To add a product to your list, click the 'Products' menu and then the 'Add' button. You will see an input field where you can fill in all product details. When you start typing a product name in your invoice you can select it from your list.
The 'Stock' field allows you to manage your supplies. For example: you have ten units in stock and you sell three units. When you add these sold products to your invoice the stock will change to '7'.
By using a USB or Bluetooth barcode scanner (prices vary between 70 € and 430 €) you can save the unique barcodes (numbers) as a reference.
In the description you will see the product name. After scanning the barcode, the unique barcode number of the scanned product will automatically appear in the orderline. Based on that reference Billit will suggest the correct description and you can quickly create the invoice based on the scanned products.
