Method 2: If it is inconvenient for your friend to sign the first method, please ask the company accountant to open an ordinary receipt, write down the year, month and date, write down the reason for receiving the money, write down the quantity of machinery and equipment (* * *), and write down the payment method as "currency". Paste the official invoice you received together with the above text description on the accounting voucher and let the accountant say yes. It's best to let people who know sign the instructions and invoices.
This should be no problem.
