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.
- Settlement
- Typically next business day, batched with your card settlement
- Cost basis
- 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
- Flat percentage pricing that bills debit as if it were credit, so the rail is never priced as what it is
On a fitted agreement, debit is priced as a flat per-transaction cost. The review shows what yours would be.
Illustrative example. Your fitted rate is negotiated against your actual statement.
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. On a properly structured agreement, a $200 debit sale and a $9 one cost you nearly 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 holds an acceptance profile priced in cents per item, not points of revenue. The only way to lose that structure is an agreement that averages debit into a percentage blend, and an extraordinary number of Canadian businesses hold exactly that agreement.
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 is stark on high count counters: hundreds of daily taps that should cost cents each, quietly billed as percentages of every sale.
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 would any business pay a percentage on debit?
Because flat rate simplicity bundles it that way, and the cost is invisible until someone reads the statement against the network's actual pricing model.
Does debit's flat pricing hold at any transaction size?
Yes: flat per item pricing means the fee stays in cents while the ticket grows. A large debit sale carries the same flat per item cost as a small one.
