Reward programs, loyalty programs, and referral programs are all different types of customer incentive programs. Here is the key difference between these programs: 1. Reward programs aim to encourage repeat purchases and customer engagement by offering rewards or incentives based on specific actions or spending thresholds. 2. Loyalty programs focus on creating a loyal customer base by offering exclusive benefits for loyal customers. 3. Referral programs leverage existing customers to acquire new ones by incentivizing them to refer their friends, family, or colleagues to the store.
