Buying a Coin Laundromat vs. a Card Laundromat: The Diligence Difference

By Jason Taken, business broker · HedgeStone Business Advisors · Updated 2026-09-04 · 5 min read

What Each System Actually Proves

The essential distinction: a card system produces records the seller did not write. A processor settlement is generated by a third party and lands in a bank account, which makes it evidence in a way a handwritten count sheet is not.

That does not make coin stores untrustworthy. It means a buyer must assemble corroboration from other sources rather than relying on a single one.

Verifying a Coin Store Properly

Do all of these, not some of them.

1. Three years of tax returns, matched to the P&L line by line.
2. Bank statements for the same period. Deposits should show a consistent coin-deposit pattern with the frequency and rough amounts the seller describes.
3. Dated collection count sheets, ideally by machine or at least by bank of machines, for at least 12 months.
4. Attend a collection yourself. Ideally two, on different weeks, unannounced where the seller will permit it. This single step is worth more than any spreadsheet.
5. A theoretical revenue rebuild. Machine count times capacity times vend price times observed turns times 365 produces a ceiling. Claimed revenue above it is impossible; well below it may indicate an under-utilized store.
6. The water cross-check. Metered consumption compared against manufacturer per-cycle usage for the installed machines, yielding a range of implied cycles.
7. Observed traffic at several times of day and days of week, counted.

When those seven agree, a coin store's revenue is well-established. When two or more disagree, you have found something important.

The CLA's diligence framework is a useful structured companion to this work (Source: Coin Laundry Association, Best Practices for Due Diligence in Laundromat Acquisitions).

Verifying a Card Store

Faster, and not automatic.

1. System exports by machine and by day, pulled from the system in your presence rather than emailed as a summary. Ask for the raw export.
2. Processor settlement reports for the same period.
3. Bank deposits matched to settlements.
4. Tax returns matched to the total.
5. Any remaining coin or cash component, verified the coin way.
6. The water cross-check, same as always.

Then the items specific to card systems:

• Processing fees. What rate, what monthly minimums, what equipment lease or software subscription. These sit in the P&L and are frequently understated in a seller's summary.
• Hardware age and vendor. Readers and kiosks have a service life, and replacement is a per-machine cost.
• The vendor agreement. Term, assignability to you, and what happens if you switch platforms.
• Stored-value balances. Money customers have loaded onto cards but not spent is a liability that transfers with the store. Quantify it and address it in the purchase agreement.

Does One Sell for More?

Not because of the payment system as such. Value comes from normalized earnings times a multiple — median 3.50x, middle half 2.72x to 4.50x across 855 reported sales (Source: BizBuySell, 2021-2025) — and where a store sits in that spread is driven by evidence quality, lease term, equipment condition, and utility position.

A card system helps on exactly one of those: evidence quality. That is a real effect, because a buyer facing a well-documented revenue history has less to discount for. But a coin store with three consistent years of returns, matching deposits, clean count sheets, and a water cross-check that reconciles has good evidence too — just assembled differently.

Where the systems genuinely diverge on economics:

The pricing flexibility line is worth attention. Being able to price in increments other than quarters, or to price by cycle type, gives an operator tools a coin store does not have — and for a buyer intending to reprice, that flexibility can be worth more than the diligence advantage.

The Trade-Area Question

Whether a store's customers will use cards is a local fact, not a general one. The FDIC's household survey documents that a share of U.S. households remain unbanked, with the rate varying considerably by income, region, and demographic group (Source: Federal Deposit Insurance Corporation, 2023 National Survey of Unbanked and Underbanked Households).

Practically, before assuming a conversion will work:

• Watch what competing stores in the same trade area use, and whether they are busy
• Watch how customers at the target store pay if it already offers both
• Consider a hybrid — coin plus card — which preserves accessibility while adding data and flexibility
• Talk to the attendant if there is one; they know what customers complain about

A conversion that loses a meaningful share of customers costs far more than it saves in coin handling.

Underwriting a Conversion

If you intend to convert after purchase, treat it as a capital project with an honest return calculation.

Costs: hardware per machine, kiosk or reader infrastructure, installation, network setup, and any software subscription or processing minimums. Because hardware scales per machine, the CLA-surveyed median machine count gives a sense of scale — a full conversion is a five-figure project at most stores rather than an incidental expense.

Benefits, each of which is a separate assumption: reduced coin handling time, better data, pricing flexibility, potentially higher average tickets, and easier remote oversight if you intend semi-absentee ownership.

Risks: customer loss in a cash-preferring trade area, processing fees permanently in the expense line, and vendor dependence.

Do not underwrite the purchase price on post-conversion economics. Buy the store on what it earns now; treat the conversion as your project and your upside.

Summary

Coin versus card changes the diligence method, not the valuation method. Card and mobile systems produce third-party records that make verification faster and more conclusive; coin stores require corroboration assembled from returns, deposits, count sheets, personal observation, and a theoretical rebuild. Run the water cross-check on both. And if you plan to convert, price the store on what it earns today and keep the conversion as your upside rather than the seller's.
