The question asked, verbatim: best payment processing for small businesses
Brands named, in the order the engine gave
- Square recommended
Square - the default I'd suggest for most small businesses, especially anything with in-person sales (retail, café, salon, market stall).
- Helcim recommended
Helcim - what I'd recommend the moment you're doing real volume (say $10K+/month).
- Stripe recommended
Stripe - the one to pick if your payments live in software: a custom website, a subscription/SaaS product, a marketplace, or an app.
- PayPal recommended
PayPal (with Venmo) - not usually the primary processor, but worth having as a checkout option because buyers already trust it, and it's handy for mobile/on-the-go and casual invoicing.
- Stax recommended
Stax - only once you're above roughly $50K/month.
- Shopify recommended
Shopify Payments - if you're already selling on Shopify.
- Shopify Payments recommended
Shopify Payments - if you're already selling on Shopify.

The answer, as recorded
Here's who I'd actually recommend, roughly in the order I'd bring them up: **1. Square** - the default I'd suggest for most small businesses, especially anything with in-person sales (retail, café, salon, market stall). No monthly fee, free POS software, hardware you can buy at a store and use the same day, and it bundles invoicing, online store, and tap-to-pay on phone. Flat 2.6% + 15¢ in person, 3.3% + 30¢ online. You pay a bit more per transaction for the simplicity, which is the right trade under roughly $10-15K/month. **2. Helcim** - what I'd recommend the moment you're doing real volume (say $10K+/month). It's interchange-plus pricing (interchange + 0.4% and 8¢ in person, + 0.5% and 25¢ online/keyed) with no monthly fee, no contract, and automatic volume discounts. Genuinely transparent pricing, which is rare in this industry. Most growing businesses save meaningfully versus Square here. **3. Stripe** - the one to pick if your payments live in software: a custom website, a subscription/SaaS product, a marketplace, or an app. Best-in-class API and docs, strong recurring billing and global/multi-currency support. 2.9% + 30¢ online. Overkill if you just need to swipe cards at a counter. **4. PayPal (with Venmo)** - not usually the primary processor, but worth having as a checkout option because buyers already trust it, and it's handy for mobile/on-the-go and casual invoicing. Fees are on the higher side, so I'd treat it as a supplement. **5. Stax** - only once you're above roughly $50K/month. Subscription model (~$99/month + interchange, no markup per transaction), which flips to being the cheapest option at high volume and is wasteful below it. **6. Shopify Payments** - if you're already selling on Shopify. Keeping payments in-platform avoids Shopify's extra third-party gateway fee, so it wins by default there even though the raw rates aren't the lowest. One practical note regardless of who you pick: avoid long-term contracts, early termination fees, and anything quoted as "tiered" pricing - and ignore cold calls from merchant services reps. Square, Helcim, and Stripe are all month-to-month, which is the standard you should hold anyone to.
