Coupon on parts ticket coding

[LOWAIRD1964]

Curious how your system is set up for giving out coupons/discounts. We are on Reynolds and Reynolds. It seems that we are set up so when I do a coupon under misc on the invoice that it is pulling from 33f our freight account and then when I get the credit we are just washing that account. Is this the correct way for it to be set up or is there a better way? I have one of these shop/click/drives I am doing now and if I take the $100 coupon off im afraid it is affecting my gross? Kind of confused on this and im not sure if I just thinking to hard on it or what? When billing part I leave it be at full price then take the coupon/disc off after I hit enter on second page of ticket/invoice. If someone can share how they currently have it set up that would be great. Thanks!

we do coupons and price matching on the MISC in a negative account but I think we have it credit I think 65 advertising account. Shouldn't effect gross profit at all
