The purpose of the inventory manager is to manage all of your stock. You can add existing stock, carry out stock checks, add wastage and get an overview of expected stock levels.
Once you have added inventory here, you can then add the inventory items as ingredients to recipes which, once applied to a product will deduct quantities from your stock levels automatically upon a sale.
In this example, we have an Inventory Item of Sirloin Steak, and we are delivered them in a Batch of 8 steaks, each of which is 400 grams. In this delivery we have only recieved one batch, at a price of 33.99 from the supplier Brakes.
Once this process has been repeated to create all of the Inventory Items we can now create the Recipe & Ingredients.
