Why Vendor Evaluation Matters

SaaS contracts are easy to sign and hard to exit. By the time you discover a platform's hidden limits — feature paywalls, poor support, sketchy uptime, or problematic data portability — you may be 12 months into an annual contract with significant data migration pain ahead.

A structured evaluation process prevents these surprises. Here's the checklist we use.

Section 1: Security & Compliance

  • Do you maintain SOC 2 Type II certification? Can you share the report?
  • Are you ISO 27001 certified?
  • How is data encrypted at rest and in transit?
  • Where is data stored geographically? Can we specify a region?
  • How do you handle subprocessors? Who has access to our data?
  • Do you support GDPR data subject requests (access, deletion)?
  • What is your penetration testing cadence? Can we see results?
  • Do you have a bug bounty program?
  • How are employee access controls managed (MFA, SSO, least privilege)?
  • What is your incident response process? What is your breach notification SLA?

Section 2: Reliability & Performance

  • What is your historical uptime over the past 12 months?
  • Do you have a public status page? Where can we see it?
  • What are your SLA guarantees, and what remedies exist if they're missed?
  • How do you handle planned maintenance windows?
  • What is your disaster recovery plan? What is the RPO and RTO?
  • How does performance scale as our usage grows?
  • Are there usage limits (API rate limits, storage caps, user seats) that could affect us?

Section 3: Pricing & Contracts

  • What is the full pricing model — per user, per usage, flat rate?
  • What happens to pricing as we scale? Are there volume discounts?
  • What is the contract length and renewal terms?
  • Are there auto-renewal clauses? What is the opt-out notice period?
  • Are there setup, onboarding, or implementation fees?
  • What is included in each pricing tier, and what features require add-ons?
  • What is your pricing history? Have you raised prices on existing customers?
  • Are there discounts for annual prepay vs. monthly billing?

Section 4: Support & Success

  • What support tiers are available (chat, email, phone, dedicated CSM)?
  • What are the support hours? Is 24/7 support available?
  • What is the guaranteed response SLA by severity level?
  • Is there an onboarding program? What does it include?
  • What documentation, training, and self-service resources are available?
  • Is there a customer community or user group?
  • Do you assign a dedicated Customer Success Manager? At what tier?

Section 5: Product & Roadmap

  • How frequently do you release product updates?
  • How is customer feedback incorporated into the roadmap?
  • Can we view the public roadmap?
  • How do you handle feature deprecation? What is the notice period?
  • What is the history of major version migrations? Were they disruptive?
  • Do you have a beta program for early access to new features?

Section 6: Integration & Data

  • What native integrations do you offer with tools we use (listed them)?
  • Is there a public API? What authentication methods are supported?
  • What are the API rate limits?
  • What data formats does the API support (REST, GraphQL, webhooks)?
  • How do we export our data? What formats are available?
  • Is there a bulk data export option? Are there any restrictions?
  • Are there fees for data exports?

Section 7: Exit & Portability

  • What happens to our data if we cancel? How long do you retain it?
  • How long do we have to export our data after cancellation?
  • What is the process for data deletion upon request?
  • Do you provide transition assistance if we switch to a competitor?
  • What are the penalties, if any, for early contract termination?

How to Use This Checklist

For small software purchases (<$10K/year): Focus on sections 1, 3, and 7. Security, pricing clarity, and exit terms matter most for every purchase. For mid-market purchases ($10K–$100K/year): Complete all seven sections. Request formal answers in writing as part of the procurement process. For enterprise purchases (>$100K/year): Engage your legal, security, and procurement teams. Commission a formal security assessment. Negotiate SLA terms and exit clauses before signing.

Red Flags to Watch

  • Unwilling to share SOC 2 report (even under NDA)
  • Uptime SLA with only service credits, no exit rights for chronic failures
  • Auto-renewal with short opt-out window buried in contract
  • Data export only available in proprietary formats
  • Vague answers about subprocessors or data residency
  • No public status page or incident history

The Bottom Line

The best vendor relationships start with the right questions. A vendor that's confident in their product and practices will answer these questions readily. Hesitation or evasion on security, data portability, or contract terms is itself useful information — it's a signal of what the relationship will look like after you sign.
