eBay · InfiPlex OMS Integration
eBay Integration: one of the world's biggest buyer bases, zero extra workflow
eBay remains one of the largest buyer pools in eCommerce, and its sellers run some of the most varied catalogs anywhere — new, used, refurbished, one-offs and deep SKUs side by side. The InfiPlex™ OMS connects your eBay account so orders, inventory, and tracking run through the same automated rail as every other channel.

How it works
How the InfiPlex eBay integration works
eBay rewards sellers who ship fast and never oversell — and punishes the opposite through seller standards and search placement. InfiPlex automates exactly those two things: every new eBay order flows into the OMS within minutes, ships through your carriers, warehouse, or 3PL, and confirms tracking back to eBay instantly, while channel-wide inventory sync keeps the quantity on every listing honest as you sell across marketplaces.
What’s included
Everything the eBay integration handles for you
-
Automated Order Import
eBay orders pull into the OMS about every 15 minutes and join one queue with your Amazon, Walmart, and webstore orders.
-
Real-Time Inventory Sync
Every sale anywhere adjusts your eBay quantities instantly, with per-channel buffers — critical when the same unit is listed in multiple places.
-
Multi-Format Catalog Support
New, used, and refurbished SKUs draw on one master pool, so condition-variant listings stop being an overselling hazard.
-
Shipping & Tracking Automation
Buy labels across 100+ carriers or automate purchasing entirely; tracking posts back to eBay to protect your seller standing.
-
3PL & WMS Routing
Route eBay orders to ShipStation, ShipHero, Extensiv, or any connected partner, with tracking and stock reconciled automatically.
-
Multichannel Expansion
Pair eBay with Amazon, Walmart, TikTok Shop, and your storefront — adding a channel adds revenue, not headcount.
