Invoices must have an invoice number. You are free to use your own numbering system, as long as the numbering is consecutive. There should be no gaps between the numbers.
In InformerOnline, consecutive invoice numbers are generated automatically. You can choose one of the standard numbering sequences provided by InformerOnline or set up an alternative numbering system.
Setting up an invoice number
Standard invoice numbers
By default, InformerOnline invoice numbers start with the current year, followed by a prefix ('-') and then a four-digit number, starting with "0001." The first invoice number issued for the year 2024 would be "2024-0001."
To select a different standard invoice numbering sequence, follow the steps below:
Navigate to Settings in the left-hand menu;
Choose Sales settings;
Review, select, and adjust as desired;
Number format: Choose the format for your numbering:
[year][prefix][serial number];
[year][serial number];
[prefix][serial number];
[serial number];
[serial number][prefix];
[serial number][year];
Number prefix: If you selected a prefix in the Number format, enter the prefix you want to use in your numbering;
Serial number: Enter the sequence number you want to use for your numbering;
Reset number series at the beginning of the new financial year: Enable this to reset the sequence number at the beginning of the year. The numbering will start again from 0001 in the new year;
