E-invoice error explained

BR-CO-13: Invoice total without VAT does not match

The invoice net total (BT-109) must follow from the lines: sum of lines minus document-level allowances plus document-level charges.

What the rule checks

The invoice net total (BT-109) must follow from the lines: sum of lines minus document-level allowances plus document-level charges. If a discount or freight is included in the total, it must also be in the file as its own allowance or charge.

Official rule text

Invoice total amount without VAT (BT-109) = Σ Invoice line net amount (BT-131) – Sum of allowances on document level (BT-107) + Sum of charges on document level (BT-108).

Source: KoSIT configuration XRechnung 3.0.2 (31 Jan 2026).

Typical causes

  • An invoice-wide discount is included in the total but missing as an allowance (BG-20).
  • Freight or packaging is included in the total but missing as a charge (BG-21).
  • A discount appears twice, once as a negative line and once as an allowance.
  • Rounding: the total was built from unrounded values.

How to fix it

Write each document-level discount as ram:SpecifiedTradeAllowanceCharge with ram:ChargeIndicator false, and each charge with true. Set ram:AllowanceTotalAmount (BT-107) and ram:ChargeTotalAmount (BT-108) to their sums and ram:TaxBasisTotalAmount (BT-109) to BT-106 – BT-107 + BT-108.

Example

Wrong (CII)

<ram:SpecifiedTradeSettlementHeaderMonetarySummation>
  <ram:LineTotalAmount>1000.00</ram:LineTotalAmount>
  <ram:TaxBasisTotalAmount>950.00</ram:TaxBasisTotalAmount>
  <!-- 50.00 discount, but no allowance and no AllowanceTotalAmount -->
</ram:SpecifiedTradeSettlementHeaderMonetarySummation>

Right (CII)

<ram:SpecifiedTradeSettlementHeaderMonetarySummation>
  <ram:LineTotalAmount>1000.00</ram:LineTotalAmount>
  <ram:ChargeTotalAmount>0.00</ram:ChargeTotalAmount>
  <ram:AllowanceTotalAmount>50.00</ram:AllowanceTotalAmount>
  <ram:TaxBasisTotalAmount>950.00</ram:TaxBasisTotalAmount>
  <ram:TaxTotalAmount currencyID="EUR">180.50</ram:TaxTotalAmount>
  <ram:GrandTotalAmount>1130.50</ram:GrandTotalAmount>
  <ram:TotalPrepaidAmount>0.00</ram:TotalPrepaidAmount>
  <ram:DuePayableAmount>1130.50</ram:DuePayableAmount>
</ram:SpecifiedTradeSettlementHeaderMonetarySummation>

In Dynamics 365, Business Central and Finance

Sales / Project Operations: Sales and Project Operations have no e-invoice output out of the box. In the WBS Invoice Accelerator for Dynamics 365 the Accelerator computes every total of the e-invoice from the lines it writes to the file. If this rule appears for a file from the Accelerator, send the whole message to WBS. An invoice-wide discount is written as a document-level allowance.
