Ever had a merchant ask why their processing costs change month to month?
The answer almost always comes back to interchange and if you can explain it clearly, you instantly become a more trusted partner.
Here's the short version: interchange is a fee paid to the cardholder's bank every time a transaction happens. Visa and Mastercard set it, processors pass it through, and merchants absorb it. The rate isn't fixed, it shifts based on card type, how the card is used, and even the industry the merchant is in.
Understanding that is the difference between giving a merchant a rate and actually helping them understand their statement.
