How It Works

From Your Warehouse to Your Customer's Door

A streamlined 6-step process ensures every order ships fast, accurately, and with full visibility.

Connect

Link Seller Central via MWS/SP-API. Orders sync automatically across FBM and FBA channels.

Inbound

Ship your inventory to our fulfillment centers. We receive and shelve within 24 hours.

FBM Orders

Amazon FBM orders route to our WMS instantly. We pick, pack to Amazon spec, and ship same day.

FBA Prep

Send us inventory for FBA. We label (FNSKU), poly-bag, bubble-wrap, carton, and palletize per Amazon requirements.

Ship to Amazon

We create your FBA shipment plans, print box-level content labels, and send to the right Amazon FC.

Monitor

Track FBM orders, FBA inventory, and IPI score all in one dashboard.

Amazon Fulfillment Options Explained

Amazon sellers have two primary fulfillment options: FBA (Fulfilled by Amazon) where Amazon warehouses and ships your products, and FBM (Fulfilled by Merchant) where you or a 3PL ships directly to customers. Most successful sellers use both.

FBA is powerful for fast-moving, small, lightweight products where Amazon storage fees are manageable. FBM via a 3PL like 3PLCity gives you more control, flexibility, lower costs for large items, and the ability to fulfill the same inventory across multiple channels.

‍

Why Serious Amazon Sellers Use a 3PL

  • Multi-channel inventory: ship the same stock to Amazon FBM, Shopify, and wholesale from one pool
  • FBA prep compliance: professional labeling and packaging that prevents costly Amazon FC rejections
  • Metric protection: same-day FBM shipping keeps your on-time rate, tracking rate, and cancellation rate healthy
  • Avoid long-term storage fees: a 3PL gives you more flexible storage without Amazon penalties
  • Returns control: you decide what happens to returned inventory, not Amazon
