In 2025, entrepreneurs have an immense choice to manage their business: solutions SaaS (Software as a Service) on the one hand, and traditional software to be installed on the other.
But which of these two models is best suited to your business? To answer, let's compare their advantages, limitations, and the most relevant use cases.

What is SaaS?

One SaaS is an application hosted in the cloud and accessible online via subscription.
Famous examples: Salesforce (CRM), HubSpot (marketing), Notion (organization), Shopify (e-commerce), Stripe (payment).
👉 Key advantage: no complex installations, automatic updates, and accessibility from anywhere.

What is a traditional tool?

One traditional software (or “on-premise”) is installed directly on a computer or an internal server.
Examples: Microsoft Office (old license version), Sage, Photoshop CS6 off cloud.
👉 Key advantage: total control over the tool and data, but heavier technical management.

The benefits of SaaS

• 🌍 Accessibility : usable everywhere, on all devices.
• 💸 Reduced cost at the start : no heavy investment, simple subscription.
• 🔄 Automatic updates : no technical maintenance.
• ⚡ Scalability : possibility to add functionalities or users on request.
• 🔗 Integrations : easy connection with other tools via API, Zapier, Make, etc.

The benefits of traditional tools

• 🔒 Data control : everything is stored locally, less dependent on a third party.
• 💻 Offline operation : you don't need the Internet to use the software.
• 📦 Single payment : a permanent purchase instead of a recurring subscription (but updates are often chargeable).
• 🔧 Advanced customization : some software allows for deeper configuration than a SaaS version.

The limits you need to know

SaaS

• Dependence on an Internet connection,
• Risk of “subscription fatigue” (too many cumulative subscriptions),
• External data hosting (RGPD to be checked).

Traditional tool

• High initial cost,
• Manual or expensive updates,
• Difficulty collaborating remotely,
• Risk of rapid obsolescence.

SaaS vs traditional tool: which choice in 2025?

• 👉 For a self-employed person or a small business : SaaS is generally the best choice (flexible, economical, easy to integrate).
• 👉 For a company sensitive to security or without reliable access to the Internet : traditional software can remain relevant.
• 👉 The winning mix : use a SaaS database for daily management (CRM, billing, communication) and some software installed for specific needs (graphic creation, CAD, video editing).
