Watchouts

No compliance/security posture listed yet — request SSO, SOC 2, and data-handling specifics if your buyer process requires them.
Deployment model isn't on file — clarify cloud vs self-hosted vs hybrid before integration planning.
Free/freemium tiers often hide rate limits, data-retention defaults, and seat caps — read the limits before scaling.
