Why This Error Matters

Check separator

Use . not , for decimals

Limit decimals

Max 2 for currency amounts

3

No thousands separator

Write 1000.00 not 1,000.00

<cbc:Amount>1.234,56</cbc:Amount>
<!-- GOOD: -->
<cbc:Amount>1234.56</cbc:Amount>

Technical Details

XPath: //cbc:Amount, //cbc:PriceAmount, etc.
