Interesting point for a gazillion $ company:

"Fab is NOT automated, everything is done manually by emailing people back and forth a LOT. (At least when I worked with them). Everything is done through numerous people. There’s a person in charge of buying, editing your listing, shipping, accounting, UPS account setup, packing slips, payouts, etc… And they will all send you emails with forms, and excel spreadsheets, and instructions. It can get complicated on your first time through."
