Self-Hosting vs. Cloud ERP: Which Is Better for SMEs?
3 min read
Most ERP providers today sell their software as a cloud service (SaaS). Yet for many small and medium-sized enterprises, that is not automatically the best choice. This article compares both models factually — without marketing hype — and helps you put them in perspective.
What does self-hosting mean for an ERP?
With self-hosting (also known as on-premises), you run the ERP software on your own or self-rented infrastructure — for example, on a server in your own premises or with a German hosting provider of your choice. The software is purchased as a licence rather than rented. All data remains within your area of responsibility.
With cloud ERP (SaaS), the software runs on the provider’s servers. You pay a recurring fee, usually usage-based, and access the system through your browser. The provider takes care of operations and updates — but also has access to the infrastructure on which your data resides.
The direct comparison
| Criterion | Self-Hosting | Cloud ERP (SaaS) |
|---|---|---|
| Data sovereignty | Fully with the company | With the provider (often data processing) |
| Cost model | Licence + your own infrastructure, predictable | Recurring fee, often per user/usage |
| Operations & maintenance | Your own responsibility | With the provider |
| Customisability | High (full control) | Limited by the provider |
| Dependency | Low | High (provider lock-in) |
When self-hosting is the better choice
Self-hosting is particularly worthwhile when:
- Data protection is a central concern. Sensitive customer, personnel, or financial data never leaves your infrastructure. You remain the controller under data protection law, without having to involve a provider cloud.
- You want predictable costs. A licence with a fixed base fee can be budgeted over years — unlike usage-based cloud plans that rise as you grow.
- You want to stay independent. No provider can block your access, unilaterally raise prices, or discontinue the service while your data sits with them.
When cloud ERP can make sense
Cloud ERP plays to its strengths when a company does not want to provide any IT resources at all for operations and backups, and is willing to give up part of its data sovereignty and cost control in return. For very small teams without any technical support, this can be a viable path.
The middle ground: licence + free choice of hosting
An often-overlooked third way: software as a licence that you host yourself — either on your own premises or in a German data centre. This way, you retain data sovereignty and can still outsource operations to a service provider if you do not have your own IT team.
This is precisely the model that VertooERP pursues: the platform is sold as a licence and hosted by the customer — with full data sovereignty, GDPR- and GoBD-compliant (GoBD are the German principles for the proper keeping and retention of books and records in electronic form). This keeps control over the data with the company, without sacrificing flexibility.
Conclusion
There is no answer that is universally correct. Those who prioritise data sovereignty, predictable costs, and independence are usually better served by self-hosting or a licence model with a free choice of hosting. Those who want to hand over all technical responsibility, and trade control for that convenience, will find cloud ERP a comfortable entry point. What matters is holding the criteria honestly against your own situation — rather than following the industry trend.
