Our Country collect the tax before the discount have the GST 5% and QST 9,975%
On an invoice $ 15 GST and $ 0.75 and the QST $ 1.50 When I put 5% off The GST becomes $ 0.71 and the QST $ 1.42 I want the tax to stay the same
My next question is can you put 2 service charge for the same item
Calculations are ticket level so apply to ticket total not orders/items.
Tax if setup properly as a tax is mapped by items in the tax template.
As for discount change the include tax option to reflect before/after tax.
However would you not want tax to be reduced taking into account discount else your paying tax on more sales than you actually made…
