## The answer, as recorded

Asked on 2026-10-23 through Claude (Anthropic) with web search (model claude-opus-5).

> 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.
