Even if we dont have changes in coins. We dont have to bother if we have paytm We can get the accurate change through paytm payment. If we have a bill of 75.57. We will get the remaining paisas. Basically its a smaller amount. But if we saves money likes this, after a long time. It will be a big savings. If we pay by liquid cash the merchant or vendor round off the amount and gives us the remaining money.
