An Amazon 3PL partner built for multi-channel sellers

Selling on Amazon is rarely the whole picture. Most growing brands also run a Shopify store, a Walmart account, or a wholesale channel, and inventory has to keep moving across all of them at the same time.

That is where a strong Amazon 3PL partner can help. Instead of splitting your stock across separate fulfillment setups, the right partner can support FBA prep, FBM orders, and other channels from one place.

R&S Warehousing Solutions works with Amazon sellers who want cleaner FBA prep, reliable FBM fulfillment, and fewer headaches managing inventory across multiple storefronts.

FBA prep done right

Labeling, polybagging, bundling, and forwarding to Amazon fulfillment centers, prepared to Amazon’s requirements.

FBM order fulfillment

Pick, pack, and ship FBM orders directly to your Amazon customers with consistent turnaround.

One inventory pool, many channels

Run Amazon alongside Shopify, Walmart, and other storefronts without splitting your stock across multiple warehouses.

FBA vs 3PL

FBA vs a dedicated 3PL — or both?

For many Amazon sellers, FBA is the default starting point. It plugs into Prime, handles last-mile shipping, and works well when your operation is built around Amazon alone.

But once you sell on more than one channel, things get harder. FBA storage fees climb, inventory gets stuck inside Amazon, and FBM orders, Shopify orders, and wholesale shipments all need to come from somewhere else anyway.

A dedicated Amazon 3PL gives you one place to prep FBA shipments, fulfill FBM orders, and ship to every other channel from the same inventory pool. For most multi-channel brands, it is not FBA or a 3PL — it is FBA plus a 3PL.

FBA on its own

Amazon FBA can work when Amazon is your only channel

If you sell exclusively on Amazon and have predictable volume, FBA on its own may be enough to keep things moving.

When a 3PL makes sense

A 3PL becomes important as you add channels and complexity

Once Shopify, Walmart, FBM, or wholesale enter the mix, splitting inventory across multiple setups creates real operational friction.

The stronger long-term setup

FBA prep plus 3PL fulfillment from one inventory pool

Prep and forward FBA shipments, fulfill FBM orders, and ship every other channel from the same warehouse, all under one team.

Why It Helps

Why Amazon sellers work with a 3PL partner

A strong Amazon 3PL helps you control FBA costs, protect your seller metrics, and run Amazon alongside every other channel without splitting your operation in half.

Compliant FBA prep

Labeling, polybagging, and bundling done to Amazon’s requirements before shipments leave the warehouse.

Lower FBA storage exposure

Keep buffer stock in a 3PL and forward to Amazon as needed to help reduce long-term storage costs.

FBM order coverage

Keep selling when FBA goes out of stock or you need more control over packaging and shipping.

One inventory, every channel

Ship Amazon, Shopify, Walmart, and wholesale from the same stock instead of managing separate pools.

Returns handled cleanly

Process Amazon returns, inspect product, and put resellable units back into rotation without slowing your team down.

Tailored Setup

No two Amazon operations look the same

Every Amazon seller runs a different mix. Some lean heavily on FBA. Others are mostly FBM. Many run Amazon alongside Shopify, Walmart, or wholesale, and the balance shifts as the business grows.

That is why R&S does not force every account into the same template. The setup depends on your channels, your prep requirements, your packaging, and how your inventory moves day to day.

For some sellers, the rollout is quick. For others, it takes more time to map out FBA prep workflows, FBM SLAs, kit and bundle structures, and how returns should be handled. Either way, the goal is the same: a setup that fits how your business actually runs.

FBA-heavy sellers

Prep, label, bundle, and forward shipments to Amazon FCs on a cadence that fits your replenishment plan.

FBM and multi-channel sellers

Fulfill Amazon FBM orders alongside Shopify, Walmart, and wholesale from a single inventory pool.

Mixed and seasonal operations

Handle bundles, variations, peak-season spikes, and shifting channel mixes without forcing your team to rebuild the process.

Implementation

An Amazon setup process built around your operation

Good Amazon fulfillment starts well before the first FBA shipment leaves the dock.

