Can anyone help me with defining a fixed amount tax (not in percentage)
Price : 100 $
Tax : 12 $ ==> this tax is fixed for all invoice (12 $)
Total : 112 $
Hey there, thanks for posting! Taxes can only be set using percentages, so if required you would need to calculate the appropriate percentage and apply the tax.
Can youtell us a little bit more about what kinds of things you would use a function like this for?
