Do I need to write out ten invoices for staying in a hotel for ten days?

Yes, if not, you can have one or an invoice.

The hotel is a normal company operation mode, and everyone should pay taxes normally. Generally, people who travel and stay in hotels also need to issue invoices or receipts to be reimbursed. Therefore, the hotel is obliged to provide these accommodation certificates for its guests. If the hotel refuses to issue an invoice receipt, it is illegal and can be handled by the police.
