Clerked vs SAP Ariba

A vendor emails an invoice with no PO number. The clerk asks whoever buys from that vendor, then matches every line to the PO and goods receipt and shows you what changed.

An invoice is missing a tax ID or a remit-to address. The clerk drafts the request for exactly that, someone on your team sends it, and the corrected invoice is matched when it arrives.

A price above the PO goes to the buyer who agreed it, and an unusually large bill to the controller. They answer from email, Slack, Teams or their phone, with no login.

Before go-live, the clerks read your invoice history and keep memories like: forklift repairs from this vendor have no PO and code to plant maintenance. Your team can edit or delete any of them.
