Setup task

What this does

A stock item (a “Sku”) is the master record for something you hold, buy, sell or build. It defines the code, unit, costing and tracking that every document then reuses.

Open Stocks

Go to Menu > Inventory > Master Data > Stocks and click Create.

The tabs

  • Stock Item. Code (the Sku), name, description, unit of measure, photo, dimensions, weight, class and category.
  • Sell & Purchase. Whether the item can be sold and bought, its prices, and vendor catalogue items.
  • Properties. The Costing Method and whether serial tracking is on.
  • Attributes. Batch, expiry and your own custom fields (see Track serial, batch and expiry).
  • Unit Conversion. Sell or buy in a different unit from the one you stock in.
  • Production. Link a Bill of Materials and production settings for items you build.

Choosing a costing method

On the Properties tab, set how the item is valued:

  • Weighted Average. Cost blends across receipts. The usual choice.
  • First-in-first-out. Oldest cost leaves first.
  • Average. A running average cost.
  • No cost tracking. For items you do not value.
Set it early. Pick the costing method before the item has movement. Changing how something is valued after it has a transaction history is disruptive.
