It depends entirely on the agreement you sign with the payment service. I volunteer with a non-profit summer camp -- our kind of organization really only takes payments during half the year, and low-volume ones at that. Therefore when I signed us on with a Visa/MC merchant, our fees were a little different (higher) than your typical store. Interac was offered as an option but the cost (monthly as well as per transaction) was much higher -- and certainly more than 6 cents. In any case Interac was wholly impractical for us since we take the majority of our "orders" (camp applications) through the mail, fax, or online.brunes wrote: ↑The typical merchant fee for an Interac transaction is 5 or 6 cents. It is a flat fee and not percentage based. There is also a small monthly fee to rent the terminals, but amortized over a month's transactions it is not substantial for any moderately active business.
So if a company is charging 25 cents or 40 cents for a fee, they are taking a profit off of it.
I did some quick Googling and 8 or 9 cents was what I found typically (as well as CC rates of about 1.75%). Take into account the monthly terminal fee and I can see why a 25-cent charge might make sense.
