Adyen and Stripe are the two platforms every scaling company evaluates — and most comparisons get the decision wrong by treating it as a feature contest. It isn't. Adyen prices on Interchange++ (wholesale cost plus a published markup), built for enterprise retail and omnichannel volume. Stripe defaults to blended flat-rate pricing (2.9% + $0.30), built for developer velocity from startup to mid-market. The real question is a number: at what annual volume does Interchange++ pay for itself? This guide works it in Canadian dollars.
Interchange++ vs blended, in one paragraph
Under Adyen's Interchange++, you pay the card networks' exact wholesale cost, plus the scheme fee, plus Adyen's markup — published at USD $0.13 per transaction plus 0.60%, negotiated down at enterprise volume. Under Stripe's blended model, you pay 2.9% + $0.30 whether the underlying card costs 1.2% or 2.4% wholesale — Stripe absorbs the variance and keeps the difference on cheap transactions. One nuance the comparisons bury: Stripe does offer interchange-plus on custom enterprise packages. It is not always blended — but blended is the default, and IC+ is the negotiation.
| Adyen | Stripe | |
|---|---|---|
| Pricing model | Interchange++ (default) | Blended 2.9% + $0.30 (default); IC+ on enterprise deals |
| Published markup | USD $0.13/txn + 0.60% (negotiable) | N/A (blended) |
| Chargeback fee | $5–$100 | $15 |
| Best for | Enterprise, high volume, omnichannel retail | Startups to mid-market, developer teams |
| Integration effort | Weeks to months | Days to weeks |
| G2 rating | 4.0/5 (44 reviews, enterprise segment) | Strong developer ratings |
Worked math: the Canadian volume threshold
The setup: a Canadian retailer doing CAD $18 million/year online (~GBP 10M, the threshold enterprise analyses cite), average ticket $85.
Stripe blended: $18,000,000 × 2.9% = $522,000/year in percentage fees (plus per-transaction fees).
Adyen Interchange++: wholesale on a retail card mix averages ~1.55% ($279,000) + 0.60% markup ($108,000) + ~212,000 transactions × USD $0.13 (~$37,000 CAD). Total: ~$424,000/year — roughly $98,000/year less than blended, before the markup is even negotiated down.
The threshold logic: every 10 basis points of processing cost on $18M/year is $18,000/year. Below ~$5M/year, the reconciliation overhead of Interchange++ invoicing often eats the savings — Stripe's predictability wins. Above ~$15–$20M/year, the math is overwhelmingly Adyen's, and the only real negotiation is whether Stripe's enterprise IC+ package can match it.
The Canadian enterprise gaps neither comparison covers
Every Adyen-vs-Stripe comparison is written for the US or UK. For a Canadian enterprise, two questions go unanswered everywhere: Interac acceptance and CAD settlement with Canadian acquiring. Adyen's local acquiring depends on legal entity and regulatory requirements in each market — confirm Canadian acquiring and Interac support in writing before assuming the global platform covers the domestic checkout. Stripe's Canadian offering is mature on cards but has the same Interac gap as its SMB product. Neither vendor's marketing answers this; your RFP must.
What merchants report
Adyen holds 4.0/5 on G2 (44 reviews), its largest segment enterprise — reviewers describe pricing as fair with no setup fees, but note the structure gets confusing and punishes low-volume merchants. TrustRadius reviewers praise the absence of refund and chargeback processing fees and the attractive processing rates, while flagging confusing chargeback status reporting. Stripe's enterprise reviews praise the API and reliability — with the familiar aggregator shadow: frozen-funds cases and support limits recur even at scale.
Who fits whom
- Choose Adyen if you process over ~$15M/year, run omnichannel (online + in-person), or operate across borders and need local acquiring with one reconciliation.
- Choose Stripe if you are under ~$5M/year, need to ship fast, or live on subscriptions and developer-built flows. Predictability beats 10 basis points at this scale.
- Between $5M and $15M: run both quotes — and ask Stripe for its enterprise IC+ package. The blended default is not the final offer.
- RFP the Canadian gaps. Interac acceptance, CAD settlement, Canadian acquiring entity — get all three in writing from either vendor.
A note from the audit desk: at enterprise scale, contract terms and volume commitments are the silent killers — negotiate the markup, the commitment, and the exit together, never separately.
A note on steps: this is a buying-decision guide, not a repair procedure — the numbered framework above is the actionable part, and there is no settings path to click through.
FAQ
Is Adyen cheaper than Stripe?
Above ~$15M/year in volume, consistently — Interchange++ beats blended by tens of thousands a year. Below ~$5M/year, Stripe's simplicity usually wins on total cost.
Does Stripe offer interchange-plus pricing?
Yes — on custom enterprise packages for large-volume accounts. It is not the default and not advertised, but it exists. Ask for it by name in any enterprise negotiation.
At what volume should a Canadian business switch to Adyen?
The rule of thumb from enterprise analyses is ~$15–$20M CAD/year in card volume. At that scale, even a 10-basis-point improvement is $15,000–$20,000 a year — enough to justify the integration effort.
