VL by eHouse | Amazon Vendor Central Connector

Selling to Amazon as a first-party vendor is a different discipline from selling on Amazon. Vendor Central runs on EDI — purchase orders, advance ship notices, invoices — and Amazon's compliance requirements are strict enough that manual processing isn't just slow, it's a chargeback risk. Every missed ASN or mismatched invoice costs real money.

The VL by ehouse Amazon Vendor Central Connector is a fully elastic, scalable EDI solution that automates the vendor relationship end to end, ensuring compliance across all EDI partners and giving businesses on Vendor Central a robust foundation for the long term.

What the connector does

• Receives Amazon purchase orders and delivers them into your ERP or order management system automatically
• Generates and transmits compliant EDI documents — order acknowledgments, advance ship notices (ASNs), invoices — on Amazon's timelines
• Keeps inventory and item data aligned between your systems and Vendor Central
• Extends the same EDI infrastructure to other retail trading partners, not just Amazon

Why does EDI compliance matter for Amazon vendors?

Amazon enforces its vendor EDI requirements with chargebacks — deductions for late ASNs, incorrect labels, invoice mismatches, and missed confirmation windows. For vendors processing meaningful volume, weak EDI discipline translates directly into margin erosion, and persistent non-compliance can affect the vendor relationship itself. Automated, integrated EDI addresses the root cause: documents are generated from actual system data (not re-keyed), transmitted within Amazon's required windows, and validated against the spec before they're sent. The VL by ehouse connector manages this as a service — including the ongoing burden of spec changes and trading-partner testing — so compliance isn't dependent on one operations person knowing the rules. And because it's built on the same platform as ehouse's other connectors, the PO-to-invoice flow that serves Amazon can serve every other big-retail EDI relationship you have, from a single integration point. For context on what that looks like in practice, see the Brome Bird Care EDI case study.
