Most stamp card abuse is small and friendly: a staff member stamping a mate twice, a group of friends each claiming a stamp for one round, a customer asking for a stamp for a visit they say was missed. Decide which of these you mind, write the rule on the sign, stamp at the till as part of payment, and check your monthly reward count for anything that jumps. A single stamp costs cents, so suspicion and confrontation usually cost more than the leak itself. Act on a pattern, not on a hunch.
What one stamp actually costs
Divide the cost of your reward by the number of stamps on the card. A juice bar that gives a free juice costing $2.30 to make, on an eight-stamp card, gives away about 29 cents with every stamp.
Now size the usual leak. A staff member who adds one extra stamp for a friend twice a week is giving away 58 cents a week, or about $30 over a year. That is not worth a scene. It is worth a clear rule, because a leak with no rule tends to grow, and a rule nobody wrote down cannot be blamed on anyone.
The usual leaks
Extra stamps for friends. Staff are generous with people they like. Usually it is a stamp here and there; occasionally it is every visit.
Staff stamping themselves. Decide one way or the other. Either staff can join and collect stamps on purchases they pay for, stamped by someone else on shift, or staff stay off the card and get a staff discount instead. The second is cleaner and avoids awkward conversations later.
Group orders. One person pays for four juices. Is that four stamps for the payer, or one each for four members? On a per-visit rule, the honest answer is one stamp for each member who is there and buying, on their own number. Write it down.
Catch-up stamps. "I was in on Tuesday and you forgot." For a regular you know, once in a while, give it; a stamp costs cents. If the same person asks every week, it has become a habit, and the rule on the sign does the talking.
Shared numbers. A household may use one mobile for the card. That is usually fine; it is one family's habit, and the card is meant to reward habits. Decide that sharing within a household is allowed and say so.
Accidental double presses. In the rush, a button gets pressed twice. On Counter Club each press is one stamp and there is no undo in the dashboard, but an extra stamp is not lost and a mistaken one can be corrected by email, as what counts as a stamp explains.
Put the rules where everyone can see them
Four short lines under the QR settle most questions before they are asked:
- One stamp per visit, for the person paying for their own order.
- One card per mobile number; a household may share.
- Stamps and rewards cannot be swapped for cash.
- Rewards can be claimed on any visit.
Use your own words and your own rule; if you stamp per item, say so. The point is that the rule is written, the same for everyone, and readable from the queue. When a question comes up, staff can point to the sign rather than make a judgement call about a customer standing in front of them.
Spotting a pattern
Ring every reward through the till as its own line, a $0 item or a discount key labelled for the card. Most tills report sales by staff member, so you can see not only how many rewards went out but on whose shifts.
Know your normal weekly count. A shop that hands over 11 to 13 rewards most weeks should notice a week of 22.
Look at the list for rows that climb faster than any regular could. The Members page shows each member's stamp count and reward codes waiting, though not who pressed or when, as the Members page help sets out. A member who joined a fortnight ago and already has three rewards waiting is either your best customer ever or a pattern.
A worked example: Pippin Press Juice Bar
Pippin Press Juice Bar is a fictional juice bar with an eight-stamp card for a free juice, which sells for $9.50 and costs $2.30 to make. In an ordinary week the till shows 11 to 13 reward lines.
One week it shows 22. The till's report by staff member puts 14 of them on Thursday and Friday afternoons, both worked by the same casual. On the members list, two rows that joined within the past fortnight each show three rewards waiting, which is 24 stamps in two weeks for each of them.
The owner talks to the casual privately at the end of a shift, without accusing anyone. It turns out a group of his friends from uni come in most afternoons. One pays for the round, and he has been stamping every juice to whoever paid, plus the odd extra stamp for being regulars. He thought he was being friendly, and nobody had ever told him otherwise.
The owner clarifies the rule for everyone: one stamp per member per visit, on their own number. The friends are welcome to join individually, and three of them do. The rewards already earned are honoured; arguing over a few juices with customers who did nothing sneaky would cost more than it saves.
The leak had been running at about ten extra rewards a week, or $23 a week in juice. Left alone, that is about $1,196 a year. The next week the till shows 12 reward lines.
Mistakes to avoid
Confronting a customer at the counter. Even when you are right, the queue sees a shop accusing a customer.
Taking stamps back without a word. If something needs correcting, talk to the member first.
Checking receipts or ID for every stamp. It slows the counter and insults the honest majority to stop a few cents leaking.
Leaving the rule unwritten. Staff cannot apply a rule that exists only in the owner's head.
Paying staff per sign-up or per stamp. It rewards exactly the over-stamping you are trying to stop; getting every staff member to offer the card covers better ways to keep them asking.
Ignoring a doubled reward count for months. A jump is easy to see in the first week and hard to undo after a season.
What to do this week
- Work out your cost per stamp: reward cost divided by your target.
- Write four short lines of rules and put them under the QR.
- Decide the staff rule, staff on the card or a staff discount, and tell everyone on the roster.
- Add a reward line to the till if you have not already.
- Note your normal weekly reward count, so a jump stands out the week it happens.
