What is PO Flip?
Definition
PO Flip is a procurement and accounts payable process in which a supplier converts an existing Purchase Order (PO) directly into an invoice. Instead of manually creating a new invoice document, the supplier uses the purchase order information as the foundation for generating the invoice submitted to the buyer.
This approach ensures invoice data matches the original purchase order details, improving accuracy and consistency in invoice processing. It also simplifies collaboration between buyers and suppliers by reducing discrepancies in pricing, quantities, and item descriptions.
PO Flip is commonly used in electronic procurement environments where suppliers receive purchase orders through digital supplier portals or procurement platforms.
How the PO Flip Process Works
The PO Flip process begins when a supplier receives a purchase order from the buyer. Instead of preparing a new invoice from scratch, the supplier selects the purchase order and converts it into an invoice using the existing order data.
Key information such as item details, pricing, delivery quantities, and tax information are automatically transferred from the purchase order into the invoice. This reduces the likelihood of data entry errors and improves efficiency in supplier billing operations.
Once generated, the invoice is submitted to the buyer’s accounts payable department for verification and approval.
Role in Accounts Payable and Procurement
PO Flip plays an important role in improving coordination between procurement and accounts payable teams. Because the invoice originates from the purchase order, finance teams can easily verify transactions against procurement records.
During invoice verification, finance teams compare the flipped invoice with the purchase order and goods receipt information. This supports financial control mechanisms such as three-way matching and ensures that invoices align with authorized procurement transactions.
By aligning invoices with purchase order records, organizations maintain stronger financial governance and more accurate supplier payment processing.
Key Elements of a PO Flip Invoice
When a purchase order is converted into an invoice, several important elements from the procurement record are included automatically. These elements ensure the invoice reflects the authorized transaction details.
Purchase order reference: Links the invoice directly to the original procurement transaction.
Item descriptions: Details of goods or services provided.
Quantity and pricing: Data pulled from the purchase order.
Delivery confirmation: Information related to shipment or service completion.
Tax and payment terms: Financial conditions agreed upon in the purchase order.
These elements allow finance teams to validate invoices quickly and accurately.
Example Scenario
A retail company issues a purchase order to a supplier for 500 units of packaging materials at $2.50 per unit. After delivering the materials, the supplier accesses the buyer’s supplier portal and selects the existing purchase order.
Using the PO Flip feature, the supplier converts the purchase order into an invoice. The system automatically populates the invoice with the purchase order number, item description, quantity, and unit price.
The supplier submits the invoice, and the buyer’s accounts payable team verifies it against the purchase order and delivery receipt using three-way matching. Once validated, the invoice proceeds to payment approvals and payment processing.
This streamlined process ensures accurate billing and faster invoice verification.
