It gets the answer itself
A line comes in above the PO price. The clerk asks the buyer who agreed it, records their reply on the invoice and sends it on for approval.
AppZen’s agents read invoices in any format or language, match each line to the PO and receipt, catch duplicates and post to your ERP.
Clerked’s AI clerks do that too, then take each exception to whoever can answer it and update the invoice.

2Reason
Freight shows up that the PO never allowed for. The clerk drafts the vendor email quoting the PO line from your ERP, and you read it and send it.
3Reason
An invoice comes in far above what that vendor usually bills. The clerk sends the question to whoever owns it, and they answer from email, Slack, Teams or their phone, with no login.
4Reason
Before go-live, the clerks read your invoice history and keep what they learn in plain English, like: this vendor bills freight on a separate invoice. Your team can edit or delete any of them.
