Non‑qualified surcharges, and why most of your cards land there.

The quoted rate applies to a minority of your sales

Tiered pricing sorts every transaction into buckets — commonly three: qualified, mid-qualified and non-qualified — and charges a different rate for each. The rate on the proposal is the qualified one. It is the cheapest and, for most businesses, it is not the one most sales are charged.

The surcharge is the difference. A sale that downgrades from qualified to non-qualified is charged the qualified rate plus a non-qualified surcharge, and that uplift is where tiered pricing earns its margin.

What causes a card to downgrade

Almost none of it is about you.

The card the customer carries. Rewards cards, business cards, corporate purchasing cards and most commercial cards cost the processor more at interchange, so they are placed in a higher tier. A customer who pays with an airline-miles card has, from your till’s point of view, chosen a more expensive transaction. You cannot ask them not to.

Keyed entry. Taking a number over the phone or typing it in costs more than a dip or a tap, because the fraud risk is higher. That one is partly within your control.

Settlement timing. Batches left open past the processor’s cut-off can downgrade. This is genuinely your side of the line and worth fixing — close the batch every day.

Missing data. On keyed sales, not entering the billing postcode or address can push a transaction down a tier.

So of the four main causes, one is about customer behavior you do not influence, one is about how you take payments, and two are operational habits. The marketing for tiered pricing tends to imply the whole thing is operational. It is not.

Why the effective rate is the only honest measure

Here is the structural problem. A merchant is quoted “1.79%” and reads that as their cost. At the end of the month a meaningful share of volume has been charged at the mid tier and another share at the non-qualified tier, plus the monthly fees. The number that actually left the bank account corresponds to a considerably higher percentage of volume.

Neither figure is a lie. They simply describe different things, and only one of them is the cost of doing business.

Work out your own effective rate here — it needs two numbers and no email.

What to do about it

Fix what is yours to fix. Close your batch daily. Capture full card data at the terminal rather than keying where you can. Enter address and postcode on keyed sales. This genuinely reduces downgrades, and it is free.

Then stop treating the tiers as the problem. The tiers are a presentation of a cost that exists either way. A rewards card really does cost more to accept, under every pricing model. What differs is whether you can see that cost itemised or whether it reaches you as a bucket name and a surcharge.

Ask for the breakdown. A reasonable request to any processor: what percentage of last month’s volume settled qualified, mid-qualified and non-qualified? If the answer is slow or vague, that is informative in itself.

If most of your volume is downgrading, tiered pricing is not failing — it is working exactly as designed. The design is the thing to change.

The alternative

Under interchange-plus there are no tiers. The actual interchange for each card is passed through at cost and shown to you, with one agreed markup on top. A rewards card still costs more — it always did — but you see precisely how much more, and the processor’s margin is the same on every sale regardless of what your customer pulls out of their wallet.

That is the real difference. Not that one is cheap and one is expensive, but that one can be audited and one cannot.
