Interac debit processing
Interac debit often carries its own flat per item cost profile, and it is the most commonly mispriced rail most Canadian businesses accept. The network charges cents per transaction. Whether you pay cents is a different question, answered by your agreement.

- Flat per transaction fees measured in cents at the network level, and on most agreements not a percentage of the sale
- Best for
- Debit heavy counters: cafes, quick service, grocery, convenience, high frequency retail
- Watch for
- Debit priced very differently from one agreement to the next, and statements that do not break it out as its own line
Debit is usually priced per transaction rather than as a percentage of the sale. The review shows what you pay today and what we can quote in writing.

How it works
Interac Flash handles the tap; chip and PIN handles the insert. Both route through Canada's domestic debit network.
Debit draws directly on the customer's bank account at authorization. No credit risk, no issuer float.
Network pricing is per transaction. Where your agreement prices debit per item, as most do, a $200 debit sale and a $9 one cost about the same.
Canada's home field advantage
Interac is a domestic network with domestic economics: flat, per transaction pricing in cents that reflects debit's low risk. A business whose customers tap debit all day usually carries a cost profile priced per item rather than in points of revenue. What that structure costs you in practice depends on the agreement behind the terminal: the per item fee it sets and whether it breaks debit out as its own line, which is what the review reads.
Reading your debit line
On a well structured statement, debit appears as its own category with per item pricing. If your statement shows debit inside one blended rate, or does not break it out at all, that is the first thing to fix. The arithmetic matters most on high count counters: hundreds of daily taps, where a small difference in the per item fee adds up over a year.
Debit and the modern wallet
Debit tapped through Apple Pay or Google Pay still routes through Interac rails with its economics broadly intact, so embracing mobile wallets does not surrender debit's economics. Contactless transaction limits, commonly around the $250 mark since the pandemic era increases, cover the overwhelming majority of everyday purchases.
Common questions
What does Interac debit actually cost to accept?
At the network level, cents per transaction. Your cost depends on your agreement's markup structure, which is why the same tap can be priced very differently depending on the agreement behind the terminal.
Does debit through Apple Pay cost the same as a card tap?
Mobile wallet debit generally preserves debit economics, with some variation by setup. The review breaks out exactly what your wallet taps cost under your current agreement.
Why does debit cost more on some agreements than others?
Because the per item fee and the way debit is itemized differ by processor and agreement, and processors can change pricing at any time. The review reads your debit line and quotes in writing what we can offer.
Does debit's flat pricing hold at any transaction size?
Usually. Where debit is priced per item, as it is on most agreements, the fee does not grow with the ticket, so a large debit sale costs about the same as a small one. Your agreement sets the terms, and we quote them in writing.