To set up your account properly, R&S works through the details that matter: ASIN and SKU mapping, FNSKU labeling requirements, polybag and bundle specs, carton and pallet labeling, dimensional info, and how Amazon orders should sync with your other channels.

This implementation work helps make sure your FBA shipments meet Amazon’s requirements the first time, your FBM orders ship within SLA, and your inventory stays accurate across every storefront.

Before product arrives, the team prepares the warehouse and tests the integration setup so launch day looks like a normal day, not a fire drill.

ASIN, SKU, and FNSKU mapping

Clean product identifiers and labeling structure so FBA shipments and FBM orders move without confusion.

FBA prep requirements

Polybagging, bundling, suffocation warnings, expiration dating, and carton labeling handled to Amazon’s specs.

Multi-channel integration

Connect Seller Central alongside Shopify, Walmart, or other platforms so one stock pool can serve every channel.

Testing before go-live

Test orders, label proofs, and prep samples are reviewed so the first real shipment is not the first time anything is checked.

Direct Support

An Amazon 3PL partner that feels like part of your team

Amazon moves fast. Listings change, replenishment windows shift, IPI scores fluctuate, and a single FBA rejection can knock a hot SKU offline for days.

When that happens, you do not need a support portal. You need to reach a real person who knows your account, your products, and your prep requirements, and who can help solve the problem in hours instead of weeks.

R&S works to be that kind of partner. Direct contacts, real communication, and a team that understands how Amazon sellers actually operate.

Direct contacts

Reach real people who know your account instead of getting routed through a generic support queue.

People who understand Amazon

Support is stronger when the team knows FBA prep rules, FBM SLAs, and the difference between a routing issue and a labeling issue.

Fast response when it matters

Replenishment changes, peak-season pushes, and last-minute prep adjustments handled without waiting on a ticket queue.

Real People

Work with people who understand Amazon operations

Behind the systems and warehouse processes, you get direct support from people who understand customer relationships, prep detail, and continuous improvement. That is part of what makes R&S feel like a real partner instead of just another vendor.

FAQ

Common questions about Amazon 3PL fulfillment

Here are the questions Amazon sellers ask most when evaluating a 3PL partner for FBA prep, FBM fulfillment, and multi-channel operations.

What is an Amazon 3PL? +

An Amazon 3PL is a third-party logistics partner that stores your inventory and helps move it across Amazon and other channels. That can include FBA prep and forwarding to Amazon fulfillment centers, FBM order fulfillment directly to customers, returns processing, and shipping for any other ecommerce channels you run.

Do I need a 3PL if I already use Amazon FBA? +

Many sellers use both. FBA handles Prime fulfillment, while a 3PL gives you somewhere to hold buffer stock, prep new shipments to Amazon, fulfill FBM orders during stockouts, and ship to other channels like Shopify or Walmart from the same inventory pool.

Does R&S handle Amazon FBA prep? +

Yes. R&S handles FBA prep services including FNSKU labeling, polybagging, bundling, carton labeling, and forwarding shipments to Amazon fulfillment centers based on your replenishment plan.

Can R&S fulfill FBM (Fulfilled by Merchant) orders? +

Yes. R&S supports FBM order fulfillment, which is useful for keeping listings active during FBA stockouts, handling oversized or restricted items, and maintaining more control over packaging and shipping.

Can I run Amazon alongside Shopify, Walmart, and other channels? +

Yes. R&S is built for multi-channel sellers. You can keep one inventory pool that supports Amazon FBA prep, Amazon FBM orders, Shopify orders, Walmart orders, and wholesale shipments without splitting stock across separate warehouses.

How are Amazon returns handled? +

Returned units can be inspected, graded, and either put back into resellable inventory or set aside for disposition. The goal is to recover as much sellable stock as possible instead of letting returns turn into dead inventory.

Is R&S a good fit for growing Amazon brands? +

R&S is a strong fit for Amazon sellers who run more than one channel, want cleaner FBA prep, need reliable FBM coverage, and prefer a 3PL that communicates directly instead of routing everything through a support portal.
