The accounting system requires that whether there are exchange vouchers or not, the original vouchers (including invoices) for bookkeeping should be true and legal, and in principle, they can be reimbursed.

However, some units will make some regulations on their own, requiring exchange vouchers and so on. Otherwise, it will not be reimbursed. Therefore, if your company has such a regulation, it is not illegal for the accountant not to report it to you. .
