## The answer, as recorded

Asked on 2026-09-24 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's how I'd actually rank them, assuming a typical US small business:
> 
> **1. Square - the default if you're under ~$10K/month.** No monthly fee, free reader, flat 2.6% + 10¢ in person, and the POS/invoicing/online ecosystem is all included. It's the lowest-risk choice because there's nothing to negotiate and nothing to cancel. Most small businesses should just start here.
> 
> **2. Helcim - the best value once you're doing real volume ($10K-$50K/month).** Interchange-plus pricing with no monthly fee and automatic volume discounts, averaging around 1.93% + 8¢ in person and 2.49% + 25¢ online. Because it passes through true interchange plus a small markup, it beats flat-rate once your volume is meaningful - one comparison put the savings at ~$3,700/year at $20K/month versus PayPal.
> 
> **3. Stripe - if you're online-first or have a developer.** Best-in-class API, subscriptions, and international/multi-currency support. Overkill if you're just swiping cards in a shop, and its in-person hardware story is weaker than Square's.
> 
> **4. PayPal / PayPal Zettle - cheapest in-person headline rate, and good as a secondary option.** 2.29% + 9¢ in person is genuinely low, and buyer familiarity convert
