Plants Stop Paying Invoices That Don't Match What the Dock Received
What it takes off your plate
The AgentWorks Purchase Order Agent is why a plant can stop paying invoices that don't match what the dock received. It takes the paperwork side of purchasing off your buyers: turning approved requisitions into POs, chasing supplier acknowledgments, and matching every invoice to its PO and receipt. Your buyers keep the time for suppliers, for the production team, and for the customers whose orders depend on the parts.
Here is the work today. A buyer spends half the day keying POs from requisitions, sending emails to confirm the supplier received them, and sitting with accounts payable matching invoices to receiving slips. When a rush comes in, the PO goes out without approval to keep a line running, and the compliance problem shows up later. The open PO report lives in a spreadsheet that never matches the ERP, so nobody is sure what is really on order.
The cost is a buyer with no time to source, and invoices paid for quantities or prices nobody checked.
What the Purchase Order Agent does, step by step
The work starts with the conversations with suppliers, because that is where a buyer's day disappears.
- Converts the requisition. When a requisition is approved in SAP, Oracle or your ERP, the Purchase Order Agent creates the PO with the approved supplier, part, quantity, price and need date. A requisition without approval does not become a PO; the agent routes it to the approver instead.
- Sends the PO. It emails the PO to the supplier contact on file and asks for an acknowledgment with a confirmed ship date.
- Chases the acknowledgment. If no acknowledgment arrives, it follows up by email. If the confirmed date differs from the need date, or the price differs from the PO, it flags the buyer.
- Answers supplier questions. When a supplier replies asking about a drawing revision, a delivery address or a quantity, it answers from the PO and the item record, or passes the question to the buyer when a decision is needed.
- Matches the invoice. When the invoice arrives, it matches it to the PO and the receipt: quantity received, quantity invoiced, and price.
- Flags only the exceptions. Matched invoices move to accounts payable for payment. Invoices that do not match go to the buyer with the difference spelled out: short shipment, price variance, or no receipt on record.
- Keeps the open PO list current. It updates the PO status in the ERP as acknowledgments, receipts and invoices post, so the open PO report is the ERP, not a spreadsheet.

Where the work is recorded
An agent that cannot record its results is a chatbot. The Purchase Order Agent writes every step where your team already looks.
On the supplier's contact record in your CRM, the buyer sees every PO sent, every acknowledgment, every follow-up and every question answered, in order. When the buyer calls the supplier, the history is on the screen. On the customer accounts whose orders depend on a late or short shipment, customer service sees a note, so the next call from that customer gets a real answer.
In the ERP, each PO carries its acknowledgment, confirmed date, receipt and match status. The next morning your purchasing manager opens one list: POs created overnight, acknowledgments still outstanding, and the invoice exceptions waiting for a buyer.
What your people do instead
Your buyers stop keying POs and chasing emails and do the work only a person should do: sourcing a hard-to-find part, negotiating price with a supplier whose invoices keep coming in high, and working with the production scheduler when a shipment slips.
Your accounts payable clerk handles the exceptions the agent flags, not every invoice. Your customer service reps stay with the customer on the line, with dates that rest on acknowledged POs instead of guesses.
The Purchase Order Agent keeps the supplier emails and the records moving. Your people keep the relationships and make the decisions.
