The name of the item for invoicing is usually called "catering service". When issuing invoices, according to the regulations of the state tax department, you usually have to choose the item that matches the business license and business scope for declaration. For enterprises in the catering industry, "catering service" is usually chosen as the project name for invoicing. Of course, the specific project name may vary depending on the region and tax policy. If you have specific regional and policy requirements, you can consult with your local tax agency to understand the specific project name requirements when applying for invoicing.
