We have a demo setup where taxes come from item categories. So we have mixed vat. In this case would be great to hide somehow Rate field on sales invoice’s Sales Taxes and Charges section, because its a bit misleading.

Hi
You can hide this field,

Click on the arrow next to it.

Uncheck Mandatory and In List View and check hidden option.
