The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd consider them: **1. Square - the default for most small businesses, especially in-person.** No monthly fee, free POS software, hardware you can add as you need it, and it handles in-person, online, invoices, and ACH out of one account. 2.6% + 10¢ in person, 2.9% + 30¢ online. If you're under roughly $10K/month in volume, this is the lowest-risk choice - the flat rate isn't the cheapest possible, but you're not paying for anything you don't use. **2. Stripe - if you sell online and someone on your team can touch code.** Same 2.9% + 30¢ as Square online, but far better APIs, subscriptions/recurring billing, and international support. It's the standard for SaaS and custom checkout flows. Overkill if you just want a "pay now" button on a Squarespace site. **3. Helcim - the one to switch to once you're past ~$10-25K/month.** Interchange-plus pricing instead of flat rate, so you pay actual card network cost plus a small fixed markup, with volume tiers that drop as you grow. Averages around 1.93% + 8¢ in person and 2.49% + 25¢ online, no monthly fee and no contract. Reports put savings at 20-40% versus Square/Stripe at higher volumes. The tradeoff is less polished software and a real underwriting process. **4. PayPal - as a secondary option, not your primary.** Worth enabling at checkout because a meaningful share of buyers trust it and convert better with it, but its dispute handling and account-freeze reputation make it a poor sole processor. **5. Stax or similar subscription-pricing processors - only above ~$50K/month.** You pay a flat monthly fee plus interchange with near-zero markup. The math only works at serious volume; below that the subscription eats the savings. Two things that matter more than the brand: whether you take payments in person or online (this decides between Square and Stripe more than anything else), and your monthly volume (this decides flat-rate versus interchange-plus). Avoid anyone selling you a multi-year contract with an early termination fee - none of the above require one.
