The 9 Best Payment Apps for Small Business (2026)
Every payment app compared on the only number that compounds: the percentage it takes. Plus which ones are genuinely free and what you give up to use them.
Payment app comparisons usually rank on features. Features are roughly equivalent; fees are not, and fees compound. Here are nine ranked by what they cost on a $2,000 invoice, with what you give up for the cheap ones.
The ranking
| # | App | Fee | Cost per $2,000 |
|---|---|---|---|
| 1 | Bank transfer / ACH | $0 | $0 |
| 2 | PayID (AU) | $0 | $0 |
| 3 | Zelle (US) | $0 | $0 |
| 4 | Venmo business | 1.9% + $0.10 | $38.10 |
| 5 | Cash App for business | ~2.75% | $55.00 |
| 6 | Square | 2.6–2.9% + $0.30 | $52.30–$58.30 |
| 7 | Stripe | 2.9% + $0.30 | $58.30 |
| 8 | Apple Pay / Google Pay | underlying card rate | varies |
| 9 | PayPal | up to 3.49% + fixed | $70.30 |
1–3. The free rails, and what they cost you instead
Bank transfer, PayID and Zelle take nothing. What they cost is friction and record-keeping: none of them carry an invoice, so unless you send one separately you have no record of what the payment was for, and the client has nothing to check against. That is a bookkeeping problem, not a fee problem, and it is solved by sending a proper invoice with the payment details on it. See Zelle for business and PayID invoicing.
4. Venmo business — cheapest of the app rails
1.9% + $0.10 is materially cheaper than Square, Stripe or PayPal, and for younger US clients it is often the only thing they will use without complaint. Personal Venmo accounts are not for business use — the business account rules are here.
5. Cash App for business
Around 2.75%, same shape as Venmo, smaller reach. Setting it up for business.
6–7. Square and Stripe — you are buying infrastructure
Both about 2.9% + $0.30. Hosted checkout, disputes, recurring billing and reconciliation are real products, and if you take card payments in volume they pay for themselves. If you send a handful of invoices a month, you are renting infrastructure you barely use. Stripe's fees in detail.
8. Apple Pay and Google Pay
Not really separate rails — a wallet sitting on top of a card, charged at the underlying card rate. Convenient at checkout, no cheaper.
9. PayPal — the most expensive default
Up to 3.49% plus a fixed fee. Universally recognised, which is exactly why people never audit what it costs them.
The practical setup
Offer a free rail first and a card rail second, on the same invoice. Most clients take the first option presented; the ones who insist on cards still can. That single change moves the majority of your revenue off a percentage. Work out what it is worth to you with the fee calculator, or put your payment details on a free invoice and see how it reads.
