The process begins with verification rather than with a product key.
Step 1: Identify the exact Office product
Provide the complete edition name, version and platform where known.
Step 2: Prepare ownership evidence
Collect invoices, licensing records, purchase channel details and original organization information.
Step 3: Record current status
Explain whether the license is active, unused, tied to a device or account, or part of a company migration.
Step 4: Submit the portfolio summary
Send quantity, documentation summary and business context through LINE without publishing secret keys.
Step 5: Complete eligibility review before valuation
Only software assets with verifiable lawful ownership and appropriate transfer rights should proceed to a commercial discussion.
