The Open Commerce Platform
for Modern Merchants
Run your business on the devices you want, work with the payment processor you choose, and manage retail and food operations in one flexible platform.
Rhombus connects your devices, payments, and business tools — without locking you into proprietary hardware or payment contracts.
The Rhombus Platform
One Platform Connecting Your Commerce Technology
Most POS systems force businesses into closed environments. Rhombus was built differently.
Rhombus sits at the center of your business technology — connecting devices, payment providers, and operational tools into one flexible system.
Hybrid Commerce
Built for Businesses That Don't Fit the POS Box
Many businesses today operate across multiple models. Traditional POS systems force merchants into either retail or restaurant workflows. Rhombus supports both.
If your business combines multiple types of sales, Rhombus adapts to your workflow.
Freedom by Design
Your Business Should Control Its Technology
Rhombus was built on a simple principle: your business should control its technology — not the other way around.
Run on the Devices You Choose
Rhombus works across iOS, Android, and Windows. Use tablets, phones, or terminals that best fit your operation.
Choose Your Payment Processor
Most POS systems force merchants into one payment provider. Rhombus allows you to work with the processor you trust — maintain existing relationships, negotiate better rates, and avoid long-term lock-in.
Designed for Hybrid Commerce
Retail and food operations can run side-by-side. Manage retail inventory, prepared food items, custom orders, and mobile sales — all from one platform.
The Platform Advantage
Why Rhombus Is Different
Most POS systems control your entire environment.
Secure by Architecture
Rhombus was designed with security and flexibility in mind. The platform keeps sensitive payment data outside the core system, helping reduce PCI compliance scope while still allowing merchants to work with multiple payment providers.
Security and flexibility should not be mutually exclusive. Compliance requirements vary by business — Rhombus supports secure payment flows, but merchants must still follow PCI best practices.
For Partners
Build Your Merchant Solutions on the Rhombus Platform
Payment companies, resellers, and technology providers can deploy their own branded POS solution using the Rhombus platform — without building software from scratch.

Frequently Asked Questions
Everything You Need to Know
Do I have to sign a long-term contract?
No. Rhombus is built for month-to-month flexibility. You are not trapped in a multi-year agreement, and there are no early termination fees.
Can I use my own hardware?
Yes. Rhombus supports non-proprietary hardware so you can reuse what you already own — iOS devices, Android tablets, Windows PCs, and industry-standard peripherals like printers, scanners, and cash drawers.
Does Rhombus work for restaurants AND retailers?
Yes. Rhombus is designed for retail and restaurant workflows — and hybrid businesses that do not fit neatly into one category. One system, one subscription, both verticals.
What happens if the internet goes down?
Rhombus supports offline operation so you can continue selling during outages and process transactions once connectivity returns. Optional LTE is also available for mobile reliability.
Can I choose my payment processor?
Rhombus is built to support multiple processing options, so you are not locked into one provider. Choose the processor that gives you the best rates and terms.
Is support included?
Yes — all plans include 24/7 Rhombus support. You can also work with a local Rhombus-certified reseller or your own IT team for on-site assistance.
Does pricing include hardware or processing?
Pricing covers software only. Hardware and payment processing are separate, so you remain in control of your setup and costs — no forced bundles.
