## Official rule text

The allowed maximum number of decimals for the Invoice line charge amount (BT-141) is 2.

## Why did my invoice fail BR-DEC-27?

An Invoice line charge amount (BT-141), a surcharge applied within a single invoice line, may carry at most two decimal places. This keeps line-level charges at currency precision so they add cleanly to the line net amount.

## Common causes

- Computing a percentage-based charge as a float without rounding
- Prorating a shared charge across lines and emitting the raw result
- Outputting more decimals than the currency minor unit permits

## How do I fix it?

```
Round to 2 decimals: <cac:AllowanceCharge><cbc:ChargeIndicator>true</cbc:ChargeIndicator><cbc:Amount currencyID="EUR">3.50</cbc:Amount></cac:AllowanceCharge>
```
