You can apply for meal reimbursements with the reward form - more information about the feature here: https://help.bezala.com/en/articles/110978-reward-feature-in-bezala
If your company does not yet have rewards in use, you can activate the feature from the "Expense forms" tab in the company settings. Remember to also set the account for reward reimbursements, for example 2940.
A separate reward type must be created for meal reimbursements in your company's Bezala. You can add reward types from the "Reward Types" page in the web version. The correct income type is "Meal allowance (303)."
