The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd suggest considering them: **1. Square - the default for most small businesses.** $0/month, free card reader, flat 2.6% + 10¢ in person and 2.9% + 30¢ online. You can be taking payments same day, and the ecosystem (invoicing, POS, payroll, ACH) grows with you. If you're under roughly $25-50K/month in card volume and don't want to think about processing, stop here. **2. Stripe - if your business is primarily online or you're building the checkout yourself.** Same 2.9% + 30¢ flat rate, but the best API, docs, and subscription/billing tooling in the business. Overkill if you're a coffee shop; the obvious pick if you're a SaaS or a custom storefront. **3. Helcim - once you're past ~$25-35K/month.** Interchange-plus pricing (interchange + 0.40% + 8¢ in person, + 0.50% + 25¢ online) with no monthly fee and no contract. Effective rates land around 1.93% in person, which meaningfully beats flat-rate Square/Stripe at volume. This is the one most people don't know about and should. **4. PayPal - as a secondary option, not your primary.** Adding PayPal/Venmo as a checkout button lifts conversion for consumer sales, but I wouldn't run your whole business on it - account holds are a real and recurring complaint. **5. Clover - if you need serious countertop POS hardware.** Rates start at 2.3% + 10¢, but it carries a required software subscription from ~$14.95/month and the hardware is often locked to the reseller who sold it to you. Only worth it if you genuinely need the retail/restaurant POS features. **6. Shopify Payments - only if you're already on Shopify.** Integrated rates and you avoid Shopify's extra transaction fee for third-party gateways. Not a reason to switch platforms, but a reason not to bolt on a separate processor. The short version: **start with Square, use Stripe if you're online-first, and switch to Helcim when your volume makes interchange-plus worth the setup.** Also - whatever you pick, avoid anything with a multi-year contract, early termination fee, or leased hardware. The good options in 2026 all have $0 monthly and month-to-month terms, so there's no reason to sign one. One caveat on sourcing: several of the comparison sites below are affiliate-funded, so treat their rankings with some skepticism - the actual published rates I quoted are the part worth relying on, and you can verify those on each provider's own pricing page.
