A bar is where loyalty pays back fastest: low ticket, very frequent visit, and a customer who walks past your door, and the one opposite, almost daily. The fight is not about selling more in one visit, it is about being the door they pick.
The model that fits: stamps
With a low, repeated ticket, the stamp card is the natural fit. "Nine drinks and the tenth is on us" needs no explaining and gives a visible goal. The paper version gets soaked behind the bar and forged with a cheap stamp; a digital stamp card in Apple Wallet and Google Wallet updates itself and never gets lost.
Rule of thumb for a bar: the reward should sit six to eight visits away, which for a regular is two or three weeks.
Five concrete tactics for bars
1. Sign people up while you pour
A QR on the bar top and one line: "the tenth drink is on us, shall I put it on your phone?" They add it while you serve. No forms, no app, no queue.
2. Double stamps on the dead days
Monday to Wednesday, or whichever your quiet run is. You pay in product you were going to be able to serve anyway, and you do not discount the night that already fills itself.
3. Own the after-work hour
The group that comes at seven on a Thursday is worth more than any single customer, because they bring people. A reward that only works for a table of three or more turns one regular into four.
4. Bring back the one who stopped coming
Someone who came three times a week and has not appeared in three weeks has almost certainly found somewhere else. A message with a real reason, the match, the new tapa, the dish of the day, catches them before the new habit sets.
5. Turn the regular into a review
When someone redeems their free drink they are at their best moment with you. That is when to ask for the Google review, not when you hand them the bill.
The typical mistake in bars
Treating the programme as a discount. A bar that gives 10% off has taught its regulars to expect 10% off forever, and has bought nothing: they were coming anyway. A stamp card costs you one drink out of ten and buys the nine before it, which is a completely different trade.
The problem in a bar is not the customers, it is the days
A neighbourhood bar rarely has a people problem: it has a distribution problem. Friday is packed and Tuesday is empty, and the profit and loss is decided by the quiet days, because wages and rent run either way.
That changes the goal of the programme. It is not about people coming more in general, it is about moving visits to the days you have room. A loyalty programme beats a discount here, because a discount is also taken by the person who was coming on Friday anyway.
- Double stamps Monday to Wednesday. You pay in product you could serve anyway, not in margin from your good day.
- A reward that can only be redeemed midweek. It turns the prize into a reason to come on a Tuesday.
- A message to weekend regulars with a concrete excuse for a quiet day: the match, the dish of the day, the new tapa.
How to message without burning the list
A bar is the business where it is easiest to overdo it. You have a lot of people's numbers and the temptation to write weekly. Excessive frequency is the leading reason someone stops reading you, and once they ignore you there is no way back.
Three things that help, from the research on reminders (Karlan, McConnell, Mullainathan and Zinman, Getting to the Top of Mind, Management Science, 2016):
- Goal and reward in the same message. "2 more drinks for your free tapa" works better than either half alone.
- Fear or excitement makes no difference. Framing it as a loss or a gain did not change the outcome, so do not spend time on that sentence.
- Nagging does not pay. Additional late reminders added nothing. Two messages and stop.
What to measure in a bar
- Distribution by day of the week. Your main indicator. If Tuesday gains three percentage points, the programme is doing exactly what you asked of it.
- How many come back a second time. A bar has a lot of passing trade and it is worth knowing what share becomes regular.
- Regulars who have vanished. Someone who came three times a week and has been absent three weeks has almost always found somewhere else. That is the alert to catch quickly.
The most expensive mistake in a bar
Keeping your regulars only in the bartender's head. It works until that bartender leaves, or until something new opens next door and you have no way of telling your two hundred customers you exist. A bar with no customer list of its own has no cushion: it depends entirely on people walking past and fancying it.
One practical detail that gets forgotten: a card in the phone's wallet, besides holding stamps, makes your bar appear on the customer's lock screen when they walk nearby. On a street with five bars, being the one that appears is half the battle.
