# Invoices

The invoice settings allow you to specify a prefix for the invoice number as well as then next number in the sequence. As invoices are generated, Bunny will automatically increment the sequence number while ensuring that there are no gaps.

### Invoice templates

There are times when you may need to provide additional information on an invoice based on the customer's location or industry. For example, in Europe you want to include the customer's VAT number on the invoice. Or maybe you want to ensure the purchase order number is included to ensure a smooth payment process. Invoice templates allow you to easily do this.

Invoice templates can also affect how quotes are accepted by the customer. For example, if PO number or Tax number are required on the invoice template, the user *must* provide the information when accepting the quote in the customer portal.

When an account is created, it is automatically assigned the default invoice template. You can also create [workflows](/guide/tour/workflows.md) that auto-assign invoice templates based on account type, industry or country, for example.

#### Invoice footer

The footer will be printed at the bottom of the invoice after the totals.

#### Bank details

Bank details can be used to show details about how wire transfer are made.
