This checklist provides a structured, scorable evaluation framework — so you make the decision based on evidence, not sales presentations.

Key takeaways
- Evaluate 3-5 vendors using a structured scoring framework — gut feel and sales presentations are not reliable selection criteria
- The vetting process and replacement guarantee are the two most important criteria — they determine whether you get qualified engineers and what happens when it does not work out
- Beware of hidden costs: management fees, overtime surcharges, and setup fees can increase effective rates by 15-25% above the quoted hourly rate
- Always check references — call actual clients, ask about engineer quality, and specifically ask how the vendor handled problems
- Start with a trial engagement (1 engineer, 2-4 weeks) before committing to a larger team — it is the most reliable way to evaluate a vendor
