Hmm, that does sound interesting. Is this something that other sites can use to create and track promotions, or something users can use to generate coupons? I'm not sure how these things work...
I thought it would be simpler to just have users (let's call them vendors to distinguish from customers) manually track their redeemed coupons by entering their active coupon codes in the site. The original intent was for brick and mortars (traditionally old fashioned when it comes to these things) to have some help with basic marketing ROI.
Of course to expand the functionality to websites, there would have to be an automatic way for the coupons to be 'redeemed'. The basic flow I have so far is:
1. User creates new coupon (give it a name and description)
1a. App generates unique code for coupon and stores the coupon information in a database
1b. (external to app) User uses coupon code to create coupons to be distributed through whatever channels are appropriate (mailings, website, emails, etc.)
2. User received coupon from customer and manually records a redemption (based on the unique code)
2a. App records redemption count to DB
3. App displays statistics of coupon redemption (how many, when, maybe other attributes)
