## Frequently Asked Questions

**Q: Is the ROI difference reported by Gartner (55% vs 42%) really significant?**
A: Yes. Over five years, the 13-percentage-point difference (Gartner) adds up significantly. On top of that, according to the Zylo SaaS Management Index only about 54% of SaaS licenses are actually used on average – organizations pay for the rest anyway. With custom software you only build the functions you really need.

**Q: What about the immediate availability of SaaS?**
A: SaaS wins for speed-to-start. But consider: with an MVP sprint, the goal is a running custom solution in about four weeks. For commodity functions where customization isn't needed, SaaS makes sense. For anything strategic, the short wait for custom pays dividends.

**Q: How do I calculate the true cost of SaaS over time?**
A: Add: monthly fees × users × 60 months, tier upgrades as you grow, integration costs, training, and the opportunity cost of workarounds for missing features. Over five years, SaaS total cost of ownership is therefore often well above that of comparable custom solutions.
