Factor SaaS is better if... Open Source is better if...

**budget * * Planable monthly budget preferred Avoiding license costs in the long term

**IT resources * * IT department already heavily loaded Strong IT team with expertise available

**Needs * * Standard solution covers demand Specific needs

Conclusion: No One-Size-Fits-All

The decision between Open Source and SaaS is not a question of "better" or "bad" but a strategic review that depends on the custom circumstances of your SME.

For most SMEs without large IT department, a carefully selected SaaS solution is often the more pragmatic and more economical way.

The rapid start and low internal effort weigh up the running costs.

For technologically skilled SMEs with specific needs and a strong focus on data sovereignty, an open source solution can be the superior alternative in the long term.
