accountant or bookkeeper needs the books current in Xero or a similar system. Especially valuable for firms where the volume makes manual reentry impractical.

On QuickBooks Online or Xero?

QuickBooks Online and Xero each have their own direct connection, no automation platform needed. See "Connect QuickBooks Online" or "Connect Xero" below. Once one of those is connected that way, this webhook is not used for invoices.
