This document discusses the results and ROI of loyalty programs for restaurants based on real case studies. It provides examples of how loyalty programs can increase enrollments, ticket averages, customer frequency, and convert new customers into regulars. One case study found loyalty program enrollments were 3.38x higher than an email-only program. Loyalty customers also had higher ticket averages of $2.14 more than non-loyalty customers. Additional case studies found loyalty programs increased the likelihood of new customers returning multiple times and increased the number of transactions per customer. The document estimates the total monthly ROI of a loyalty program could be $6,632 or more after accounting for increased sales and reduced marketing costs.
