The answer, as recorded
Here's who I'd actually point you to, roughly in order: **1. Square - the default for most small businesses, especially in-person.** No monthly fee, free POS app, hardware you can buy as you need it, invoicing and ACH included. Flat 2.6% + 15¢ in person, ~3.3% + 30¢ online. The flat rate isn't the cheapest, but setup takes an afternoon and you'll never get a surprise statement. Best if you're under roughly $10-25K/month. **2. Stripe - if you're online-first or selling software/subscriptions.** 2.9% + 30¢ online, ACH at 0.8% capped at $5, no monthly fee. Best developer tooling and documentation of anyone, strong international support, excellent recurring-billing handling. Overkill if you just need to swipe cards at a counter. **3. Helcim - the one to switch to once you have real volume.** Interchange-plus pricing instead of flat rate, so you pay actual card-network cost plus a small fixed markup. Effective rates average ~1.93% + 8¢ in person and ~2.49% + 25¢ online, and the markup drops automatically as volume grows. No monthly fee, no contract. Typically 20-40% cheaper than Square or Stripe above ~$5-10K/month. This is my pick if you're processing $10K+/month and willing to read a statement. **4. Stax - worth a look above ~$50K/month.** Subscription pricing: you pay a flat monthly membership and get interchange with near-zero markup per transaction. The math only works at high volume, where the membership fee gets amortized away. **5. PayPal - not as your primary processor, but add it as a checkout option.** Conversion lift from buyers who already have an account is real. Rates are mediocre (~3.49% + 49¢ for some flows) and account holds are a known headache, so don't make it your only rail. **Quick version:** brand-new or under $10K/month → Square (or Stripe if you're online-only). Over $10K/month → move to Helcim and stop donating the difference. Over $50K → price Helcim against Stax. One caveat on all of these: anything "free" with no monthly fee is making its money on the spread, so compare *effective rate* (total fees ÷ total volume) from an actual month of your own statements rather than headline rates. And be skeptical of any processor pitching you a multi-year contract with early-termination fees - none of the four above require one.
