Coupon management

Dear ERP Next users
in our company we buy and sell cement products using a coupon ,like we will pay money for the supplier(factory) then the factory will give us a coupon then when customers wants to buy we will receive the money and give coupons for the customers,is there any one who can suggest me how should i manage this?thanks in advance.

As a workaround, you can create coupon as an Item and then use it similar to an Item.
