What Commercium solves for Walmart sellers
Commercium connects Walmart with E-commerce, OMS, ERPs, WMS, Shipping & Accounting platforms, enabling seamless product, inventory, order, shipment, price and refund synchronisation across your commerce platforms.

Store · ERP · OMS · WMS · 3PL
Maps, transforms, batches feeds, tracks status & retries every Walmart flow

Marketplace API · Seller Center
A Walmart account run from Seller Center
Walmart holds sellers to strict performance standards on shipping, tracking and cancellations. Without an integration, keeping up means spreadsheets, uploads and someone watching Seller Center all day.
E-commerce platforms
Connecting Walmart with your ecommerce store lets you publish your store catalog to Walmart, then run one product set and one stock pool across both.
ERP systems
Connecting your ERP turns Walmart orders into sales orders and keeps item, cost, stock and finance data in one source of truth.
OMS, WMS & 3PL
Connecting your warehouse or 3PL routes each seller-fulfilled Walmart order to the right ship node and closes it with tracking.
Shipping & carriers
Connecting shipping keeps Walmart’s delivery promise honest, labels from your carriers, tracking back to Walmart, templates aligned to what you can ship.
Accounting platforms
Connecting accounting keeps every Walmart order, refund and fee matched to a payout in your books.
Other channels & POS
Connecting your other marketplaces and POS brings every sale into the same stock pool, so a Walmart order never oversells another channel.
Everything Commercium connects to your Walmart seller account
Run Walmart alongside your own store, your ERP and every other channel you sell on, through the same application, on the same plan.

Setting up Walmart in Commercium
Six steps from your Commercium account to live Walmart sync: API keys, platform connections, mapping and go-live.
Start your Commercium account
Start the 28-day free trial or book a demo. Tell us which systems hold your catalog, stock, orders and finance data, whether you ship Walmart orders yourself, use WFS, or both. We confirm the right plan category before you subscribe.
Generate Walmart API keys
In Walmart Seller Center, open API key management and generate production keys for your seller account. We send you the exact steps and never ask for your Seller Center password.
Connect Walmart in Commercium
Add Walmart as a channel and paste your Client ID and Client Secret. Commercium validates the connection straight away, reads your ship nodes and shipping templates, and pulls existing items and recent orders so you see real data before anything changes.
Connect your other platforms
Connect the systems Walmart needs to talk to, your ecommerce store, ERP, OMS, WMS, shipping app and accounting platform. Most platforms connect on your existing plan, and your integration engineer does this with you.
Map products, ship nodes & shipping
Map it once so every item and order follows the same rules: product types and attributes, identifiers or GTIN exemption, warehouses to ship nodes, shipping templates per SKU, price source and carrier mapping.
Publish, go live & monitor
Commercium submits your items as Walmart feeds and tracks every feed until each item is processed. Errors come back per item with Walmart’s reason, so you fix data once in Commercium. Then inventory, price, order and shipment sync switch on.
What Walmart Marketplace is, and what selling on it involves
Walmart Marketplace lets approved third-party sellers list on Walmart.com, one of the most visited retail sites in the US, alongside Walmart’s own range. Sellers manage the account through Seller Center and the Walmart Marketplace API, and fulfil orders themselves or through Walmart Fulfillment Services.
A curated marketplace, not open sign-up
Walmart Marketplace accepts sellers through an application and review. Approved sellers list alongside Walmart’s own retail range on Walmart.com, under their own seller name.
One item page per product
Walmart matches offers to a single item page, keyed on product identifiers such as GTIN or UPC. Products without one can be created through Walmart’s GTIN exemption process.
Product type drives the data
Each product type has its own required and recommended attributes. Complete, accurate attributes decide whether an item publishes and how well it is found.
Two ways to fulfil
Sellers can ship orders from their own warehouses or 3PL, or send stock into Walmart Fulfillment Services (WFS) and let Walmart pick, pack and ship.
Shipping templates set the promise
Seller-fulfilled items are assigned to shipping templates that define methods, regions and transit times, the delivery date a customer sees comes from them.
Performance is measured
Walmart tracks on-time delivery, valid tracking, cancellations and refunds. Staying inside the standards protects your listings and Buy Box eligibility.
Bring your API keys to a call, we will connect your account, match your existing items and show your live orders flowing into your systems the same day.
What we learnt while integrating Walmart for our users
Working notes from live Walmart Marketplace integrations, the things that decide whether a Walmart account runs quietly, and how each one became automation inside Commercium.
Walmart bulk updates are asynchronous, so we track every feed
Walmart supports bulk, feed-based uploads for products, inventory and prices. A feed is accepted first and processed later: Walmart returns a feed ID, and the result, including which individual items failed and why, only appears when you check the feed status. Feed submissions are also rate-limited. Integrations that fire and forget end up with items that silently never published. Commercium batches updates into feeds within Walmart’s limits, follows each feed ID until it completes, and surfaces item-level errors so only the failed lines are fixed and resent.
Shipping templates set the delivery promise, keep them honest
Walmart supports templated shipping policies for seller-fulfilled items. A shipping template defines shipping methods, such as value, standard, two-day, one-day and freight, along with regions and transit times, and each SKU is assigned to a template. The delivery date a customer sees comes from that template, so a template that promises more than your warehouse can do turns directly into late deliveries. Commercium reads your templates, assigns them per SKU or product group, and keeps freight and oversized items on their own template.
No GTIN doesn’t mean no Walmart listing
Private-label, handmade and bundled products often have no barcode, GTIN or other global identifier, and many sellers assume that rules them out of Walmart. Walmart offers a GTIN exemption path for these products. Items created this way can go through an extra review before they publish, so a feed may finish while the item itself is still pending. Commercium helps you create these products with the exemption, and keeps following each item until its review completes.
Attributes decide if an item publishes
Each Walmart product type has its own required attributes. Most item errors we see are missing or mis-formatted attributes, so we validate against the product type before the feed is sent.
Acknowledge orders quickly
Walmart orders need to be acknowledged before they ship. Acknowledging automatically on import keeps orders moving and avoids them sitting unconfirmed in Seller Center.
Carrier names must match Walmart’s list
Valid tracking depends on carrier names Walmart recognises. We map each carrier and service from your shipping app to Walmart’s accepted values so tracking is counted as valid.
Inventory belongs to a ship node
Sellers with more than one warehouse publish stock per ship node. Sending one pooled number to the wrong node promises stock a warehouse cannot ship; we keep feeds per location.
Refunds are line-level
Walmart refunds and cancels per order line, often partially. Syncing at line level keeps ERP credit memos and stock adjustments matched to exactly what Walmart refunded.
Settlements need order-level detail
A Walmart payout combines sales, fees, commissions and refunds. Matching settlement lines back to individual orders is what makes Walmart revenue reconcile in accounting.

