Adyen doesn't do flat rates. It runs Interchange++: the card networks' interchange and scheme fees pass straight through, and Adyen adds its own processing fee on top of each transaction. That's the cheapest possible structure for high-volume merchants — and a trapdoor for small ones, because Adyen's economics assume scale. The Canadian pricing that exists on the public record is unusually transparent about wholesale costs and unusually quiet about who gets onboarded.
The Canada fee-disclosure box, decoded
Adyen's Canadian legal page carries a fee-disclosure box — required transparency most processors bury. Each figure is the sum of interchange + network assessment + Adyen's per-transaction processing fee, illustrated on a CA$100 transaction. It is illustrative, not a quote (your agreement may set custom or tiered pricing), but it shows the shape of the cost:
| Card type (Canada) | Card/device present | Not present |
|---|---|---|
| Visa Consumer Credit | 1.52% | 1.44% |
| Visa Infinite | 1.71% | 1.71% |
Compare those numbers to any Canadian flat rate — Square's 2.5% in-person, Stripe's 2.9% + 30¢ online — and the Interchange++ advantage is visible on every line. The catch is everything around the percentage.
Monthly minimums and eligibility: the small-merchant question
Here's what no Adyen page states plainly for Canada: Adyen has historically enforced monthly minimums — reported as $120 or 1,000 transactions per month — and its sales motion targets enterprises, not corner stores. That minimum figure comes from a dated third-party review and is US-context; treat it as a signal of the model, not a current Canadian number, and confirm in writing before applying. The evidence for the enterprise tilt is stronger: on G2, Adyen's largest reviewer segment is Enterprise, its rating sits at 4.0/5 across just 44 reviews, and reviewers praise smart routing and chargeback tooling built for payments teams — not simplicity for a solo founder. If you process under roughly $50,000/month, expect Adyen to be either unavailable or uneconomical; the platform is priced for businesses with a payments function, not a payments problem.
Worked math: $100,000/month, domestic online
The setup: $100,000/month in domestic online card sales, 2,000 transactions ($50 average ticket).
Adyen (illustrative): using the disclosure box's 1.44% all-in illustration for consumer credit not-present: $100,000 × 1.44% ≈ $1,440, plus per-transaction processing fees (reported at $0.12/transaction in US-context reviews — unverified for Canada: ~$240). Illustrative total: ~$1,680/month before any monthly minimum.
Stripe flat: $100,000 × 2.9% = $2,900, plus 2,000 × $0.30 = $600. Total: $3,500/month.
The gap: roughly $1,800/month in Adyen's favour at this volume — if your agreement's processing fee matches the illustration and your card mix is mostly standard domestic. Premium-card-heavy mixes narrow it; the illustration is not a quote.
Payment-method fees in Canada: BNPL isn't cheap
Adyen publishes per-method Canadian pricing, and the buy-now-pay-later numbers deserve attention before you enable them: Affirm's Standard tier runs $0.13 + 4.49% + C$0.30 per transaction in Canada (Core 4.19%, Signature 5.19%), and Afterpay runs $0.13 + 4.99% + $0.30. Affirm absorbs the underwriting and fraud risk and pays you upfront — but at roughly triple the card rate, BNPL is a conversion tool, not a cost saver. Enable it for the lift in average order value, and measure whether the lift covers ~5%.
What merchants say
Reviews split by reviewer type, which tells you the real story. Aggregator ratings are mixed: BBB A, Trustpilot 1.6/5, G2 4/5. Negative themes repeat — poor customer service, a challenging setup process, and fee surprises. Positive reviews cluster around the enterprise features: month-to-month terms with no termination fees, the international footprint, and helpful support staff once you're in. Two named G2 reviews from 2025–2026 capture it: a fraud-risk lead (3.5/5) praised the disputes portal and competitive chargeback fees but found chargeback statuses confusing and support slow; a quality engineer (5/5) praised improved transaction rates and smart routing while calling the dashboard analytics weak. This is a platform its users respect and its onboarding filters hard.
Decision framework
- Under ~$50,000/month: Adyen is probably not your processor — the minimums and the integration overhead point you at Stripe or Square.
- Cross-border or multi-currency: this is Adyen's home turf — one platform, 150+ currencies, local acquiring in many markets.
- Get the processing fee in writing. The disclosure box illustrates wholesale + processing; your agreement sets the actual per-transaction fee. That's the number to negotiate.
- Price BNPL separately. Affirm/Afterpay at ~5% belong in your conversion budget, not your processing budget.
- Termination is clean: either party can end the agreement on two months' written notice — no long lock-in to fear.
A note on steps: this is a pricing explainer, not a setup procedure — the framework above is the actionable part.
FAQ
What does Adyen charge per transaction in Canada?
Interchange + scheme fees passed through, plus Adyen's per-transaction processing fee set in your agreement. Adyen's Canadian disclosure box illustrates the all-in cost on a CA$100 sale: 1.52% card-present / 1.44% not-present for Visa consumer credit. That is illustrative, not a quote.
Is Adyen good for small businesses?
Generally no. The platform targets enterprises — monthly minimums have been reported, the largest G2 reviewer segment is Enterprise, and reviewers note the fee structure punishes low volume. Small merchants usually do better on flat-rate platforms.
Does Adyen charge setup or termination fees?
No setup fees are reported, and the agreement is terminable by either party on two months' written notice — no long-term lock-in.
