Give the vendor realistic employee records, approvals, exceptions, security roles, reports, and integration failures. Ask the proposed system to complete the work live instead of relying on a scripted feature tour.

Confirm which capabilities are included, which depend on another product or partner, and which roadmap statements are not contractual. Reconcile the final scope with your written requirements.
