This section holds a bit of complicated information. None of these fields are mandatory. If you do not need to add stock quantity and your is just a simple product, then you can totally skip this section.
But if you are creating a downloadable product or selling a dress or t-shirt, which has multiple sizes, then you should read this section carefully.
What is SKU?
SKU stands for Stock Keeping Unit. It should be a unique set of characters which will not match to any other product.
Enable Product Stock Management
Let’s say you have 10 pieces of the product and you don’t want to receive after orders are placed for 10 units. If you enable stock management and enter 10 in the quantity field, then after 10 units are ordered, this product will show a message that all the quantities are sold and there is no stock.
Pre-Order campaigns can be easily coordinated with your admin. Please reach out!
But, you might want to take some pre-orders before your next batch comes up. So you can Allow Back Order to let the customers place orders even if the product is out of stock.
