How to Choose a Payment App That Fits Your Business
What "best" means depends on what you're selling and how you sell it
There is no single best payment app. The right one for you depends on whether you take payments in person, online, by invoice, or all three—and what you pay in fees matters more than the app's name. A Square reader works differently than a PayPal invoice link, which works differently than a Stripe terminal. Each one connects to your bank account, but they move money at different speeds, charge different percentages, and work with different types of sales.
This guide walks you through the real differences: what each type of app does, what it costs, and how to match one to the way you actually run your business. The goal is to understand your options clearly enough to make a decision that doesn't leave you paying more than you have to.
Key Takeaways
- In-person payment readers (Square, Clover, Toast) charge a percentage per transaction plus a small flat fee, while online payment links (PayPal, Stripe) charge a similar percentage but work differently for invoices and recurring billing.
- Processing fees range from roughly 2.5% to 3.5% for card payments, but the exact rate depends on whether the card is present, whether it's a business or consumer card, and the app's pricing tier.
- Settlement speed varies: some apps deposit money the next business day, others take two to three days, and this affects your cash flow if you need money quickly.
- Most apps charge extra for features like invoicing, recurring billing, or detailed reporting, so compare what's included in the base plan versus what costs extra.
- Your bank account and tax ID are required to set up any payment app, and the app will report your transactions to the IRS on a 1099-K form.
In-person payment readers: how they work and what they cost
An in-person payment reader is a small device that connects to your phone or tablet. You swipe, tap, or insert a customer's card, and the app processes the payment. Square Reader, Clover, Toast, and Ingenico all work this way. The device itself is usually free or costs $20 to $100 depending on the model and the app.
Fees for in-person payments typically run 2.5% to 2.75% of the transaction amount plus $0.10 to $0.30 per transaction. Some apps charge less if you use their own branded card reader; others charge the same rate regardless. A $100 sale might cost you $2.50 to $2.75 in fees. The money usually lands in your bank account the next business day, though some apps offer same-day settlement for an extra fee.
Most in-person apps include a basic point-of-sale system—a digital register that tracks sales, inventory, and customers. Invoicing, recurring billing, and detailed reporting often cost extra or are only available on higher-tier plans. If you run a small business and take most payments face-to-face, an in-person reader is usually the most straightforward choice.
Online payment links and invoicing: for remote and recurring sales
Online payment apps like PayPal, Stripe, and Square Online let you send a payment link to a customer via email or text. The customer clicks the link, enters their card details, and pays. You never touch their card information. These apps are built for invoicing, one-time purchases, and recurring billing like subscriptions.
Online payment fees are similar to in-person fees—usually 2.9% to 3.5% plus $0.30 per transaction—but the rate can be higher because the card is not physically present. Some apps charge less if you use their invoicing feature directly rather than a custom link. Recurring billing (charging a customer the same amount every month) may have its own fee structure or may be included in the base plan.
Settlement is usually one to three business days. Some apps let you connect a PayPal or Stripe account to your existing website, which means you don't need to send a link—customers pay directly on your site. If you invoice clients, run a subscription service, or sell online, an online payment app is the right fit.
Comparing fees across different transaction types
The fee you pay depends on how the card is processed. A card that is physically present and swiped or tapped costs less than a card that is entered manually or processed online. A business credit card may cost more than a consumer card. Debit cards sometimes cost less than credit cards. The app's pricing tier also matters: a basic plan might charge 2.9%, while a premium plan charges 2.6%.
To compare apps fairly, look at the rate for the type of transaction you do most often. If you take 80% of your payments in person with a card reader, the in-person rate matters most. If you invoice clients, the online rate matters most. Don't compare an in-person rate to an online rate and assume they're the same—they're not.
Some apps charge monthly minimums or monthly fees for features. Square charges nothing monthly for the basic plan but charges $60 to $300 per month for higher tiers. Stripe has no monthly fee but charges per transaction. PayPal charges per transaction and per invoice. Add up the fees you'd pay in a typical month, not just the per-transaction rate, to see the real cost.
