Why Onyx

Two screens. Twice the trust.

The customer-facing display turns every transaction into a brand moment — itemized receipts, loyalty prompts, tipping, and trust, all visible to your guest in real time.

Dual display

One screen for you.
One for your guest.

The operator screen is a full POS. The 15.6" customer-facing screen mirrors items, totals, and a branded checkout experience your guest sees at eye level — no more squinting at a tiny add-on.

Live itemized cart visible to the customer
Tipping & loyalty prompts on the second screen — no awkward terminal flip
Branded idle screen doubles as in-store advertising

Complete kit

Open the box.
Start ringing up.

Onyx ships as a complete checkout station. No piecing together a printer here, a scanner there — every part is matched, tested, and ready out of the box.

58mm thermal receipt printer with auto-cutter (80mm upgrade available)
Sealed cash drawer with key, integrated to the printer
Barcode scanner for retail-grade speed

FAQ

Everything you'd ask before buying.

Is the software really free with no monthly fee?

Yes. Restaurant or Retail software is included with every Onyx station for life. There's no monthly fee, no per-feature upsell, and no expiration. You also get free updates and bilingual support, indefinitely.

How fast does it ship and from where?

Free shipping ships within 5 business days. Orders are fulfilled from whichever of our two warehouses is closer — Toronto for Canada and the US Northeast, Las Vegas for the US West, Southwest, and Mexico.

What if it doesn't work for my business?

You have 30 days to return it for a full refund — no questions, no restocking fee. The unit also comes with a 1-year hardware warranty, so any defect during normal use means a replacement on us.

Can I switch between Restaurant and Retail later?

Yes. The license is a single account that lets you flip the station between Restaurant and Retail at any time. Most users pick one, but a few of our customers (like a café-and-shop hybrid) run both.

Does it work offline?

Yes. Onyx runs in hybrid-cloud mode — the station keeps selling, printing, and tracking inventory even if your internet drops. Once you're back online, everything syncs automatically.

I run multiple stores. Can Onyx scale?

Absolutely. Onyx supports multi-store inventory, multi-currency, and consolidated reporting. We also discount volume orders starting at 3 stations — request a quote and we'll size it for you.
