The answer, as recorded
Here's who I'd actually name, roughly in the order I'd bring them up: **1. Square - the default for most small businesses.** No monthly fee, free card reader, flat ~2.6% + $0.10 in person, and you get POS, invoicing, online store, and payroll add-ons in one account. If you're under roughly $25-50K/month in volume and don't want to think about payments, start here and stop reading. **2. Stripe - the default if you're selling online or have a developer.** Flat 2.9% + $0.30 online, best-in-class API and docs, strong subscriptions/billing. It's the industry standard for custom checkouts and SaaS. Weaker as a physical-retail POS than Square. **3. Helcim - the one to switch to once volume grows.** Interchange-plus pricing (~IC + 0.40% + $0.08 in person, IC + 0.50% + $0.25 online) with no monthly fee, and rates drop automatically as you scale. This is the pick once you're past ~$25-35K/month, where flat-rate pricing starts quietly overcharging you. Genuinely transparent, which is rare in this industry. **4. PayPal (incl. Venmo/Pay Later) - as a secondary option, not your main processor.** Fees are unremarkable and account holds are a real risk, but the checkout conversion lift from buyer familiarity is real. Worth having alongside Stripe or Square rather than instead of. **5. Stax - only if you're high-volume.** $99/month subscription plus interchange and $0.08-$0.18 per transaction. The flat monthly fee only pays off somewhere in the $50-80K+/month range; below that it's worse than Helcim. **6. Airwallex - if you sell across borders.** Multi-currency settlement in 20+ currencies, so you avoid the forced FX markups Stripe and PayPal take on conversions. Overkill for a domestic-only business. Two practical notes: treat the volume thresholds above as rules of thumb, not precise numbers - your real cost depends heavily on card mix (rewards and business cards carry higher interchange) and average ticket size, so a low-ticket, high-count business behaves very differently than one with $500 invoices. And be skeptical of the comparison sites in this space generally; most earn affiliate commissions on the providers they rank. The reliable move is to take one month of your own statements and ask two providers to quote against it.
