While Legiit doesn't automatically generate a formal invoice/.pdf you do have some options. Your best option is probably to ask the individual sellers to give you a formal invoice so they can accurately describe the service you purchased including your company tax ID. You can also save the email you get when you make a purchase which has all the transaction details including the order number and what your purchased and convert that to a .pdf. You can also visit https://legiit.com/buyer/transactions for your transaction history, though that may not have enough details for your needs.
