What kind of workaround is this? This is the laziest response that you could have possible given. "We don't have a report to show you the average amount of days it takes for your customers to pay you. But, did you know that you can export a report to Excel?" How does that help? At least tell us which report to run and how to customize it so that we get the information we are looking for, since your dumpster fire of a product doesn't actually provide a streamlined method of managing customer's accounts.
