From what you said, it should be that the company is not big. The boss asked you to sign for reimbursement. This is actually not in line with the provisions of the financial system. After a long time and a large amount, some problems may appear in the future, such as unclear responsibilities. If someone wants to mess with you, it's easy to get caught up in it.

So it is not recommended that you continue to sign others' names.

Suggestions for improvement:

1. Let the person who actually reimburses sign each foreign document. In this way, we can at least find out who these files belong to in the future.

2. Write "on behalf of * * *" when signing the reimbursement office.

3. Improve the company's financial reimbursement system.

4. Refuse to sign.
