When you settle a list, the following things will happen:
We use a smart algorithm to calculate who has to pay what to whom
All expenses will be archived and can't be edited anymore. Expenses remain visible under Previous Settlements > Expenses
The settlement including all expenses will also be saved as a PDF
The settlement including PDF will automatically be mailed to all members when the list gets settled
Please note: A settlement can not be reversed. Be sure that all members have entered their expenses correctly before someone settles a list.
After having settled a list, you can keep using the list. You can add new expenses and can settle the list as many times as you want.
