FBM fulfillment for Amazon Sellers

Amazon sellers tend to start with FBA, then hit a wall — long-term storage fees, inbound restrictions, commingling, lost units. FBM gives back control, but only if your fulfillment can match Amazon's delivery promise. We ship Amazon orders same-day from Paramount, CA with carrier service tiers that hit Prime-comparable transit. Inventory stays separated, branded, and accurately counted.

What syncs automatically

Amazon FBM and Seller Fulfilled Prime orders shipped fast enough to compete with FBA — without FBA's storage fees or commingling risk.

Orders

FBM orders from Seller Central flow into our WMS via SP-API as soon as Amazon releases them.

Inventory

Available quantities sync back to Seller Central so listings show real stock and you avoid suppression.

Tracking

Valid tracking numbers post to Amazon within seller metric windows, protecting your VTDR and OTDR scores.

Returns

Buyer-initiated returns reconcile against the Amazon order so refunds, restocking decisions, and inventory stay aligned.

Why brands using Amazon choose 3PLGuys

MCF alternative without FBA's downside

Amazon's Multi-Channel Fulfillment is convenient until you need to ship off-Amazon. We fulfill Amazon orders and your DTC orders from the same building, no MCF markups.

Seller Fulfilled Prime ready

If you're approved for SFP or working toward it, we have the carrier mix and SLA discipline to hit the on-time delivery metrics Amazon requires.

Inventory stays yours, no commingling

Your units, your SKUs, your lot codes, your boxes. No FBA commingling pool, no risk of counterfeit units shipping under your brand.

Protects your seller metrics

Same-day shipping, valid tracking, on-time delivery — the inputs Amazon scores you on. We treat your VTDR, OTDR, and LSR as our scoreboard too.

No long-term storage fees

FBA punishes slow-moving SKUs. Our storage pricing is flat and predictable, so slow movers don't burn margin every month.

Multi-channel from one inventory pool

Sell on Amazon plus Shopify, TikTok Shop, Walmart, your B2B portal — all out of one warehouse with one inventory pool, no FBA transfers.

How the integration works

Connect your Amazon account and ship within days, not months.

1

Connect Seller Central via SP-API

Authorize our integration in Seller Central. We pull orders, push inventory, and post tracking via Amazon's SP-API on a real-time cadence.

2

Inventory to Paramount, not FBA

Ship inventory to our warehouse instead of an FBA fulfillment center. We receive, count, and SKU-map within 24-48 hours so Seller Central reflects accurate stock.

3

Orders ship under your tracking

FBM orders flow in, we pick and pack same-day, valid tracking posts back to Amazon inside the metric window, customer gets the package in 2-3 days.

Built for Amazon sellers

Brands leaving (or supplementing) FBA

Long-term storage fees, IPI restrictions, inbound caps. We give you the FBM path that doesn't sacrifice delivery speed.

Sellers chasing Seller Fulfilled Prime

SFP demands strict on-time delivery and weekend cutoffs. Our fulfillment cadence and carrier mix are built to hit those metrics.

Multi-channel sellers tired of FBA-to-everywhere transfers

Selling on Amazon plus your own DTC site? Moving inventory between FBA and a separate 3PL is expensive and slow. One pool fixes it.

Brand-controlled sellers

If your brand needs branded packaging, inserts, or careful presentation, FBA's standardized boxes won't cut it. We pack it the way you want it shipped.
