WMS Integration That Connects Your Warehouse to Every Sales Channel
Shopify orders, Amazon FBA shipments, and eBay inventory should flow straight into your warehouse, without your team retyping a single line. Platton's WMS integration closes the gap between where orders land and where they ship from, so your fulfillment runs on data, not manual effort.
Get a QuoteStep-by-Step Setup and Automation Plan
Step 1: Confirm Your WMS Supports API Connectivity
Most modern WMS software (ShipHero, Extensiv, 3PL Central) supports direct API connections or pre-built connectors to the major sales channels. Before we integrate, we confirm three things:
your WMS has an accessible API or webhook endpoint,
it supports real-time label generation in your carrier formats (Zebra, UPS, FedEx, USPS), and
it can receive order pushes from external platforms.
If all three check out, you are ready to connect. If your system still runs on CSV imports or manual uploads, those create inventory lag and errors at scale, and Platton can build a proper API path on your behalf.
Step 2: Link Shopify, Amazon, and eBay to Your Warehouse
Your sales channels and your warehouse need to run as one system. Platton maps each channel to your WMS so orders arrive with the SKU, quantity, shipping address, and carrier preference already populated, with no manual re-entry. The connection method depends on the channel:
native API and Shopify App Store,
with tools like Zapier, ShipStation, EasyPost, or Extensiv
SP-API integration through Amazon Seller Central,
with ShipStation or a custom connection
eBay API and order sync,
through ChannelAdvisor, ecomdash, or custom middleware
Two-way sync means your warehouse sees every order the moment it is placed, and your sales channels reflect the real stock count the moment it ships. No overselling, and no reconciling platforms by hand at the end of the day.
Step 3: Automate Shipping, Labels, and Tracking
For brands shipping at volume, every manual step is a delay and a potential error. Platton's WMS API integration runs the full order cycle: the order arrives from Shopify or Amazon, routes to the right location in your WMS, the label generates, the carrier is selected by destination and SLA, the tracking number posts back to the sales channel, and the customer gets a shipping notification. Your team picks and packs; the integration handles the rest, around the clock.
On every order you get:
Orders synced automatically from Shopify, Amazon, and eBay into your WMS
Shipping labels generated with the correct carrier, format, and routing, with no manual creation
Status updates pushed automatically to sales channels and customer notifications
Customs documents populated automatically for cross-border shipments
Live tracking fed into your dashboard so your team always knows what is in transit
Step 4: Test the Integration and Go Live
Before anything goes live, every connection gets tested: order data flows from Shopify, Amazon, and eBay into your WMS with zero manual input, stock levels deduct in real time across all channels, labels print with the right carrier and format, and tracking numbers post back to the marketplaces within 30 minutes of pickup. Platton runs the verification cycle and signs off only when every test order passes clean.
We check for:
No duplicate or dropped orders across any channel
Labels that print in the right format for every carrier you ship with
Your WMS, CRM, and ERP showing the same inventory in real time
An operations team that can run the system without spreadsheets or manual workarounds
Once it is verified, fulfillment runs on its own. Your team handles the exceptions, damaged goods, address corrections, carrier delays, instead of the routine work the system now covers.
Shipping Label Automation Built for High-Volume Fulfillment
At 100 orders a day, a 2-minute label delay costs 3 hours. At 1,000 orders, it costs your same-day promise entirely. Your warehouse system should generate the right label for the right carrier in seconds, not after someone picks a template and checks a settings file.
Platton's labeling engine handles:
- Automatic label creation triggered by orders from Amazon, Shopify, or eBay
- SKU, dimensions, weight, country of origin, and shipping tier pulled automatically
- Carrier routing rules by weight, destination, SLA, and product type
- Printing to Zebra, PrintNode, or any network printer by direct API
The result is faster pick-and-pack, fewer mislabeled shipments, and a cost structure that stays lean as you scale, because you are not adding headcount to handle label creation.
Why eCommerce Brands and 3PLs Choose Platton for WMS Integration
Most fulfillment problems are not warehouse problems, they are connectivity problems. Orders that do not sync. Inventory that does not update. Labels that print with the wrong carrier. Platton fixes the connections, so your team can move product instead of troubleshooting data.
What you get:
Integration that connects ShipHero, Extensiv, 3PL Central, and custom WMS to your sales channels by direct API, with no CSV and no manual uploads
Real-time sync between your order channels and your warehouse, so stock updates the moment an order ships
Carrier routing that picks the fastest and cheapest option by weight, destination, and current rates
Custom automation rules for product-specific handling, carrier exceptions, and multi-warehouse routing
A team that speaks both logistics and the technical side, so you are not translating between your warehouse manager and your developer
Whether you ship 200 orders a month or 20,000, Platton connects your stack and keeps it running. Your team stops doing data entry, your customers get accurate tracking, and your warehouse ships on time.
Who Uses Platton's WMS Integration
The integration is built for:
Amazon sellers running FBA and FBM fulfillment in parallel without double-handling
Retail and wholesale importers managing hundreds of SKUs across multiple carriers and warehouses
DTC brands on Shopify outgrowing manual fulfillment and needing real-time inventory accuracy
3PLs that want a reliable plug-in automation layer for the WMS they already run
Cross-border sellers handling customs documentation alongside warehouse fulfillment in one workflow
Whatever your current stack looks like, Platton maps to it. If your WMS is already in place, we connect it. If you are still evaluating options, we help you pick the one that fits your volume and carrier mix.
Where WMS Integration Fits With Platton
WMS integration connects the warehouse and stack you already run. If you would rather Platton run the warehouse and the fulfillment for you, that is a different service. The rest of the platform sits next to it:

when you want Platton to store, pick, pack, and ship, not just connect your system
Cargo Management Platform:
the freight dashboard for every shipment and document
Shipment Tracking:
live ETAs and milestone alerts across carriers
Amazon FBA Prep:
labeling and appointment booking into Amazon fulfillment
Customs Clearance:
ISF, entry filing, and CBP release for cross-border orders
Ready to Stop the Manual Work?
Every order your team keys in by hand, every label they print manually, and every inventory gap they reconcile at month-end is time and money that belongs in your operation, not your spreadsheets. Platton connects your sales channels, your warehouse, and your carriers into one automated flow. Orders arrive, labels print, tracking goes out, without your team touching it.
