Digital loyalty card for a convenience store

Convenience is the hardest place to run a loyalty programme, for one reason that has nothing to do with technology: a large share of what you sell makes you almost nothing. A flat earn rate across the whole shop takes your reward money out of exactly the lines that can least afford it.

The problem with one rate for the whole shop

Most platforms let you set one number: points per pound. It is simple, and in a shop with one margin it is right. A convenience store does not have one margin. It has a spread, from single figures on some lines to forty per cent and up on others, and a customer spending ten pounds might be handing you two pounds of gross profit or fifty pence depending on what is in the bag.

Give two per cent back on everything and you have given away a percentage of revenue, which is a different and much larger percentage of profit on the thin lines.

25 per cent£2.50£0.208 per cent
40 per cent£4.00£0.205 per cent

Put your own categories against those margins. The row that should stop you is the first one: on your thinnest lines, a reward that reads as two per cent is a third of what you made.

What to do instead

Exclude the categories that cannot carry it. Every serious platform, ours included, lets you name categories that earn nothing. The usual candidates are the ones where your margin is set by somebody else and the customer is buying on price anyway.

Frequency beats basket here too

A convenience store's best customer is the one who walks past two competitors on the way. That is a habit, and habits are moved by small, frequent, certain rewards rather than by a large one a long way off. A reward every fifth or sixth visit, worth a couple of pounds, will do more than a five per cent rate that pays out at Christmas.

What to watch in the first month

One number tells you whether the rules are right: the share of your rewards being earned on your excluded and thin categories. If customers are working out that they can earn on the cheap lines and spend on the good ones, the rules need changing before the habit sets.

The other is redemption. Points that are never spent are a liability sitting on your books, and a programme nobody redeems from is not building loyalty, it is collecting a debt.
