There is no single right loyalty programme. There is one that fits how your customers buy, and eight that do not. These are the nine models that actually get used, what each is good at, and how to narrow it down.
1. Stamp card: every visit counts
Each visit adds a stamp; at N stamps, a reward. It needs no explaining and gives a visible goal. Best where the receipt is similar every time and the visit is frequent: coffee shops, bakeries, bars, car washes. Weak where spend varies, because it treats a small purchase and a large one the same.
2. Points programme: spend earns, catalogue redeems
Each unit spent adds points, redeemable against a catalogue you define. Fair when receipts vary and flexible on reward value. Best for restaurants, clothing shops, opticians and pharmacies. It needs a well priced catalogue, or the first reward feels out of reach.
3. Tiers: the customer moves up
Customers climb categories as they spend or visit, and each level unlocks better treatment. What sells here is not the discount, it is the access: early entry to a sale, having a size held back, being told first. Cheap to give and perceived as valuable. Strong in fashion and beauty.
4. Cashback: part of the spend comes back
A percentage returns as store credit. Easy to understand and easy to over-give. It works when the margin supports it and the credit buys a second visit rather than discounting the first.
5. Subscription club: paying to belong
The customer pays a recurring fee for ongoing advantages. Powerful because it changes the default: once someone pays to belong, going elsewhere feels like a loss. Demanding to design, because the perceived value has to beat the fee every single month.
6. Referral programme: customers bring customers
The existing customer gets something for bringing someone new, who also gets something. Schmitt, Skiera and Van den Bulte (Referral Programs and Customer Value, Journal of Marketing, 2011) followed around 10,000 bank customers for nearly three years and found referred customers were worth at least 16% more, with better retention that persisted over time.
The practical reading is that referral is not just a cheap acquisition channel, it is one that brings people who stay longer. That justifies paying more for it than for cold acquisition. Usual caveat: German retail banking, so the mechanism transfers better than the exact number.
7. Gamification: turning loyalty into a game
This is where the commercial noise is loudest. Figures like "22% more retention" circulate from gamification vendors with no study behind them. What the academic literature supports is more modest and more useful:
- The effect is not linear. More game is not proportionally better, and past a point motivation drops.
- Formats differ. A recurring short-cycle challenge builds more habit than a one-off prize draw, because repetition is what creates the routine.
- It can backfire when used to paper over a service failure. A spinning wheel does not fix a badly made coffee.
Treat the game as a delivery format, not as the strategy itself.
8. Emotional loyalty: rewarding the bond
Recognition rather than transaction: remembering the usual order, a birthday note, a small gift nobody earned. The mechanism is reciprocity and it is well established in social psychology. What is not established is how much it returns in a neighbourhood bar, so the mechanism can be explained and the number should not be promised.
9. Coalition: several businesses, one programme
A shared programme across a street, a market or a shopping centre. Attractive on paper. The hard part is never the technology, it is agreeing who pays for each reward and who owns the customer data.
Two decisions worth more than the model
How much progress you give away at the start
Nunes and Drèze (The Endowed Progress Effect, Journal of Consumer Research, 2006) handed out 300 cards at a car wash. Some needed 8 stamps from zero; others needed 10 but arrived with 2 already placed. Same real effort, different completion: 19% against 34%.
This cuts across every model. In stamps it means giving the first one away. In points, welcome balance. In tiers, not starting everyone at the bottom. It is the cheapest lever on this page, because it costs no product: it costs moving the starting line.
How often you talk to the customer
The model decides how you reward. Whether the programme survives depends on whether the customer remembers it exists. Karlan and colleagues (Getting to the Top of Mind, Management Science, 2016) found the reminders that work are those naming the goal and the reward together, and that additional late reminders add nothing at all.
Three mistakes that sink any model
- Reward too far away. If it takes two months of visits to reach the first reward, most people quit first. With points this hides behind a big number: a catalogue starting at 2,000 points is a twenty stamp card in disguise.
- Rules that change. Cutting the earn rate or raising a reward price midway reads as moving the goalposts, and it is the fastest way to make people stop checking their balance.
- Setting it up and forgetting it. A programme with no communication is a dead mechanic. What creates repeat business is rewarding and reminding together.
Which model fits which business
- Coffee shop, bakery, newsagent: stamps.
- Bar: stamps, with the real lever being the quiet days.
- Restaurant: points, because a set lunch and a dinner for six cannot be worth the same.
- Hair salon and beauty: points or tiers.
- Clothing shop: points with a season, or tiers if you have people who repeat.
- Gym and classes: neither. Reward attendance, which is what predicts renewal.
- Pharmacy and optician: points, being careful not to reward anything prescription-related.
- Several businesses on one street: coalition, knowing the hard part is the agreement, not the software.
