Change in Summary

In the summary screen when you press on the Tax payable you see all the tax transactions. The problem to my opinion is that the records are per item and not per invoice. This way make a little difficult to check all the records, it would be easier if the list was summarized by invoice

The reason that cannot happen is because tax transactions are by line item, not by invoice. Some invoices may contain more than one tax code, and each must be handled separately. The Summary balances are per account, not per invoice, recording every transaction contributing to the balance of an account. Every account listed is the same way.

If you want per invoice, then use one the tax reports.
