Wonder what Apple caved on. They famously only found goldman to work with them originally because they had significant demands that bucked the industry, including setting everyone's statement dates to the exact same so that customer support collapses the same day every year.
Every _month_. And it's not just the customer service desk that's a problem. With even distribution of billing and a large customer base, outflows match inflows and you don't have to do much to manage it. With all money coming in on one day you have a huge outflow of money and then it all rushes back in.
Much easier to borrow 1 dollar for a year than 30 dollars for a month.
