Payment Terminals for Small Businesses: How to Choose and Set Up
What a payment terminal does and why you need one
A payment terminal is the machine that reads a customer's card, phone, or other payment method and sends that information to your bank so the money lands in your account. It sits on your counter, in your hand, or on your phone. Without one, you can only take cash—and you lose sales from customers who don't carry it.
The terminal itself is just hardware. It connects to a payment processor (the company that actually moves the money) and a merchant account (the bank account where deposits land). You rent or buy the terminal, pay a monthly fee to the processor, and pay a small percentage of each sale as a processing fee. That percentage varies by card type and by processor, usually between 1.5% and 3.5% per transaction.
The terminal you choose depends on your business type: a coffee shop needs something different than a plumber who visits job sites, which is different from an online store. The wrong choice costs you in monthly fees, slow deposits, or lost sales when the system fails.
Key Takeaways
- Payment terminals come in three main types—countertop, mobile, and virtual—and each charges different monthly fees and processing rates depending on your business model.
- You will pay a monthly terminal rental fee (usually $10 to $50), a processing fee per transaction (typically 1.5% to 3.5%), and sometimes a PCI compliance fee or batch fee, so compare the full cost, not just one line item.
- Countertop terminals work best for retail and restaurants; mobile terminals work for delivery, events, or field service; virtual terminals work for phone and mail orders.
- Your processor and your bank are often different companies, so you need both a merchant account and a payment processor, and switching between them can take two to four weeks.
- Deposits usually arrive one to three business days after a sale, but some processors hold funds longer or charge extra for next-day deposits.
Countertop terminals for retail and restaurants
A countertop terminal (also called a point-of-sale terminal or POS terminal) sits on your counter and connects to your internet. The customer inserts, taps, or swipes their card. The terminal reads it, asks for a signature or PIN, and sends the data to your processor. You see the sale in your system right away, and the money deposits into your bank account within one to three business days.
Countertop terminals work well if customers come to you—a retail store, restaurant, salon, or coffee shop. They are reliable, fast, and most customers expect them. The downside is that they need a stable internet connection and a fixed location. If your internet goes down, you cannot process cards until it comes back up (though some newer terminals can cache a few transactions and retry them later).
Monthly costs run $15 to $50 for the terminal rental, plus 1.5% to 2.9% per transaction for card-present sales (when the customer is standing in front of you). Some processors charge an extra $5 to $15 per month for PCI compliance (a security standard that protects card data). If you process a high volume, the percentage fee matters more than the monthly rental; if you process a low volume, the monthly fee matters more.
Mobile terminals for field service and events
A mobile terminal is a small device that connects to your phone via Bluetooth or cellular data. You can hold it in your hand, tap a card against it, or insert one. It works anywhere you have a phone signal—at a customer's home, a farmers market, a pop-up event, or a delivery route. The sale appears in your system immediately, and deposits arrive the same way as with a countertop terminal.
Mobile terminals are essential if you visit customers instead of waiting for them to come to you—plumbers, electricians, contractors, delivery drivers, and event vendors all use them. They are also cheaper to rent than countertop terminals, usually $10 to $30 per month, because the hardware is simpler. Processing fees are similar: 1.5% to 2.9% for card-present sales.
The trade-off is reliability. A mobile terminal depends on your phone's signal. If you lose connection, the transaction may fail or delay. Some devices can store a transaction temporarily and retry it when the signal returns, but not all. Test the signal strength in the areas where you work before you commit to a mobile-only setup.
Virtual terminals for phone and mail orders
A virtual terminal is software you access through a web browser or app. You type in the customer's card number, expiration date, and CVV (the three-digit code on the back). You hit submit, and the payment processes. This works for phone orders, mail orders, or any sale where the customer is not physically present and you cannot swipe or tap their card.
Virtual terminals are cheaper to set up—often no hardware rental at all, just a monthly software fee of $5 to $20. But the processing fee is higher: 2.5% to 3.5% per transaction, because the risk is greater when you cannot see the card or the customer. You also cannot use a virtual terminal if the customer is standing in front of you; that is considered card-not-present and triggers the higher fee even if you could swipe.
Virtual terminals are common for small businesses that take orders by phone, mail, or email—tutors, consultants, repair shops that quote over the phone, or online retailers who also take phone orders. If you mix in-person and remote sales, you will need both a countertop or mobile terminal and a virtual terminal.
Understanding the full cost: fees that add up
The price of a payment terminal is not just the monthly rental. You also pay per-transaction fees, and sometimes hidden fees that surprise you. Here is what to look for:
Monthly terminal rental: $10 to $50, depending on the device and processor. Some processors waive this if you process a minimum volume each month (often $1,000 or more).
Processing fee per transaction: Usually a percentage of the sale (1.5% to 3.5%), sometimes plus a flat fee of $0.10 to $0.30 per transaction. Card-present sales (in-person) are cheaper than card-not-present (phone or mail). Debit cards are usually cheaper than credit cards.
