Nothing can be sold until it is a product. A parent with sizes or colors is not itself sold. See Variants.
Add a product
- Open Products, then add a product.
- Enter Name, SKU, and Barcode. The barcode is what the counter scans.
- Enter Cost and Price.
- Enter Stock Quantity for what is on the shelf today.
- Set Minimum Stock Level. At or below this number the product is low stock. See Low stock.
- Set Unit of Measure: pieces, box, kg, gram, liter, and the other units in the list.
- Choose a Category, Status (active products sell; inactive ones do not), and Primary Vendor if you buy it from one supplier.
- Add an image if you want it on the product list. Save.

A sale reduces Stock Quantity immediately, including an offline sale on that device.
