Accounts receivable (A/R) at Microsoft is massive. The company's Global Treasury & Financial Services (GTFS) group is responsible for A/R for almost every business unit throughout the global organization. That means the team handles receivables on millions of invoices, for thousands of customers, each month—and those numbers continue to grow. In fact, as Microsoft Azure and other innovative lines of business have taken off over the past five years, the company's A/R volume has nearly doubled, and it shows no signs of slowing down.

The GTFS group outsources collections for all those receivables to Accenture. A couple of years ago, members of the Accenture team were preparing receivables forecasts using manual processes that were not sustainable considering Microsoft's growth trajectory.
