The 3 Way Match Purchase Order is a process used in business to ensure accuracy and accountability when making purchases. It is a three-step process that involves the buyer, the supplier, and the accounts payable department. The buyer initiates the process by creating a purchase order that includes the item, quantity, and price. The supplier then sends an invoice that matches the purchase order, and the accounts payable department verifies that the invoice matches the purchase order. Once all three parties have agreed that the invoice matches the purchase order, the payment is released. This process is important to ensure that the right items are being purchased at the right price and that all parties are held accountable for their actions. The 3 Way Match Purchase Order is a key component of any successful business, as it helps to ensure accuracy and accountability in the purchasing process.
