A POS fees comparison is three bills, processing, software, and hardware. Line up only the advertised card rate and you hide the monthly software line and the terminal you rent or own. We set up merchant accounts and registers for liquor, convenience, grocery, gas, and bodega counters, and we read statements for a living. The brochure rate is one line. The rest of the month still has to clear.
What a POS fees comparison has to include
A real comparison lines up every line that hits the bank account, not the one percentage on the homepage. Processing is the variable bill. Software is the access bill. Hardware is the equipment bill. Miss one of those and the cheaper-looking offer is just a shorter quote.
Processing is a percentage plus a fixed per-transaction fee. On a two-dollar energy drink, the fixed fee decides the cost, not the percentage. On a high-ticket bottle, the percentage does more of the work. Same schedule. Different tickets. That mix is why a flat advertised rate can look kind on a liquor-store Saturday and harsh on a convenience-store night of singles.
Software is the monthly line, or the claim that there isn’t one. Some platforms fold the register into processing. Others bill a subscription, then bill again for inventory, extra lanes, or a back-office login. PCI often sits here. Complete the processor’s checklist and some programs waive the non-compliance fee. Leave it undone and the fee prints. Card data is handled under the processor PCI program.
Hardware is buy or rent. A handheld you own is a one-time outlay. A handheld you rent is a monthly line that never stops. If rented equipment is not returned, that is a separate fee on the way out. The register, the scanner, and the cash drawer belong on this bill even when the processing quote never mentions them.
Match how the card is taken. A tap, dip, or swipe at the counter is not a keyed number, a phone order, or an online cart. American Express may carry additional terms. Disputes are their own line. Funding is not a fee, but batching at the end of the day starts the deposit clock. A late batch pushes the money, not the sale.
The counter work belongs in the same conversation. EBT and SNAP need item eligibility and split tender in the register. A lottery terminal will never integrate, so the work is reconciliation. Tobacco scan data needs a file the register can actually produce. Those are not processing percentages. They still decide whether the setup is usable.
Processing, software, and hardware as three bills
These three bills move independently. A lower card rate with a rented terminal and a software subscription can cost more than a higher-looking rate with included software and a terminal you own. You cannot see that on a homepage.
| Bill | What it is | What to line up |
|---|---|---|
| Processing | The cost of taking cards | Percentage, per-transaction fee, in-person versus keyed, disputes |
| Software | Access to the register and reporting | Monthly line or none, PCI, statements, extra lanes |
| Hardware | The terminal, scanner, and drawer | Buy versus rent, how many units, what happens if you leave |
We publish sample processing for new accounts applying directly through the site. In person, cards swiped, dipped, or tapped, the sample is 2.50% plus $0.10. Keyed and online, the sample is 2.90% plus $0.25. Pricing is subject to underwriting, the merchant category code, and the merchant agreement. Rates can differ from the samples and are subject to change. Nothing published is an approval, a quote, or a guarantee.
On the software bill, monthly, annual, setup, statement, PCI, customer service, and batch fees are published as $0.00. The account is month to month. There is no long-term contract and no early termination fee. A monthly minimum of up to $25.00 applies only to idle or barely used accounts. Once processing charges pass $25 in a month, it is waived. A PCI non-compliance fee of up to $79.00 applies only if the checklist is not completed.
On the hardware bill, Tap to Pay is included with every merchant account. A handheld smart terminal is $199.00 to buy, or $24.95 a month to rent, with one free per location. An all-in-one terminal is $399.00 to buy, or $49.95 a month to rent. If rented equipment is not returned, that carries a $395 fee.
That is three columns, not one rate. Our POS system cost page walks the same split for a full setup. If you are staring at a $0 software claim, read do POS systems have a monthly fee before you treat software as free.
Flat rate versus interchange plus, in plain words
A flat rate is one percentage plus one fixed fee for a whole class of cards. You can multiply it. You don’t need a card-brand decoder to read the statement. It is simple on purpose. It also averages. Rewards cards, debit, and a basic credit card sit under the same sticker, so some tickets subsidize others.
Interchange plus pricing passes through the applicable network and issuer costs and adds the processor’s markup. You see more lines. Whether it costs less than a flat rate depends on card mix, volume, and the full fee schedule. High volume stores may qualify for different pricing. A liquor store and a gas station carry different merchant category codes. That code affects interchange cost and underwriting.
Neither model wins on a brochure. The fixed per-transaction fee decides a two-dollar sale. The percentage decides a high-ticket bottle. A store that rings a lot of small baskets feels the dime. A store that rings fewer, larger tickets feels the percent. Mix in keyed sales and a weekend of tap-to-pay, and the same schedule produces two different months.
