Peppol BIS Billing 3.0.21Sum of Invoice line net amount (BT-106) = Σ Invoice line net amount (BT-131).
In plain English
The invoice total of line net amounts (BT-106) is not the sum of the line net amounts (BT-131). This is usually rounding: each line was rounded differently from the total.
How to fix it
Recompute BT-106 as the sum of the already-rounded line amounts, or let POST /v1/conversions compute every total for you.
