In 2025, more and more companies, associations and local authorities are thinking about modernising their internal management system. ERP (Enterprise Resource Planning or ERP in French) remains the central tool for effectively managing human resources, finance, logistics or event planning.
But a question arises: should you opt for a SaaS ERP (accessible online, in subscription mode) or stay on a classic ERP (installed on internal servers)?
In this comparison article, we will detail the differences, advantages and limitations of each solution, in order to help decision-makers make the right choice for 2025.
What is a classic ERP?
A classic ERP (also called “on-premise”) is installed directly on the company’s computer servers.
- License : one-time payment (often high).
- Hosting : management in-house or via a service provider.
- Maintenance : Requires an IT team to manage updates, backups, and security.
- Customization : very flexible, but often expensive.
Historically, it has been the preferred choice for large companies with a strong IT infrastructure.
What is a SaaS ERP?
A SaaS (Software as a Service) ERP is hosted in the cloud and accessible via the Internet, on a monthly or annual subscription.
- Cost : Per user per month, with no heavy upfront investment.
- Accessibility : available everywhere (computer, tablet, smartphone).
- Updates : Automatic, without tying up your teams.
- Security : managed by the SaaS vendor, often with advanced certifications (ISO, GDPR).
It is the modern choice for companies, associations and communities looking for more flexibility and speed of deployment.
SaaS ERP vs Classic ERP: Comparison Table
| Criterion | Classic ERP (On-Premise) | SaaS ERP (Cloud) |
|---|---|---|
| Initial cost | High (license + servers) | Low (subscription) |
| Maintenance | Intern / Contractor | Included and automated |
| Accessibility | Locale / VPN | Everywhere via the Internet |
| Security | Depends on internal IT | Certified Industrial Level |
| Updates | Complex, expensive | Automatic and regular |
| Deployment | Long (months/years) | Fast (days/weeks) |
| Scalability | Heavy, expensive | Flexible, scalable |
| Suitable for | Large structures with robust IS | SMEs, associations, modern communities |
What choice for 2025?
In 2025, the trends are clear:
- SaaS is attractive for its flexibility, speed of implementation and predictable cost.
- The classic one is resistant in certain very sensitive environments (banks, critical industries) where the data must remain completely internal.
👉 For the majority of companies and associations, SaaS ERP is the most relevant choice, as it allows:
- Reduced IT costs.
- Better remote collaboration (essential with remote work).
- Enhanced compliance with security regulations and GDPR.
