Stock Movements

Stock Movements track all changes to ingredient quantities. You can create manual stock entries with these types:

• Stock In - Add stock (e.g., received from supplier)
• Stock Out - Remove stock (e.g., wasted or used)
• Adjustment - Correct stock count (positive or negative)
• Damage - Record damaged/unsellable stock

Each movement records: ingredient, type, quantity, unit price, total amount, movement date, remark, and reference. The system automatically updates the ingredient's stock quantity when a movement is created, updated, or deleted.

Auto Stock Impact:

• Purchase - When you create a purchase, the system auto-creates stock_in movements for each purchased ingredient
• Purchase Update - Old stock movements are reversed, new ones are created
• Purchase Delete - Related stock movements are reversed
• Sale - When you create a sale, the system finds the product's recipe and auto-creates stock_out movements for each ingredient (quantity * sale quantity)
• Sale Update/Delete - Same reverse-and-reapply logic
