Cash handling at a car wash: floats, counts and keeping money safe

On a Saturday in Kasoa a wash took in roughly GH₵1,600 by 5pm; the box held GH₵1,240. The float had been GH₵150, or was it GH₵200? Two washers had taken money straight from customers and "put it in the box later". The manager had paid a tanker driver GH₵300 and noted it on a scrap of paper, now wet. A regular had paid by MoMo to the manager's personal number because the business phone was flat.

By 7pm nobody was sure of the number. That is the normal state of car wash cash handling at most sites, and it is not caused by dishonest people. It is caused by too many hands, no float rule and no count. The fix is a short set of rules: one cashier, a counted float, MoMo first, a count with two people, bank daily, decide about tips once.

Car wash cash handling rule one: only the cashier takes money

The single rule that matters most: only the cashier takes money. Washers do not. If a customer tries to hand GH₵50 to the boy who dried his car, the boy points to the cashier. After a week it is simply how the wash works.

This closes the biggest gap at once. Money that passes through a washer's hand on the way to the box sometimes does not complete the journey, not always through dishonesty but because he was handed the next car's keys, the note went into his pocket, and by evening he genuinely does not remember. It also removes the "side wash", where a car is washed, paid for in cash to a washer and never recorded.

The float: a fixed number, counted twice

The float is the cash the cashier starts the day with for change. Pick a fixed amount: GH₵200 in small notes and coins, say, though the right figure varies with your prices and how much of your trade is cashless. Count it in the morning, write it on the day's sheet, and have the manager initial it.

Nothing is paid out of the float. Not the tanker, not lunch, not a washer's advance. If the business must pay something in cash during the day, the cashier writes a payout slip with the amount, who was paid and what for, the manager signs it, and the slip sits in the box in place of the money. That humble slip turns "I think I paid the tanker from the box" into a number you can add up.

MoMo as the default, not the exception

Mobile money arrives with a timestamp and a sender's number, into a wallet the washer cannot reach. So make it the default: a merchant number on a board at the entrance and at the counter, and the cashier asking "MoMo or cash?" in that order.

Use a merchant account, not a personal wallet, and never let a manager take payments to his own number "because the business phone is off". That one habit turns a clean record into a guess. Confirm each payment on the business phone before the keys go back; a screenshot from the customer's phone is not a payment. Merchant accounts, charges and daily matching are covered in taking mobile money at your car wash.

The evening count: two people, one sheet

At close, the cashier and the manager count together. Cash in the box, minus the float, plus payout slips, plus the MoMo total from the merchant app, compared against the day's record of cars and prices. Both sign the sheet. The float goes back in an envelope for tomorrow, counted again.

If the numbers match, it takes ten minutes. If they do not, the difference is found while the day is fresh: a car not written down, a payment to the wrong number, a slip not written. The record of cars is what makes this possible; see why you should record every car you wash. Pay washers after the count, against the number of cars on the sheet. Then the takings leave the wash.

Banking daily, or at least getting the cash out

Cash that sleeps at the wash is cash at risk, from a break-in or simply the temptation of a full box behind a padlock. Bank it the same evening or the next morning. If the bank is far, depositing the day's cash through a MoMo agent into the business wallet gets it off the premises; the agent's charge is small compared with a loss.

Where the manager banks it, the deposit slip or the MoMo transaction goes into the box in place of the money and is checked against the sheet.

Tips: decide once, write it down

Tips cause more quarrels than wages. A customer hands GH₵10 to the washer who did his SUV; the other washer, who did the pre-rinse, sees it. Decide the rule once, tell everyone, and keep it. The common choices are that the washer who was assigned the car keeps his tip, or that all tips go into a jar and are split equally each evening or each week.

Pooling is fairer when work is shared; keeping tips rewards the washer the customer noticed. Either works as long as everyone knows which it is. Tips are not takings and never go in the box. The wider question of how washers are paid is in paying car washers: commission, daily wage or both.

Tomorrow morning: count the float, write it down, put the MoMo board at the gate, and tell the washers that from today only the cashier takes money.
