What is a prefix?

A prefix appears before the document number. For example, if your invoice prefix is SI- and the invoice number is 100, Sage displays it as SI-100.

You'll see these numbers throughout Sage Accounting, including transaction lists, reports, statements and customer documents. Your customer also sees them on any documents you send.

1. Go to Settings and select Business Settings.
2. Select Document preferences.
3. Go to the Prefixes and numbering section.
4. Enter your preferred prefix for the relevant document type.
   
   NOTE:

   Your prefix can be up to six characters, with a mixture of letters, numbers and special characters.

5. Select Save.
