Price calculations on the German B2B/B2C market

In Germany it is usual that in an offer as well as an invoice always the individual positions with the unit price net the quantity and the calculated line total in net are represented.
Only at the end the value added tax is calculated and added.

Submitted invoices to the tax office must show these breakdowns.

When we create an offer/invoice with your system, we unfortunately always get a different price when we apply price scales.
And both the tax office and the customer only see the individual prices with two decimal places and add them together.

Here is an example of what the customer would get:

In this case the final price for us is not correct as 1.75 * 50 should be 87.50

We now understand how your system calculates but this is not practical for us.
Therefore we would appreciate a positive message if you could consider such an integration. Maybe it is also enough to define an option in the admin where we can determine the decimal places that will be used everywhere.
