Sales tax (VAT, GST) due on a transaction on an item basis VS an invoice basis.

Keywords: Sales tax (VAT, GST) due on a transaction on an item basis VS an invoice basis.

There are two "grouping" calculation methods:

  • Tax due on a transaction on an item basis

  • Tax due on a transaction on an invoice basis

These methods may give different results, e.g.:

round(2.244 + 2.244) != round(2.244) + round(2.244);

4.49 != 4.48;

By default Beigesoft™ EIS uses the "item basis" method. You can switch it in the "Accounting settings" and a "Tax destination".

Example of two identical invoices for the both methods.

The system's "item basis" method is "On", so just add a new invoice with two services for 55.67USD each with tax 11%:
