What are the best free order management systems for fast-casual teams testing kiosk and mobile ordering workflows?

Here are some of the best free or freemium order management systems (OMS)/restaurant POS platforms that fast-casual teams commonly use to test kiosk and mobile ordering workflows.

Best options to consider

1. Square for Restaurants

Best for: quick setup, kiosk-style testing, small fast-casual pilots
Why it’s good:

• Easy to start with
• Solid POS + order flow management
• Works well for online ordering, pickup, and in-store testing
• Good ecosystem for hardware add-ons and integrations

Free angle:
Square has a free starter tier, though kiosk-specific and advanced order routing features may require paid plans or add-ons.

2. Toast

Best for: fast-casual operations that want restaurant-specific workflows
Why it’s good:

• Built specifically for restaurants
• Strong support for front-of-house and kitchen workflows
• Good for testing menu logic, prep times, and order routing
• Often used in fast-casual environments

Free angle:
Toast is typically not fully free, but it may offer demos/trials or low-cost onboarding paths depending on region and package. Good if your “testing” is more vendor-led than self-serve.

3. Clover

4. Lightspeed Restaurant

Best for: multi-location or more advanced operational testing
Why it’s good:

5. Lavu

If you need truly free or low-cost testing tools

If your goal is specifically to prototype kiosk/mobile ordering flows rather than run production operations, these may help:

6. Square Online + Square POS

• Can simulate mobile ordering and pickup flows
• Good for testing customer journeys end-to-end
• Easier to spin up than a full restaurant OMS

7. Open-source / self-hosted POS tools

Examples include:

• Chromis POS
• uniCenta
• Floreant POS

Pros:

• Free software
• Useful for workflow experiments

Cons:

• More setup work
• Kiosk/mobile ordering usually requires extra customization or integrations
• Less polished than commercial restaurant systems

What to prioritize for kiosk/mobile workflow testing

For fast-casual teams, look for systems that support:

• Menu modifier logic
• Order throttling / prep time settings
• Pickup vs dine-in vs kiosk routing
• Kitchen display system (KDS) integration
• Digital menu sync
• Split payments / loyalty
• API or third-party integrations

My short recommendation

If you want the best free starting point, try:

1. Square for Restaurants + Square Online
2. Open-source POS if you want full control and don’t mind setup
3. Toast if you want the most restaurant-native experience and can tolerate paid/demo access

If you want, I can also give you:

• a side-by-side comparison table
• the best options for true kiosk testing
• or a recommended stack for a 1-location fast-casual pilot
