Helcim is a Calgary-based payment processing company that offers genuinely transparent interchange-plus pricing with no monthly fees, no hidden charges, and a comprehensive suite of free payment tools.
Stripe is a leading payment processor known for its developer-friendly API, transparent pricing, and comprehensive suite of payment solutions for businesses of all sizes.
This is the clearest interchange-plus versus flat-rate comparison on the market, because both companies publish their numbers in full. Helcim passes interchange through at cost and adds a stated margin that falls automatically as volume rises; Stripe charges the same 2.9% + 30¢ online whether you process $500 a month or $500,000. Helcim also refunds its chargeback fee when you win, funds you the next business morning for free, and includes invoicing and a storefront. Stripe is a developer platform first: a full API, cheaper hardware and 24/7 support on every account.
Helcim is for an established small or mid-sized business that takes real card volume — in a shop, over the phone, or by invoice — and wants transparent interchange-plus pricing with the business software included and no per-month cost.
Stripe is for software: platforms, marketplaces, subscription products and any team that needs to embed payments in their own product with an API, and will pay a flat rate for the privilege of never talking to an account manager.
These two are not really competing for the same merchant, and the tables show why. Helcim wins everything about being a merchant account: interchange-plus pricing that gets cheaper as you grow, a chargeback fee that comes back when you win, next-business-morning funding at no cost, and invoicing, a virtual terminal and a storefront thrown in. Stripe wins everything about being infrastructure: a $59 reader, 24/7 support on every account, and an API surface Helcim does not attempt to match. For a shop, a clinic, a trades business or anyone invoicing real volume, Helcim is normally the cheaper and better-supported account, and the gap widens with volume because Stripe's rate never moves. For a platform, a marketplace, a subscription product or anything where payments are a feature of your own software, Stripe is the only one of the two that can do the job, and its flat rate is the price of that. The one caution on Helcim's side is that an interchange-plus total cannot be quoted in advance: what you pay depends on which cards your customers present.
| Feature | Helcim | Stripe |
|---|---|---|
| How you are priced | Interchange-plus: card network cost passed through, published margin on top | Flat rate: one blended price regardless of the card or the volume |
| Interchange-plus is normally cheaper once volume or average ticket rises, and it is the model that lets a rewards card cost more than a debit card. A flat rate is easier to forecast and never surprises you. | ||
| In-person margin or rate | Interchange + 0.40% + 8¢ (first $50K/month) | 2.7% + 5¢ flat |
| Helcim publishes a tiered table and the margin steps down automatically as monthly volume rises. The total a Helcim merchant pays depends on the interchange each card carries, so it cannot be stated as a single number. | ||
| Online and keyed margin or rate | Interchange + 0.50% + 25¢ (first $50K/month) | 2.9% + 30¢ flat |
| Stripe adds 1.5% for international cards and a further 1% when currency conversion is required. | ||
| ACH and bank payments | 0.5% + 25¢, capped at $6 | 0.8%, capped at $5 |
| Helcim is cheaper on typical bank payments — a $500 transfer costs $2.75 against Stripe's $4.00. Stripe's lower cap makes it cheaper above roughly $950 per transaction. Helcim adds 0.05% on amounts over $25,000. | ||
Recommendations based on your business type

Interchange plus 0.40% + 8¢ in person almost always lands below Stripe's flat 2.7% + 5¢ at that volume, and Helcim's margin drops further as you grow while Stripe's rate does not move.
Stripe Connect, the API and the SDK coverage are the product here. Helcim has no equivalent for onboarding and paying out to sub-merchants.

Helcim bundles all three at no monthly cost. The nearest Stripe equivalents are Payment Links and Checkout for the storefront, with Billing priced separately from 0.7% of billing volume.

Both charge $15 per chargeback, but Helcim refunds it when you win and Stripe does not return the dispute received fee at all. On a merchant fighting and winning disputes regularly, that difference compounds.
Stripe's documentation, test mode and language SDKs are the reason most teams pick it, and 24/7 support on every account backs that up. Helcim's integration list is aimed at off-the-shelf software, not at code you write yourself.
