This transaction set communicates invoice details for grocery products from suppliers to retailers or distributors. A vendor sends the X12 880 typically in response to a purchase order or at the time of shipment to document the products delivered, quantities, pricing, and applicable charges or allowances. The G01 (Invoice Identification) segment establishes the invoice number and date, the G17 (Item Detail - Invoice) segment specifies individual line items with their product codes and quantities, and the G33 (Total Dollars Summary) segment provides the invoice total and financial summary required for payment processing.

Consider a scenario where Fresh Valley Farms ships a truckload of produce to Metropolitan Grocers. Fresh Valley Farms transmits an 880 transaction that includes invoice number FVF-98765, lists 48 cases of organic tomatoes at $12.50 per case, 24 cases of lettuce at $8.75 per case, and applies a $50 promotional allowance recorded in the G72 (Allowance or Charge) segment. The G31 (Total Invoice Quantity) shows 72 cases, and the G33 (Total Dollars Summary) calculates the net amount of $694.50 after the allowance. Metropolitan Grocers receives this 880 to reconcile against their purchase order, verify receipt, and process the vendor payment.
