Maintain cost of goods sold and contribution margin
This is how you enter the cost of goods sold per item or have it calculated from recipes and purchase prices in the warehouse.
The cost of goods sold is what a portion costs you to purchase, excluding VAT. The contribution margin is the net selling price minus the cost of goods sold: what you keep for staff, rent, and profit per item sold. The statistics use both in the menu matrix.
Prerequisite: You can enter new goods cost data using the Max tariff. An already entered value remains visible and editable in every tariff. Calculations based on inventory require an active inventory.
Add to the item

Enter cost of goods sold
Open the item under Menu and click Enter Cost of Goods Sold next to the price. Enter the amount in Cost of Goods Sold in €. The Contribution Margin will appear next to it; if it's negative, it will be shown in red. Click Save.
Let the calculation be done from the warehouse
If a sales item is linked to the warehouse, Servire calculates the cost of goods sold from the purchase prices: quantity per sale multiplied by purchase price/package (net) divided by the package size of the preferred supplier. Example: 0.18 kg of ground beef from a 5 kg box at €42.50 results in €1.53, to which the other ingredients of the recipe are added.
This only applies if every ingredient has a purchase price. If one is missing, the statistics use the value listed on the item. In the item dialog, instead of the contribution margin, it will then display Purchase prices in stock take precedence.

You manage purchase prices in the inventory under Suppliers. If the supplier's price increases, you adjust it there once, and all dishes containing that ingredient are recalculated.
