Credit note

In the expenses, at some point you have the option to tick a box, step 2 or something? The expense is a credit note. That's how you book a purchase invoice that is a credit note.

Dear, how do you do this if the amount is -17 euro?

You have to tick the box 'is a credit note' and enter the positive amount (so +17 euros in your case). Because the 'is a credit note' box is ticked, Dexxter knows that it is a negative amount and everything is calculated correctly.
