Good morning, Nat,
Don't mean to sound argumentative, but if we're talking about Visa/MC, we ARE talking about qual/mid/non.
That's the way it works.
In your case, 2.39% IS your mid-qual rate. Since you are a non-swipe merchant, they are callling it your 'qualified' since they understand none of your transactions will fall into a 'true' qualified bucket because none will be card-in-hand swiped. That's commendable--at least they're being straight with you. I might add 2.39% non-swiped is a pretty decent rate. The lowest mid I've ever soon is around 2.09%, which translates to $2. out of your pocket for every $1000 you process. So unless you're processing mega-bucks, (say $25,000 per month or more VMC) you've probably got pretty fair numbers there.
I still take issue with your statement that 90% of your sales fall into this qualified 2.39% bucket. That would be very very unusual in today's market, since that would mean you almost NEVER get paid with a V or MC classified as a corporate card, foreign card, B to B card or several others, all of which would fall into the higher non-qualified rate bracket. That's almost impossible to do these days. And that non-qualified rate would be much closer to the Amex rate you are quoting (which @ 3.85 also sounds about right).
More likely, you ARE having a bunch of your sales fall into non-qual, but you just don't see it on your statement. Very undersandable, most statements by design are very difficult to make heads or tales out of.
I suggest you do the following. Look at your statement carefully. Take the bottom line fee amount you were charged that month (this is probably the sum of TWO separate numbers on your statement--the discount deducted from each daily batch, and the overage amount debited from your business account at the end of the statement period). Then, divide that number by the total V/MC volume you did that month.
By this means, you arrive at the true discount percentage you actually paid, which you'll find is probably in excess of the 2.39% you expected. If you'd like a little help in this regard, let me know and I'll help you out.
Incidentally, here's another thing to look for on your monthly merchant statement: I'm positive you're getting some (probably a lot) of business on signature debit (aka check cards) cards. Are you being charged the same 2.39% or more on those too? If so, you're being overcharged. Signature debit discount rates should be less than the 2.39% you're charged for credit cards since interchange cost to the processor is much less for these cards (remember the big Walmart lawsuit w/V/MC a few years back??--this is what it was all about). If the processor isn't giving you back the difference and is keeping it for themselves......tht's not fair. If that's the case, you might want to question your processor on this since you're being overcharged a tad.
Have a great weekend.
