Tax Settings

Hi:

I don't have the answer, but rather a suggestion.  Have the site calculate the sales tax and instantly add a refund/credit to the invoice with the wording:  We cover your sales tax.
That makes the company look good in the eye of the shopper and the site still calculates and reports the sales tax as usual.  I'm not an PC programmer, but this sounds easier from my programming background.  I don't think it involves much coding.

Why not.  You are not refunding the tax or change the tax amount calculated, you are simply giving automatically a reduction to the total amount owed to you.  With other words the credit is applied to the invoice, but not the tax calculated amount.  It will show the taxes calculated on the invoice and the back office.  From a logic point all that needs to be added to the code is:
Calculate tax
report tax to the back end
print tax onto the invoice
add a courtesy credit line to the invoice
subtract from the invoice
do not subtract from the tax back end

or shorter:
Calculate tax
report tax to the back end
do not print tax onto the invoice
do not add tax to the invoice
do not subtract from the tax back end
 
Any PC programmer can apply either logic to your site.  I bet Greg Dinger can help you quickly with this.

As I've said it sounds like just a few lines of code to me. 

Exactly,looks like this isn't straight way to get this done except taking this process offline and then calculate the taxes. Prolly a job that runs every night and does the calulatuons and stores it in the database.
If there is an easier way please share
