working meals, like company banquets, should be made into expenses, so it's good to keep them for future reference. There are many ways to make cash vouchers:

First, when issuing cash vouchers, they are temporarily recognized as deferred revenue according to the full amount of vouchers, and then converted into income according to the amount of vouchers used by customers;

Second, when issuing vouchers, no accounting treatment is required. When customers use vouchers for shopping again, they can mark the amount of vouchers as a discount, and confirm the income according to the deducted amount invoice. The second method is widely used.
