What should I confirm before purchasing on behalf of an organization?
Ask the seller about required document information before ordering if it matters. Check whether the intended scope or number of users is covered when relevant.
What should I remove before sharing an order screenshot publicly?
Check for visible order references that could expose private purchase information. Avoid relying on a reversible annotation to protect private details.
