Cost and Value
Real Savings Without Sacrificing Power
Rhombus delivers real-world cost advantages because you:
Pay for What You Need
Modular pricing means you start simple and add features as you grow — no forced bundles or surprise charges.
Reuse Hardware You Already Own
No proprietary equipment required. Run Rhombus on iOS, Android, or Windows devices you already have.
Negotiate Your Own Rates
Choose your payment processor and negotiate directly — no locked-in rates or mandatory processing fees.
Avoid Long-Term Commitments
Month-to-month pricing with no early termination fees — avoid ballooning costs and stay flexible.
Reduce PCI Burden, Stay Secure
Rhombus is designed so sensitive cardholder data never sits in your system — helping reduce your PCI/DSS compliance scope and simplify security responsibilities. You still follow PCI best practices, but this architecture can lower your security footprint and compliance workload.
Less exposure. Less complexity. Stronger security. Compliance requirements vary by business — Rhombus supports secure payment flows, but merchants must still follow PCI best practices.
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.
