Track stock for a product

1. Make sure the item is a product (not a service) in Products & services.
2. Go to Inventory → Stock on hand and click Track a product.
3. Pick the product and enter the quantity on hand today, the cost per unit and, optionally, a reorder point, reorder quantity and barcode.
4. Click Start tracking.

From then on:

• approved bills for the product add stock at what you paid,
• approved invoices take stock out and record the cost of goods sold at average cost,
• credit notes and vendor credits put stock back or take it out,
• voiding any of these undoes its stock change.

Products at or below their reorder point show a red Reorder tag, and the bell counts them.
