## The answer, as recorded

Asked on 2026-10-03 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's how I'd rank them, assuming a typical US small business:
> 
> **1. Square** - The default recommendation, especially if you sell in person or across multiple channels. 2.6% + 10¢ card-present, no monthly fee, hardware you can buy incrementally, and POS/invoicing/appointments/payroll all built in. Setup is same-day and you don't need a developer. Best fit under roughly $25K/month in volume.
> 
> **2. Stripe** - The better pick if your business is primarily online, subscription-based, or needs custom checkout logic. 2.9% + 30¢ online, 2.7% + 5¢ in person. Best-in-class APIs and documentation, strong recurring billing and marketplace support. Overkill if you just want to swipe cards at a counter.
> 
> **3. Helcim** - Where I'd send you once you're past about $5-10K/month. It's interchange-plus rather than flat-rate, so you pay actual card-network cost plus a small transparent margin - effective rates average around 1.93% + 8¢ in person and 2.49% + 25¢ online. No monthly fee, no PCI fee, and volume discounts are automatic. Less polished ecosystem than Square, but materially cheaper at scale.
> 
> **4. PayPal (incl. PayPal Checkout/Zettle)** - Worth adding as a *secondary* option rather than you
