Meal tickets can be opened at the place where you eat. Because every catering department has to pay business tax, but it can get some catering invoices every month. Now most computers are electronic invoices.

In China, the issuance of food and beverage vouchers needs to meet some conditions and corresponding legal requirements. Generally speaking, the following departments can handle catering tickets:

1. Bureau of Commerce: Some areas can contact the local bureau of commerce for consultation and application. The Commercial Bureau can provide detailed procedures and a list of required materials.

2. Tax official: Meal tickets are also called special VAT invoices. Please go to the local tax bureau to find out the specific billing requirements and procedures. You need to submit the necessary application form, identification, business license and other relevant documents to the tax bureau.

3. Catering software platforms: Some catering software platforms or third-party payment platforms can also provide the service of issuing catering vouchers. If you are using a similar platform to order food or pay, you can view and download food and beverage coupons through the corresponding functions.

Please note that you need to ensure that you meet the relevant laws, regulations and tax requirements before handling the food and beverage vouchers. Specific treatment procedures and required materials may vary according to regions and policies. It is recommended that you consult relevant local departments or institutions before handling, so as to obtain accurate information and operating instructions.
