## Official rule text

An Invoice shall contain the Buyer name (BT-44).

## Why did my invoice fail BR-07?

The invoice must contain the Buyer name (BT-44), the name of the party to whom the invoice is addressed and who is purchasing the goods or services. It identifies the customer for accounting and delivery. In UBL it is cac:AccountingCustomerParty/cac:Party/cac:PartyName/cbc:Name.

## Common causes

- The Buyer PartyName/Name element is missing.
- The Buyer party block contains only an endpoint or scheme identifier and no name.
- The buyer name was placed under PartyLegalEntity/RegistrationName while PartyName is empty.
- Customer party was omitted or left as a placeholder.

## How do I fix it?
