B2B SaaS is a different product than B2C SaaS — in ways that matter for tooling decisions. B2B customers buy at the company level (account-based access, team seats, workspace isolation) rather than the individual level. They expect enterprise-grade features: SSO for workforce authentication, audit logs, data export, granular permissions, and the ability to add and remove team members without contacting support. Pricing is usually flat-per-account or tiered by feature set rather than per-user metered.

These requirements translate directly into technical specifications: multi-tenant data architecture (each customer company's data is isolated from every other), team and workspace management, SSO integration, and account-level billing. Building AI-powered applications into B2B SaaS is increasingly a competitive necessity — AI features are now expected, not differentiating.

This article covers seven tools — one per category — that address the specific technical requirements of B2B SaaS.

Multi-tenancy. Each customer company (tenant) should see only their own data. This is an architectural requirement, not a cosmetic one — the database design and access control logic need to enforce tenant isolation at the data level, not just the UI level.
