Software as a Service Explained
SaaS (Software as a Service) is a software delivery model where the application runs on the vendor’s servers and users access it through a web browser. You don’t install anything, manage servers, or handle updates — the vendor does everything. You pay a recurring subscription fee, typically per-user per-month.

Salesforce, HubSpot, Zoho, Pipedrive, and Monday CRM are all SaaS products. You visit their website, log in, and use the CRM. Your data lives on their cloud infrastructure.
SaaS CRM: Vendor hosts, manages, and updates the software. You access via browser. Recurring per-user fees. Limited customization within vendor’s framework. Your data on their servers.
Self-Hosted CRM: You host the software on your own infrastructure (VPS, cloud, or on-premise). One-time setup, no recurring license fees. Unlimited customization. Your data on your servers.
SuiteCRM is a self-hosted open-source CRM — the opposite of SaaS. Zero licensing fees, complete data ownership, and unlimited customization.
Fast to start. Sign up and begin using the CRM in minutes. No server setup, no installation, no IT involvement. Automatic updates. The vendor pushes updates — you always have the latest version. Managed infrastructure. Uptime, security patches, backups, and scaling are the vendor’s responsibility. Low upfront cost. No server purchase or setup investment. Costs are spread as monthly subscription.
Recurring costs escalate. Per-user fees grow linearly with team size. A 50-user team on Salesforce Enterprise pays $198,000/year — every year, forever. See our cost analysis.
Limited customization. You can configure within the vendor’s framework, but you can’t modify the underlying platform. When the CRM doesn’t do something you need, you’re stuck — or paying for expensive add-ons.
Vendor lock-in. Your data format, custom code, integrations, and workflows are tied to the vendor’s platform. Switching is painful and expensive.
No data sovereignty. Your customer data lives on the vendor’s servers. You can’t control where it’s stored geographically, who at the vendor company can access it, or how it’s handled internally. This creates compliance challenges for HIPAA and GDPR.
Price increases. SaaS vendors raise prices regularly. You accept or migrate — and migrating away is deliberately difficult (see vendor lock-in).
