Magic Happens Here
ONUS is designed to turbocharge all your operations with a one-stop, centralized POS software solution — powered by AI, built by store owners.
One platform. Four divisions.
Everything we build starts with you.
ONUS isn't a single product — it's a complete platform for running a modern store, backed by people who've actually done it. Here's what sets us apart.
Built by retailers, for retailers
We spent 22+ years behind the counter before we wrote a line of code. ONUS solves the problems we lived — not the ones a boardroom imagined.
One partner for the whole store
Inventory, Merchant Solutions, Zero, and Fee Guard under one roof — one team, one login, one number to call instead of five vendors.
Real human support, 24/7
When something matters at 9pm on a Saturday, a real person picks up the phone — not a ticket queue and not a chatbot.
Honest pricing, no lock-in
Month-to-month plans, transparent rates, and no surprise fees. You stay because ONUS works for you — never because a contract traps you.
Built to grow with you
From a single shop to a chain of locations, ONUS scales with you — and keeps getting better through updates driven by what customers ask for.
Your success is the scorecard
Hands-on onboarding, training, and a team that measures itself by your results — because when your store wins, so do we.
Made for the way you sell.
ONUS is tuned for the realities of each industry it serves — not a generic register bolted onto your business.

Featured Review
“Look, I've tried Square, Toast, Liquor POS — they all work fine until Friday at 6pm. Then you've got 20 people in line and the terminal takes 4 seconds per tap. Doesn't sound like much until you're watching customers walk out. Switched to Onus in March. First weekend I noticed the difference. My guy at register 2 said 'this thing is fast' — and he never notices anything. The age verification is the other thing. We had ABC come through in April, asked to see our logs. Pulled it up in 10 seconds. Inspector was impressed, I was relieved. Is it perfect? No. The inventory sync was buggy the first week. But they fixed it fast and the support actually picks up the phone. Try getting that from Square.”
