Fulfillment for eBay Sellers

eBay punishes late shipments, and your seller rating is a moving target. Hand the picking and packing to us and stop sweating Top Rated Seller status. We pull every eBay order automatically — auctions, Buy It Now, and Best Offers — ship same-day from Paramount, CA, and push tracking back so eBay marks your handling on time and your on-time shipment rate stays in the green, every single order.

What syncs automatically

eBay orders flow into our WMS so you can stop printing labels on auction-volume days and protect your seller metrics.

Orders

New eBay orders pull into our WMS automatically — auctions, Buy It Now, and Best Offers all land in the same queue.

Inventory

Available quantity syncs back to eBay listings so you stop selling items you ran out of three days ago.

Tracking

Tracking numbers post back to each eBay order to satisfy handling time requirements and keep your seller metrics clean.

SKU mapping

We map eBay item numbers and variations to your master SKUs so multi-variant listings pick correctly.

Why brands using eBay choose 3PLGuys

Protect your Top Rated Seller status

Same-day handling from our Paramount, CA warehouse keeps your on-time shipment rate well above eBay's thresholds.

Handle wide SKU catalogs

eBay sellers often run thousands of SKUs across mixed categories. Our WMS handles long-tail catalogs without breaking a sweat.

Variation-aware picking

Size, color, and bundle variations map cleanly so the picker grabs the exact item the buyer paid for.

Lower per-order shipping cost

We rate-shop UPS, USPS, FedEx, and DHL on every order so thin eBay margins do not get eaten by shipping.

Returns workflow that fits eBay rules

We receive and inspect returns, log them in your portal, and surface decisions before the eBay return window closes.

Multi-channel inventory pool

Selling on eBay plus Shopify, Amazon, or Walmart? One warehouse, one inventory pool, every channel pulling from the same shelves.
