Helcim earns its place among the cheapest credit card processors thanks to its interchange-plus pricing model, which passes through the actual wholesale interchange rate and adds a small, transparent markup of just 0.40% + $0.08 per in-person transaction. Unlike flat-rate processors such as Square (2.6% + $0.10) or SumUp (2.75%), Helcim’s effective rate is often significantly lower, particularly on debit card transactions and for businesses processing mid-to-high volumes.

What makes Helcim especially affordable is the absence of recurring costs that other processors charge. There are no monthly subscription fees, no setup fees, no statement fees and no PCI compliance fees. Businesses only pay when they process a transaction, which is ideal for seasonal operations or startups still building their sales volume. Helcim also processes the first $5,000 in payments for new merchants at no charge, further reducing the barrier to entry.
Helcim’s automatic volume discounts mean that as your monthly processing grows, your per-transaction markup decreases. This creates a pricing structure that rewards growth rather than penalizing it, which is a meaningful differentiator from flat-rate processors where the rate stays the same regardless of volume.
In addition to affordable processing, Helcim includes a full suite of business tools at no extra cost: free POS software for mobile, desktop and the Helcim Smart Terminal; a virtual terminal for keyed-in payments; online invoicing; a hosted e-commerce store; recurring billing; and customer management tools. Competitors often charge monthly subscription fees for similar software features, which can add $15 to $100+ to your monthly expenses.
Helcim’s chargeback fee of $15 is competitive and is refunded if the merchant wins the dispute. Next-business-day deposits are free, whereas many processors charge a fee for expedited funding. ACH processing is available at 0.5% + $0.25 for transactions under $25,000.
The primary cost consideration with Helcim is hardware. The Helcim Card Reader costs $199 and the Smart Terminal costs $349, which is higher than the entry-level hardware offered by Square ($49) or SumUp ($19). However, because Helcim’s ongoing transaction costs are typically lower, businesses that process a meaningful volume of card payments often recoup the hardware difference within a few months of lower fees.
