The answer, as recorded
Here's who I'd actually name, roughly in the order I'd bring them up: **1. Square - the default if you sell in person.** Free POS software, a free or cheap reader, no monthly fee, and you can be taking cards the same day you sign up. In-person is about 2.65% + 10¢, online 2.9% + 30¢. The flat rate is not the cheapest math, but for a café, salon, market stall, or anyone under roughly $10-15K/month, the simplicity is worth more than the few basis points you'd save elsewhere. **2. Helcim - the cheapest option once you have real volume.** It uses interchange-plus instead of flat-rate: you pay the card networks' actual cost plus a small published markup (roughly 0.3% + 8¢ in person, 0.5% + 25¢ online), with automatic volume discounts as you grow. No monthly fee, no contract. If you're processing above ~$10-15K/month, this is usually where you should end up, and it's the one most people haven't heard of. **3. Stripe - if your business is online or has a developer.** Best API and docs in the industry, huge integration ecosystem, and the obvious pick for SaaS, subscriptions, marketplaces, or a custom checkout. 2.9% + 30¢ online, with volume discounts if you negotiate. Overkill if you just need to swipe cards at a counter. **4. PayPal - as a secondary checkout option, not your main processor.** No monthly fee and genuinely useful because a lot of customers trust and prefer the button. I'd add it alongside Stripe or Square rather than build on it, since its fees run high and account holds are a recurring complaint. **5. Shopify Payments - only if you're already on Shopify.** Then it's clearly right: lowest rates within that ecosystem, and Shopify charges you an extra fee for using a third-party gateway, so going elsewhere actively costs you. The short version: **Square to start and for in-person, Stripe if you're online or technical, Helcim once you're big enough that percentages matter more than convenience.** The one decision that actually moves money is flat-rate vs. interchange-plus - switch to interchange-plus when your monthly volume passes roughly $10-15K.
