The question asked, verbatim: best payment processing for small businesses

Brands named, in the order the engine gave

1. Square recommended
   Square - the default for in-person/retail.
2. Stripe recommended
   Stripe - the default for online/software.
3. Helcim recommended
   Helcim - the one to switch to once you're doing real volume.
4. PayPal recommended
   PayPal - for low volume and invoicing.
5. Shopify recommended
   Shopify Payments - only if you're already on Shopify.
6. Shopify Payments recommended
   Shopify Payments - only if you're already on Shopify.
7. multi-year mentioned
   The one thing I'd avoid is signing a multi-year merchant-account contract with an ETF - all five above are month-to-month, so switching later is cheap.

The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd suggest looking at them: **1. Square - the default for in-person/retail.** Free POS software, a free or cheap reader, no monthly fee, and you can be taking cards the same week. 2.6% + $0.15 in person, 2.9% + $0.30 online. Paid tiers (Plus/Premium) drop in-person to 2.5%/2.4%. Best pick if you have a counter, a food truck, a salon, a market stall. ([Square fees](https://squareup.com/payments/our-fees), [NerdWallet](https://www.nerdwallet.com/business/software/learn/square-fees)) **2. Stripe - the default for online/software.** 2.9% + $0.30 online, 2.7% + $0.05 in person. Best APIs and integrations in the business, great for subscriptions, marketplaces, SaaS, or anything with a custom checkout. Overkill if you just want to swipe cards and go.

Helcim - the one to switch to once you're doing real volume.** Interchange-plus pricing (roughly interchange + 0.15% + $0.15) with automatic volume discounts instead of a flat rate. Flat-rate processors get expensive past about $10-15K/month, and this is where Helcim starts clearly beating Square and Stripe on cost. No monthly fee, no contract. ([Fit Small Business](https://fitsmallbusiness.com/helcim-vs-square/), [Helcim vs Stripe](https://fitsmallbusiness.com/helcim-vs-stripe/)) **4. PayPal - for low volume and invoicing.** Not the cheapest, but no monthly fee, instant customer trust, and good for sending invoices or occasional payments. Fine as a secondary option alongside one of the above rather than your main rail. ([NerdWallet](https://nerdwallet.com/business/software/learn/payment-processors)) **5. Shopify Payments - only if you're already on Shopify.** Bundled rates and zero integration work; the catch is Shopify charges you extra per transaction if you use a third-party gateway instead. ([TechRadar](https://www.techradar.com/best/best-credit-card-processing-service)) The short version: **Square if you sell in person, Stripe if you sell online, Helcim once you're over ~$15K/month.** The one thing I'd avoid is signing a multi-year merchant-account contract with an ETF - all five above are month-to-month, so switching later is cheap.
