Is it permissible to use the company's credit card within the scope of work, given that there is a fine imposed on the company if payment is not made on time?

There is no harm in using the credit card issued by the employer for work-related tasks, if there is a need for it and it has become a widespread practice, in accordance with the rule, "When a matter becomes difficult, it expands," while limiting its use strictly to the area of need.
