What a payment processing company does
A payment processor is the company that moves money from your customer's bank account or card to yours. When someone buys something from you — whether you're a contractor, real estate agent, property manager, or home-based service provider — the processor handles the transaction behind the scenes. They collect the payment, verify the funds are real, take a fee, and deposit what's left into your account.
The processor is not your bank. Your bank holds your money once it arrives. The processor is the middleman that makes the handoff happen. They connect to the customer's card network (Visa, Mastercard, American Express), check that the card is valid and has funds, and then tell your bank to expect a deposit. If something goes wrong — the card is declined, the customer disputes the charge, or fraud is detected — the processor is the one investigating and deciding what happens next.
Most homeowners who take payments online or by card will work with a processor at some point, even if they don't think of it that way. If you use PayPal, Square, Stripe, or your bank's merchant account, you're using a processor. Each one charges differently and offers different tools.
Key Takeaways
- Payment processors move money from customer cards or bank accounts to yours, taking a fee in the process — typically 2 to 3 percent plus a per-transaction charge.
- Different processors suit different situations: online stores, in-person sales, invoicing, or recurring payments like rent collection.
- Your processor is responsible for fraud detection, chargebacks, and security, but you remain liable if you don't follow their rules.
- Processors require you to follow Payment Card Industry (PCI) standards, which means storing customer data securely or not storing it at all.
- Monthly fees, transaction fees, and chargeback fees vary widely — comparing three processors before choosing can save hundreds of dollars a year.
How processors charge and what fees to expect
Payment processors make money by taking a cut of every transaction. The fee structure usually has three parts: a percentage of the sale, a flat per-transaction fee, and sometimes a monthly account fee.
A typical breakdown might look like 2.9 percent plus $0.30 per transaction. That means if you process a $100 payment, you pay $3.20 and receive $96.80. On a $1,000 payment, you pay $29.30 and receive $970.70. The percentage and flat fee both vary by processor and by how you accept the payment — online payments often cost less than in-person card swipes, and ACH bank transfers (moving money directly between bank accounts) usually cost less than card payments.
Some processors also charge a monthly account fee, a statement fee, or a gateway fee if you're using their software to collect payments. Others charge extra if a customer disputes a charge (a chargeback), which can run $15 to $100 per dispute. A few charge a fee just to keep the account open if you don't process any transactions in a month. Before signing up, ask for the full fee schedule in writing and calculate what you'll actually pay on your typical transaction size and volume.
Choosing between different types of processors
The right processor depends on how you take payments. If you sell online through a website, you need a processor that integrates with shopping cart software. If you take payments in person at a customer's home or office, you need one that works with a card reader on your phone. If you invoice customers and they pay later, you need one that handles recurring or scheduled payments. Some processors do all three; others specialize in one.
Third-party processors like PayPal, Square, and Stripe are the easiest to set up. You sign up online, connect your bank account, and start taking payments within days. They handle all the technical work and security. The trade-off is that their fees are usually higher than a dedicated merchant account, and they may freeze your account if they suspect fraud or if you're in a high-risk business (like property flipping or contractor work). They're best if you process small to medium volumes and want simplicity over cost.
Bank merchant accounts
Specialized processors focus on specific industries. Some handle real estate transactions, others focus on contractors or property management. They often include tools built for your business — like escrow handling, invoice templates, or tenant payment portals — but charge accordingly. If you're managing rental properties and collecting rent from multiple tenants, a processor built for property management may save time even if the per-transaction fee is slightly higher.
Security, fraud, and your responsibility
Your processor is responsible for detecting fraud and handling chargebacks, but you are responsible for following their rules. If you don't, you can lose your account or be held liable for fraudulent charges.
The main rule is PCI compliance — Payment Card Industry Data Security Standard. In plain terms, this means you cannot store customer credit card numbers on your own computer or in an email. If you take a card payment, the processor's system must handle the card data, not you. If you write down a card number or save it in a spreadsheet, you're breaking PCI rules and exposing yourself to liability if that data is stolen.
Most processors handle PCI compliance for you automatically — their payment form collects the card data, not you. But if you're using an older system or taking payments over the phone, you need to verify that your processor is PCI-compliant and that you're following their procedures. Ask your processor directly: "Am I PCI-compliant with the way I'm taking payments?" If the answer is unclear, you're not.
