A SaaS platform (Software as a Service) is a cloud based software delivery model where applications are hosted on remote servers and provided to users as an online service, without requiring installation or hardware management. Users simply log in through a browser or app, while updates, security, backups, and infrastructure are fully handled by the provider.

Examples of SaaS platforms include CRM systems, ERP modules, payment solutions, project management tools, email marketing systems, analytics dashboards, e commerce services, HR management platforms, online booking tools, and global services such as Google Workspace, Dropbox, Slack, Shopify, and many more.

Key advantages of SaaS: no installation required, accessible from anywhere, low infrastructure cost, automatic updates, scalability, multi user access, and high level security. SaaS allows businesses to avoid server management and focus entirely on using the software.
