Your company buys promotional goods (logoed pens, notepads, tote-bags, etc.) for your sales and recruiting staff to give away to customers, prospective applicants, and at community events. The cost of these is relatively small, but your CEO has dictated that he doesn't want "all that stuff all over the office," so you can't just buy in bulk and store it for when needed. Your staff can't tell you precisely when they need materials because sales events, recruiting opportunities and community events often crop up unpredictably. Do you use a PO, a Blanket PO or Automated Purchasing to manage the buy?
