- The costliest ATM business mistakes are buying the machine before signing a location, placing it where customers rarely use cash, and running out of cash at peak times.
- Put every placement in writing: term, venue split, power, access hours, and what happens if the business is sold.
- Never buy a used ATM until your processor confirms in writing that its EMV reader and PIN pad meet current requirements, including TR-31 key blocks.
- Keep ATM funds in a dedicated account and vary your cash-loading schedule.
- Fix or relocate weak machines before buying more.
The most expensive ATM business mistakes are rarely dramatic. They are quiet: buying the machine before the location, running out of cash on a Saturday night, signing a placement deal on a handshake, and buying a used unit your processor will not certify. Each one costs a few hundred dollars a month or a few thousand at once, and nearly all of them are avoidable before the machine is bolted down.
Part of our complete guide: best cash flow businesses.
We wrote this for someone who has run the numbers, likes the idea of a cash route, and wants to skip the tuition that earlier operators paid. It is organized in the order the mistakes tend to happen: before you buy, when you place, while you operate, and when you grow. For the income side, see how much ATM machines make; for the startup budget, see our ATM startup cost breakdown.
The mistakes at a glance

Mistakes before you buy anything
1. Buying the machine before you have a location
It feels productive to order the ATM first. Then it sits in a garage while you learn that the bar owner who said "sure, bring one by" meant "maybe, talk to my partner." Every week the machine is not placed is a week of depreciation and zero surcharges. Get a signed placement agreement, measure the spot, confirm there is an outlet, and only then order a machine sized to that venue. Our ATM buyer’s guide shows how to match the model to the site.
2. Mistaking foot traffic for cash traffic
A busy coffee shop where everyone taps a phone can do worse than a quiet dive bar that only takes cash for pool tables and tips. The question is not "how many people walk in," it is "how often does someone ask where the nearest ATM is?" Ask the owner directly. Also walk the block: if there is a bank branch next door with a free ATM, most of your would-be customers will use that one. Cash was only about 13% of US consumer payments by count in 2025, according to the Federal Reserve’s payment diary, so pick venues where that share is clearly higher. We cover this in the best locations for ATM machines.
3. Buying a used machine without checking compliance
A $900 used ATM is a bargain only if your processor will run it. EMV readers became expected after the card networks shifted fraud liability for ATMs in 2016 and 2017, and PCI moved ATM key exchange to TR-31 key blocks starting in 2025. Older PIN pads and software that cannot support that can be refused. Get the model, PIN pad version, and firmware from the seller, and get a written yes from the processor before paying.

4. Handshake deals
The owner likes you, so you skip the paperwork. Six months later the bar sells, the new owner wants the space for a jukebox, and your machine is sitting on the curb. A simple written agreement should cover the term, renewal, the venue’s share of surcharge (if any) and how it is paid, who provides power, your access hours for servicing, and what happens if the business is sold or closes. See our guide to ATM placement agreements and revenue share for the clauses.
5. Giving away the margin to win the spot
New operators offer big venue splits to close the deal, then discover that after the split, wireless, and processing there is little left. Run the math at a conservative volume before you offer anything. If the only way to win a location is to give away most of the surcharge, the location is telling you something.
6. Signing processing without reading it
The dealer bundles processing, the form looks routine, and you sign. Then you learn the term is five years with auto-renewal. Compare at least two written quotes and read the termination clause. Our walkthrough on how to choose an ATM processor has a comparison grid.
Mistakes while operating
7. Running out of cash
An empty vault earns nothing, and a customer who sees "out of service" twice stops trying your machine. Size the load to the busiest week, not the average one, and track dispense rates per machine in your processor’s portal. Whether to self-fund the cash or use a vault-cash provider is a real tradeoff; see self-load vs third-party vault cash.
8. Not watching for downtime
Cassette jams, a dead modem, or a receipt printer out of paper can stop the machine quietly. Turn on every status alert your processor offers, and give the venue manager your cell number with a simple ask: text me if it says out of service.
