Custom software vs generic SaaS for an SME
Custom makes sense with a measurable bottleneck and a stable perimeter. SaaS is enough when the process is standard and you can adapt.
In short
Custom software is your product (code and data) for a specific process. Generic SaaS rents the same features to thousands of companies. Read cost over 24–36 months, not the first month’s fee.
- Custom MVP: typically €15–60k for a focused first release
- SaaS: fast if your process matches the vendor’s
- Useful quote: goal, users, systems, budget band
| Choice | When | Watch-out |
|---|---|---|
| SaaS | Standard process | Seats and lock-in |
| Custom MVP | One bottleneck | Do not clone a full ERP |
| Fuller custom | Process clear after MVP | Run cost and an internal owner |
Questions
How much does custom cost?
It depends on users, integrations and constraints. We use ranges, not a single list: see the calculator and the cost article.
Can we start small?
Yes: an MVP on one flow, then you decide the rest with usage data.
