# Supplier not synced - a supplier with the same name or tax number already exists

This error message appears in the **Sync details** panel when a supplier is skipped while syncing to your ERP because a supplier with the same name or tax number already exists there. The rest of the sync still completes, and the **Suppliers** row shows **Partially synced**.

## Cause

The supplier being synced has the same name or tax number as an existing supplier in the ERP. Payhawk syncs only suppliers with unique names and tax numbers, so the duplicate record is skipped.

## Solution

1. Open the **Sync details** panel and note the affected suppliers (supplier name, tax number, external ID).
2. Use the **Go to [ERP]** link to open your accounting system.
3. Remove or merge the duplicate, or update its details so each supplier has a unique name and tax number.
4. Return to Payhawk and run the sync again.
