A Notice of Inability to Fill Order is a formal document issued by a vendor or supplier when they are unable to fulfill an order as requested by a customer. This notice typically includes the details of the order, the reasons why the order cannot be fulfilled, and potential alternate solutions or timelines for fulfilling the order. There are two primary types of Notice of Inability to Fill Order: 1. Partial Fill Notice: This type of notice is issued when the vendor or supplier is able to partially fulfill the order, but is unable to fulfill all the items requested. The Partial Fill Notice will include details of the items that can be supplied and items that cannot be supplied. 2. Fulfill Notice: This type of notice is issued when the vendor or supplier is unable to fulfill any portion of the order. The Full Fill Notice will include details about why the order cannot be fulfilled and any potential alternate solutions or timelines.
