This control will be visible when the checkbox Product is marked by default in inventory is marked in the controls page.

The product number supplier uses for the product.

If you define cost price for the products then all queries in the sale system will show total cost price of sold products. Total cost price in queries will only be shown for invoices registered after cost price is registered on the product.

If the product number used for stock control is not the same product number as used in the sale system, you can define the stock product number here. For example you maybe have two products with different prices but it is the same product on stock. You could also define here that sale of one product should affect the stock quantity of more than one product number i.e. one product in sale is combined of more than one product in stock control. By clicking on you could fill in the stock product number/numbers.

This part of the screen is used for recording stock. All sale transactions are imported automatically to the stock system and by default they are not shown in the transaction list. You could cancel the selection of tick box Hide sales transactions to view all the transaction record here If you click on the link in the reference column the invoice is shown. Sold products in the Workdiary system are immediately imported as transactions to the stock system.
