QB Sync Error

Austin B. shared this question ago

Need Answer

Lead 71574585 fails to sync: “already an invoice in QBO linked to this lead.” The QBO invoice has applied payments so it cannot be deleted and recreated. Please re-link the lead to the existing QBO invoice so it resumes updating. Integration is otherwise syncing normally.

Are you seeing this error on QBO?

No, QuickBooks is not showing any error. QBO holds the invoice fine and returns it normally; the failure only appears in IO's sync log.

QBO-side details:

- Invoice internal Id 946, number 71574585, customer Brittany Ly.

- Last modified 2026-08-10 and unchanged since. We have not edited the invoice or its payments in QuickBooks.

- It has 3 applied payments totaling $1,232.03, which is why it cannot be deleted and recreated.

- Its QBO total ($1,233.42) is stale. The IO lead total is now $1,009.19 after edits made on 08/13 that never synced.

The fix we need is for IO to re-point this lead's link to the existing QBO invoice (Id 946) so it resumes updating. Please re-link on your side and let me know when it's set. I'll re-save the lead and confirm the next sync lands.
