Car wash packages and monthly memberships: do they work in Ghana?

"A Bolt driver asked me for a monthly price. He wants to wash every day. What do I say?" The owner asking runs a wash near the Takoradi market circle, and her instinct was to refuse, because "every day" sounded like a man planning to wash for free. Her second instinct was that a driver who comes every day is the best customer she has. Both instincts were right, which is why the answer needs some arithmetic.

A car wash membership in Ghana is not the glossy unlimited plan of a tunnel wash in a shopping mall. It is usually a laminated card, a line in a notebook and a handshake. Done badly, it hands your busiest customers a discount they did not need and a reason to argue at the cashier's table every week. This post goes through the forms that work here, the ones that leak, and how to track them with a notebook or a phone.

The three forms you will actually see

The simplest is the stamp card: wash five, the sixth is free, or wash ten and get a full wash for the price of a body wash. It costs you one wash in six, which is about 17 percent off for the customer who completes it, and nothing for the customer who loses the card after three. The prepaid card is the next step: the customer pays in advance for a block of washes, say five saloon body washes for the price of four, and the card is punched or crossed off each visit. You get the cash now, which is useful in a slow month, and the customer gets a discount for trusting you with it.

The monthly membership is the one the Bolt driver wants: a fixed fee for a month, either for a set number of washes (say twelve) or for "unlimited". The set-number plan is a prepaid card with a time limit. The unlimited plan is where the arithmetic matters.

Who a monthly car wash membership is for

Commercial drivers: Uber, Bolt and Yango drivers, taxi drivers, and the owners of small delivery vans. They wash far more often than private owners, they care about speed and price, and they talk to each other on WhatsApp. A plan that suits them is mostly quick body washes early in the morning, with a weekly interior. Winning Uber, Bolt and Yango drivers as regular customers goes into what they want from a wash beyond the price.

A private car owner washing once a week does not need a membership and will rarely buy one; a stamp card is enough.

The arithmetic of "unlimited"

Take a wash charging GH₵30 for a saloon body wash where each wash costs about GH₵20 in commission, water and chemicals. A driver who washes every day of a 26-day working month would pay GH₵780 at list. An unlimited plan at GH₵450 looks like a 40 percent discount to him, and he will buy it. But if he actually washes 26 times, your cost is GH₵520 and you have lost GH₵70 for the privilege of washing his car every day.

Unlimited only works if you cap it in practice (one wash a day, body wash only, weekday mornings) or price it close to what the heaviest user would cost you. A plan of twelve body washes for GH₵300, valid for one month, is safer: the driver saves GH₵60 against list, you earn above cost on every wash, and washes he does not use expire.

Check the numbers against your own cost per wash, which How to price car wash services by vehicle type shows how to work out, before you print any card.

Where memberships leak

Three leaks come up at nearly every wash that has tried this. The first is the shared card: one driver buys the plan and three friends wash on it, especially if the card has no plate on it. Write the plate on the card and the record, and wash only that car. The second is the lost count: nobody is sure whether this is the ninth or the eleventh wash of the month, the driver says ninth, the cashier shrugs, and you give away two. The third is the washer who stamps a card for a friend, or stamps twice.

Tracking that a cashier can keep

For a wash with a handful of members, a notebook page per member works: plate, name, phone, plan, start date, and a row of dated ticks. The cashier, not the washer, makes the tick, and the member can see the page. The daily car record should also mark the car as "member" with no cash taken, so the evening count still balances.

For prepaid and stamp cards, laminate them, write the plate in permanent marker, and keep a duplicate list of cards issued with the date and the amount paid. A card that does not match the list is not honoured. If you later move to recording cars on a phone or computer, plate-based tracking becomes much simpler; Loyalty programmes for car washes that do not cost much compares the options.

Setting the rules in writing

Before you sell the first plan, write five rules on a card and give one to each member: the plate it covers, what is included (body wash only, or with interior once a week), the hours it is valid (weekdays before noon, say, to keep Saturday bays for full-price customers), what happens if the card is lost, and that it expires at the end of the month with no carry-over. The last rule is what makes the arithmetic work.

Then start small. Sell ten plans to ten drivers you already know, run them for two months, count the washes each one actually used, and see whether the fee was right. Adjust the price or the cap, and only then put a sign up.