Settlement speed and how it affects your cash flow
Settlement is the day the money actually lands in your bank account. Most apps settle the next business day, but some take two to three days. If you process $1,000 on a Monday, you might see it Tuesday (next-day settlement) or Wednesday or Thursday (two- to three-day settlement). The difference matters if you need cash quickly to pay suppliers or payroll.
Some apps offer same-day or instant settlement for an extra fee—usually 1% to 2% of the transaction amount. That means you pay more to get the money faster. If you rarely need money the same day, the extra fee isn't worth it. If you do, compare the cost of instant settlement across apps before you choose.
Weekend and holiday transactions usually settle on the next business day, not the next calendar day. A payment processed on Friday might not settle until Monday. Check the app's settlement policy before you sign up, especially if you run a weekend business.
What features are included and what costs extra
Most payment apps include basic transaction processing and a simple sales record. Beyond that, features vary. Invoicing, recurring billing, customer management, inventory tracking, detailed reporting, and staff accounts often cost extra or are only available on paid plans.
Square's basic plan is free and includes a point-of-sale system and basic reporting. Invoicing and recurring billing are free. Detailed analytics and staff accounts cost extra. Stripe's basic plan charges per transaction and includes invoicing and recurring billing at no extra cost. Clover's basic plan is free but charges for most features beyond basic payment processing. PayPal's basic plan charges per transaction and includes invoicing; recurring billing is free.
Before you choose an app, list the features you actually need—not the ones that sound nice. If you don't invoice, invoicing features don't matter. If you don't track inventory, inventory features don't matter. Paying for features you don't use is the most common way people overpay for a payment app.
How payment apps report your income to the IRS
Every payment app reports your transactions to the IRS on a Form 1099-K. The form shows the total dollar amount you processed in a year. The threshold for receiving a 1099-K varies by year and by state, but it's typically $20,000 and 200 transactions, or $5,000 in some states. If you cross that threshold, you'll receive the form in January and the IRS receives a copy too.
The 1099-K reports gross transaction volume, not profit. If you processed $50,000 in sales but spent $30,000 on inventory, the 1099-K shows $50,000. You report your actual profit on your tax return. Keep records of your expenses so you can deduct them when you file. The payment app itself does not calculate your taxes—that's your responsibility or your accountant's.
Some payment apps let you download transaction reports and export them to accounting software like QuickBooks. Others require you to download a CSV file and import it manually. If you use accounting software, check whether the payment app integrates with it before you sign up.
Frequently Asked Questions
Can I use more than one payment app at the same time?
Yes. Many businesses use a card reader for in-person sales and a payment link for invoices. Each app connects to your bank account separately, and each reports its own transactions to the IRS. Using multiple apps is fine as long as you track which transactions came from which app so you don't double-count income.
What happens if a customer disputes a charge?
The payment app holds the disputed amount while the customer's bank investigates. If the bank rules in the customer's favor, the money is returned to them and deducted from your account. If the bank rules in your favor, you keep the money. Most apps charge a dispute fee ($15 to $25) whether you win or lose. Keep receipts and transaction records to defend yourself if a dispute happens.
Do I need a business bank account to use a payment app?
No, but most payment apps require a bank account in your name and a tax ID. Some apps accept sole proprietors with a personal bank account and an SSN. If you operate as an LLC or corporation, you typically need a business bank account and an EIN. Check the app's requirements before you start the setup process.
What if I want to switch payment apps later?
You can switch at any time. Your old app keeps the transaction history, and your new app starts fresh. The only thing that doesn't transfer is your customer list or saved payment methods—you'll need to ask customers to re-enter their information or re-send invoices through the new app. There's no penalty for leaving, but there's also no way to move your history automatically.
Which app is cheapest?
It depends on your transaction type and volume. For in-person sales under $10,000 per month, the difference between apps is usually $20 to $50 per month. For online invoicing, the difference is smaller. Calculate your actual fees for a typical month using each app's pricing, then choose based on cost plus features you need. The cheapest app isn't always the best if it's missing a feature you rely on.
