A purchase order (PO) is the document you send a supplier to order goods or services at agreed prices. It records your intent to buy before the bill arrives.
When the supplier delivers and invoices you, you record a vendor bill. This is what you owe — your payable.
Tracking POs against bills shows how much of an order has actually been billed and how much is still outstanding, so you're never surprised by a late invoice.
Recording payments made against bills shows what's cleared and what's still due, helping you plan cash and avoid missed or double payments.
A vendor statement summarises bills and payments for each supplier, and vendor aging groups what you owe by how overdue it is — the payables mirror of customer statements.
WasliPay links POs to vendor bills to payments made, and builds vendor statements and aging so you always know what you owe and to whom.
