For Canadian restaurant and café owners, accepting card payments is no longer a question of whether you should do it. The real question is which payment methods should you prioritize, what will each transaction cost, and how should you structure your payment setup to protect your margins?
Interac Debit and credit cards both have an important place in Canadian restaurants. They serve customers differently, have different processing economics, and can affect everything from average transaction size to cash flow.
For a restaurant owner operating on tight margins, those differences matter.
A café processing hundreds of small transactions every day may look at payment fees very differently from a full-service restaurant processing larger dinner bills. A quick-service restaurant may prioritize fast Interac contactless payments, while a higher-end restaurant may see customers frequently choosing premium credit cards.
The best strategy is usually not to choose between Interac and credit cards. It is to accept both while understanding the economics behind each and negotiating a payment processing arrangement that makes sense for your business.
Interac Debit vs Credit Cards: What Is the Difference?
Interac Debit allows customers to pay directly from their bank account. In a traditional in-person transaction, the customer taps or inserts a debit card and authorizes the payment using their PIN when required.
Credit cards work differently. The transaction is authorized against the customer’s available credit, with the card issuer ultimately billing the customer.
For the restaurant, however, the most important distinction is the way these transactions are generally priced.
Interac Debit is commonly priced using a flat transaction fee, while credit card processing is typically based on a percentage of the transaction, sometimes combined with fixed transaction or other processing fees.
That distinction becomes particularly important for restaurants because restaurant transactions vary considerably in size.
A $7 coffee purchase and a $150 dinner are very different transactions from a payment-processing perspective.
Interac itself describes its debit offering as having low, often flat, transaction fees, while noting that the actual merchant cost depends on the acquirer and payment services provider.
Why Interac Debit Is Important for Canadian Restaurants
Interac is deeply established in Canada. Interac reports that 98% of Canadians have a debit card, which makes Interac Debit a payment method that most restaurant customers already understand.
For restaurant owners, the biggest attraction is often cost predictability.
Suppose a restaurant negotiated an Interac Debit processing cost of $0.10 per transaction. A $20 sale would incur the same $0.10 transaction charge as a $50 sale under that simplified example.
A percentage-based credit card rate behaves differently.
If the restaurant paid 2% on a $20 purchase, the processing cost would be $0.40. At $50, it would be $1.00.
Actual rates vary by processor, card type, transaction type and merchant agreement, so restaurant owners should never assume that one advertised rate represents their actual cost. Canada’s payment-card rules require greater transparency around merchant fees and statements, including information about rates, transaction volumes and applicable fees.
The Pros of Interac Debit
Lower and more predictable transaction costs
For many restaurants, this is the biggest advantage.
A flat debit fee can be particularly attractive for businesses with small average tickets. Cafés, bakeries, quick-service restaurants, food trucks and takeout businesses can process a large number of small purchases without paying a percentage of every sale.
Faster cash flow
Interac Debit transactions can provide quick access to funds and do not have the same chargeback exposure associated with credit card transactions. Interac specifically promotes fast cash flow and zero chargebacks as advantages for merchants.
For a restaurant owner managing payroll, food purchases, rent and other recurring expenses, predictable access to sales revenue has practical value.
Familiar to Canadian customers
Customers generally do not need to learn anything new. Tap, insert, enter a PIN when required, and the transaction is complete.
Useful for smaller purchases
Interac can make particularly good economic sense for low-ticket transactions when the merchant’s debit fee is a reasonable flat amount.
The Cons of Interac Debit
The biggest limitation is that debit does not provide customers with the rewards, points, insurance benefits or credit-building characteristics associated with many credit cards.
Some customers actively want to earn travel points, cash back or other rewards. If a restaurant accepts only debit, it can potentially frustrate those customers.
There is also a practical consideration: Interac Debit does not replace the need for credit card acceptance in a modern Canadian restaurant.
A restaurant that refuses credit cards may save some processing costs, but it could also lose sales or create unnecessary friction at checkout.
Why Restaurants Should Accept Credit Cards
Credit cards are expensive compared with many debit arrangements, but they provide something important: customer choice.
Credit cards are widely used for restaurant purchases, particularly among customers who want rewards, cash back, travel points or the convenience of putting expenses on a credit account.
Credit card acceptance can also become more important as the average transaction increases.
Consider a $100 restaurant bill. If a merchant’s effective credit-card cost were 2%, the processing cost would be approximately $2.00.
That is meaningful.
But the restaurant should compare that $2.00 against the potential revenue lost if customers cannot pay the way they prefer.
For most restaurants, credit card acceptance is therefore less about finding the cheapest individual payment method and more about maximizing sales while controlling payment costs.
The Pros of Credit Cards
Customers expect them
A restaurant that accepts major credit cards removes a significant barrier at checkout.
Credit cards can increase payment flexibility
Customers may have a $100 or $200 restaurant bill but prefer not to use the cash sitting in their bank account.
