Processor markup and pricing models
The only part of your rate that is actually negotiable. Interchange-plus vs tiered vs flat, and how markup hides.
Here is the whole secret of payment pricing in one sentence: interchange and assessments are the same everywhere, so the only thing you are ever really shopping is markup. Markup is your processor’s margin, the one negotiable number on the bill. Master the four ways it gets packaged and you will never be confused by a proposal again, because you will know exactly where the profit is hiding.
Markup is the margin on top of cost
Your processor’s true cost on a sale is interchange + assessments, both fixed, both identical for every provider. Whatever they charge above that is markup, their profit. A good processor earns a fair, visible margin. A bad one buries an enormous one inside confusing structures so you can never tell. The structure they choose is the single biggest signal of which kind you are dealing with.
One rule to carry around
Every processor uses one of these
There are exactly four ways markup gets packaged. Watch the same $100 rewards-card sale move through each, and watch how much you can, or cannot, see.
Interchange-plusThe transparent standard.
Transparency
5/5
Every component itemized. You can see and shrink the markup. Almost always cheapest for an established business.
Tiered pricing, and the downgrade game
Tiered pricing sorts your transactions into qualified, mid-qualified, and non-qualified buckets, each with its own rate. It sounds tidy. In practice it is a machine for quietly moving your sales into the pricier buckets, a “downgrade.” Rewards cards, corporate cards, keyed and online transactions all conveniently “don’t qualify,” landing in the non-qualified tier where the markup is fattest and totally hidden.[1]
- You can never compute your real markup, because interchange, assessments, and margin are blended into each tier.
- The processor controls which transactions “qualify,” so the deck is theirs to stack.
- The teaser “qualified” rate on the ad is the one almost none of your sales actually get.
If your statement says “non-qualified”
Interchange-plus, the standard to demand
Interchange-plus passes interchange and assessments straight through at cost and adds one clearly stated markup, written like “interchange + 0.25% + $0.10 per transaction.” Because the margin is a fixed, visible number, you can finally do three things you cannot do under tiered pricing: see it, compare it across providers, and negotiate it.
| What to ask for | Why it matters |
|---|---|
| Interchange-plus, in writing | Exposes the markup so it can be compared and shrunk. |
| The markup as "% + $ per transaction" | A fixed margin you can verify on every statement. |
| Pass-through interchange & assessments | Confirms the network costs are not being padded. |
| No "non-qualified" language | Confirms you are not secretly on tiered pricing. |
| All add-on fees listed | PCI, statement, batch, and minimums are negotiable too. |
Tiered vs interchange-plus on your volume
Typical tiered markup
$720
/ month (~1.2% hidden)
Interchange-plus markup
$210
/ month (~0.35% visible)
Same sales, same interchange. The difference, $510/mo ($6,120/yr), is pure markup you stop overpaying.
Illustrative spreads; your real markup depends on your statement.[1]
Flat-rate and subscription: when each fits
Not every business should chase the absolute lowest markup. Two more models earn their place:
- Flat-rate (one blended rate, e.g. 2.9% + 30¢): dead simple, predictable, no monthly fees. Great for brand-new or very low-volume merchants. The catch is it charges the same high rate on a cheap debit card as on a premium rewards card, so it gets expensive as you grow.
- Subscription / membership: interchange and assessments at cost, plus a small per-transaction fee and a flat monthly membership. Because the margin is a fixed dollar amount rather than a percentage, it can be the cheapest option of all for high, steady volume.
Rule of thumb
What to actually do Monday morning
You do not need to become a payments expert. You need to force the markup into the open and make providers compete on it:
- Ask your current processor for your effective rate and your markup, in writing. Watch how they react.
- Request interchange-plus pricing with the markup stated as “% + $ per transaction.”
- Get the add-on fees, PCI, statement, batch, monthly minimum, itemized and negotiate them too.
- Compare providers on markup and effective rate only, never on a teaser “qualified” number.
The bottom line
- Markup is the processor’s margin and the only negotiable part of your bill.
- There are four models: interchange-plus, tiered, flat-rate, and subscription.
- Tiered pricing hides markup inside qualified/non-qualified buckets and is usually the most expensive.
- Interchange-plus shows the markup as a fixed "% + $" you can see, compare, and lower.
- Demand interchange-plus in writing, itemize the add-on fees, and compare only on markup and effective rate.
