Change orders cannot be processed in the eMarketplace. Change orders can be processed in SFS if the purchase order needs to be revised. Please note that because purchase orders will be electronically dispatched to the supplier, there will only be a short window of time to amend a purchase order before it is received and acted on. If a change order is required when the invoice is received or when P-Card purchases are reconciled, then the change order will need to be requested of the Business Services Center or processed by the Agency. If the purchase order has already been dispatched to the vendor, then you should contact the supplier directly about changing the order.
