Ultimate X12 810 Invoice

Ultimate EDI 810 Invoices must include the invoice number and date in the BIG segment, the original PO reference number, line-item detail with UPCs, quantities shipped, and unit prices in the IT1 segments, plus the total monetary value in TDS. Ultimate requires exact alignment between the 810 Invoice, the original 850 Purchase Order, and the 856 ASN — this three-way match prevents deductions and chargebacks. Stacksync cross-validates all three documents automatically before transmitting the 810 to ensure every field matches Ultimate's accounts payable validation rules.

Stacksync prevents Ultimate 810 rejections through automated three-way matching. Before generating an invoice, Stacksync compares line-item quantities and pricing against the original 850 Purchase Order and the 856 ASN. Discrepancies in UPCs, unit prices, quantities, or allowance amounts are flagged before the 810 is transmitted, giving your team a chance to correct errors. The platform also validates Ultimate-specific formatting requirements like date formats, decimal precision, and required qualifier codes. This preemptive validation eliminates the most common causes of Ultimate invoice chargebacks.

Most Ultimate compliance programs require the EDI 810 Invoice to be sent after the 856 ASN but within a specific window — typically 24 to 72 hours after shipment. Invoicing too early (before the ASN) or too late (beyond the allowed window) can trigger compliance penalties or payment delays. Ultimate may also require that invoice dates match or follow the ship date on the corresponding 856. Stacksync automates this timing by generating the 810 automatically after the 856 is confirmed, ensuring correct sequencing and compliance with Ultimate's deadlines.

The most common causes of Ultimate 810 chargebacks include price discrepancies between the invoice and the PO, quantity mismatches between the invoice and the ASN, missing or incorrect allowance and charge amounts in the SAC segment, and wrong UPC or item identification codes. Late invoicing beyond Ultimate's deadline also triggers deductions. Stacksync reduces these errors by automatically populating 810 fields from the matched 850 PO and 856 ASN data, ensuring consistency across all three documents and tracking deduction trends for resolution.

Yes. Stacksync supports the SAC (Service, Promotion, Allowance, or Charge) and TXI (Tax Information) segments used in Ultimate 810 Invoices. The platform can apply Ultimate-specific allowance schedules, cooperative advertising deductions, and volume rebates automatically based on the terms in the original PO. Tax calculations are handled according to the ship-to jurisdiction. Stacksync maps these calculations from your billing system's output to the correct EDI segment codes and qualifiers, ensuring Ultimate receives properly formatted financial data.
