question

I am a seller of office supplies. Sometimes the purchasing manager of a company comes to buy and requests to issue an invoice higher than the purchase price. Is such a thing permissible?
Response

It is not permissible if issuing an invoice higher than the transaction price means that the transaction is carried out at that price and as a result is false, or causes harm to others. Otherwise, if it is against the law, it is not permissible due to caution.
