Your ISO Has No Record
You searched the company on your statement and found nothing. No rating, no lawsuits, no complaints, barely a website. That is not a clean record. It is an absence of one, and the two are not the same thing.
GUIDE NOT SCORED
A clean file on a small sales organization measures visibility, not conduct
Ratings agencies, review platforms and courts all work on the same input: volume. A company needs enough customers, for long enough, for a pattern to become visible. The Better Business Bureau needs complaints to grade. Review sites need reviewers. Class actions need a class.
An independent sales organization with a few hundred merchants and six employees generates none of that. Not because it treats those merchants well, and not because it treats them badly, but because a few hundred unhappy small businesses spread across nine states do not add up to a searchable record. They add up to a few hundred separate people who each assumed it was just them.
So when you search the name on your statement and find nothing, you have learned exactly one thing: this company is small enough to be invisible. You have learned nothing at all about your price.
Absence of evidence is the normal condition of a small sales organization. It is not evidence of good conduct.
weAudit reader guideWhere your price is actually set
There are three layers between your customer’s card and your bank account, and most merchants only ever meet one of them.
At the bottom sits interchange, set by Visa and Mastercard, paid to the bank that issued your customer’s card. Nobody in your supply chain keeps it and nobody can discount it. For most merchants it is the large majority of the total cost of accepting cards.
Above that sits the acquirer or processor, the licensed entity that actually moves the money and whose name is usually buried in the small print at the bottom of your statement. It sets a wholesale price, sometimes called a buy rate.
At the top sits the independent sales organization or agent, the company whose logo is on your paperwork and whose representative sat across your counter. It buys at the acquirer’s wholesale price and sells to you at whatever it decides. The difference is its income.
That last layer is where your price is set, and it is the layer nobody publishes anything about. This is not a secret or an allegation. It is how the industry describes itself to its own partners. Fiserv’s own sales organization partnership page tells prospective partners the programme “enables you to have more pricing flexibility when you choose to sell Fiserv products to merchants.” Pricing flexibility means exactly what it sounds like. The seller decides.
| Layer | Who sets it | Published? |
|---|---|---|
| Interchange | Visa and Mastercard | Yes, in full, on the card networks’ own websites |
| Acquirer wholesale price | The processor whose name is in your statement footer | No |
| Your markup | The sales organization that signed you | No, and no rule requires it to be |
The industry is not regulated, and pricing disclosure is not required
Merchant card processing is a non-regulated industry. There is no federal or state body that licenses a sales organization, approves its pricing, requires it to disclose a markup, or gives you a standardised disclosure document before you sign. There is no equivalent of a mortgage disclosure or an annual percentage rate.
What exists instead is card network registration. Visa and Mastercard require sales organizations working with their member banks to register, and Visa maintains a searchable Global Registry of Service Providers. That registry is worth checking, and we explain how below, but understand what it is: a compliance listing, largely built around data security validation. Appearing on it means a company completed a registration and validation process. It says nothing about what that company charges you, and it is not a complete directory of every agent selling merchant accounts in the United States.
The practical result is that the only enforceable description of your price is the contract you signed and the statement you receive every month. Those two documents are the entire disclosure regime. Most merchants have never read either one closely.
Reading the silence correctly
“They must be reputable”
A company can bill several hundred merchants for years, at any markup it likes, without ever generating a public record. Nothing about that is unusual and nothing about it is illegal.
“There is nothing to find”
The record that matters is not public. It is on your own statement, and it is specific to your account. Two merchants signed by the same agent in the same month routinely pay very different prices.
They are small, and you are on someone else’s paper
Your actual merchant agreement is almost certainly with a much larger acquirer and a sponsoring bank. The sales organization is a party to it, not the whole of it. That larger company does have a record, and it is on our board.
Nobody is watching the markup for you
No regulator reviews it, no rating covers it, and the acquirer whose rails you are on has no obligation to tell you what its partner added. Checking it is your job or your auditor’s.
Five steps that produce a real answer
-
Find the acquirer and the sponsoring bank
Turn to the last page of your monthly statement and read the small print. There is normally a line naming a member bank and a processor. That is who actually holds your account. Our companion guide, My Processor Rating Is Missing, walks through that disclosure line by line. Once you have the name, look it up on The Processor Scoreboard, because that company does have a documented record.
-
Calculate your effective rate
Every card related charge for the month, divided by total card volume for the month. One percentage. It is the only number that is comparable between providers, and it is the number no sales presentation ever leads with.
-
Ask for interchange to be shown separately
Interchange is published in full by Visa and Mastercard, so it can always be verified against the source. If your statement bundles it into blended tiers or internal codes, you cannot check the largest component of your own bill. Ask, in writing, for a statement that separates interchange from everything added on top.
-
Check the registration, and know its limits
Search the sales organization’s name on Visa’s Global Registry of Service Providers. A listing confirms the company completed registration and validation. It confirms nothing about your pricing. Treat an absence as a question to ask, not as proof of anything.
-
Read the term, the renewal and the exit before you renegotiate
Find the initial term, the automatic renewal window, the notice period and any early termination or liquidated damages clause. You cannot negotiate a price you have no ability to walk away from, and the renewal window is usually the only moment of leverage you get each year.
The point of this guide
Rate the company that holds your account, then audit the company that prices it
We do not rate small sales organizations, and we will not start, because a rating built on no evidence is worth less than no rating at all. What we can tell you is where to look instead. The acquirer behind your account is a large company with a public record, and that record is on our board. The markup on top of it is invisible to everyone except you, and it is visible to you only if you go and calculate it.
If your search came back empty, nothing is wrong with your search. You were looking in the only place where the answer was never going to be.
Your sales organization has no public record. Your statement has all of it.
weAudit audits merchant statements every month for a low fixed fee, never a percentage of what we find, and we accept no compensation from any payment processor. Send us a statement and we will tell you who holds your account and what has been added on top.
