Stripe vs Square vs PayPal: Fees Compared for US Small Businesses (2026)

Payment fees are the one software cost that grows with every sale. A small difference in rate, a fixed fee per transaction or a forgotten dispute charge can cost a small business hundreds or thousands of dollars a year. Stripe, Square and PayPal are the three processors US small businesses compare most, and each one is built around a different kind of seller. This guide compares their published US fees line by line, checked on the official pricing pages on November 13, 2026, with worked examples for online stores, in-person sellers and service businesses that invoice.

How the Three Processors Differ

• Stripe is a developer-first payments platform. It powers online checkouts, subscriptions, marketplaces and in-person payments through Stripe Terminal, with an API at its core. It suits businesses that sell online or build their own software.
• Square is a complete point-of-sale and business toolkit. Payments come with a POS app, online store, invoicing, bookings, payroll and banking, with plans from free to $149 a month per location. It suits restaurants, retail shops and service businesses that meet customers face to face.
• PayPal is both a consumer wallet and a merchant processor. Its main advantage is the PayPal and Venmo accounts customers already have. It also offers card processing, invoicing, a point-of-sale app and payouts.

The Comparison Table

Square ranks first overall because most small businesses take at least some payments in person. For a business that sells only online, Stripe moves to first place.

Fees Side by Side

All rates are US domestic rates as published on November 13, 2026.

Online card payments

Bank payments, invoices and subscriptions

In-person payments

Disputes, payouts and monthly fees

Two rules catch many sellers. With PayPal, refunding a payment costs nothing, but "the fees you originally paid to receive the payment are not returned to you." Stripe's standard dispute fee is charged for each dispute received, while Square lists chargebacks among the things it does not charge for.

What You Actually Pay: Three Examples

An online store selling a $50 product

On pure card payments, Stripe and PayPal's advanced card processing cost almost the same. The real difference comes from how many customers choose to pay with their PayPal or Venmo account, which costs 3.49% + 49¢. Many stores offer both: Stripe or advanced cards for card payments, and PayPal as an option for customers who prefer it.

A cafe or shop selling a $30 order in person

On fees alone, PayPal's point-of-sale rate is the lowest. Most in-person businesses still choose Square because the fee is only part of the cost. Square includes a full POS app, inventory, online ordering, staff tools and offline payments, and it does not charge for chargebacks. Square's paid plans make sense when you use their extra features, not to save on rates.

A service business sending a $1,000 invoice

For high-value invoices, asking clients to pay by bank transfer cuts fees by 65% to 85%. Stripe's $5 cap on ACH payments is the lowest of the three.

Processor by Processor

Stripe

Stripe is the strongest platform for online businesses. One flat rate covers domestic cards, there is no monthly fee on standard pricing, and the same account handles subscriptions through Stripe Billing, invoices, payment links, marketplaces and in-person payments with Stripe Terminal. The API and documentation make it the default choice for software companies and for any business that wants a custom checkout.

Strengths:

• Flat 2.9% + 30¢ online with no monthly fee.
• Subscriptions, invoicing and usage-based billing in the same account.
• ACH payments capped at $5, the lowest cap of the three.

Limits:

• A $15 fee for every dispute received, plus $15 to counter it.
• In-person selling needs Stripe Terminal readers and a POS app built on top.
• Setup for advanced features usually needs a developer or a no-code tool.

Best for: online stores, SaaS and subscription businesses, marketplaces and agencies that bill clients online.

Square

Square is the easiest way to start taking payments in person and online in the same system. The free plan includes the POS app, an online site, an item library, invoicing and bookings, and you pay only when you take a payment. Plus at $49 and Premium at $149 per location lower card rates and add advanced features by industry, from kitchen display systems to inventory and staff management. Every plan includes encrypted payments, fraud prevention, next-day transfers and offline payments.

Strengths:

• A free plan with POS, online store, invoicing and bookings.
• No fees for chargebacks and dispute management.
• Affordable hardware, from a $59 reader to a $299 terminal with a receipt printer.

