Top Payment Apps for Small Business

By Tap Simple Editorial Team · Updated September 30, 2026

The first question to ask about payment apps for small business is how much you want to pay for your transactions. After that, the right choice is the one that fits how you sell: at a counter, on a job site, at a market stall or over the phone. A good payment app for business is clear about how it charges to process each card payment, takes cards and mobile wallets and works with the hardware you already have. Tap Simple is the better choice for many small businesses because it pairs the Payanywhere app and a 3-in-1 Reader with terminals for every setup, one Payments Hub dashboard, a cash discount program and support you can reach directly. This guide covers what to check, starting with what you pay to process, how Tap Simple works, and how it compares with Square, PayPal, Stripe and Venmo.

What to Look for in Payment Apps for Small Business

Payment apps for small business look alike at first glance, so start with what each one charges to process your transactions, then compare ease of use, security, hardware and support.

What You Pay to Process Transactions

Find out exactly how each app charges to process card payments before you sign up, along with any software and hardware costs. Some charge a cut of every sale, some add monthly software plans and some sell hardware separately. Our guide to how card processing fees work explains the common models. Tap Simple offers a cash discount program.

Ease of Use

You and your staff should be able to ring up a sale, add a tip and issue a refund without hunting through menus. Clear screens cut down on mistakes and shorten training. The Payanywhere app that runs Tap Simple’s 3-in-1 Reader includes preset tip amounts, on-screen signatures, tickets and tabs, and a Terminal or Retail theme, so the screen matches the way you sell.

Security

A secure payment app encrypts card data, supports EMV chip and contactless payments, and helps you meet the Payment Card Industry Data Security Standard (PCI DSS). Staff permission levels add another layer of protection. The Tap Simple 3-in-1 Reader accepts EMV chip cards and NFC contactless payments, including mobile wallets, as well as magstripe.

Hardware Compatibility

Check that the app runs on the phone or tablet you already have and grows with you. The Tap Simple 3-in-1 Reader pairs with a compatible iOS or Android phone or tablet over Bluetooth, and all Tap Simple hardware works together through Payments Hub, so a reader at an off-site event sees the same inventory count as your store.

Customer Support

When a payment will not go through during a rush, you need a person to contact. Find out which support channels each provider offers before you sign up. You can reach Tap Simple support by email at support@tapsimple.com or by phone at +1 (563) 580-4493.

How Tap Simple Works as a Payment App for Business

Tap Simple is our product, and we list it first because it gives you a payment app for business and a complete processing setup from one provider: the app, the reader, the terminals, the dashboard and the support line.

• The app and reader. The 3-in-1 Reader pairs with a compatible iOS or Android phone or tablet over Bluetooth and works with the Payanywhere app. It accepts EMV chip, magstripe and NFC contactless payments, including mobile wallets, and the app supports offline payments.
• The dashboard. Payments Hub adds real-time sales, item, customer and employee data, reports you can sort, filter, compare and export, a virtual terminal for keyed-in or card-on-file payments, email or SMS invoices with recurring billing and autopay, and dispute management.
• Room to grow. When you want a dedicated device, the Smart Terminal adds a handheld with a built-in receipt printer and 4G and Wi-Fi, and the Smart Flex adds a countertop screen with a customer-facing display. Both report to the same Payments Hub account. For hardware details, see our guide to the best credit card machine for small business.

Tap Simple vs Square, PayPal, Stripe and Venmo

Square, PayPal, Stripe and Venmo are well-known names in payment apps, and each takes a different approach. The table uses tapsimple.com plus Square’s Tap to Pay page, PayPal’s point of sale page, Stripe’s Tap to Pay page and Venmo’s business profile page, all checked September 30, 2026. Competitor pricing is described in words only. If you are weighing Square in particular, see how Square works for small businesses.

Things to know	Focused on payment processing rather than a full retail or restaurant software suite	Tap to Pay on iPhone needs an iPhone XS or later	Funds settle into a PayPal business account	Requires integrating Stripe Terminal into an app	Business profiles are managed only in the app, and only the creator can log in

Where Tap Simple Stands Out

Tap Simple stands out when you want the app, the reader, the terminals and the processing from one provider. Every device reports to one Payments Hub, you get invoices and a virtual terminal alongside in-person sales, Tap Simple offers a cash discount program, and you can call or email support directly. The others each do something well, from Square’s hardware range to PayPal’s QR codes, and the table above notes where each one shines.

Who Each Fits

Each payment app fits a different kind of business, based on the features each company publishes:

• Tap Simple fits small businesses that want a phone reader today, room to add terminals later, one dashboard, a cash discount program and direct support.
• Square fits sellers who want a broad set of Square software and hardware in one ecosystem.
• PayPal POS fits sellers whose customers already pay with PayPal or Venmo and who keep funds in a PayPal business account.
• Stripe fits businesses and platforms that build their own app and want to add in-person payments to it.
• Venmo business profile fits sole proprietors and side businesses whose customers already use Venmo.

If you are weighing full processors rather than apps alone, our guide to the best credit card processing for small business walks through what to check.

Matching a Payment App to How You Sell

Once you know what you want to pay to process, the right payment app depends on where your sales happen and how your customers like to pay. Here is how Tap Simple fits each setup.

Storefronts and Counters

A shop, café or salon needs item lists, tips, receipts and a reader or terminal on the counter. The 3-in-1 Reader turns a tablet into a counter checkout, the Smart Terminal adds a built-in receipt printer, and the Smart Flex gives customers their own display.

Online Sales and Invoicing

If you bill after the work is done or take orders by phone, you need invoices and a virtual terminal. Payments Hub includes email or SMS invoices with recurring billing and autopay, plus a virtual terminal for keyed-in payments, all in the same dashboard as your in-person sales.

Your Customers’ Payment Preferences

If your customers tap a phone or watch to pay, you need contactless payments and mobile wallets, which the 3-in-1 Reader accepts; our guide to the benefits of contactless payment explains why that matters. If some customers still prefer cash, the Tap Simple cash discount program lets you reward them.

Payment Apps for Service Businesses and Mobile Sellers

A payment app for service businesses has to work wherever the job is, not just at a counter. Picture a mobile cleaning company with two crews: one crew finishes a house clean and takes a tap payment on the driveway, the office sends a recurring invoice to a weekly client, and a new customer calls in a deposit that the owner keys into the virtual terminal.

With Tap Simple, each crew pairs a 3-in-1 Reader with a phone, offline payments cover a job site with weak signal, Payments Hub handles the recurring invoice and the keyed-in deposit, and employee permission levels control what each crew can see. Every payment lands in the same report, so the owner sees the whole day in one place. Read more about mobile credit card processing and how Tap Simple supports field service businesses.

How to Get Started With Tap Simple

Getting started with Tap Simple takes five steps:

1. Apply online. Apply for a Tap Simple merchant account in one place. Every application is reviewed case by case. Our merchant account documents checklist shows what to have ready, and how to get a merchant account covers the rest.
2. Link your bank account. Deposits from card sales go to the account you connect, so double-check the details.
3. Pair your hardware. Download the Payanywhere app on a compatible phone or tablet and pair your 3-in-1 Reader, or power on your Smart Terminal.
4. Add your items and team. Enter items, staff and tip settings in Payments Hub so reporting works from day one.
5. Practice. Run a few practice sales, refunds and tips so everyone is comfortable before a busy day.
