# Connecting Payhawk to Rillet

Payhawk supports direct integration with Rillet and provides you with the flexibility to effortlessly export and sync your expenses between the two systems.

For more information, go to the article about [exported data between Payhawk and Rillet](/help/overview-of-shared-data-with-rillet#exported-data-fields-to-rillet).

## Initial interaction between Payhawk and Rillet

By connecting to your Rillet subsidiary, you allow Payhawk to perform the following:

- Sync your **Bank accounts**, **Chart of accounts**, **Tax rates**, **Suppliers**, **Custom fields**, **Currencies**, and **Subsidiaries**, and refresh them on a recurring basis.
- Push to Rillet the new suppliers that you create in Payhawk.
- Automatically push expenses and payments in real time.

## Before you begin

To connect the two systems, you need:

- A Payhawk Administrator or IT Administrator role in Payhawk.
- Access to your organization's Rillet account.
- A Rillet API key. To generate one, in Rillet, go to **Org Settings** > **API Access**. The key doesn't expire, so the connection stays active until you revoke the key.
