What is SaaS ROI?

For buyers, SaaS ROI is the return on subscription plus implementation versus the value you expect—usually time saved at a wage, or incremental revenue, net of ongoing fees over your analysis horizon.

How to justify software purchases

Build a single table: assumptions (who is affected, hours or dollars), annual value, all-in cost (license, services, internal PM time if material), and payback on upfront implementation. Compare to doing nothing and to the next-best alternative.

Common mistakes (overestimating time savings)

Teams often plug in “theoretical” hours saved before adoption stabilizes. Cut the first estimate by 30–50% for ramp and exceptions, or run a pilot cohort and measure actual hours for one month before scaling the model.

ROI vs cost savings vs revenue impact

Cost savings reduce spend you already have. Revenue impact adds new margin—often harder to prove. ROI should use one consistent numerator (either fully loaded labor value or attributable revenue) and the same denominator (total cost of ownership), or finance will reject the story.
