Multi-Channel Fulfillment · Shenzhen, China · 15 Years

One warehouse.
Every channel you sell on.

Updated · By China Fulfillment International Shenzhen

Selling on Shopify and Amazon and TikTok Shop usually means the same product living in three separate inventory pools, three separate order queues, and a spreadsheet somewhere trying to keep them from contradicting each other. That is how sellers oversell a bestseller the week it actually starts moving.

We run one physical stock pool in Shenzhen behind every channel you connect. Sell it on Shopify, TikTok Shop, Amazon or as a crowdfunding reward, and the same warehouse fulfils it from the same shelf, with inventory that updates everywhere the moment a unit ships.

The Problem With Selling Everywhere

Every channel you add is another place stock can silently go wrong

Multi-channel selling grows revenue and multiplies a very specific operational risk: the same unit committed twice because two platforms do not know about each other.

None of this is a platform problem. Shopify, TikTok Shop and Amazon each do their own job well. It is an inventory architecture problem: the stock sits in separate pools because nothing is telling all three where the real count actually is.

How It Actually Works

One warehouse, one inventory count, every channel reading the same number

The mechanism is simple even though the platforms are not: every channel connects to the same warehouse management system, and that system holds one number per SKU.

One physical stock pool, not a sync job between five

Every channel reads and writes against the same warehouse inventory record. There is no reconciliation step because there is nothing to reconcile: it was never split in the first place.

Orders arrive automatically, tracking writes back automatically

Shopify and WooCommerce push orders the moment they are placed. Amazon connects via SP-API. Tracking numbers write back to the platform on dispatch, so your customer gets their shipping confirmation from your own store, not from us.

Scoped Honestly

What this is, and what it is not

"Omnichannel" gets used loosely. Some 3PLs mean unifying wholesale, retail replenishment and EDI to big-box retailers alongside DTC. That is not what we sell, and we would rather tell you that up front than have you find out after signing.

Yes

Every DTC and marketplace channel, one stock pool

Shopify, WooCommerce, TikTok Shop, Amazon Seller Central, eBay and crowdfunding rewards, all fulfilled from the same Shenzhen warehouse against the same inventory count, on our standard D2C eCommerce fulfillment terms.

This is what most sellers mean by omnichannel
Yes

Real-time stock sync, not a nightly batch

A sale on one channel reduces available stock on every other connected channel immediately, which is what actually prevents overselling.

The oversell problem goes away
Yes

One inventory pool for launches and ongoing sales together

A Kickstarter reward tier and a Shopify pre-order draw from the same physical units, so a campaign does not need its own separate stock pool.

No more splitting inventory for a launch
No

EDI into Walmart, Target or other big-box retail programmes

We do not run retail replenishment EDI. If wholesale accounts with major retailers are part of your channel mix, you need a 3PL built for that specific requirement.

No

Buy-online-pickup-in-store logistics

We do not operate retail-facing infrastructure in destination markets, so BOPIS-style fulfillment is outside what we do.

Maybe

Custom platforms and marketplaces we have not named

Our REST API covers order creation, inventory queries, tracking lookup and inbound shipment creation. If a channel is not on our direct-integration list, this is usually how it still connects.

Questions

Questions about multi-channel fulfillment

Is this the same as omnichannel fulfillment?
Partly. In the DTC and marketplace sense, yes: one inventory pool serving Shopify, WooCommerce, TikTok Shop, Amazon and crowdfunding orders, with real-time stock sync across all of them. What we do not offer is the retail and wholesale side some 3PLs mean by omnichannel: EDI to big-box retailers, B2B replenishment, or buy-online-pickup-in-store logistics. If that is what you need, we are not the right fit. If you mean every direct-to-consumer and marketplace channel from one warehouse, that is exactly what this is.
Which platforms actually connect?
Shopify and WooCommerce connect directly through an app or plugin, live within one to two business days. Amazon Seller Central connects via SP-API authorisation, typically two to three days. eBay and custom platforms connect through our REST API, which covers order creation, inventory queries, tracking lookup and inbound shipment creation. Anything without a direct integration can run on CSV, XML or XLS file upload, manual or scheduled via FTP.
Is inventory really shared across every channel, or allocated separately?
Shared. One physical stock pool in our Shenzhen warehouse serves every connected channel. When a unit sells on TikTok Shop, the quantity available on Shopify and Amazon drops at the same time. That is what prevents overselling when a product is listed in more than one place, which is the operational problem multi-channel sellers actually run into.
Do tracking numbers write back to each platform automatically?
For direct integrations, Shopify, WooCommerce and Amazon, tracking numbers write back automatically the moment we dispatch, and your customer gets their shipping confirmation from your own store. For API and file-based setups, tracking numbers are available by API query or in your daily status export.
Can crowdfunding backers and store customers ship from the same stock?
Yes. A Kickstarter or Indiegogo reward tier and a Shopify pre-order can draw from the same physical inventory, so you are not splitting stock into separate pools for a campaign versus your ongoing store. Upload a backer CSV once and we fulfil it alongside your regular order flow.
What do you not do that a full omnichannel 3PL might?
We do not run EDI connections into Walmart, Target or other big-box retail replenishment programmes, and we do not handle buy-online-pickup-in-store logistics, because we do not operate retail-facing infrastructure in destination markets. If your channel mix includes wholesale accounts with retailers, you likely need a US or EU-based 3PL alongside us, not instead of us, for that specific piece.
