Converting a Laundromat From Coin to Card: Cost and Payback

By Jason Taken, business broker · HedgeStone Business Advisors · Updated 2026-09-05 · 9 min read

What Actually Drives the Cost?

Three layers, and only one of them scales with store size:

Per machine. Readers or retrofit kits, one per machine, plus any adapter hardware an older control board needs. This is usually the largest line and it is driven by your specific models.

Per store. A kiosk or value-transfer machine, network hardware, and installation. Largely fixed regardless of machine count.

Ongoing. Platform or software fees, processing fees, and support. This is not a conversion cost but it belongs in the decision — see card processing fees.

The published ranges you will find vary enormously, and the reason is that they are averaging across very different products. A basic tap-to-pay retrofit and a full system with screens, tiered pricing, remote management and loyalty are not the same purchase. Quotes on your actual machine list are the only figures worth planning against.

Why Compatibility Decides Everything

Ask the vendor to price against your equipment schedule — make, model, serial and control generation for every machine — before any other conversation.

The answers fall into three groups:

That third row is where a payment decision becomes an equipment decision. If a meaningful share of your fleet cannot be converted, you are choosing between a partial conversion — which means running two payment systems and confusing customers — and bringing forward a retool you had not budgeted.

Which is exactly why the timing advice below matters more than any cost estimate.

When Is the Right Time?

During a retool. New machines arrive card-ready or card-compatible, installation labor is already being spent, and the store is already disrupted. The incremental cost of adding the payment system at that point is far lower than doing it as a standalone project, and there is no compatibility constraint to work around. See laundromat retool cost.

When the coin infrastructure needs investment anyway. If the changer is failing or the coin handling is at end of life, the comparison is not conversion versus nothing — it is conversion versus replacing coin equipment you may not want long term.

When collection or theft is a live problem. If you are absorbing repeated coin-box losses, the security case can carry the decision on its own. See theft and security.

Not when the fleet has a few years left and everything works. Converting mid-life on machines you will replace in three years means buying the same capability twice.

What Changes Operationally?

Pricing becomes editable. This is the change owners underrate. Coin pricing is constrained to quarter increments and requires physical adjustment; card pricing can be set precisely, varied by machine size, and changed centrally. It makes the pricing discipline described in raising vend prices practical rather than theoretical.

Collection changes shape. Less cash on site, fewer trips, less counting — but not zero if you keep coin as an option.

You gain data. Machine-level starts, cycle revenue, price history, refunds, promotions and management functions, all exportable. This is the operational benefit that keeps paying.

You gain a dependency. When the payment system is down, the store is down. Ask about uptime, support response and what the failure mode is — whether machines fall back to any usable state or simply stop.

Refunds become a process. A customer who loses money to a failed cycle cannot be handed a quarter. Whatever the system's refund mechanism is, someone has to operate it, and management functions need controls.

What Does Not Change?

Vandalism. Damage for its own sake is unaffected by whether there is cash in the building.

Machine condition. A card reader on a failing washer is a failing washer that accepts cards.

Trade-area economics. Competitive density, renter demand and traffic patterns are unmoved by a payment technology.

The cash-preferring customer. Some of your base pays in cash by preference or necessity. Removing that option removes them, and the size of that group is a local fact, and not a national one. Dual acceptance is the usual answer, at the cost of keeping the coin infrastructure.

How Does It Look at Sale?

The middle half of reported laundromat sales closed at 2.72x to 4.50x owner earnings (Source: BizBuySell, 2021-2025), and where a store lands in that range depends heavily on how well its revenue can be verified.

That is the strongest sale-side argument for a card system, and it is not about the technology. Verifying revenue in a coin store is the hardest part of laundromat diligence — the process runs on bank deposits, collection logs, and a physical rebuild from machine counts and observed turns. A store that can export machine-level cycle data hands the buyer a third-party record instead, and the argument moves on quickly. See buying a coin laundromat vs a card laundromat for the same question from the buyer's side.

The corollary is that the data only helps if it exists over time. A system installed two months before listing produces two months of history, which is not what a lender's valuation is built from.

What Should You Establish Before Committing?

Compatibility, and it should be the first conversation, not a detail confirmed later — because the answer decides both the cost and whether the project is possible at all.

Ask the vendor to price against your actual equipment schedule: make, model, serial and control generation for every machine. The answers fall into three groups, and the third is where budgets break.

Fully supported. A straightforward retrofit at the lowest per-machine cost, with the full feature set.

Supported with adapters. Higher cost per machine, and sometimes reduced functionality.

Not supported. The machine has to be replaced to be converted.

If a meaningful share of your fleet falls into the third group, you are no longer making a payment decision. You are choosing between a partial conversion — two payment systems in one store, which confuses customers and complicates reporting — and bringing forward a retool nobody had budgeted.

Three other things to establish at the same time. What the recurring costs are, since platform and processing fees continue where the hardware does not. What happens to the coin infrastructure, because a store keeping both is maintaining two systems. And whether your trade area has a meaningful share of customers without cards, which is a fact about the neighbourhood rather than about the technology — and the one factor that can make a well-executed conversion reduce revenue.

What Actually Changes Day to Day?

More than the payment method, and the operational changes are usually the ones owners appreciate most afterwards.

Pricing becomes practical rather than theoretical. Coin pricing is constrained to quarter increments and requires physically adjusting machines. Card pricing can be set precisely, varied by machine size, and changed centrally. Owners who found price changes painful enough to defer for years find them straightforward afterwards, which tends to be worth more than the conversion cost.

You get machine-level data. Starts, cycle revenue, price history, refunds, and management functions — all exportable. That is an operating tool now and a diligence document later, because verifying revenue is the hardest part of selling a coin store.

Collection changes character. Less coin to handle, count and bank, and less exposure to coin-box loss. It does not disappear entirely on most stores, since changers and vending usually remain.

New failure modes appear. Readers fail, connectivity drops, and customers occasionally need a refund for a transaction that did not complete. These need a process and someone able to execute it, and an unattended store needs to think about how a refund is handled when nobody is present.

Some customers need help at first. A transition period where an attendant or clear signage matters more than usual, particularly with older regulars.

What does not change: the store still has to be clean, the machines still have to work, and the trade area is still the trade area. A payment system is an improvement to a good store and does not rescue a poor one.

When Is the Cheapest Time to Do It?

During a retool, by a wide margin.

New machines arrive card-ready or card-compatible, the installation labour is already being spent, the store is already disrupted, and the compatibility constraint disappears entirely. The incremental cost of adding the payment system at that point sits well below the cost of doing it as a standalone project.

The second-best moment is when the coin infrastructure needs investment anyway. If the changer is failing, the comparison is not conversion against doing nothing — it is conversion against replacing coin equipment you may not want in five years.

The worst moment is mid-life on a fleet you intend to replace soon. Converting machines with three years left means buying the same capability twice, and the second purchase arrives with the new machines whether you want it or not.

A fourth consideration applies if a sale is anywhere in view. The verification benefit accrues over time, not on installation — a system fitted two months before listing produces two months of history, which is not what a valuation is built from. If you expect to sell in a few years, that argues for doing it sooner rather than later, or not at all.

Summary

Price the conversion against your actual machine list, because compatibility drives both cost and capability. The strongest timing is during a retool, when the constraint disappears and the labor is already committed. Expect the risk profile to shift rather than shrink, expect pricing flexibility and data to be the durable operating gains, and understand that the data's value at sale comes from having collected it for years rather than months.
