What is it for?
It helps review the relationship between an amount before tax, the tax and the total. Use it to support a quote or cross-check a calculation; it does not replace invoice validation or your accountant’s judgment.
How to use it in your workflow
Open the tool, identify whether your starting amount includes tax and enter the amount. Check the rate and the result before adding them to your document. Tax treatment may differ by transaction; confirm what applies to your case.
From a tool to a system
