There will be many important operational decisions you need to make for your restaurant and few are as daunting as choosing a POS. When it comes to POS systems, restaurateurs are spoilt for choice. Each system is designed to serve the same basic purpose: to record sales and returns. When it comes down to functionality, reliability, performance and capability, each system is unique. Price, warranty, technical support, future enhancements and after-sales service are the most basic things you need to consider and research before committing to a specific supplier.
