Packing Slip and Receiving Automation for Epicor Prophet 21 (P21)
Packing slip automation for Prophet 21 reads the supplier's packing slip and compares it with the open P21 purchase order before the goods are put away. An AI vision agentic system reads any layout, pairs each line with its PO line, and flags short and over shipments for the receiving team.
What Is Read From a Packing Slip
A packing slip says what the supplier put in the shipment. ESS Fusion AI reads it with an AI vision agentic system, whatever the supplier's layout and whether it arrives as a PDF, a scan from the dock or a photo of the paper copy.
- Supplier, purchase order number and shipment or packing slip number
- Ship date, carrier and tracking reference where shown
- Every line: item, description, quantity shipped and unit of measure
- Back-ordered quantities, when the supplier prints them
Telling a Packing Slip From an Invoice
Suppliers send packing slips, invoices and order confirmations to the same inbox, and they often look alike. Each incoming document is classified first, then routed to the pipeline for its type. A packing slip, a shipping document with quantities and no prices, goes to the packing slip pipeline; an invoice goes to accounts payable.
A scan that holds several documents is split by page, so a packing slip stapled to an invoice is processed as two documents.
Comparing the Packing Slip With the Open P21 Purchase Order
The packing slip is matched to the open purchase order in Prophet 21 by PO number and supplier, and each line is paired with its PO line by item. Quantities are compared after units of measure are reconciled, under tolerances you set.
- Short shipment: less was shipped than the open quantity on the PO line
- Over shipment: more was shipped than was ordered
- Unexpected item: a line on the packing slip that is not on the purchase order
- Not shipped: PO lines the packing slip does not mention, shown for information
From Verified Packing Slip to Receipt in Prophet 21
A packing slip that agrees with the purchase order can go straight through. One with differences goes to the receiving team, who see the supplier's document beside the P21 purchase order with each difference shown, and can correct, approve or reject.
Recording the receipt in Prophet 21 is configured around your receiving process. ESS's Prophet 21 API layer includes the endpoints receiving needs, so the pipeline can be set up the way your warehouse works: post the receipt automatically once a packing slip is verified, post it after your receiving team confirms the count, or pass verified data to your team to receive in P21 as they do today. ESS configures the option that fits, as part of your rollout.
Why Receiving Matters to Accounts Payable
An invoice can only be vouchered against goods that have been received. When receipts are recorded promptly and accurately, fewer invoices wait, and the three-way match has reliable quantities to work with. Packing slip automation and AP automation run on the same platform, so the receiving side and the invoice side use the same purchase order data.
