Case Study: National Quick‑Service Restaurant Chain achieves 7.4–17.2% sales lift and $2.1M fraud prevention with Fishbowl

Measuring Sales Lift from Groupon Promotions

A national quick-service restaurant chain facing a fast-approaching Groupon promotion wanted to quantify its impact on eClub members’ average check size and visit frequency and determine the promotion’s incrementality when distributed through a third party. They needed fast, individual-level tracking across 700+ locations to match redemptions to members and isolate the offer’s true effect.

Fishbowl deployed Promotions Manager in three weeks, issuing trackable codes and using Guest Analytics to match redemptions to member histories and identify natural test and control groups. Analysis found a baseline eClub annual spend of $29.89, with existing members averaging $32.11 and new Groupon-acquired members $35.50—a 7.4% and 17.2% lift, respectively—driven largely by a 31.8% increase in annual visits. Promotions Manager also blocked 180,465 fraudulent redemptions, avoiding an estimated $2,111,441 in fraud.
