How to query whether the invoice has been reimbursed?
Normal companies will have their own reimbursement system, so they can't declare invoices repeatedly or set up their own ledgers.
Reimbursement needs to be kept in the books. You can use a special invoice to check whether it is deducted, but if you use an electronic invoice, you can't verify whether it is reimbursed. You can ask me for specific analysis.
