Make stock counts trustworthy before launch.

Define what the count represents

A source system may export on-hand stock, available stock or stock after reservations. Identify which number you have before putting it into a new platform. Subtracting reservations twice can hide inventory; ignoring them can oversell it.

Keep counts at the variant level. A total for the product family is not enough when each option has its own physical stock.

Reconcile a small high-risk sample

Pick a low-stock item, a popular variant and a product with open orders. Compare the physical count with reservations and the available quantity. Investigate mismatches before applying a bulk correction.

Example: 20 units are on hand and four belong to unshipped orders. If the export already says 16 available, importing 16 and then subtracting those four again produces the wrong selling quantity. Write the definition beside the import field.

• Record the timestamp and source of the count.
• Track stock changes during the migration window.
• Review damaged and non-sellable inventory separately.
• Confirm what cancellation and restocking do to availability.

Make adjustments explainable

Use reasons such as stocktake correction, damage or received inventory. Keep the person and date with the adjustment where your workflow supports it. A number that changes without context is difficult to trust later.

Before opening a new Torva store, test the inventory outcome of an order, a cancellation and a permitted restock. A correct product page does not prove every stock transition is correct.
