To set up automatic payment reminders:

1. Go to Settings → "Facturen en offertes"
2. Turn on the reminder toggle ("Te laat? Automatisch een herinnering sturen")
3. Changes save automatically

When an invoice is a few days past its due date, MyCompanyDesk automatically sends a friendly reminder, and repeats it every week until the invoice is paid. The reminder emails use fixed system templates; the text cannot be edited.

Tip: Need to nudge a customer right now? You can also send a manual reminder from the invoice.
