SaaS (Software as a Service) is a software distribution model where applications are hosted in the cloud and accessed via the internet on a subscription basis, eliminating the need for local installation.
SaaS has become the dominant software delivery model, offering advantages like automatic updates, scalable pricing, and accessibility from any device. Popular SaaS categories include CRM, project management, accounting, and communication tools. The subscription model provides predictable costs and eliminates upfront licensing fees.
SaaS has fundamentally changed how businesses buy software. You can now access enterprise-grade tools for $10-50/month that used to cost thousands upfront. But the flip side is subscription fatigue — costs add up fast.
A 10-person startup runs their entire business on SaaS: Slack for communication, Notion for docs, HubSpot for CRM, and QuickBooks for accounting. No servers, no IT team, no software installations — just browser tabs and monthly subscriptions.
SaaS isn't always cheaper than on-premise software. For large enterprises, the cumulative subscription costs over 5-10 years can exceed a one-time license. Always calculate total cost of ownership.
Audit your SaaS stack quarterly. Most businesses pay for tools they barely use. Cancel or downgrade anything with less than 3 active users in your org.
