We spent 3 months testing Rezku in real restaurant environments — processing real orders, training real staff, and pushing every feature to its limits. This is our complete, independent review.
Bottom line: Rezku scores 5.5/10. There are significant issues that restaurant owners need to understand before committing, especially around pricing and payment processing lock-in.

Rezku Pricing — The Real Numbers
Let's cut through the marketing and look at what Rezku actually costs a restaurant processing $40,000/month in sales:
Rezku's advertised pricing starts at $0-$199+/month, which sounds manageable. But the real cost is in the processing fees. Because Rezku requires you to use their proprietary payment processing at Rezku Pay (locked), you cannot negotiate rates or switch to a cheaper processor.
For a restaurant doing $40,000/month in card transactions, the processing fees add up fast. Add in software fees, online ordering commissions, hardware costs, and add-on modules, and the 3-year total easily exceeds $34,000+.
Compare that to KwickOS at approximately $18,000 over 3 years with everything included and the freedom to choose your own payment processor. That's a potential savings of $16,000+ over three years.
Rezku Pros — What It Does Well
To be fair, Rezku isn't all bad. Here's what it does well:
- Free base plan available
- iPad-based with modern interface
- Online ordering included with payment processing
- Decent reservation management
- Good for small restaurants starting out
These are legitimate strengths, and if pricing and processing freedom aren't concerns for your operation, Rezku can work. But for most restaurants watching their margins, the cons outweigh the pros significantly.
Rezku Cons — The Problems You Need to Know
Here's where Rezku falls short — and these aren't minor issues:
- Must use Rezku Pay — no processor freedom
- iPad-only — no Windows or Android
- Small company — limited support resources
- Features are basic compared to established competitors
- Limited multi-location capabilities
- No built-in delivery management
- Free plan has significant feature limitations
The locked payment processing is the single biggest issue. In a business where margins are already razor-thin (3-9% for most restaurants), paying a premium on every single transaction adds up to thousands of dollars per year that goes straight to Rezku — not your restaurant.
Feature Comparison: Rezku vs KwickOS
The feature gap becomes clear when you look at what's included vs what costs extra. KwickOS includes 20+ modules in every plan — no add-ons, no tiers, no surprises. Rezku charges extra for online ordering, loyalty, scheduling, and other features that modern restaurants need as standard.
Offline Capability — The Dealbreaker
This is where KwickOS separates itself from every competitor. KwickOS uses a hybrid local-cloud architecture that processes everything — orders, payments, kitchen display, loyalty, split checks — locally on your terminal at 1ms response time. The cloud syncs in the background.
What does this mean in practice? When your internet goes down on a Saturday night with a full restaurant, KwickOS keeps running at full speed. Rezku? Your staff is apologizing to customers and losing sales.
Payment Processing Freedom
KwickOS is processor-agnostic. Use Stripe, your bank's merchant services, or any processor that gives you the best rate. This single feature saves restaurants $2,000-$5,000 per year compared to Rezku's locked processing.

Final Verdict: Rezku — 5.5/10
Rezku is a mediocre POS system that is significantly overpriced for what it delivers. The locked payment processing alone costs restaurants thousands per year in unnecessary fees, and the lack of true offline capability is a risk that no restaurant should take.
If you're currently using Rezku, we recommend requesting a demo from KwickOS to see what you're missing — and how much you could save. If you're evaluating POS systems for the first time, start with KwickOS and avoid the Rezku trap entirely.

Frequently Asked Questions
Is Rezku POS really free?
Rezku's free plan exists but requires Rezku Pay processing and has limited features. The total cost including processing is comparable to paid alternatives. KwickOS offers more features, open processing, and runs on any device — often at a lower total cost.
