Apron automatically recognises due dates if they are specified in the document.

If a bill lacks a due date and there are no customer or supplier rules set, Apron leaves the due date field empty.

You can apply a default due date rule to all bills (e.g.: 30 days after the issue date). To do so configure this in Settings under Advanced Bookkeeping - Purchases or Sales defaults. Simply click on 'Set due date' and confirm your selection. You can also establish specific rules for individual contacts via Customer and Supplier Rules. Learn more in our article: How do I set up customer/supplier rules?.

For receipts, the due date is set to the issue date unless the document specifies otherwise.
