Inventory Planner by Sage

A very clever app that has clearly been put together with a lot of thought by some smart people. I haven't been using it long, so I have a feeling 'full-blown wow' will happen in future, but I keep finding things that make sense, and make my life a lot easier. I love the way when I place an order, it tells me how much I still have to order before I get to that supplier's minimum order, for example. Apart from the very clever forecasting (takes into account out of stock days when looking at sales performance - yay), it's this clever touches that save time and make working a bit more of a pleasure.
