Format restrictions relevant for Business NXT

The following Business NXT options are not covered when sending electronic invoices in the PEPPOL BIS 3.0 format:
Batch invoicing
While it is technically possible to send batch invoices electronically, with or without grouping by order, the content will look the same as a regular invoice. The invoice will only be able to reference a single order (and only if the Order reference is set, see the Invoice - document information section).
Note:
Sending a batch invoice combining net and gross orders will not pass the PEPPOL BIS 3.0 format validation.
Gross order invoicing
All amounts in the electronic invoices are net, except for the total values. This means that all prices and amounts must be converted to net values, which may in some situations cause rounding problems when comparing line amounts with the totals. If possible, invoice with net amounts when sending electronic invoices.
Special tax calculated after total discount
Currently, all special tax calculation is supported except when special tax is calculated after total discount has been applied.
