Questions suppliers ask
Is naming an accreditation enough?
No. Buyers need the accreditation body, certificate status and exact scope that covers the requested activity.
What should an enquiry include?
Include the product, material, asset or site, required standard, sample count or location, deliverable and deadline.
Should sample reports be public?
A redacted example can help buyers understand the format. Sensitive methods, customer data and results should remain controlled.
Check which documents and standards your buyer needs; requirements vary by market, customer and contract.