Walmart questions, answered
Technical questions about how the Walmart integration works, and general questions about running on Commercium.
Can Commercium create products on Walmart?
Can Walmart orders be sent to my ERP?
Can Commercium help new Walmart sellers?
Can I connect more than one seller account of Walmart using Commercium?
What are the next steps to connect Walmart using Commercium?
Six steps.
First, start your Commercium account with the 28-day free trial or a demo and confirm your flows and fulfilment model (WFS, seller fulfilled or both). Second, generate a Client ID and Client Secret in Walmart Seller Center under API key management. Third, add Walmart as a channel in Commercium and paste the keys, your ship nodes, shipping templates and existing items are read automatically. Fourth, connect your ecommerce store, ERP, OMS, WMS, shipping and accounting platforms. Fifth, map product types and attributes, identifiers or GTIN exemption, warehouses to ship nodes, shipping templates, price source and carriers. Sixth, publish your items as Walmart feeds, fix any item-level errors, switch on inventory, price and order sync and go live.
Can I list products on Walmart if they don’t have a barcode or GTIN?
Does Commercium support both Walmart Fulfillment Services (WFS) and seller-fulfilled orders?
How does Commercium handle Walmart bulk feeds for products, inventory and prices?
Does Commercium support Walmart shipping templates?
How are Walmart cancellations, refunds and settlements handled?
Is there a free trial available?
Can I sell on multiple marketplaces using Commercium?
You can connect and manage multiple sales channels through a single Commercium subscription without purchasing a separate connector for each platform. Some enterprise and ERP integrations may require a higher-tier plan.
Does every order I receive on any channel get counted against my plan order limit?
For example, if you already sell through Shopify and use Commercium to connect three additional marketplaces, only orders received from those three marketplaces count toward your Commercium order limit. Your existing Shopify orders are not counted unless Shopify is also connected to Commercium as a sales channel for order processing.
Most supported platforms can be added without a separate per-connector fee, provided they are covered by your current plan category.
How frequently does data sync happen between connected platforms?
What happens when I cross my plan limit?
You can also upgrade to a higher plan if you consistently exceed your plan limits, as higher-volume plans can cost less.
Can I connect my shipping platform with Commercium?
This allows you to send orders for fulfilment and synchronize shipment and tracking information with your connected sales channels.
Can I connect my ERP and accounting software with Commercium?
These integrations can synchronize products, inventory, pricing, orders, fulfilment information, and accounting data, depending on the capabilities of each connected system.
What kind of support does Commercium offer?
The support channels and service levels available may vary by plan.
Why are there three different types of pricing plans?
Ecommerce pricing applies when your setup includes only platforms classified as standard ecommerce integrations.
Enterprise pricing applies when your setup includes an enterprise marketplace, retailer, fulfilment network, or another platform classified as an enterprise integration.
ERP pricing applies when your setup includes an ERP system such as Business Central, Odoo, Acumatica, or NetSuite.
If your setup includes an Enterprise or ERP integration, the corresponding pricing category will apply. Our team can review your requirements and confirm the appropriate plan before you subscribe.
Tell us your catalog, your Walmart seller setup and your back-office systems, and we’ll show you exactly what the integration looks like.
