Laundromat bookkeeping: five cost lines and a monthly close

What to take away

What follows is general laundromat business information, not individualized tax, legal, utility, or equipment advice. Your jurisdiction, lease, utility rates, and machine mix decide the specifics. A CPA, a licensed attorney, and your local permitting authority decide what they mean for you.

The five lines that decide the month

A laundromat's cash flow is simpler than most retail. You sell turns. Every turn has a cost you can name.

Rent is the floor the month has to clear. Utilities are the line that surprises owners, because water and sewer are usually billed together and the sewer rate often tracks water volume rather than what actually goes down the drain. Confirm the rate structure with your water utility before you sign a lease.

Setting vend prices from cost per turn

Set vend prices by adding what a turn costs you, not what the store down the street charges. Cost per turn is water and sewer for one cycle, plus gas or electric for the dryer, plus chemicals, plus the labor minutes the turn consumes, plus a share of rent and the card-system fee.

Keep the terms as named variables, so you can rerun them when a rate changes. Count the card-system per-transaction fee and the slice of the monthly platform charge that belongs to that turn along with everything else. Add every term and you have the cost of one turn.

Then set the vend price so the turn clears cost plus your target margin. Recheck the arithmetic when your water utility files a rate change, not once a year.

A card system changes the cash picture in two ways. It removes the coin count at the end of the day, and it adds a per-transaction fee plus a monthly platform charge. Both belong in the cost-per-turn formula, not in a separate line you forget.

If you are weighing new machines against repairs, run the numbers through a new vs used laundromat equipment cost guide before you commit capital.

The reserve that keeps you open

Machine replacement is the line owners defer, and it is the one that closes stores. A washer that fails on a Saturday with a full store and no spare is a lost weekend, not a repair bill.

Fund a replacement reserve monthly. The amount is your call, but the arithmetic is: reserve per month = (replacement cost of the fleet − salvage value) ÷ months of expected remaining life.

Track each machine's age and rebuild history. A top-load washer at year eight and a front-load at year twelve are different risks. When a machine's repair cost approaches a meaningful share of its replacement cost, the reserve should already be funded enough to act.

Closing the month in one sitting

Reconcile once a month, not daily. Pull the card-system report, the meter readings, and the bank deposit. They should agree.

No spreadsheet is required. Keep one page per month in a paper ledger: the deposit total, the meter count, and the card-system net go on three lines, and the five cost lines you paid that month go below them. The reserve lives in its own bank account with its own running balance, so funding it is one transfer and one line. Clip the receipts behind the page and you have a closing sheet you can hand to a CPA.

The IRS recordkeeping floor is the starting point: IRS Publication 583, Starting a Business and Keeping Records, says any system works as long as it clearly shows income and expenses and keeps the documents behind purchases, sales, payroll, and assets. A sole proprietor reports laundromat income and expenses on Schedule C filed with Form 1040 and depreciates equipment on Form 4562; with employees, Form 941 covers quarterly payroll taxes and Form 940 covers federal unemployment. The ordinary retention rule is three years after you file the return the records support, and at least four years after the due date of the tax or the date it was paid for employment tax records. See Internal Revenue Service: What kind of records should I keep? for the current wording.

If your card system, bank feed, and meter count do not agree, the gap is the finding. Chase it before you close the month.

Building the habit

A monthly count of reports that stay consistent tells you whether a change improved the operation or only moved work around. Pick three or four numbers, define each one, and keep the definitions stable.

One person needs authority to own the process and keep exceptions visible. That person should be able to explain the decision, find the evidence, and say when the next review is due.

For the software side, a laundromat bookkeeping system should export your data in a usable format before you need it. Test the export before you sign a renewal, not after you cancel.

Common questions

How often should I reconcile the books?

Monthly is enough for most laundromats, provided the card system and the bank feed are reconciled to the meter readings each time. Daily reconciliation is a habit that fits high-volume stores with multiple attendants. The test is whether you can explain any gap within a week.

What is the biggest cash flow mistake laundromat owners make?

Not funding the machine replacement reserve. Rent and utilities get paid because they are billed. The reserve is the line you have to pay yourself, and it is the first one skipped in a slow month. A store with a funded reserve survives a Saturday breakdown; one without it does not.

Do I need a CPA for a laundromat?

For routine bookkeeping, no. For depreciation schedules, entity structure, and how the IRS treats your equipment purchases, yes. Those are rulings that vary by your situation, and a CPA or the IRS itself is the right source. Do not take a forum answer on depreciation as settled.

How do I know if my vend prices are too low?

Compare cost per turn against vend price. If the turn does not clear cost plus your target margin, the price is low regardless of what nearby stores charge. Recheck after any utility rate change, and remember the card-system fee belongs in the cost, not outside it.
