B2B SaaS tool list
Best B2B SaaS Knowledge-Base Tools in 2026
A knowledge base is a product surface, not a dumping ground for resolved tickets. The right tool helps a customer or teammate find a current answer and makes content failure visible.
Evaluate search success, self-service resolution, article freshness, escalation quality, and ownership. Do not call a ticket deflected if the customer simply abandons search.
