When you create an invoice, an invoice number is automatically assigned. Halaxy also offers the option to create your own numbering format. This allows you to keep track of your invoices based on your preferences or to keep your invoices consistent if you have imported them from another software product.
-
Click Settings > Payments.
-
Under the Invoice Template Preferences section, click Edit.
-
In the Edit Invoice Template Preferences pop-up, for Invoice number setting, select Custom invoice numbering.
-
Choose the next available invoice number. (Optional: Add a prefix and/or suffix to your invoice number.)
-
Click Save.
You can also set the invoice number on one invoice without changing the numbering format for the rest of your invoices. This is available whether or not you use custom invoice numbering.
Important
Invoice numbers must be unique. You cannot use a number that is already assigned to another invoice.
-
Open the invoice.
-
In the top-right, click the
cogwheel icon to open the invoice settings.
-
In the pop-up, for Invoice Number, click the
pencil icon and enter the invoice prefix, number and/or suffix you want to use.
-
Click Save.
The invoice number is now updated.
Note
Changing the number here applies to this invoice only. Invoices you create afterwards are not affected and continue to follow your existing numbering.
