Square vs Helcim
Square vs Helcim comparison: flat-rate simplicity vs interchange-plus savings. Compare pricing, features, and which is cheaper at your volume. Find the right payment processor for your business.
Quick Answer
Square is the better choice if you are a small or seasonal business that values simplicity — free POS software, free card reader, and predictable flat-rate pricing for in-person (2.6% + $0.15) and online (3.3% + $0.30) transactions. Helcim is the better choice if you are a mid-to-high-volume business (processing $10,000+/month) that wants the lowest possible processing fees through interchange-plus pricing — Helcim can save 30-50% over Square's flat rates at scale. The trade-off is simplicity: Square is plug-and-play, while Helcim's interchange-plus model requires more attention to monthly statements. Square operates in 5 countries; Helcim in US and Canada only.

Pros
- +Most transparent pricing model in the industry — interchange-plus means your effective rate drops as your volume grows, unlike flat-rate processors where cost increases linearly with volume
- +Significantly cheaper than Stripe, Square, or PayPal for businesses processing $10,000+/month — savings of 30-50% on processing fees are common at scale
- +No contracts or early termination fees — you can leave anytime without penalty, which is rare in the payment processing industry
- +Subscription billing add-on at 0.4% is nearly half Stripe Billing's 0.7%, saving meaningful money for businesses with recurring revenue models
- +No monthly minimums or PCI compliance fees — truly pay-for-what-you-use pricing
Cons
- −US and Canada only — no global reach for businesses selling internationally or with cross-border payment needs
- −Less name recognition than Stripe, Square, or PayPal — may be less familiar to customers and business partners
- −Smaller integration ecosystem — fewer native connections to CRMs, accounting platforms, and e-commerce tools compared to the major processors
- −Interchange-plus pricing requires more attention to monthly statements than flat-rate pricing — not ideal for business owners who prefer simplicity
- −Less suitable for businesses processing under $5,000/month where flat-rate simplicity from Square or PayPal makes more sense than tracking interchange categories
