SaaS (software as a service)
SaaS — software as a service — is software that customers use over the internet, usually through a browser or app, and pay for by subscription. The provider hosts the software, maintains it, updates it and stores the data. Common examples include CRMs, accounting tools, helpdesks and booking systems.

Explained
For buyers
Advantages:
- Fast start, no installation or servers.
- Predictable subscription costs.
- Updates and security handled by the provider.
- Access from anywhere.
Trade-offs:
- You adapt to the product's model and roadmap.
- Costs grow with users or usage.
- Data is stored on the provider's infrastructure; check location, export and terms.
- Integration with local systems — payment providers, 1C, e-invoicing — may be limited.
For companies building SaaS
A SaaS product serves many customer organisations from one system. That requires:
- multi-tenancy: each customer's data isolated from others;
- plans, limits and billing, often with recurring payments;
- onboarding for new customers;
- reliability, security and support as core features.
