A client’s page shows two things tied to trust: whether they are a verified wholesale buyer, and their research-use agreement.

  1. Open the client and find "Wholesale buyer".
  2. Click "Verify this buyer".
  3. Enter the business or institution name, and a license number or EIN if you have one.
  4. Note what you checked.
  5. Click "Mark verified".

A verified buyer shows "Verified wholesale buyer" on their page. Remove it any time with "Remove verification". Under "Research-use agreement", Purity lists every version they have accepted and when; it says "Not accepted yet" if they have not.
