Restaurant POS Software: A Guide for the Hospitality Industry

An efficient restaurant requires a powerful Point-of-Sale System (POS) to efficiently manage orders, payments, and inventory. Modern POS systems automate these processes, contributing to the improvement of customer service and optimization of business operations.

But which solutions are the best? This article provides a comprehensive overview and shows how an integration with Sundae OS can further optimize operations.

How does a POS system work?

A POS system combines hardware and software to manage transactions and operational processes in restaurants. The key features are:

  • Order Management: Immediate capture and forwarding of orders to the kitchen.

  • Payment Processing: Support for various payment methods such as cash, credit cards, and mobile payments.

  • Inventory Control: Real-time monitoring of stock for better planning.

  • Sales Analytics: Creation of detailed reports to optimize the business.

Integration of Sundae OS with POS Systems

The connection between a POS system and Sundae OS provides an even more efficient workflow. The following interfaces significantly enhance restaurant management:

  • Automated Labour Cost Calculation: Sundae OS synchronizes employee working hours with the POS system to calculate labour costs in real-time.

  • Revenue and Cost Analysis: Through integration with POS systems like Lightspeed, Square, or Toast, revenues can be matched with labour costs, allowing for monitoring the ratio of labour costs to revenue.

  • Shift Planning with Sales Forecasting: Sundae OS can use historical POS data to optimize shift schedules based on sales forecasts. For example, during expected peak times, more employees are automatically scheduled.

  • Inventory Management: An extension is planned in the future to align inventory data between Sundae OS and POS systems. This allows restaurants to trigger reorder requests in a timely manner when stock levels are running low.

Advantage: By integrating Sundae OS with a POS system, restaurants save time, reduce sources of error, and gain a complete overview of costs.
