Best Payment Processor for Small Business
Reviewed by The NetFee Tools Editorial Team · Last updated 2026-11-07
There is no single best processor for every US small business. This guide gives you a neutral, fee-based framework for choosing between Stripe, PayPal, and Square — using only verifiable standard online rates, not paid rankings.
The short answer
If you sell online in the US and have no negotiated pricing, the standard headline rates are close: Stripe 2.90% + $0.30, Square 2.90% + $0.30, and PayPal 3.49% + $0.49 per transaction. On a $100 charge that is $3.20, $3.20, and $3.98 respectively. A difference of a few cents per transaction rarely decides the choice — how you sell, your average ticket size, and the tools you already use matter more. Use the comparison calculator with your own numbers before deciding.
Why we do not publish a ranking
A “best” list implies we have tested every provider across support quality, payout timing, disputes, hardware, and account stability. We have not, and we will not invent those comparisons. What we do publish is a narrow, verifiable dataset: one standard US online rate per processor, each with an official source, an evidence grade, and a verification date. See the fee data pages and our methodology for exactly what is and is not covered.
A fee-based decision framework
- Start with your average ticket size. The fixed per-transaction fee is proportionally much larger on small payments. On $5, a $0.30 fixed fee is already 6% of the charge before the percentage is applied. If you sell many low-value items, run the any-rate calculator at your real average ticket rather than at $100.
- Check which channel you actually use. Our figures are US standard online rates. Card-present (in-person) pricing is different for all three providers and is outside this dataset — do not use these numbers to price a counter or market stall.
- Use the rate on your own agreement. Volume pricing, custom contracts, international cards, and add-on products change the effective cost. The comparison tool is a starting point, not a quote.
- Decide who absorbs the fee. In the US the merchant normally receives the charge minus the fee. If you plan to surcharge or set a minimum, check current state law and card-network rules first; this site does not provide legal advice. To price a fee in without losing margin, read how much to charge to cover fees.
- Then weigh non-fee factors yourself. Payout speed, invoicing, checkout UX, integrations, and support are real differentiators, but verify them on each provider’s official site — they change and we do not audit them.

Is there a cheapest payment processor?
On this one narrow rate, Stripe and Square are identical and PayPal is higher. That does not make either one the cheapest payment processor: total cost also depends on in-person volume, international cards, refunds, chargebacks, add-ons, and any negotiated rate. A provider with a lower headline rate can cost more once those are included. For a quick like-for-like check, put your own amounts into the comparison calculator. To understand what sits inside the rate at all, read payment gateway fees vs processing fees.
