Frequently asked questions
When is a customer in default?
Under § 286 BGB, 30 days after the due date and receipt of the invoice at the latest – for consumers only if the invoice points this out. A reminder after the due date also triggers default.
May I charge a reminder fee?
Only your actual costs (postage, material) – usually a few euros. Flat fees for the first reminder are often not allowed.
