Hi Lisa, thanks for your post.  It has baffled us for years as to why the Fortune 1000 Companies do that to us.  I'm not going to name names, but we had one company (one of the largest underwriters in the country) constantly short-pay, no-pay, late-pay on orders all the time.  We would jump through all the hoops to get them the info they wanted and it still wasn't good enough.  The funny ones were the orders that they claimed that they couldn't find in their system, even after we gave them their order number, borrower's name, address, city/state/zip.  It's not like we invented order numbers and tried to bill them for it.  But with some clients, we were use to being 6 months out with them and when you have people banging on the door for stuff that is 60 days old, well it's not hard to do the "cash-flow-math" on that.
