When a record fails to sync with [QuickBooks Desktop](/integrations/accounting/quickbooks-desktop/overview) — a [customer](https://www.fieldpulse.com/features/customer-management), invoice, [payment](https://www.fieldpulse.com/features/fieldpulse-payments), or item — you can use the in-app troubleshooting tool to see the exact error and fix it. Select the **Failed Sync** button next to the record to open a page listing every sync error for that record. This page is the full error reference: find your error message below and follow the matching action. Failed Sync button opening the QuickBooks Sync Failed dialog with the error and its fix ## Overview Every failed record in FieldPulse carries a **Failed Sync** button that opens a dedicated page listing all sync errors for that record. Most errors come down to a field that's too long, a special character QuickBooks rejects, a duplicate name, a closed accounting period, or a referenced record that isn't synced yet. Fix the cause named in the error and the record re-syncs. To see which records failed and when the sync last ran, use the **Statistic** page covered in [How to Manage QuickBooks Desktop After Syncing](/integrations/accounting/quickbooks-desktop/post-sync). ## Common issues ### Field length limits QuickBooks Desktop enforces a maximum length on many fields.
