In Katana, it is possible to have negative stock levels for your products and materials. Even though it is allowed, we recommend avoiding the negative stock.

When you are using ingredients in manufacturing or selling items that do not exist in stock, Katana is unable to calculate the costs correctly and you will end up with incorrect Average Costs for items and incorrect profit margins for Sales Orders.

Katana gives you visual status alerts when some ingredients are not available for manufacturing or sales items available for sales orders. You should not complete a sales order or a manufacturing order when either the sales items or ingredients availability shows "Not available".
