Merchant-fulfilled selling lives or dies on one discipline: every order confirmed with valid tracking inside the handling time your listing promises. ProShip3PL runs your FBM orders from our Medley, FL racks — daily pick runs, product-matched packing, and carrier handoffs that keep confirmations on schedule day after day.
FBA earns its keep on small, fast-turning products. Step outside that profile and the math bends the other way. Bulky items carry size-based fulfillment fees under Amazon's current schedule that can swallow the margin Prime placement was supposed to fund. Slow movers pay Amazon rent for months while waiting for a buyer.
Then there are the products FBA periodically refuses. Heat-sensitive goods get shut out of the network during Amazon's warm-weather meltable window, and listings without a merchant-fulfilled fallback simply go dark for the season — handing rank and reviews to whoever kept shipping.
The catch is that merchant fulfillment shifts the operational burden — and the performance risk — onto you. Amazon tracks whether merchant-fulfilled orders are confirmed on time with valid tracking, and sustained misses put an account under pressure. That's the job we take over: your orders join our daily pick runs, and confirmations go back inside the handling time your listings state.
| Product situation | Why FBM wins it |
|---|---|
| Oversize or heavy SKU | Skip size-tier fulfillment fees; ship on carriers priced for bulk |
| Slow-turning catalog | No Amazon storage meter running while units wait for buyers |
| Meltable season | Listing stays live while FBA is closed to heat-sensitive goods |
| FBA stockout or stranded stock | Flip to FBM and keep selling from reserve while FBA recovers |
| Branded unboxing or inserts | Your packaging, your inserts — options FBA doesn't allow |
| Testing a new product | Sell before committing inventory into Amazon's network |
Your FBM orders route to our floor automatically — configured with your Seller Central setup or order tool during onboarding, no manual forwarding.
Every unit scanned against the order before it reaches a pack station, so the wrong-item defect never starts its journey.
Boxes, mailers, bubble, or your branded packaging and inserts — pack specs agreed per SKU and repeated identically on every order.
Reinforced cartons and dimension-appropriate carriers for the products FBA prices out — a core FBM specialty, not an exception.
Carrier handoff on daily pickups and tracking confirmed back to Amazon inside your stated handling time — the metric discipline FBM demands.
Customer returns come to us, get inspected and graded, and sellable units go straight back on the shelf for the next order.
A buyer checks out on your FBM listing; the order appears in our pick queue without anyone touching it.
The unit comes off your rack location and is barcode-checked against the order line before packing.
Packed per the SKU's agreed spec — protection matched to the product, inserts included if you use them.
Handed to the carrier on the day's pickup; tracking posts to Amazon inside your handling window.
Self-fulfillment fails exactly when life happens. With orders running through our floor, confirmations continue whether you're at your desk or on a plane.
Bulky goods are FBM's home turf. Shipped from our racks on carriers priced for the dimensions, the unit economics often flip back in your favor — we'll quote it so you can compare.
The meltable window doesn't have to end your season. Convert the listing to FBM, stage stock in our climate-managed space, and ship all summer.
Keep a reserve here and that emergency becomes a settings change: flip to FBM, orders ship from Medley on the next run, rank survives.
The whole merchant-fulfilled cycle: your Amazon FBM orders flow to our floor, units are picked from your stock with barcode verification, packed to suit the product, labeled, and handed to the carrier on our daily pickups — with tracking confirmed back to Amazon inside your stated handling time. Your listings say Fulfilled by Merchant; our Medley, FL warehouse does the fulfilling.
Four patterns come up constantly: oversize or heavy items where Amazon's size-based fulfillment fees under its current terms outweigh the Prime advantage; slow movers that would sit in FBA accruing storage charges; heat-sensitive products during the months Amazon restricts meltable inventory; and any SKU where you want packaging, inserts or carrier choices FBA doesn't offer.
Because Amazon measures merchant-fulfilled sellers on whether shipments are confirmed on time with valid tracking, and a listing's promise dates are built from your stated handling time. Miss confirmations and your account health suffers under Amazon's current performance policies; pad the handling time defensively and your delivery promise gets worse, which costs conversions. Reliable daily fulfillment lets you keep handling time honest and short.
Yes — this is the classic defensive play. Keep reserve stock on our racks, and if FBA inventory strands, sells through or gets stuck inbound, you switch the listing to merchant fulfillment and orders start shipping from Medley on the next pick run. The listing stays live and selling while the FBA pipeline sorts itself out.
Yes. Bulky and heavy goods are one of the main reasons sellers choose merchant fulfillment, so our racking and pack stations are set up for them — oversized cartons, reinforced packing, and carrier selection appropriate to the dimensions. Tell us the product's size and weight in your quote request and we'll confirm handling before anything ships.
We coordinate the connection during onboarding based on how you run your store — order feeds from Seller Central or the order-management tool you already use. Once the flow is set, orders appear in our pick queue automatically; you don't forward anything manually, and confirmations flow back the same way.
Whatever the product needs and you approve: plain boxes, poly mailers, bubble protection for fragile goods, and your own branded packaging or inserts if you supply them — one freedom FBM has that FBA doesn't. We agree pack specs per SKU during onboarding so every order goes out the same way.
That's a core seasonal use case. When Amazon's meltable window closes FBA to chocolate, gummies and similar heat-sensitive goods, sellers keep those listings alive as FBM and we ship them direct from our racks. Our meltable-inventory-storage page covers the storage side of that play in detail.
Yes — FBM means returns come to you instead of Amazon, so we act as your return address: each unit is received, inspected and graded, sellable stock goes back on the shelf for the next order, and you get a report on the rest. You decide dispositions; nothing is discarded without your instruction.
Send monthly order volume, typical SKU sizes and where stock will come from through the form on this page. Pricing is per order and per unit stored, with no setup fee and no monthly minimum — you'll have a rate sheet within one business day.
Monthly order count, product sizes, and where your stock ships from today — that's enough for us to price your merchant fulfillment per order. Rate sheet within one business day, no setup fee, no minimum.
