When you add a product to your basket, and there is zero stock currently available in your depot, or any depot, you will see a pop-up asking if you wish to add the item to Back Order or not. If you agree, the item will be added to your order, but will not be charged for until it is in stock. (If payment is made via Credit Card or before an Adjustment can be made to your completed order by your Client Liaison, the payment will be held as a credit). Once we receive a stock replenishment, you will be invoiced if you have not paid yet. Once payment has been received, your order will be shipped. Please note that Back Orders are filled first according to order date, with earlier orders getting preference.
