Plum Cuts AP Processing Time by 90% with Agentic Automation

Understanding the Problem

Plum is a consumer goods company in Mumbai running its operations on SAP. Every month its accounts payable team faced the same backlog. Invoices arrived from six separate vendor portals, GRNs were posted by hand, and any mismatch between the invoice, the purchase order, and the goods actually received surfaced only after payment had already gone out. By the time a wrong payment was spotted, the money had moved, and recovering it meant a slow round of vendor follow-ups.

The Agent

We built an agent that owns the full invoice-to-GRN flow inside Plum's own SAP environment. It pulls each invoice from the vendor portals and inbox, reads and extracts the line items, and runs a three-way match against the purchase order and the goods received.

Where everything lines up, the agent posts the GRN to SAP on its own. Where something is off, it holds the document, explains the discrepancy, and passes it to the team for a one-click approve or reject. Every action is logged and auditable, and no data leaves Plum's systems.

Outcome

The AP team no longer spends month-end clearing a backlog. The agent handles over a hundred invoices a day with zero manual entry on clean documents, and it catches mismatches before payment goes out, so wrong payments stop leaving the building in the first place. Work that used to take a full morning now takes a fifteen-minute review of whatever the agent flagged.

"Monday mornings were just for clearing the invoice backlog. Now I check what the agent flagged and that takes 15 minutes." Rohit, Operations Manager, Plum
