Invoicing has an interface to import reminder data (e.g., from your accounting system).

To import reminder data, open Invoicing, click on Batch Processing, and in the opening dialog, select „Upload Reminder Data…“. Choose the text (.txt) or CSV file (.csv) where your reminder data is stored and click „Open.“

In the next step, you will receive the result of the import process and a list of reminders that have not been sent yet.

After clicking „Send Reminders…“, a final security prompt will appear. Confirm it with „Yes“ to send the reminders.
