Request SOC 1 Type II and SOC 2 Type II reports, ISO 27001 certification, and privacy assessments demonstrating GDPR and regional compliance. Review scope, exceptions, and remediation timelines. Confirm change management, access controls, and vendor oversight. Ask about secure software development practices and periodic penetration tests. Strong governance includes segregation of duties, continuous monitoring, and executive review. Evidence should be recent, comprehensive, and understandable by security and finance without translation or evasive explanations that undermine confidence.

Support quality defines day-to-day satisfaction. Compare named account managers versus pooled queues, and hours that match your payroll calendar. Measure first-response and resolution times by severity. Ask for escalation paths, holiday coverage, and continuity plans. Evaluate knowledge bases, training portals, and community forums. Run a trial ticket with realistic complexity to assess clarity and empathy. Great support feels like a partner who anticipates deadlines, documents fixes, and teaches you to avoid the same issue twice.

Roadmaps reveal priorities; funding stability enables delivery. Ask how features are prioritized, how often releases ship, and what percentage addresses reliability versus innovation. Check leadership turnover, customer concentration risk, and cash runway. Seek transparency on sunset policies and backward compatibility. Review recent roadmap promises and actual outcomes. Favor vendors who invite feedback, share usage metrics, and adjust plans visibly. Healthy partners plan for longevity, invest in foundations, and communicate clearly when trade-offs are required for resilience.

Create categories with explicit weights, then define observable proof for each. Replace vague labels with testable statements: available prebuilt integration, audit report date, p95 processing time, or per-employee cost ceilings. Ensure two evaluators score independently to reduce bias. Publish results with comments and links to artifacts. Re-score only when new evidence appears. This discipline shortens meetings, clarifies trade-offs, and helps executives sign with confidence, protected by a transparent, auditable decision record everyone can revisit.

Scope a two-week POC around your hardest realities: complex deductions, multi-state taxes, or seasonal surges. Provide anonymized but authentic data. Define success metrics, sample size, and must-have integrations. Require vendor-led configuration with your team watching and learning. Measure support responsiveness, documentation quality, and stability under load. Wrap with a retrospective detailing gaps, risks, and implementation estimates. A disciplined POC reveals fit faster than slideware and builds trust before you commit budget and organizational energy.
