Use the Bill Printing feature to print the bill before the payment. This is useful if the bill is still subject to evolve and is thus not the definitive ticket.
Configure Bill Printing
To activate Bill Printing, go to :menuselection:`Point of Sale --> Configuration --> Point of sale` and select your PoS interface.
Under the Bills & Receipts category, you will find Bill Printing option.
Split a Bill
On your PoS interface, you now have a Bill button.
When you use it, you can then print the bill.
