Judging from your description, this is the special financial seal of the enterprise. The Basic Accounting Work Standard stipulates that the original vouchers obtained from other units must be stamped with the official seal of the filling unit (the official seal here refers to the seal with legal effect and special purpose, which can prove the identity and nature of the unit, including business official seal, special seal for finance, special seal for invoice and special seal for settlement, etc. ). In other words, this chapter can be a special financial seal. So your invoice can be reimbursed.

In addition, I want to correct what the manager of "one single household" said (sorry): the catering industry belongs to the service industry and generally pays business tax, so there is no problem of ordinary taxpayers and small-scale taxpayers, and VAT invoices cannot be issued.
