What is B2B SaaS? — UK Software Development Guide
Direct Answer
B2B SaaS (Business-to-Business Software as a Service) is a software delivery model where a company sells subscription-based software to other businesses rather than individual consumers. B2B SaaS products typically have higher average contract values (ACV) than B2C, longer sales cycles, and more complex feature requirements (SSO, audit logs, admin dashboards, bulk user management).
