- The account must already exist in your DATEV chart of accounts. Ask your tax consultant for the correct account number if needed

- If you use reimbursements, make sure the relevant Pocket Kassenbuch is already available in DATEV Unternehmen online
- Custom booking text (Buchungstext)
- Select the expense information you want to appear in the booking text sent to DATEV
- Arrange the selected fields in the order in which you want them to appear
- This determines the information shown on each expense in DATEV, so you can align the booking text with your accounting conventions

Tags in Pleo reflect Kostenstellen / cost centres (KOST1 and KOST2) in DATEV.
- In the Pleo, go to Settings

- Category groups have automatically populated - edit them by clicking on the title Create categories under each category group
For example, under a "Marketing" category group, categories could be "Facebook" and "Google." - Assign a tax code to a specific category so that any future expenses under that category are automatically assigned the relevant tax percentage
