Paying late is corporate finance 101. Or at least 201. I remember building spreadsheets in class showing the difference in paying bills on time vs net 30, 60, 90. The difference is pretty significant when dealing with large numbers.
The difference used to be significant when inflation and interest rates where in the order of 10% year over year. It's not the case anymore since they dropped to near zero, unless you really don't have the cash on hands to pay now.
