The answer, as recorded

Here's how I'd rank them, assuming a US small business: **1. Square - the default if you sell in person.** Free POS software and a cheap/free reader, flat 2.6% + 10¢ in person and 2.9% + 30¢ online, no monthly fee or contract. The whole stack (register, invoices, online store, payroll, loans) is in one account, so a café, salon, or retail shop can be taking cards the same day. It's the most common "best overall" pick in the roundups for exactly this reason.

Stripe - the default if you sell online or build software.** 2.9% + 30¢ online, no monthly fee, and by far the best developer tooling: subscriptions, usage-based billing, marketplaces, hosted checkout, global cards and wallets. If you have a dev or you're running SaaS/a marketplace, this is the one. Downside: support is largely ticket-based and it's overkill for a plain storefront. ([NerdWallet](https://nerdwallet.com/business/software/learn/payment-processors)) **3. Helcim - the one to switch to once you're doing real volume.** Interchange-plus pricing with no monthly fee and no gateway fee, averaging roughly 1.83% + 8¢ in person and 2.27% + 25¢ online, with automatic volume discounts. At maybe $10-15k/month or with high average order values, it genuinely undercuts Square and Stripe. Trade-off is a thinner integration ecosystem. ([TechRepublic](https://www.techrepublic.com/article/stripe-alternatives/), [Jim.com](https://www.jim.com/blog/helcim-vs-square)) **4. PayPal - as a secondary checkout button, not your main processor.** Adding PayPal/Venmo at checkout measurably lifts conversion for consumer sales, and its in-person rate (2.29% + 9¢) is competitive. But 3.49% + 49¢ on PayPal-wallet online transactions is expensive as a primary rail, and it has a long reputation for abrupt account freezes. Use it alongside Stripe or Square. ([FitSmallBusiness](https://fitsmallbusiness.com/stripe-vs-square-vs-paypal)) **5. Shopify Payments - only if you're already on Shopify.** It's Stripe underneath, and Shopify charges you an extra fee if you use any other processor, so the decision is really just "am I on Shopify." **6. Toast or Clover - vertical POS for restaurants and specific trades.** Pricier than Square and tied to their hardware, but Toast's kitchen/table-management features are worth it for a full-service restaurant in a way generic processors aren't. Two practical notes: skip anything with a multi-year contract, early-termination fee, or a leased terminal (that's the classic merchant-services trap), and ignore "free terminal" offers that bundle one. And if a provider pitches surcharging/cash discounting to push fees onto customers, check your state rules and card-network requirements first - it's legal in most of the US but the implementation details matter. Starting point for most people: **Square if you take cards face-to-face, Stripe if you take them online, revisit Helcim once monthly volume is meaningful.** Sources: - [NerdWallet - 5 Best Payment Processors for Small Business](https://nerdwallet.com/business/software/learn/payment-processors) - [FitSmallBusiness - Stripe vs Square vs PayPal](https://fitsmallbusiness.com/stripe-vs-square-vs-paypal) - [TechRepublic - Best Stripe Alternatives and Competitors](https://www.techrepublic.com/article/stripe-alternatives/) - [Jim.com - Helcim vs Square](https://www.jim.com/blog/helcim-vs-square)
