Why are separate purchase orders sent when suppliers have a contract with the Home Office?
Many contracts awarded by the Home Office are under “Framework Agreements” where the terms and conditions, prices, and range of items are specified but not the quantities or dates required. Under these Framework Agreements separate purchase orders have to be raised for each individual requirement to specify what is required and when. For other areas such as capital building works a separate contract is agreed between the two parties and a purchase order is then issued referring to the contract; this acts as a mechanism for the invoice to be paid.