Limits:

• The online rate on the free plan is 3.3% + 30¢, higher than Stripe's.
• Keyed-in payments cost 3.5% + 15¢.
• Lower rates require a paid plan per location.

Best for: restaurants, cafes, retail shops, salons and service businesses that sell face to face.

PayPal

PayPal's strength is its brand. Customers who already have PayPal or Venmo accounts can pay in two clicks, which can increase checkout completion. For card payments, PayPal's advanced card processing at 2.89% + 29¢ is slightly cheaper than Stripe on small orders, and its point-of-sale rate of 2.29% + 9¢ is the lowest in-person rate of the three.

Strengths:

• PayPal and Venmo checkout trusted by many shoppers.
• Competitive advanced card rate and the lowest in-person rate.
• Pay Later at 4.99% + 49¢, below Klarna on Stripe and Afterpay on Square.

Limits:

• PayPal Checkout and Venmo payments cost 3.49% + 49¢.
• A $20 chargeback fee on card transactions, and dispute fees up to $30 for high-volume sellers.
• Fees are not returned on refunds, and currency conversion spreads reach 3% to 4%.

Best for: online sellers whose customers expect PayPal or Venmo, marketplaces and freelancers paid by international clients, and as a second payment option next to Stripe or Square.

Which Processor Fits Which Business

• An online store: Stripe for cards, with PayPal added as a checkout option.
• A SaaS or subscription business: Stripe with Stripe Billing.
• A restaurant or cafe: Square, or a dedicated restaurant POS. See our Square vs Clover vs Toast comparison.
• A retail shop selling in store and online: Square.
• A consultant or agency invoicing clients: Stripe invoices with ACH to keep fees under $5 on large invoices.
• A freelancer paid by clients abroad: PayPal or Stripe, comparing currency conversion costs on your typical amounts.

Many businesses use two. A common setup is Square at the counter and Stripe online, or Stripe for cards with a PayPal button at checkout.

The Hidden Costs Checklist

The headline card rate rarely tells the whole story. Before you sign up, check each of these lines against your own sales:

Two patterns stand out. Square keeps the payment side simple and charges for software per location. PayPal's base rates are competitive, but optional tools and conversion spreads add up quickly for international sellers. Stripe sits in between, with very few fixed fees and a small charge on most extras.

Questions to Ask Before You Switch

1. 1 What share of my sales is online, in person and invoiced? The answer decides which rate table matters most.
2. 2 What is my average ticket? Fixed fees of 30¢ or 49¢ hurt small orders; percentage rates matter more on large ones.
3. 3 How many disputes do I get each year? At $15 to $30 each, ten disputes a month cost more than a premium plan.
4. 4 Do my customers ask for PayPal or Venmo? If yes, offer it, even if cards go through another processor.
5. 5 Which accounting and booking tools must connect? Check the integrations you rely on before moving any payment flow.

How to Lower Your Processing Fees

1. 1 Push large payments to ACH. Stripe caps ACH at $5 and PayPal online ACH at $5.
2. 2 Avoid keyed-in payments. Manual entry adds 0.5% on Stripe and costs 3.5% + 15¢ on Square.
3. 3 Use payment links instead of typing card numbers for phone orders.
4. 4 Reduce disputes with clear descriptors on bank statements, fast refunds and delivery confirmation.
5. 5 Skip instant payouts unless you need the cash that day. They cost 1.5% to 1.95%.
6. 6 Ask for custom pricing above $250,000 a year. Square offers custom rates above that volume, and Stripe and PayPal also negotiate at scale.

Automations Around Your Payments

Payment processors leave plenty of manual work: reconciling payouts, chasing failed payments and copying sales into accounting. These are workflows we build with n8n:

1. 1 Failed payment recovery: when a card fails on a subscription or invoice, the customer gets a reminder with a secure update link.
2. 2 Accounting sync: payouts, fees and refunds are recorded in QuickBooks or Xero with the right categories, so fees show up as expenses.
3. 3 Dispute alerts: a new dispute opens a task with the order details and the evidence deadline.
4. 4 Daily revenue summary: sales by channel, fees paid and refunds sent each morning to the owner.
