Can this memo be reimbursed if it is not stamped?

Excuse me, do you want to ask "can the accommodation memo be reimbursed without stamping?" The notice of accommodation cannot be reimbursed.

Most units require that the total amount of the water bill (consumption detailed list) be consistent with the total amount of the invoice, and the invoice seal should also be consistent. You can't print the consumption memo yourself. It must be issued by the hotel, and it must be the seal certificate of the hotel where you live. Some companies have strict reimbursement standards, and the memo provided by the reimbursement person will be required to be stamped with the hotel seal. In this case, the front desk staff will generally stamp the invoice seal on the memo together.