Credit cards can make larger purchases more comfortable from a budgeting perspective.
Rewards encourage usage
Customers earning points or cash back have an incentive to use their credit cards.
That means restaurants benefit from accepting a payment method that customers may actively prefer.
Better suited to larger transactions
Although the processing percentage is important, customers making larger purchases may be especially likely to expect credit card acceptance.
This is particularly relevant to full-service restaurants, catering operations, private dining and higher-end establishments.
The Cons of Credit Cards
Higher processing costs
This is the obvious drawback.
Credit card processing commonly includes interchange, network assessment and processor or acquirer charges. Depending on the card and agreement, the effective merchant cost can vary considerably.
Premium cards can be particularly important to examine because the cost of accepting different card types may not be identical.
Chargeback risk
Credit card transactions can involve disputes and chargebacks. A restaurant needs to retain appropriate transaction records and follow its processor’s procedures.
Fees can be difficult to understand
A restaurant owner may be quoted a single percentage rate, but the actual merchant statement can contain multiple components.
Canada’s updated payment-card rules are designed to improve transparency, including disclosure of applicable rates and fees.
This is why restaurant owners should evaluate the effective rate, rather than simply choosing the processor advertising the lowest headline percentage.
Interac vs Credit Card Processing Fees
This is where restaurant owners should spend more time.
There is no single Interac or credit card processing rate that applies to every Canadian restaurant.
Your actual cost can depend on:
- Payment processor
- Acquirer
- POS system
- Card network
- Card type
- Debit versus credit
- Contactless versus other transaction methods
- Card-present versus card-not-present transactions
- Monthly transaction volume
- Average transaction size
- Contract terms
- Additional monthly or equipment fees
Interac’s own published fee information illustrates why the merchant’s final price cannot simply be inferred from the network’s underlying fees. Interac publishes wholesale network fees, while merchants separately pay their acquirer or payment processor according to their commercial agreement.
For example, Interac currently publishes a $0.013985 switch fee for eligible Interac Debit chip-and-PIN, card-contactless and mobile-contactless transactions, with a scheduled increase to $0.014438 effective November 1, 2026. That is not the same thing as the total amount a restaurant pays its payment processor.
That distinction is important.
Restaurant owners should not compare a network fee with a processor’s merchant rate as though they are equivalent.
A Simple Restaurant Payment Cost Example
Imagine a café processes 10,000 card transactions per month with an average transaction of $15.
Total monthly card sales would be:
10,000 × $15 = $150,000
Now suppose, purely for illustration, that the café pays:
- $0.10 per Interac transaction
- 2% effective cost for credit card transactions
If 70% of customers use Interac and 30% use credit:
Interac
7,000 transactions × $0.10 = $700
Credit cards
3,000 transactions × $15 = $45,000 in credit card sales
At 2%, processing would equal:
$900
Total illustrative processing cost:
$1,600 per month
Now imagine the same restaurant has a $30 average ticket instead.
The number of transactions remains 10,000, but sales rise to $300,000.
The Interac cost would remain $700 under the simplified flat-fee assumption, while credit card processing would rise substantially.
This is why average transaction size is one of the most important numbers when evaluating payment processing.
A flat debit fee becomes relatively more attractive as the transaction gets larger.
Should Restaurants Encourage Customers to Use Interac?
Yes, but be careful about how you do it.
If your payment agreement makes Interac significantly cheaper than credit cards, encouraging debit can improve your payment economics.
You could use simple messaging such as:
“Prefer debit? We accept Interac.”
You can also train staff to avoid automatically steering every customer toward a particular payment method.
The better approach is to make payment options visible and easy.
Interac itself promotes merchant signage designed to encourage customers to choose Interac Debit.
However, restaurants should not build their entire payment strategy around forcing customers toward debit.
A customer who wants to pay with a credit card should be able to do so.
What About Credit Card Surcharges?
Canadian merchants can generally add a surcharge to eligible credit card transactions, subject to applicable rules and network requirements. Quebec is an important exception.
The Financial Consumer Agency of Canada states that merchants may add a credit card surcharge, subject to requirements including advance notice, disclosure and a maximum surcharge of 2.4%. The surcharge also cannot exceed the merchant’s actual cost of accepting the credit card.
This makes surcharging a potentially useful tool, but it should not be treated casually.
If you introduce a surcharge, your POS system, receipts, menus, signage and customer-facing checkout experience need to be configured correctly.
You should also confirm the rules with your payment processor before implementing one.
For many restaurants, simply building payment costs into menu pricing is easier operationally than creating a separate surcharge.
What Should a Canadian Restaurant Prioritize?
For most restaurants, the answer is straightforward:
Accept both Interac Debit and credit cards.
The objective is not to eliminate the more expensive payment method. The objective is to control the cost of accepting every payment method your customers expect to use.
