About Onus
We make checkout
disappear.
Founded by retail operators who got tired of slow terminals and clunky software. We build payment systems that get out of the way.
The backstory
In 2019, our founder Marcus ran three liquor stores in Atlanta. Every Friday night, lines backed up. Not because of customers — because of the payment terminal.
The existing solutions were built for coffee shops and boutiques. They looked pretty but couldn't handle a rush. Age verification was an afterthought. Inventory sync was a joke.
So we built our own. Hardware and software, designed together, specifically for high-volume retail. Liquor stores first, then convenience, then smoke shops.
Today, we process over 2 million transactions daily across 500+ locations.
Timeline
What we believe
Three principles.
No fluff.
Speed over features
Every second at checkout matters. We optimize for the transaction, not the demo.
Hardware matters
Software alone can't fix a bad terminal. We control the full stack.
Retail first
We don't build for restaurants or salons. Retail has different problems.
