If you are paying salary in cash and need to obtain a receipt of payment made, what does your standing order say? Such aspects must be covered under your own certified Standing Order (SO). However, if it is silent or you need a practical solution in today’s context, as revenue stamps are not available even in most cities, then display a notice on the notice board to the Labour Department. State that employees’ dues, including salary, bonus, etc., if paid in cash, require the concerned employees to acknowledge the receipt of payment with their signature or thumb impressions in the register.
