Item History

Track the history of quantity and price changes for items, including stock-in and stock-out records.

What is Item History?

Item History logs every quantity adjustment:

  • Restock: quantity increase, such as purchasing or restocking
  • Consume: quantity decrease, such as usage or selling
  • Each adjustment records the date, quantity, price, and notes
  • A line chart visualizes quantity and price trends over time
Plain explanation

Item History works like an inventory ledger -- it records every stock-in and stock-out. For example, if you buy 5 units, log a restock of 5; if you use 2, log a consumption of 2. This gives you a clear view of how your inventory changes over time.

Tip

History is best suited for items where you need to track quantity changes, such as inventory management. Regular collectibles typically don't need the history feature.
