Changing the sale quantity for a product
To change the sale quantity of a product:
1. Navigate to the edit form for your product (How do I edit a product?)
2. Scroll down to the Additional Details section
3. In the textbox called Sale Quantity, enter in the number of items that need to be reduced from stock when a single unit of this product is ordered.
For example, if you sell a product that contains 4 bars of soap you would set the Sale Quantity to 4. Each time this product is ordered, your stock will be reduced automatically by 4.
