After successfully saving the numbering formula, you can create an Invoice. If you use "nr" in the formula, Amberlo will number Invoices sequentially from the first number:

If you need the Invoices' numbering to start not from the first number, simply change the number manually to the desired one when creating the Invoice: 

Invoices numbering formula3


After saving this Invoice, Amberlo will remember this number as the last number used and will enter the following number when creating the new Invoice:
