# DATEV

> Learn how to connect Fynn with DATEV to export invoices, cancellations, journal entries, and debtors.

The DATEV integration facilitates the synchronization of invoices, cancellations, credit notes, journal entries, and debtors between Fynn and DATEV Kanzlei-Rechnungswesen.

## Features

* Export of invoices and cancellations as DATEV document transfer file
* Export of journal entries including prepaid expenses as DATEV posting batch file
* Export of debtors as debtor master data file

## Set up DATEV Integration

To set up the DATEV integration in Fynn, you need the following information:

* DATEV Consultant Number
* DATEV Client Number
* SKR Chart of Accounts

You can obtain the DATEV Consultant Number and Client Number from your tax advisor. The SKR Chart of Accounts is the standard chart of accounts you use in DATEV.

## Configure DATEV Integration

<Steps>
  <Step title="Enter Consultant Number and Client Number">
    Navigate in Fynn to "Settings" > "Accounting" > ["DATEV Basic Settings"](https://app.fynn.eu/settings/accounting/cost-centres) and enter the Consultant Number, Client Number, and G/L Account Length from DATEV.

    <Tip>
      You can find the Consultant Number and Client Number in DATEV. Alternatively, you can also enter fictitious values.
