Use manual waste if a product has spoiled, its shelf life has expired, or it was used for dish testing or employee meals.
How to add a stock deduction in the management console
- Open Inventory → Stock deductions in the management console.
- Click Add.
- Specify the waste date and time.
- Select the storage location from which you want to deduct the products.
- In the Reason field, select the required reason from the list. If the required reason is not available, click Add and create it directly in the waste form.
- If needed, add a comment to provide more details about the reason for the waste.
For example, the reason is «Recipe development» and the comment is «Summer menu preparation». - Add products, ingredients, dishes, preparations, or dish modifiers to the waste and specify their quantity.
- Click Save.

The waste will appear in the waste list with the calculated amount and selected reason.
💡 If no ordering units are configured in your account, the Ordering unit column in the waste form will be hidden automatically.
Navigating the waste form using the keyboard
Use the keyboard when filling out the waste form:
- Tab — move to the next cell;
- Shift + Tab — return to the previous cell;
- Enter — activate a cell for entering or editing data.
How the waste amount is calculated
The waste amount is the product of the quantity of the wasted product and its current food cost. For example, if you waste 2 kg of a product with a food cost of UAH 100 per kg, the waste amount will be UAH 200.
Poster calculates cost using the weighted average method.
Can I create waste for a past date?
Yes. To create waste for a past date, specify a date and time within the open inventory period — that is, a date after the last inventory check for this storage.
You cannot select a date from a closed inventory period. If you try to save such waste, Poster will display the error message: “Check the entered values and try again.”
Only the ingredients that were included in the recipe of the dish or preparation on the selected waste date will be deducted.
Limitations
- Manual waste does not replace automatic ingredient deduction during a sale — these are separate processes.
- You cannot select a waste date from a closed inventory period.
To find a specific waste record, filter the list by storage, category, or reason, or customize the table columns, use search, filters, and list settings.
