Exclusively for businesses doing $100K to $500K per month

Do You Actually Know
What You Pay on
Every Transaction?

Most business owners at your volume have no idea. Their processor is counting on that.

At $100K to $500K per month in processing volume, a difference of just one percent in your effective rate is worth $1,000 to $5,000 every single month. We audit your statement for free, name every fee line by line, and show you exactly what a business your size should actually be paying.

Who We Work With

Built for businesses doing real volume.

We focus exclusively on merchants doing $100K to $500K per month. At that volume, the fees are significant enough to matter and the savings are real enough to change your bottom line.

Auto Repair Shops

High ticket transactions, consistent monthly volume, and owners too busy to read a statement closely.

$100K to $400K/mo

Medical and Dental

Practices with billing departments that process serious volume every month and rarely question the fees.

$150K to $500K/mo

Home Services

Contractors, HVAC, plumbers, and roofers processing large tickets where every basis point adds up fast.

$100K to $350K/mo

Specialty Retail

High transaction frequency means a small rate difference compounds into thousands every single month.

$100K to $500K/mo
The Real Problem

Your processor designed your statement to be confusing.

That is not an accident. The more complicated the statement, the less likely you are to question it. Here is what is actually hiding in there.

Junk fees with official-sounding names

PCI non-compliance, regulatory fees, network access fees. Most are negotiable or completely invented.

Rate creep that happens quietly

Processors raise rates gradually in small increments, knowing most merchants never look closely enough to catch it.

Misclassified transaction types

Card types get miscategorized in ways that cost you more. It happens quietly and compounds over time.

What a 1% rate difference costs a business at your volume
$1,000
At $100K/month, 1% is $1,000 per month. That is $12,000 per year walking out the door.
$2,500
At $250K/month, the same 1% costs $2,500 monthly. Over two years that is $60,000.
$5,000
At $500K/month, a 1% overpayment is $5,000 every single month. That is a full-time employee salary.

"One of the most transparent and results-driven merchant advisors in the region."

I had been with the same processor for 6 years and figured my rate was fine. Rodney showed me in 20 minutes I was leaving $1,800 a month on the table. The switch took a week and I have not looked back once.

We do $280K a month and I figured we were too big to be getting overcharged quietly. Rodney found $1,600 in fees we were absorbing every single month. Complete eye opener for our whole team.

We review a limited number of audits each month.
Your volume range is prioritized.

We work with a select group of merchants at a time so every audit gets the attention it deserves. Businesses doing $100K to $500K per month are moved to the front of the queue. Spots fill quickly. Every month you delay the audit is a month of overpayment you cannot get back.

Common Questions

Everything you are probably
already wondering.

Straight answers. No runaround.

What exactly is a merchant statement audit?

We take your most recent processing statement and break it down line by line. We calculate your effective rate (total fees divided by total volume), identify every fee by name, flag the ones that are unnecessary or inflated, and compare your current costs to what your volume qualifies for on our network. You get a clear picture of where your money is going and whether it needs to change.

How long does switching processors actually take?

For most businesses in your volume range, the switch takes 5 to 10 business days from the time you sign. We handle all the paperwork and the technical setup. You do not need to cancel anything yourself beforehand. Your terminals and systems get updated during the transition so there is no gap in your ability to take payments.

What if I am locked into a contract with my current processor?

We still run the audit. Knowing your real number now puts you in a position to make a decision the moment your contract expires instead of starting from scratch. In some cases, depending on your processor and contract terms, the savings are significant enough to justify the early termination fee. We will show you that math as part of the audit so you can decide for yourself.

What if my current rate turns out to be competitive?

We tell you to stay where you are. That has happened before and we will say it straight. The goal of the audit is to give you accurate information, not to move every merchant we talk to. If your processor is genuinely giving you a good deal, you will leave the audit knowing that for certain. That is worth something on its own.

Do I need to have my statement ready before I fill out the form?

No. Fill out the form now and we will walk you through getting the statement when we connect. Most processors make it available through your online portal or they can email it on request. We will help you locate it if you are not sure where to look. Do not let that stop you from submitting today.

Is there any cost or obligation at any point?

The audit is completely free. There is no obligation to switch, no contract to sign, and no pressure applied at any point. We show you the numbers and the decision is entirely yours. If you decide to move forward with a switch, we handle everything and the savings speak for themselves. If you decide to stay, you leave knowing your real rate and we part on good terms.

Who actually processes the payments after I switch?

We place merchants on a global enterprise processing network that handles over $1 trillion in annual volume across 200 markets worldwide. It is the same infrastructure used by Fortune 500 companies, with 99.999% uptime, AI-powered fraud protection, and 720 payment methods supported. Your payments run on a network built for scale, which is exactly how we access the rates we do.

How is Harris Merchant Advisory different from every other processor that calls me?

Most processors call you with a rate and ask you to trust them. We do not ask for trust. We show you your actual numbers first, compare them against what you qualify for, and let the math make the case. We also work with a select number of merchants at a time so the attention you get is real, not a sales call handed off to a junior rep. And we will tell you to stay with your current processor if the numbers say so. Try finding another ISO that will do that.
