You can apply for a night travel allowance through the reward form - more information about the feature here: Reward feature in Bezala | Bezala Help Center
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 also be created for night travel allowances in your company's Bezala. You can add reward types from the Bonus Types page in the web version. If the night travel allowance is paid according to the maximum amount set by the Tax Administration, it will not be reported to the income register. In this case, the income type for the night travel allowance should be selected as "Do not report to the Incomes Register".
