Stripe vs Square vs PayPal: the real fee tables

Every processor advertises one headline rate and hides the rest in a pricing page you have to scroll for. Here are the numbers that actually hit your bank account, for US accounts.

Stripe: 2.9% + 30¢ per successful online card charge. International cards add 1.5%. Currency conversion adds another 1% if you settle in a different currency. ACH direct debit: 0.8%, capped at $5. In-person (Terminal): 2.7% + 5¢. Micropayment pricing exists but is not public by default — you request it and it typically lands around 5% + 5¢, which only wins when your average transaction is under about $10. Instant payouts cost 1% of the payout amount.

Square: 2.9% + 30¢ online — matching Stripe — but in-person is 2.6% + 15¢ with no monthly fee, which is why Square dominates coffee shops and markets. Invoices: 3.3% + 30¢, noticeably worse than Stripe for invoice-heavy businesses. ACH via Square Invoices: 1% with a $1 minimum. International cards: +1.5% on top, same as Stripe. Square's hardware ecosystem (free magstripe reader, $49 contactless reader, full POS registers) is the real moat — if your money changes hands in person, Square's kit is the simplest path.

PayPal: 2.99% + 49¢ for standard online checkout — worse than Stripe on both the percentage and the fixed fee, which punishes small tickets twice. PayPal's advantage is buyer trust: hundreds of millions of accounts, and customers who refuse to type card numbers into unfamiliar sites will still click the yellow button. Payouts to your bank are free on the standard 1–3 day schedule; instant transfer to a debit card costs 1.75%. PayPal's dispute process historically favors buyers more aggressively than Stripe's, which matters if you sell digital goods.

The math that matters is your effective rate: total fees paid divided by total volume processed, over a real month. A flat 2.9% + 30¢ on fifty $10 sales is an effective rate of 5.9% — the fixed 30¢ dominates. On ten $500 sales it is 2.96%. Same processor, wildly different cost. That is why "which is cheapest" has no universal answer — it depends on your average ticket size, your in-person versus online split, and how many of your cards are international.

When each processor wins

Forget "best processor" — match the tool to how money actually reaches you. Four common shapes:

Online checkout (courses, e-commerce, SaaS): Stripe wins. Its checkout pages, subscription billing, and developer tooling are the deepest in the industry, and the API lets you build exactly the purchase flow you want instead of accepting a generic button. PayPal belongs here too, but as a second option — offer the PayPal button alongside cards for the trust bump, not as your only rail.

In-person sales (markets, studios, pop-ups): Square wins. The free reader in your pocket, the $49 contactless reader on the counter, and a point-of-sale app that tracks inventory without a separate system — nobody else bundles hardware and software this tightly. Stripe Terminal exists and is competent, but you are assembling the kit yourself.

Invoicing (freelancers, agencies, B2B): Stripe and Square both work; pick on fees. Square invoices cost 3.3% + 30¢ on cards versus Stripe's 2.9% + 30¢, so Stripe wins on cards — but if your invoices are large, offer ACH on Stripe at 0.8% capped at $5 and the card question mostly disappears. PayPal invoicing is fine for clients who insist on paying through their PayPal balance.

Marketplaces and platforms (you pay out sellers, coaches, or creators): Stripe Connect is the only serious answer among the three. It handles the hard parts — onboarding sellers with their own KYC, splitting a payment between you and a seller, issuing 1099s, and keeping everyone's money legally separate. Square and PayPal have no equivalent product at this depth. If your business model involves paying other people, the decision is made for you.

The hybrid answer is legal and common: Stripe for online, Square for in-person, PayPal as a checkout option. You are not marrying one processor. You are assembling a stack, and each piece should earn its place on fees for the volume it handles.

Account setup, step by step — and the KYC gauntlet

Setting up a processor account is really two things: creating the account (ten minutes) and passing identity verification (the part that freezes payouts when it goes wrong). Do it in this order, once, correctly.

Step 1 — Business details. Legal business name exactly as registered, entity type (LLC, corporation, sole proprietorship), and EIN for entities or SSN for sole proprietors. The name must match your tax documents character for character — "Fluent Collective LLC" versus "Fluent Collective" is enough to trigger a manual review.

Step 2 — Beneficial owners. Federal rules require every individual who owns 25% or more of the business, plus one person with significant control, to be listed with full legal name, date of birth, address, and the last four of their SSN. This is the step founders skip or fudge, and it is the number-one cause of verification holds. List everyone; partial disclosure fails harder than full disclosure.

Step 3 — Bank account. Connect the business checking account where payouts land. Use a real business account, not a personal one — processors flag personal accounts on business profiles during reviews. Micro-deposit verification takes one to two business days if instant bank linking fails.

Step 4 — Business website and description. You must describe what you sell and provide a working website. "Coming soon" pages and vague descriptions ("consulting services") are the top triggers for manual review. Write one plain sentence: "We sell a 60-day online fitness program for $149." Link a live page showing the product and a refund policy.

What triggers reviews and reserves: sudden volume spikes (10x your normal week), high refund or dispute rates (above roughly 1% of volume), selling in a restricted category, or mismatched business details. A review usually means payouts pause for a few days while documents are checked; a reserve means the processor holds a percentage of each payout (commonly 5–10% for 90–120 days) as a buffer against disputes. Both are survivable if you expect them. Neither is survivable if that payout was covering payroll Friday.

• Legal business name matches tax documents exactly
• EIN (or SSN for sole proprietors) on hand
• All beneficial owners (25%+) listed with DOB, address, SSN last-four
• Business checking account connected (not personal)
• Live website with product description and refund policy
• Payout schedule reviewed and cash-flow buffer planned

Payout schedules, instant payouts, and reserves

Getting paid by customers and getting paid by your processor are two different events, days apart. This lesson is about the second one — because cash flow lives or dies here.

Standard payouts: the 2-day rolling schedule. Stripe's default US schedule pays out your available balance on a rolling two-business-day delay: Monday's sales arrive Wednesday, Tuesday's arrive Thursday, and so on. Weekends and bank holidays shift everything — Friday's sales land Tuesday. Your first payout always takes longer (seven to fourteen days) while the account finishes verification; plan your launch cash accordingly. Square defaults to next-business-day, PayPal to one to three business days on the free transfer. None of these are negotiable for new accounts.

Instant payouts: speed at 1%. Stripe lets you push available funds to an eligible debit card within minutes for a 1% fee. Square offers instant transfer at 1.75%; PayPal's instant transfer to debit is also 1.75%. The math: on a $10,000 payout, instant costs you $100 on Stripe. Worth it for a genuine emergency — covering payroll, seizing a same-day ad opportunity — and a terrible habit as a routine. If you need instant payouts weekly, your cash buffer is the problem, not the schedule.

Reserves: the processor's insurance policy. If your business looks risky (high-ticket items, pre-orders with long fulfillment, elevated disputes), the processor may hold a rolling reserve — typically 5–10% of each payout, released after 90–120 days — or a fixed minimum balance. Reserves are not fines and not negotiable in the moment; they release automatically as the holding period passes without disputes. The defense is boring: keep dispute rates under 1%, fulfill fast, and keep six weeks of operating cash so a reserve never threatens operations.

The payout calendar habit: write down your processor's schedule, map which sales days fund which bank deposits, and reconcile weekly. The founders who get blindsided are the ones who mentally spent Monday's revenue on Tuesday. Money in your Stripe balance is not money in your bank — treat the gap as sacred.
