Before a sample moves forward, clarify what the sample is meant to validate. Is it finish? Fit? Construction method? Packaging feel? Brand color? The more explicit the purpose, the more useful the round becomes.
That is another reason the inquiry form matters: it gives buyers a place to state intent before files and physical review start moving.
When both sides understand what the sample round is meant to prove, the feedback loop gets dramatically shorter. Instead of three rounds of revision, most projects can reach approval in one or two.