PCI compliance fee: $5 to $15 per month. This is a security fee that protects card data. Some processors include it; others charge it separately.
Batch fee: $0.50 to $1.50 per day, charged when you close out your sales at the end of the day. Not all processors charge this, so ask.
Early termination fee: $100 to $500 if you cancel before your contract ends (usually 12 to 36 months). Some processors have no contract; others lock you in.
Next-day deposit fee: $5 to $15 per deposit if you want money faster than the standard one to three business days. Standard deposits are usually free.
Before you sign up, ask the processor for a written breakdown of all fees. Calculate what you will pay in a typical month based on your expected sales volume. A processor with a low percentage fee but a high monthly rental might cost more than one with a higher percentage and no rental, depending on your volume.
How to choose between processors
Your payment processor is the company that actually moves the money from the customer's card to your bank account. Common processors include Square, Toast, Stripe, PayPal, Clover, and traditional merchant services companies. Each one has different hardware, fees, and features.
Start by deciding what type of terminal you need (countertop, mobile, or virtual). Then compare processors that offer that type. Look at the full monthly cost for your expected sales volume, not just the percentage fee. Ask about contract length—some processors lock you in for 12 to 36 months, while others let you cancel anytime. Ask about deposit timing: most deposit within one to three business days, but some hold funds longer or charge extra for faster deposits.
Also ask about customer support. If your terminal breaks or your internet goes down, how fast can they help? Some processors offer phone support 24/7; others only email or chat during business hours. For a retail store or restaurant, downtime costs money, so fast support matters.
Finally, check whether the processor integrates with your accounting software or point-of-sale system. If you use QuickBooks, Square Online, or a specific restaurant POS, make sure the processor you choose can send sales data directly to it. Manual entry wastes time and creates errors.
Setting up your merchant account and getting started
Before you can process payments, you need two things: a merchant account (a bank account where deposits land) and a payment processor (the company that moves the money). Sometimes the same company provides both; sometimes they are separate.
To open a merchant account, you will need your business license, tax ID, a recent bank statement, and sometimes a personal credit check. The processor will ask about your average transaction size, your monthly sales volume, and your industry. Some industries (like cannabis, adult services, or high-risk goods) are harder to approve because processors see them as higher risk.
The approval process usually takes three to seven business days. Once approved, the processor sends you the terminal (if you are renting hardware) and login credentials for your account. You set up the terminal, connect it to your internet or phone, and start processing. Your first deposit usually arrives five to ten business days after your first sale.
If you already have a merchant account with your bank, you may be able to use a different processor with it—but not always. Ask your bank whether your account is locked to a specific processor or whether you can switch. Switching processors while keeping the same merchant account can save you time, but it is not always possible.
What happens when things go wrong
Payment terminals fail. Internet goes down, cards get declined, customers dispute charges. Here is what to expect:
Internet outage: If your internet goes down, most modern terminals can store a few transactions and retry them when the connection comes back. Older terminals cannot, and you will have to ask customers to pay cash or come back later. This is why internet reliability matters for retail and restaurants.
Declined card: The terminal will tell you the card was declined and usually why (insufficient funds, expired card, fraud block). Ask the customer for a different card or payment method. The declined transaction does not charge the customer or you.
Chargebacks: A customer disputes a charge with their bank, claiming they did not authorize it or did not receive what they paid for. The bank pulls the money back from your account and charges you a $15 to $100 chargeback fee. You can dispute the chargeback by providing proof (a receipt, email confirmation, tracking number), but it takes time and you might lose. Keep records of every transaction.
Terminal malfunction: If the terminal breaks, contact your processor's support line. They can send a replacement, usually within one to three business days. In the meantime, ask whether they can provide a loaner or whether you can process payments through a virtual terminal or your phone.
Frequently Asked Questions
Can I use the same terminal with different processors?
Usually no. Most terminals are locked to a specific processor and will not work with another one. If you switch processors, you will need a new terminal. This is why contract length and early termination fees matter—switching is expensive and time-consuming.
How long does it take to get paid after a sale?
Most processors deposit within one to three business days. Some hold funds longer (up to five to seven days) if you are new or if you process a high volume. A few processors offer next-day deposits for an extra fee. Ask the processor for their standard deposit timeline before you sign up.
What if a customer's card is declined?
The terminal will display a decline message and usually tell you why (insufficient funds, expired card, fraud block, or the bank is not responding). Ask the customer for a different card or payment method. A declined transaction does not charge anyone and does not cost you a fee.
Do I need a separate terminal for online sales?
If you sell online through a website, you do not need a physical terminal. You use a virtual terminal or a payment gateway (software that processes cards without hardware). If you also take in-person sales, you will need both a physical terminal for the store and a virtual terminal or gateway for online orders.
What happens if I cancel my processor before my contract ends?
You will usually owe an early termination fee, typically $100 to $500. Some processors have no contract and let you cancel anytime with no penalty. Before you sign up, ask about the contract length and what it costs to leave early.
