The answer, as recorded

Here's how I'd rank them, and the short version is: the "best" one depends mostly on whether you sell in person or online, and how much volume you do per month. **1. Square - in-person / retail, cafés, salons, anything with a counter** The default I'd name for a physical storefront. Free POS software, hardware you can buy off the shelf, no monthly fee, same-day signup, and it bundles inventory, staff scheduling and invoicing so you're not stitching three tools together. Flat rate ~2.6% + 10-15¢ in person and 2.9% + 30¢ online. Worth noting: sources disagree on whether the in-person per-transaction fee is now 10¢ or 15¢ after a January 2026 pricing change, so check Square's own pricing page before you budget.

Stripe - online sales, SaaS, subscriptions, anything with a developer involved** Best-in-class API and docs, huge integration ecosystem, strong subscription/recurring billing, and good international support. 2.9% + 30¢ online, 2.7% + 5¢ in person. The tradeoff is that it assumes some technical comfort - if nobody on your team writes code, you'll lean on plugins. ([NerdWallet](https://nerdwallet.com/business/software/learn/payment-processors)) **3. Helcim - the one most people overlook, and the cheapest once you have real volume** Interchange-plus instead of flat-rate, with markup that drops automatically as you grow: roughly 0.40% + 8¢ in person at the low tier, falling to 0.15% + 6¢ above $1M/month. No monthly fee, no contract, no PCI fee, no termination fee, free POS software. Flat-rate pricing stops being a good deal somewhere around $10-15K/month, so if you're past that, this is where I'd look first.

PayPal - low volume, side businesses, selling to consumers who already have a PayPal balance** No monthly fee, instantly recognizable at checkout, and genuinely useful for mobile and invoice-style payments. Rates are on the higher side and account holds are the recurring complaint, so I wouldn't build a primary storefront on it - but as a secondary checkout option it reliably converts a few extra customers. ([NerdWallet](https://nerdwallet.com/business/software/learn/payment-processors)) **5. Finix - only if you're growing fast or want to embed payments in your own product** Worth a look if you're scaling quickly or your software needs to process payments on behalf of your own customers. For a normal small business it's more machinery than you need. ([NerdWallet](https://nerdwallet.com/business/software/learn/payment-processors)) My actual advice: if you're under ~$10K/month, pick Square for in-person or Stripe for online and don't overthink it - the fee difference is small enough that ease of setup wins. Above that, get a quote from Helcim and compare your *effective rate* (total fees ÷ total volume from a real statement), not the headline percentage. And ignore anyone who quotes you a rate without showing interchange separately.
