Stripe and Helcim represent two of the most popular modern payment processors, but with opposite pricing philosophies. Stripe's flat-rate pricing is predictable and simple. Helcim's interchange+ pricing is cheaper but more complex. Neither charges monthly fees, so the comparison comes down to per-transaction costs and feature needs.
Fee Comparison
Stripe charges a flat 2.9% + $0.30 per online transaction regardless of card type or volume. Helcim charges interchange + 0.50% + $0.25, which averages roughly 2.3% + $0.25 for typical US credit card transactions. On a $100 online payment, Stripe takes $3.20 and Helcim takes approximately $2.55. That's $0.65 savings per transaction — or about 20% cheaper.
Volume Discounts
Helcim offers automatic volume discounts that reduce its markup as your processing volume increases. At higher volumes, Helcim's total effective rate can drop well below 2%. Stripe's rate stays fixed at 2.9% + $0.30 regardless of volume (though very large businesses can negotiate custom rates with Stripe's sales team).
Developer Tools and API
Stripe's API is industry-leading — clean REST design, excellent documentation, extensive SDKs, and a powerful testing environment. Stripe also offers an ecosystem of products: Billing for subscriptions, Connect for marketplaces, Atlas for incorporation, Tax for sales tax, and more. Helcim's API is functional but far less mature. For SaaS businesses, marketplaces, or complex billing scenarios, Stripe's platform capabilities are unmatched.
Free Business Tools
Helcim offers several free tools that Stripe either doesn't provide or charges extra for: a free online store builder, hosted payment pages, invoicing, and a POS app. These free tools make Helcim attractive for small businesses that want to accept payments without building a custom integration. Stripe requires more development work to achieve similar functionality.
Choose Helcim if cost savings are your priority and your integration needs are straightforward. Choose Stripe if you need advanced developer tools, complex billing, or marketplace payment splitting.
