## Official rule text

An Invoice shall have the Amount due for payment (BT-115).

## Why did my invoice fail BR-15?

Every invoice must state the Amount due for payment (BT-115), the net amount the buyer actually has to pay after any prepaid amounts (BT-113) and rounding (BT-114). It is derived as Invoice total with VAT (BT-112) minus Paid amount plus Rounding amount. It is mandatory so the recipient knows exactly how much to remit.

## Common causes

- The cbc:PayableAmount element inside cac:LegalMonetaryTotal is omitted.
- The system placed the due amount in the wrong element (e.g. PrepaidAmount) instead of PayableAmount.
- PayableAmount is present but empty or missing its currencyID attribute.

## How do I fix it?

```
<cac:LegalMonetaryTotal>
  <cbc:TaxInclusiveAmount currencyID="EUR">122.00</cbc:TaxInclusiveAmount>
  <cbc:PayableAmount currencyID="EUR">122.00</cbc:PayableAmount>
</cac:LegalMonetaryTotal>
```
