Configure the invoice number template
To configure the invoice number template, go to the Settings > General > Invoices page.
Here you will find the “Invoice numbering template” field. You can specify both characters and various variables for it:
{C} - invoice counter;
{D} - current day;
{M} - current month;
{Y} - current year.
The {C} variable can be customized.
For example, {C:3} is a three-digit counting counter padded with a "0" on the left.
Combine variables to create intuitive templates!
You can customize not only the invoice number template, but also the invoice numbering. To do this, click on an example of an invoice number and edit the counter in the window that opens.
Setting up an invoice term
Specify the number of days the invoice will be valid from the date of issue. You can change the expiration date manually when creating an invoice. After the expiration date, if the invoice has not been paid, it is considered overdue.