Chargebacks happen when a customer disputes a charge with their bank. The processor investigates, and if the bank sides with the customer, you lose the money and pay a chargeback fee. You can reduce chargebacks by sending clear invoices, keeping records of what you sold, and making your refund policy obvious. If a customer claims they never authorized a payment, your processor will ask for proof — a signed contract, an email confirmation, or a delivery receipt. Keep these records for at least a year.
How long it takes to receive money
The time between a customer's payment and money in your account varies by processor and payment method. Card payments typically take one to three business days. ACH bank transfers (direct from one bank account to another) take three to five business days. Some processors offer next-day or same-day deposits for an extra fee.
The clock starts when the transaction is complete, not when you initiate it. If a customer pays you on Friday evening, the processor may not process it until Monday morning, so you might not see the money until Wednesday or Thursday. If you need cash quickly — for example, if you're a contractor who has to pay suppliers before getting paid by the customer — ask your processor about expedited deposits or consider a processor that offers faster payouts, even if the fee is higher.
Some processors also hold a small percentage of your deposits in a reserve account for the first few months, releasing it gradually. This protects them if chargebacks come in later. Ask whether your processor uses a reserve and how long it lasts.
What happens if your processor closes your account
Payment processors can close your account without warning if they believe you're a fraud risk or if your business violates their terms. This is rare, but it happens. Contractors, real estate investors, and property managers sometimes get flagged because these industries have higher chargeback rates or because the processor's algorithm misinterprets normal business activity as suspicious.
If your account is closed, you lose the ability to take payments immediately. Any money in your reserve account may be held for 90 to 180 days while the processor investigates. You cannot easily move to another processor because the new one will see that you were terminated and may decline you as well.
To reduce the risk: keep your transaction history clean (low chargeback rate), respond quickly to any disputes, and follow the processor's rules exactly. If you're in a higher-risk business, choose a processor that specializes in your industry — they understand your business model and are less likely to flag normal activity as fraud. Also, do not rely on a single processor. If you can, set up accounts with two processors so you have a backup if one closes.
Comparing processors for your situation
Before choosing a processor, write down how you take payments: online, in person, by invoice, or a mix. Then list your typical transaction size and how many you process per month. A contractor processing five $5,000 invoices per month has very different needs than a property manager collecting $200 rent payments from 50 tenants.
Get the full fee schedule from at least three processors. Calculate what you'll pay per month on your actual volume. Don't just look at the percentage — the flat per-transaction fee matters more on small payments, and monthly fees matter more if you process a lot. Ask about chargeback fees, reserve policies, and how long deposits take. Read reviews from people in your industry, not generic reviews, because what works for an online store may not work for a contractor.
Also ask about customer support. If a payment fails or a customer disputes a charge, you need to reach someone who can help. Some processors offer phone support; others only have email or chat. If you're taking payments from customers who call you, you need a processor with phone support.
Frequently Asked Questions
Can I use the same processor for online and in-person payments?
Most major processors like Square, PayPal, and Stripe do both. You'll need a card reader (usually $20 to $100) for in-person payments, and the fees may differ slightly between online and in-person. Check the fee schedule for both before signing up to make sure the processor's rates work for your mix of payment types.
What's the difference between a processor and a payment gateway?
A processor moves the money; a gateway is the software that collects the payment information. Some companies do both. Others sell just the gateway software and partner with a processor behind the scenes. For most homeowners, this distinction doesn't matter — you just need to know the total cost and how long deposits take.
Do I need a business bank account to use a payment processor?
Most processors require a U.S. bank account in your name or your business name. A personal account works, but a business account is cleaner for record-keeping and taxes. Some processors also require a business license or tax ID, depending on your state and the processor's rules.
What happens if a customer does a chargeback?
The processor notifies you and asks for proof that the transaction was legitimate — an invoice, email confirmation, or signed contract. If you provide proof and the bank agrees with you, you keep the money. If the bank sides with the customer, you lose the money and pay a chargeback fee. You can dispute the chargeback, but the burden is on you to prove the customer authorized the payment.
Can I negotiate processor fees?
If you process high volumes (thousands per month), yes. Banks and some specialized processors will negotiate rates. If you're just starting out or processing small amounts, you have little leverage. Your best option is to shop around and choose the processor with the lowest total cost for your specific situation.
