Set the pass conditions
Write down your must-haves for product acceptance, sales channels, dispatch, and support. Separate these from preferences. Remove providers that cannot confirm a critical requirement before comparing softer benefits.
Use one test pack
Send each candidate the same order sample and exception scenario. Record the response, assumptions, and unresolved questions. Score only what you can support; a missing answer is a gap to investigate, not an automatic pass.
Build a brief someone else can use
Write a one-page description of the products, order patterns, channels, destinations, and timing the provider would need to support. Attach a representative order file and list the questions that would rule a candidate out. Keep your must-haves separate from preferences. If a team member could not use the brief to explain what you need, simplify it before sending it to providers.
Define a test before recording a score
Write the expected result, the sample, and the evidence you will accept. Keep a failed requirement separate from an unanswered question. Use the same test across providers where their proposed scopes are comparable. If the test changes, record why; otherwise an improved score may reflect an easier question rather than a better fit.
Use this question in your next meeting:
Which requirements are mandatory, and which can change if the tradeoff is worthwhile?
