Trade with LMC – Fast, Easy, Scalable EDI Integration

LMC 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. LMC 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 LMC's accounts payable validation rules.

Most suppliers are fully connected and processing live LMC EDI transactions within 3–5 business days. Stacksync's no-code setup means you don't need developers or EDI consultants — configure your field mappings through our visual interface, run a test cycle, and go live.

Stacksync prevents LMC 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 LMC-specific formatting requirements like date formats, decimal precision, and required qualifier codes. This preemptive validation eliminates the most common causes of LMC invoice chargebacks.

No. Stacksync handles the entire EDI transport layer. We connect directly to LMC's trading partner network through our certified connections. You don't need to manage a separate VAN subscription, AS2 certificates, or SFTP configurations.

Most LMC 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. LMC 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 LMC's deadlines.

Stacksync improves compliance scores by eliminating manual processing delays. Purchase Orders sync to your system in real time, ASNs are generated automatically when you ship, and invoices are validated with three-way matching before submission. Real-time monitoring alerts you to issues before they become chargebacks.

Stacksync supports all EDI document types required by LMC — including Purchase Orders (850), Invoices (810), ASNs (856), PO Acknowledgments (855), and more. Our platform handles the full lifecycle from order to payment automatically.

The most common causes of LMC 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 LMC'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.