A sensible priority looks like this:
1. Make Interac Debit easy to use
For Canadian restaurants, Interac should be a core payment option.
It is familiar, fast and potentially economical, particularly for lower-ticket purchases.
2. Accept major credit cards
Do not sacrifice customer convenience simply to reduce processing expenses.
Credit card acceptance can be important for customer acquisition, larger transactions and repeat business.
3. Negotiate your processor agreement
Do not accept the first payment processing proposal you receive.
Ask for a detailed breakdown of:
- Interac transaction fees
- Visa rates
- Mastercard rates
- Premium card rates
- American Express rates, if accepted
- Per-transaction charges
- Monthly fees
- Terminal fees
- POS integration fees
- Chargeback fees
- Refund fees
- PCI-related fees
- Cancellation fees
- Contract terms
The Canadian Code of Conduct provides merchants with protections around fee disclosure and requires clearer information about applicable payment-card costs.
4. Measure your effective processing rate
Do not judge your processor based solely on its advertised rate.
Calculate:
Total payment processing costs ÷ total card sales = effective processing rate
Do this every month.
Your POS and accounting data should make this relatively straightforward.
5. Look at payment mix
Track what percentage of transactions are:
- Interac Debit
- Visa
- Mastercard
- American Express
- Other accepted payment methods
Then compare that mix against your average transaction value.
This gives you a much better picture of your actual payment economics.
What About Cafés and Quick-Service Restaurants?
Cafés should pay particular attention to Interac because their average transaction values can be relatively small.
Imagine a customer buying a $6 coffee.
A percentage-based fee may seem insignificant in isolation, but multiplied across thousands of transactions, it becomes a real operating expense.
Quick-service restaurants, bakeries and food trucks have a similar consideration.
For these businesses, a payment strategy that keeps low-ticket transactions economical can have a noticeable impact on margins.
A full-service restaurant with a $70 or $100 average transaction should still care about debit economics, but credit card acceptance becomes even more important because customers frequently expect credit options for larger bills.
Should You Offer Cash Discounts?
Canadian merchants can offer discounts for different payment methods under the applicable payment-card rules.
However, cash introduces its own operational costs.
Someone has to:
- Count the cash
- Reconcile the till
- Prepare deposits
- Transport deposits
- Manage change
- Investigate discrepancies
- Protect the cash from theft
So do not automatically assume cash is cheaper simply because there is no card-processing percentage.
For many modern restaurants, electronic payments are operationally easier to track and reconcile.
Your POS System Matters
Payment processing should not be viewed separately from your POS.
Your POS should make it easy to see sales by payment method and reconcile those payments with your bank deposits.
A good restaurant POS should help you understand:
- Total sales
- Interac sales
- Credit card sales
- Refunds
- Discounts
- Tips
- Taxes
- Payment processing
- Daily reconciliation
This becomes increasingly important as a restaurant grows.
If you operate three locations, manually comparing payment reports becomes tedious. If you operate ten, it can become a serious accounting and management problem.
The payment system should feed clean data into your broader restaurant management process.
The Biggest Mistake Restaurant Owners Make
The biggest mistake is focusing on the lowest advertised processing rate instead of the lowest total cost.
A processor offering 1.5% may not necessarily be cheaper than one charging 1.8%.
Why?
Because the first provider could have:
- Higher transaction fees
- Monthly minimums
- Equipment charges
- PCI fees
- Statement fees
- Higher rates for certain card types
- More expensive refunds
- Contract termination charges
The right comparison is your all-in effective cost.
Ask each processor to model the cost using your actual restaurant numbers.
For example:
Monthly sales: $150,000
Average transaction: $25
Monthly transactions: 6,000
Interac share: 50%
Credit share: 50%
Then ask each provider to estimate the complete monthly cost.
That is much more useful than comparing two advertised percentages.
The Bottom Line for Canadian Restaurant Owners
Interac Debit and credit cards are not competing payment methods where one must win.
They serve different customer preferences and have different economics.
Interac Debit is particularly attractive because it can offer low, predictable transaction costs, fast access to funds and no credit-card-style chargeback exposure.
Credit cards are important because customers expect flexibility, rewards and the ability to pay larger restaurant bills using credit.
For most Canadian restaurants and cafés, the best strategy is therefore to accept both.
Prioritize Interac for efficient everyday transactions, especially where your average ticket is low, but do not discourage credit card customers simply to save processing fees.
Instead, negotiate aggressively with your processor, understand your effective rate, monitor your payment mix and make sure your POS gives you accurate reporting.
The goal is not to get customers to use the cheapest payment method at all costs.
The goal is to make every sale available to the customer while keeping the cost of collecting that sale under control.
For a restaurant operating on a few percentage points of net profit, that difference can add up to thousands of dollars over a year.
And that is why payment processing deserves the same attention as food costs, labour and rent.
