What it means
The amount of a charge that applies to the whole invoice rather than to one line (BT-99), such as shipping, packaging or an admin fee, has more than two digits after the decimal point. Every digit after the point counts, so 7.504 fails and so does 7.500.
Why it matters
Charges on the whole invoice are added into the invoice totals. An amount with extra decimals cannot be added into totals that are limited to cents, so the file fails validation and is rejected.
How to fix it
Find the extra fee on the whole invoice (software often calls it a document charge, surcharge or shipping cost) and round its amount to two decimals. Then check that the total of charges (BT-108) is still the sum of these charges. Round the number that is exported, not just the one displayed on screen.
The rule as published
The allowed maximum number of decimals for the Document level charge amount (BT-99) is 2. Business terms: BT-99