9. Sloppy cash handling
Loading at the same time every Friday is a pattern anyone can learn. Vary your schedule, keep the machine bolted to the floor, never count cash in front of customers, and move it in a locking bag. A locking deposit bag is cheap. A bill counter with counterfeit detection saves time at home once you are loading several machines; we compare models in the best bill counters for vending and ATM operators. Check with your insurer about coverage for cash inside the machine versus cash in transit; they are often treated differently. Our vending machine insurance guide covers the general shape of route coverage.
10. Mixing business and personal money
Federal examiner guidance notes that a separate account used only for ATM replenishment and settlement gives a bank clearer visibility into the flow of funds. That same separation makes your bookkeeping and taxes far easier. Many operators also form an entity before placing the first machine; see ATM business taxes and LLC setup and talk to a tax professional about your situation.
Mistakes when growing
11. Buying a "turnkey" placed-ATM package blind
Some companies sell ATMs already placed at a location, sometimes with a management fee attached. A few are fine. Others sell a weak location at a strong price. Ask for the terminal’s actual monthly transaction reports, the placement agreement, and the processing contract. If the seller cannot or will not share real history, pass. The same due diligence applies to buying an existing ATM route.
12. Scaling a weak machine instead of fixing it
Here is an illustrative example, not a real operator. Jordan places three machines in six months. Two do well; one in a laundromat averages barely a withdrawal a day. Instead of buying a fourth machine, Jordan asks the owner to move the ATM from the back wall to the front counter, adds window signage the venue approves, and gives it 60 days. When volume barely moves, Jordan relocates the machine to a bar that had asked about one. The fourth purchase waits until the three existing machines all clear his minimum. That discipline, not the machine count, is what keeps the route profitable.
How to avoid most of these at once
Almost every mistake above starts with a weak location list. When you only know three possible venues, you say yes to the wrong one and give away too much to keep it. VendBuddy finds bars, laundromats, convenience stores, and other businesses in any ZIP with the owner or manager’s contact, so you can pitch twenty places and choose the best three. Credits come in one-time packs if you would rather not subscribe. Build the list, sign in writing, verify the hardware, read the processing contract, and then buy the machine.
The fastest way to test this in your own ZIP is the . Search once, see which businesses sit within a few miles, and reveal five contacts for nothing. It will not tell you who says yes, but it saves the afternoon you would spend building the list by hand.
Frequently Asked Questions
Why do most ATM businesses fail or make little money?
Most weak ATM results trace back to location: a machine where customers rarely need cash, or where a free bank ATM sits nearby, may do only a handful of withdrawals a week. Other common causes are running out of cash, frequent downtime, and giving away too much of the surcharge to the venue. The model can work, but only at venues with real cash demand.
Should I buy an ATM before I find a location?
No. Get a signed placement agreement first, confirm the spot and power, and then order a machine sized to that venue's volume. Buying first leaves thousands of dollars of hardware idle while you search, and pushes you to accept a weaker location just to get it placed.
What should an ATM placement agreement include?
At minimum it should cover the term and renewal, the venue's share of the surcharge if any and how it is paid, who supplies power, when you can access the machine for servicing, and what happens if the business is sold, closes, or wants the machine removed. Keep it short and clear. Have a local attorney review your template if you plan to use it for many locations.
Is it a mistake to buy a used ATM machine?
Not automatically, but it is where many new operators lose money. The used unit must have an EMV card reader and a PIN pad and software that support the TR-31 key block format PCI required from January 1, 2025. Upgrade kits can cost $500 or more, which erases the discount. Get your processor's written approval of the exact model before paying.
How do I keep my ATM from running out of cash?
Track each machine's dispense rate in your processor's portal and size the cash load to your busiest week, not your average. Consider a larger cassette at high-volume venues, and set up low-cash alerts if your processor offers them. Some operators use a vault-cash provider so the cash itself is not their capital.
