Stock and warehouses
Every movement is recorded, every serial number has its history, and a reserved unit cannot be sold twice.
Move stock between warehouses with transfers (shipped, then received), see what is reserved and what is still available, and set reorder levels. People allowed to see costs also see stock value by warehouse.
Track serial numbers and the history of each serial, so you know which inverter left and when.
When the reseller accepts the quote, the stock is reserved. The goods leave the warehouse when staff record the collection; if the quote is refused or expires, the reserved stock is freed.
For products in short supply, give each reseller a fixed quantity they may order. The portal shows them only their own remaining quantity, never the warehouse total. It's a ceiling, not stock set aside: real stock stays first come, first served.
Stock quantities per warehouse load from an Excel template. A row sets the quantity a warehouse holds and records the difference as a movement, so running the same file again changes nothing.
Worth knowing
No approval step or printed exit slip for stock leaving the warehouse. Costs and valuation are in US dollars.
