The answer, as recorded

Here's how I'd actually rank these, since "best" depends mostly on how you sell and how much you process: **1. Square - the default if you sell in person.** Free POS software, free/cheap readers, no monthly fee, and you can be taking cards the same day. 2.6% + 10¢ in person, 2.9% + 30¢ online. Nothing else gets a retail shop, café, or market stall running faster, and the hardware-plus-software bundle means you're not stitching together three vendors. **2. Stripe - the default if you sell online or you're building something custom.** 2.9% + 30¢ online, best-in-class API and docs, and it handles subscriptions, invoicing, marketplaces, and international cards without you leaving the platform. The tradeoff: it's developer-first, so if nobody on your side writes code you'll feel it. **3. Helcim - the one to switch to once you're past roughly $10-15K/month.** It's interchange-plus rather than flat-rate, with automatic volume discounts, averaging ~1.83% + 8¢ in person and ~2.27% + 25¢ online, and still $0/month. At flat-rate you pay the same markup on a $5 coffee and a $5,000 invoice; Helcim is where that stops. Less polished onboarding than Square, but the savings at volume are real. **4. PayPal - not as your main processor, but as a checkout option.** Worth adding because a chunk of buyers trust the button and will convert on it when they won't hand over a card. Its standard online rate is in the same 2.9% + 30¢ neighborhood, so it's not a cost win - it's a conversion win. **5. Shopify Payments - only if you're already on Shopify.** Integrated rates, one dashboard, and Shopify penalizes you with an extra fee for using an outside processor, so the decision is effectively made for you. **6. Adyen or Finix - ignore these until you're genuinely big.** Adyen runs payments for Netflix, Uber, and Microsoft; Finix is for companies embedding payments into their own product. Great platforms, wrong weight class for most small businesses, and both expect volume commitments. The one thing I'd push you on: the headline rate matters less than your monthly volume and your average ticket. Under ~$10K/month, take the flat-rate convenience (Square or Stripe) and don't overthink it. Above that, run your real numbers against interchange-plus - that's where switching pays for the hassle. Also check settlement timing; two-day versus same-day deposits hits cash flow harder than a 0.2% rate difference for most small operators.
