# Syncing suppliers between Payhawk and MS Business Central

Payhawk has launched a set of supplier management functionalities, which enables the exchange of supplier information and details between the Payhawk and MS Business Central systems.

The supplier synching option optimizes an employee's time navigating between the two systems and looking for supplier information when paying bills or performing other related activities.

## Specifics

When synching suppliers between Payhawk and MS Business Central, note the following specifics:

- Payhawk will filter out only the suppliers for the specific MS Business Central subsidiary.
- Payhawk will sync only active suppliers from MS Business Central. Blocked suppliers will be filtered out.
- Payhawk will sync only suppliers with unique names and tax numbers.

If you have suppliers with the same name or tax number, Payhawk will not sync them. These skipped suppliers will appear in the **Sync details** panel with a **Go to MS Business Central** link for you to fix the issue while the **Suppliers** sync shows as **Partially synced**. For more information, see the article on [resolving supplier sync issues between Payhawk and external systems](/help/automating-master-data-sync-between-payhawk-and-your-erp-system).
- Payhawk will sync from MS Business Central only suppliers that have both **Gen. Bus. Posting Group** and **Vendor Posting Group** fields populated. Suppliers with empty posting group values will not be synced to Payhawk.

## Initially synching suppliers between Payhawk and MS Business Central

The initial sync between the Payhawk and MS Business Central systems performs the following:

1. Payhawk imports the list of suppliers from MS Business Central.
2. Payhawk will attempt to map all existing suppliers to the MS Business Central suppliers.
3. Once the mapping finishes, Payhawk will show only the suppliers that are available in MS Business Central.

Payhawk will not update previously classified expenses. If a supplier has been selected for an expense before the initial sync, Payhawk will not update the **Supplier ID** to match the **Vendor ID** in MS Business Central.
