I am not qualified to report to a third party. I can collect money and issue an invoice for consulting fees. You don't need qualification to invoice consulting service fees, as long as the business is true. When business occurs, invoices outside the business scope can also be issued. You don't have to sign a contract, you have to pay stamp duty. Therefore, I am not qualified to report to a third party, and I can collect money and issue an invoice for consulting fees.
