SaaS (Software as a Service) is a cloud computing model delivering software applications via the Internet. Unlike traditional installations, retailers access the software through a web browser, eliminating the need for on-premise infrastructure. This approach offers scalability, regular updates, and accessibility from various devices. In retail, SaaS is prevalent for point-of-sale systems, inventory management, CRM, and other operational tools. It enhances efficiency and flexibility in managing retail operations by providing a streamlined and accessible technology solution.
