This friend, the formal catering invoice with special financial seal can be used as reimbursement voucher. However, if the expenses reimbursed by you do not meet the requirements for reimbursement of "entertainment expenses" of our company (such as private expense bulletin), or your company's financial accounting system has special provisions on "invoice stamp", etc. This belongs to the internal management system of the company, as long as it is the same for everyone. Finally, if it is not for the above reasons, it will neither affect the tax payment nor violate the company's reimbursement management system, then it may be that the financial personnel misunderstood the scope of the current invoice, and you can explain it clearly to the financial personnel. I believe an honest and selfless accountant will make a reasonable explanation.
