Stripe and Moneris are the two default answers to completely different questions. Stripe is the developer's payment platform: world-class APIs, flat-rate pricing, no contract, live in an afternoon. Moneris is Canada's bank-owned acquirer — the RBC/BMO joint venture — with published starting rates, in-person hardware, and Interac support down to the tap. Picking between them is really picking between an online-first platform and a Canadian full-stack acquirer.
What each publishes (dated October 2026)
| Stripe | Moneris | |
|---|---|---|
| Online credit | 2.9% + $0.30 | Interchange + 0.10–0.25% + $0.05–$0.10 |
| In-person credit | 2.7% + $0.05 (Terminal) | From 2.65% + $0.10 (flat-rate) |
| Interac debit | Not supported | $0.03–$0.12 per transaction |
| International cards | 3.2% + $0.30 | Interchange + higher markup |
| Monthly fee / contract | $0 / none | $0–$49.95 / varies, negotiate |
| Chargeback fee | $15 | $25 |
| Hardware | Terminal readers from ~$79 (WisePad 3) | Go Terminal $34.95/month |
One thing worth knowing: comparison sites like Slashdot list "no price information available" for Moneris — but Moneris publishes its flat-rate floor on its own retail page. Always check the vendor's own pricing page before trusting a comparison grid.
The Interac hole in Stripe
This is the line that ends the debate for a large share of Canadian merchants: Stripe does not support Interac debit at all. If your customers tap debit — and in Canadian retail, grocery, and quick-service they overwhelmingly do — every one of those transactions has to go somewhere else, or you are pushing debit customers onto credit rails at credit prices. Moneris prices Interac at $0.03–$0.12 a tap.
The 2026 Canadian gateway comparison lays it out plainly: Stripe's row reads "Not supported" for both in-person and online Interac. For an online-only business this barely matters. For anyone with a counter, it is close to disqualifying on its own.
Worked math: a $15,000/month online-only store
The setup: $15,000/month online, $60 average ticket (250 transactions), domestic cards.
Stripe: $15,000 × 2.9% = $435, plus 250 × $0.30 = $75. Total: ~$510/month (effective rate 3.40% — the per-transaction fee bites at small tickets).
Moneris Simplified (interchange-plus): wholesale on a typical online mix runs ~1.9% ($285) plus markup ~0.20% ($30) plus ~$0.08/transaction ($20). Total: ~$335/month (effective rate ~2.23%).
The gap: roughly $175/month — about $2,100 a year — in Moneris's favour at this volume. But Stripe needs no contract, no negotiation, and no hardware relationship: you are trading roughly $2,100 a year for zero procurement friction and the industry's best developer tooling.
Contracts, chargebacks, and friction
Stripe's contract is simple because there isn't one. Moneris's varies — quote-driven, negotiable, and worth reading line by line. Chargebacks cost $15 on Stripe and $25 on Moneris, and Moneris's payout speed (next business day) beats Stripe's two business days.
Both carry aggregator-style risk stories in reviews, in opposite directions. Stripe's TrustRadius reviews include a CPA firm shut down after ~$8,000 processed with funds clawed back after services were delivered, and an event organizer whose €50,000 was frozen weeks before the event. Moneris's G2 page sits at 3.5/5 (12 reviews) with reviewers citing high fees and opaque pricing — and a September 2026 Trustpilot review from a four-year customer describes discovering rates "much higher than expected" and then being charged a $250 restocking fee on exit. The pattern: Stripe's risk is sudden, Moneris's is slow.
Who fits whom
- Choose Stripe if you are online-first, need developer APIs, subscriptions, or multi-currency, and can live without Interac. The flat rate is the price of zero friction.
- Choose Moneris if you take in-person payments, run debit-heavy, want Canadian bank-tied support, or process enough volume that interchange-plus beats blended by four figures a year.
- Count your debit taps. If Interac is more than a fifth of your transactions, Stripe's missing debit support decides the answer before pricing does.
- Negotiate the markup, audit annually. On Moneris, get the interchange-plus markup in writing and re-check your effective rate yearly — the Trustpilot pattern of slow rate creep is real.
A note from the audit desk: contract length and termination fees are the silent killers in this industry — double-check them before signing, especially the equipment-return and restocking terms that surfaced in Moneris's recent reviews.

FAQ
Does Stripe support Interac debit?
No — not in person and not online. Canadian merchants with meaningful debit volume need a second rail or a different processor.
Is Moneris cheaper than Stripe?
At volume, usually yes on interchange-plus — the worked example shows ~$2,100/year on $15K/month online. At low volume, Stripe's zero-friction, no-contract setup often wins on total cost of ownership.
Why do comparison sites say Moneris has no pricing?
Because Moneris's best pricing is quote-driven. But it does publish flat-rate starting prices (2.65% + $0.10 in person) on its own site — use those as the ceiling in any negotiation, not the floor.
