Know what is on the shelf, in every warehouse and store

Keelvy keeps one stock figure per item and per location, moved by orders, purchases, production and transfers. Each movement says who made it and why, so a number that looks wrong takes a minute to trace.

Count a shelf on your phone, post the differences with a reason, and see the day each item runs out at the current pace of sales. Purchase orders start from that date, not from a hunch.
