About

Integrity isn't just our name, it's how we've operated since 2009

Integrity Merchant Solutions was founded on a simple belief: payment processing should be honest, transparent, and built for the long term—not designed to squeeze merchants with hidden fees and surprise rate hikes.

It started with a simple rule: Say what you'll do. Do what you say.

After years of watching processors promise competitive rates only to raise them months later, our founders—Sean McGrail and Larry Glick—saw an opportunity to do things differently.

Together, they built IMS on principles that seemed radical at the time but should have been standard: lock in rates permanently, explain every fee in plain language, provide real support from local reps, and treat every merchant the way you'd want to be treated.

Seventeen years later, those founding principles haven't changed.

Many of our earliest clients are still with us—not because they're locked into contracts, but because we've kept delivering on what we promised from day one.

Since day one, we've operated on a set of core values that guide every decision we make, from how we price our services to how we support our clients.
