# Connecting Payhawk to DUO

Payhawk supports direct integration to DATEV Cloud Service, providing you with the flexibility to effortlessly export and sync your expenses between the two systems. By connecting to your DATEV account, you allow Payhawk to [export expenses directly into your DATEV import folder](/help/finding-exported-expenses-and-payments-in-duo).

For more information on what information Payhawk and DATEV exchange, see the article about [exported data between DATEV Unternehmen Online (DUO) and Payhawk](/help/overview-of-shared-data-with-duo).

## Initial interaction between Payhawk and DUO

When connecting Payhawk to DUO, note the following:

- Payhawk creates the BU7, BU8, and BU9 VAT rates. To add other VAT rates, see the article on creating [VAT rates by using DATEV BU codes](/help/adding-vat-rates-with-datev-bu-codes).
- DATEV does not allow you to directly pull your **KOST1** and **KOST2** categories. Therefore, to start exporting the expenses, a Payhawk administrator role has to manually put them in beforehand. For more information, see the articles on [mapping categories](/help/overview-of-shared-data-with-duo) and [pulling **KOST1** and **KOST2** fields](/help/managing-expenses-in-the-portal).

## Prerequisites

Before you start, make sure that your tax advisor has [enabled your **MyDatev** client to use Rechnungsdatenservice 1.0](https://apps.datev.de/help-center/documents/1007329) and [granted you administrator rights](https://apps.datev.de/help-center/documents/1071522).

1. In the [Payhawk Web Portal](https://portal.payhawk.com), open the app switcher in the top-left corner and go to **Settings**, then select **Integrations**.

3. On the next screen, click **Continue**.

7. On the next screen, enter the following information:
  - The **Collective supplier account**. Payhawk uses the collective supplier account for expense and payment postings. You can now assign both types to the supplier's vendor number.
  - The **Payhawk bank account** for the currency that you will use (EUR, GBP, or USD). To upload only the expense (and not the payment) posting for a specific currency to DUO, leave the field empty.
  - The **Cash-in-transit account**, which is used for [mapping deposits to the Payhawk account in DUO](/help/overview-of-shared-data-with-duo).

If you haven't mapped the bank account code, Payhawk won't export your payments to DUO. The same applies to FX fee postings.
8. Click on **Continue**.

9. On the screen that opens, enter the **Accounting code for the ancillary cost of monetary transactions** (ATM withdrawals and FX fees).
10. Click on **Continue**. As a result, your Payhawk account is connected to your account in DUO.
