Sir. In general, when we are in the business of suppply of service, in most of the situations, we are in need of paying certain amount from our pocket and then lator on the invoice is raised to get the amount reimbursed from the principal. In this case, what could be the the SAC code? .
what i understand is that the SAC, for such reimbuesement of expenses, is of the one which is of a principal supply of service. Am i correct.
