Does the hotel memo need to be stamped?

Whether the hotel water bill needs to be stamped depends on the specific use scenarios and requirements.

1. In general, the hotel water bill is used to prove the consumption list during the stay, so that guests can refer to the invoice amount. In this case, hotel memos usually don't need to be stamped, because if guests need memos, they usually need to issue invoices.

2. However, some companies have strict requirements on reimbursement standards, and may require the memo provided by the reimbursement person to be stamped with the hotel seal. In this case, the front desk staff will generally stamp the invoice special seal on the memo together.

3. Under certain circumstances, if an enterprise needs to use the hotel memo as a reimbursement voucher or a government agency requires approval, the hotel memo may need to be stamped with the official seal to prove its authenticity and validity.

Therefore, whether it is necessary to stamp depends on your specific needs and usage scenarios. If you need more detailed information or professional advice, I suggest you consult relevant departments or lawyers.
