- Invoice numbers can follow a sequential order or a custom format based on the business’s preference.
- Traceable:
- They make it easy to locate specific invoices for reference, auditing, or disputes.
Purpose of an Invoice Number
The invoice number serves multiple purposes in business operations. Here’s why it’s essential:
1. Facilitates Record-Keeping
