Foreign invoices are different from domestic invoices. There is no such thing as an invoice stamp. At most, there is a signature, and some people don't even have a signature. Generally, as long as the amount is clear and the content meets the reimbursement requirements, it can be recorded.
Accounting requirements must be kept in RMB, so there is a foreign currency exchange rate problem in foreign currency business accounting. Generally, the foreign currency exchange rate is determined by enterprises and units themselves, and can be set as the central bank exchange rate on a certain day of a certain year.
It can also be set as the middle price of the bank at the beginning of each month, the end of last month, the beginning of each year and the end of last year. This is all decided by myself, but once it is determined, it cannot be easily changed.
The exchange rate stipulated by the company is converted into RMB for reimbursement. If there is no clear stipulation in the company, the middle price on the day of business trip or the middle price on the day of reimbursement can generally be used as the exchange rate.
