purchase orders and invoices are essential business documents that support smooth purchasing and billing workflows. A purchase order (PO) captures a buyer’s request for goods or services, outlining quantity, pricing, and delivery terms before the transaction. An invoice is issued by the seller after delivery, requesting payment and including pricing, taxes, and due dates. Managing purchase orders and invoices digitally ensures accuracy, accountability, and faster payment cycles.
