Can Ctrip issue invoices for tickets purchased?

Yes. Contact Ctrip customer service within 15 days to provide an electronic invoice for the tickets. The invoice is automatically generated by the scenic spot ticketing system and cannot be applied after it expires. Invoices refer to business vouchers issued and collected by all units and individuals when purchasing and selling goods, providing or receiving services, and engaging in other business activities. They are the original basis for accounting and an important basis for law enforcement inspections by auditing agencies and tax authorities.