Zero cost processing is a third shape. The merchant pays 0% and the cardholder covers 3.95% at checkout instead. State law and card network and acquirer rules vary. Cash discount, surcharging, and dual pricing are three different programs, with different legal treatment by state and different card brand requirements for how prices are posted. Check the current rule for your own state. Read the network’s own current merchant rules. We confirm the written program terms with the merchant before setup.
If you want to run the arithmetic on a stack of tickets, use the credit card processing fee calculator with the same volume, ticket mix, and in-person versus keyed split on every offer. That is how you compare POS processing fees without letting one homepage percentage stand in for a month.
What a statement comparison actually lines up
A statement comparison lines up the same month, the same card mix, and the same number of tickets. It does not line up last October’s effective rate against this week’s advertised rate. Those are different objects.
Start with in-person volume and keyed volume as two piles. Then count tickets, not just dollars. Two stores can both run the same dollars through the terminal. One of them did it in a few hundred sales. The other did it in a few thousand. The fixed fee hits the second store much harder. That is the small-basket mechanism.
Then pull the non-processing lines that still left the account. Monthly software. PCI. Statement fees. Batch fees. A monthly minimum on a slow month. Dispute fees, $25.00 each on our published schedule, and $25.00 per representment if you contest one. Hardware rent if the terminal is not owned. Those lines do not care what the swipe percentage was.
Deposits belong in the comparison even when they are not a fee. On our published funding, deposits land in the merchant’s bank the next business day. Batching at the end of the day starts that clock. A late batch pushes the deposit. A processor that looks cheaper on the rate and slower on the deposit is a cash-flow problem.
Read the merchant category code on both offers. Underwriting reviews business type, expected volume, and average ticket. That review sets final pricing. A sample rate on a website is not the rate on the merchant agreement. Every merchant account goes through underwriting. No guaranteed approval. That phrase is a warning sign, not a selling point.
Sales history does not migrate when you leave. Download statements before you close the old account. The item library and pricing can move. Historical transactions stay with the old processor. You need those PDFs if you want to reconstruct what you actually paid.
How we run two statements side by side
We run both against your statement. You send the current processor’s statement and the other quote, and we put the same month of sales through both fee schedules. We don’t invent a savings percentage before anyone has read the paper. We don’t pick a winner from the advertised rate.
The work is mechanical. We split tap, dip, and swipe from keyed and online. We apply each schedule’s percentage and per-transaction fee to those piles. We add the software line, the hardware rent or the purchase, and the account fees that are not always zero. We flag a monthly minimum, a PCI non-compliance line, and dispute costs so they are visible. Then we hand you the three bills, side by side.
What we can’t do is promise the number that prints on your merchant agreement. Underwriting, the merchant category code, and the merchant agreement decide pricing and approval. Rates can differ from the samples and are subject to change. Setup and support happen by phone, video, and shipped, pre-configured hardware. There is no local rate and no city exception.
We also scope the counter, not just the fees. Case breaks in the item file. Split tender on EBT. Age checks at liquor and convenience. A lottery terminal that stays on its own island. Tobacco scan data in the format the program asks for. If the register cannot produce the file, the processing rate does not matter.
The published rates are the sample column for a new account applying directly. Use them as the starting grid, then read your statement through them. If you came here looking for a single cheapest sticker, that search lives on what POS system has the lowest fees. This page is the method. Three bills. Same month. No teaser rate that resets in month thirteen.
Frequently asked questions
Does a POS charge a fee on every sale?
Cash does not carry a card processing fee. Cards do, as a percentage plus a fixed per-transaction fee, and some setups add a software or hardware line on top of that. A POS fees comparison has to show all three bills, because a $0 software claim can still sit next to processing and a rented terminal.
How much does Square charge for POS transactions?
Square’s US fees page, retrieved 2026-09-11, listed tap, dip, or swipe at 2.6% + 15¢, 2.5% + 15¢, or 2.4% + 15¢ by plan, online at 3.3% + 30¢ or 2.9% + 30¢, and keyed at 3.5% + 15¢. Square can change that page. Read the current figures on Square’s own fees page and still add software and hardware before you call it a comparison.
How much does a POS system cost once you add the other two bills?
There is no single sticker, because processing moves with volume and ticket mix, software may or may not bill monthly, and hardware is a purchase or a rent line. Our published hardware starts at one free handheld per location, then $199.00 to buy or $24.95 a month to rent, with an all-in-one at $399.00 or $49.95 a month. Put those next to processing using your own statement as the volume.
