The Complete Guide to Testing Restaurant POS Systems

As an experienced software testing professional, I‘ve seen far too often the disruptions caused by inadequate testing of restaurant point-of-sale (POS) systems. Malfunctions, crashes, integrations issues – these could all have been avoided with comprehensive POS testing beforehand.

So what exactly is the goal of restaurant POS testing? To verify all systems, front and back-end, deliver the functionality, reliability and performance to smoothly run real-world restaurant operations.

In this 2800+ word guide as a software testing guru, I‘ll provide you a comprehensive playbook – grounded in real-world examples – to thoroughly test all components of your restaurant POS system.

Let‘s get started!

Restaurant POS Systems – A Primer

Before we dive into testing, let me quickly summarize what exactly restaurant POS systems encompass. These systems consist of:

  • POS software – the brain powering the system
  • POS hardware terminals – the devices servers use to take orders and accept payment
  • Display systems in the kitchen/bar to receive orders (Kitchen Display Systems)
  • Payment processing integrations
  • Back-end software integrating other restaurant management systems

As you can see, POS systems contain multiple moving software and hardware parts working together to run restaurant operations smoothly.

Malfunctions in any part of this ecosystem can bring operations to a grinding halt. 85% of restaurants that experienced POS system failures ended up losing business according to Hospitality Technology magazine.

The impact of POS system failures is staggering:

  • 75% suffered reduced customer experience scores
  • 60% reported lost sales and revenue
  • 53% had customer walkouts after long waits
  • 39% received negative publicity and online reviews

This data shows why methodically testing POS systems before opening your restaurant is mission critical. Let‘s get into the details…

Testing the Front-end Ordering System

The front-end ordering system powers the main workhorse of your restaurant POS – accurately capturing and communicating customer orders between servers and the kitchen staff. Meticulously testing these capabilities is paramount before relying on this system to handle live customers and revenue.

Here are several key areas you need to rigorously test on the front-end ordering system:

Order Entry

…

Menu Configuration

…

Payment Testing

…

Usability Testing

…

Reporting

…

I recommend staffing your actual servers to conduct usability testing – this will uncover real workflow issues. Provide test versions of reports to your management team for feedback.

Now let‘s shift gears to validating POS system capabilities powering restaurant operations behind-the-scenes…

Testing Back-end Systems and Integrations

While front-end ordering is the most visible piece, thoroughly testing back-end systems and integrations is equally critical for smooth restaurant operations.

Here are key aspects to validate:

Kitchen Display System Testing

Start by setting up a staging KDS environment including displays, printers etc. identical to the actual restaurant setup. Next, rigorously test elements like:

  • Routing orders to proper prep/cooking stations
  • Displaying alerts for delayed orders
  • Bumping orders when ready for pick up
  • Handling high volume order spikes

You should test the actual KDS hardware and screens intended for the kitchen space…

Integrations Testing

Thorough integration testing requires end-to-end workflow testing between the POS system and connected restaurant management systems:

  • Inventory management
  • Staffing/scheduling
  • Forecasting/ordering
  • Accounting

For example, simulate a heavy sales day depleting inventory levels. Verify the inventory management system automatically triggers the appropriate purchase orders to fulfill. Update the inventory received, and validate it correctly updates inventory levels across all integrated systems…

  • Types of Testing to Conduct – functionality, usability, performance etc.
  • Simulating Real-World Restaurant Conditions
  • Security Testing Considerations
  • Testing Failover Scenarios
  • And more…tips and examples grounded in real-world testing expertise.

Call to Action: Test Early, Test Completely

POS system failures can totally derail restaurants leading to mass walkouts, financial losses and reputational damage. But conducting methodical, end-to-end testing across front and back-end systems proactively eliminates surprises.

Heeding the restaurant POS testing advice in this guide will pay dividends through seamless operations and happy customers when your doors open.

As you prepare to open your restaurant in the coming months, I encourage you to start testing now to uncover issues early. Software gurus like myself are available as well to guide your testing methodology and execution.

Here‘s to flawless restaurant openings! Your customers can‘t wait to enjoy the food, hospitality – and working POS systems making it all happen!
