Problem
The Cost price field is not shown in the form.
Possible cause
The Cost price field is hidden when stock tracking is enabled on an existing product. Cost prices are instead managed via individual stock entries when stock tracking is active.
Solution
Check whether Enable stock tracking is switched on.
If you need to enter a cost price directly, you must disable stock tracking.
Be aware that disabling stock tracking permanently deletes all existing stock records.
If the problem persists, contact support and include details about:
Whether stock tracking is enabled for the product.
When the issue occurred.
