Coupons

If a customer would like to apply a coupon to their order, add "/COUPON" as a line item with the coupon code in the comment field.

Once you've done that, make sure the DC box is checked for all the items the coupon applies to. For example, if the coupon is specifically for steel items make sure that only steel items have the DC box checked. Only one coupon code may be applied to an order, so if they want to use multiple they'll have to make multiple orders.

After that, on page 4 of Sales Order Entry, you can either set the Discount Rate to the percentage off that they get on the checked items or you can input a dollar amount on the Discount Amount line. This will automatically apply that discount to the totals of those items.
