About Rhombus POS
Built to serve small businesses — especially those that have too often been overlooked or underserved by traditional technology and financial systems.
Our Mission
We believe every merchant deserves access to tools that are dependable, affordable, and straightforward to operate. Our mission is simple: to help business owners stay in control, keep more of what they earn, and grow with confidence.
Versatile by Design
A True Restaurant and Retail Hybrid Platform
Rhombus POS was built with the understanding that many merchants do not fit neatly into one category.
Whether a business is serving meals, selling products, or doing both, Rhombus provides one flexible system to support the entire operation.
Technology should adapt to the merchant — not the other way around.
Built for Commerce Anywhere
The way people do business has changed, but the needs of merchants have not. Owners still need reliability, clarity, and the ability to operate smoothly day after day.
Rhombus was designed for businesses that require flexibility across locations, business models, and real-world working conditions. Our goal is to provide merchants with a POS platform that is practical, modern, and built to last.
Freedom Without Lock-In
Rhombus POS is both hardware-agnostic and processor-agnostic, giving merchants the freedom to operate in the way that best fits their business.
No Proprietary Equipment
Use industry-standard devices and hardware
No Forced Leasing
Own your equipment, no mandatory contracts
No Limitations
Choose what serves your business best

Our Story
Built on Trust and Experience
Rhombus POS was founded by Michael Hogan, an engineer who spent decades working in critical infrastructure and system controls. After retirement, he established Rhombus POS with a clear purpose:
To ensure small business owners are treated as partners — not just transactions — within the financial technology system.
"Rhombus POS is about you, not about us."
That commitment to responsibility, fairness, and long-term reliability continues to guide everything we build.
