Frequently asked questions
What is the cheapest payment processor for a small business in 2026?
By effective rate on a typical $25.00 small-business sale, the cheapest flat-rate processor we track is GoCardless at 2.00% (1.00% + $0.25). GoCardless is the cheapest with no monthly fee. Interchange-plus options like Helcim can be cheaper still as your volume grows. Snapshot June 2026 — processors change pricing; verify on the provider's pricing page before relying on a figure.
Why does the average ticket size change which processor is cheapest?
The fixed per-transaction fee (e.g. $0.30) is a bigger share of a small sale than a large one. On a $5 coffee, a $0.30 fixed fee alone is 6%; on a $200 order it is 0.15%. So low-ticket merchants should favor processors with a small fixed fee, and high-ticket merchants should favor a low percentage.
Is a no-monthly-fee processor always cheaper for a small business?
Usually yes for low volume. A $25-$99/mo subscription only pays off once the percentage savings exceed the fee — typically above $15,000-$20,000 in monthly card volume. Below that, a pay-as-you-go flat-rate or no-monthly interchange-plus processor (Stripe, Square, Helcim) is cheaper.
