eBay integration &
listing automation
Commercium connects eBay to your ecommerce store, ERP, OMS, WMS, shipping and accounting systems over eBay’s Sell APIs. It syncs products, inventory, orders, shipments, cancellations, price and item-specifics updates, refunds and settlements, and it relists listings automatically and moves older listings onto the Inventory API.
28-day free trial. No credit card. Sign in with eBay. We never ask for your eBay password.
What Commercium solves for eBay sellers
Commercium connects eBay with ecommerce, OMS, ERP, WMS, shipping and accounting platforms. Products, inventory, orders, shipments, refunds and settlements stay in sync across all of them.
Your systems
Store · ERP · OMS · WMS · 3PL
Maps, transforms, schedules, validates and retries every eBay flow, and handles relisting and legacy-listing migration
eBay
Inventory · Fulfillment · Finances APIs
Large catalogs across tools that don’t connect
Many eBay sellers have years of listings built in Seller Hub, bulk files and older tools. Without one integration, keeping them accurate is daily manual work.
E-commerce platforms
Connect your store to eBay to list its catalog there, then run one product set and one stock pool for both.
ERP systems
Connect your ERP to turn eBay orders into sales orders and keep stock, cost and finance in one source of truth.
OMS, WMS & 3PL
Connect your warehouse or 3PL to route each eBay order to the right location and close it with a tracking number.
Shipping & carriers
Connect shipping to send labels and tracking into eBay’s shipping fulfilment without copying numbers by hand.
Accounting platforms
Connect accounting to match eBay sales, refunds, fees and payouts to your books.
Other channels & POS
Connect your other marketplaces and POS so every sale draws from one stock pool and an eBay order never oversells another channel.
Click the platform you want to integrate with eBay
Run eBay alongside your own store, your ERP and every other channel you sell on, all in one application and on one plan.

What eBay is, and what selling on it involves
eBay is one of the world’s largest online marketplaces. It connects buyers and sellers in more than 190 markets across new, used, refurbished and collectible goods. Business sellers list through Seller Hub or eBay’s Sell APIs, keep and ship their own stock, and get paid out by eBay.
A global, open marketplace
eBay is one of the world’s largest online marketplaces. Businesses and individuals sell new, used, refurbished and collectible items, and eBay runs the storefront, search and checkout.
Many country sites, one account
eBay runs country sites including the US, UK, Germany, Australia, Canada, France, Italy and Spain. One seller account can list on several sites, and each listing belongs to one site with its own currency and policies.
Fixed price and auction formats
Most business sellers use fixed-price listings, which are Good ’Til Cancelled and renew automatically each month. Auctions run for a set duration. Multi-variation listings group sizes, colours and styles under one listing.
Business policies
Payment, shipping and return terms are saved as reusable business policies and attached to listings. Listings created through the Inventory API must use them.
Seller performance standards
eBay rates sellers as Top Rated, Above Standard or Below Standard. The ratings use transaction defects, late shipment rate and whether valid tracking is uploaded within your handling time.
eBay manages payments
eBay collects payment from buyers and pays sellers out on a schedule. Fees are deducted before each payout, and transactions, fees and payouts are all available through the Finances API.
Connect your account on a call. We’ll scan your listings, show you which ones need migrating, and run the first batch with you.
From eBay seller to a live integration
Six steps from an eBay business account to a live Commercium connection: policies, OAuth, catalog mapping, migration and ongoing sync.
Set up an eBay business account
Register or upgrade to an eBay business seller account and open Seller Hub. New accounts may start with selling limits that eBay raises as you build history. Commercium can join from day one to plan the integration in parallel.
Opt in to business policies
Create payment, shipping and return policies for each eBay site you sell on. API-created and migrated listings need them, so we help you define them around your real carriers, handling times and return terms.
Connect eBay to Commercium
Sign in through eBay’s consent screen from Commercium. eBay issues a secure token that lets Commercium manage listings, orders, fulfilment and finances for the sites you choose. No password is shared.
Prepare catalog data
Map your catalog to eBay categories, item specifics, condition and product identifiers, so nothing is retyped for each channel and listings are complete when they publish.
Migrate & publish listings
Existing listings are migrated to the Inventory API with their listing IDs kept. New products are published as offers. Commercium reports any listing that eBay rejected and the reason.
Operate & monitor
After go-live, inventory syncs in near real time, and orders, shipments, refunds and settlements every few minutes. Relist rules run in the background, and alerts catch problems before they affect your seller standards.
What we learnt while integrating eBay for our users
Notes from live eBay integrations: the issues that decide whether an eBay account runs smoothly, and how we automated each one in Commercium.
Older listings can’t be updated by the Inventory API, so we migrate them
eBay’s Inventory API can only update listings it created. Listings built in Seller Hub, through bulk upload tools or with the older Trading API are outside its reach. Many long-standing sellers have years of these listings, and modern integrations can’t change their stock or price.
Commercium finds these listings automatically and moves them to the Inventory API using eBay’s own migration process. It turns each one into an inventory item and offer under the same listing ID. The sales history, watchers and buyer feedback on that listing stay intact, and the seller doesn’t have to recreate anything.
Ended listings quietly cost sales, so relisting runs on rules
A listing can end without anyone deciding to end it. Stock runs out without out-of-stock control turned on, a scheduled listing expires, or an item sells through. Each ended listing is a product buyers can no longer find, and sellers usually notice only when sales drop. Commercium watches for ended listings and relists them using your current catalog data, following the rules you set.
Ops teams want listing control without another login
Teams running several eBay accounts and sites don’t want to switch into Seller Hub to pull a product during a supplier recall or stock problem. In Commercium, delist and relist are actions on the product list: one SKU or a bulk selection, across every connected eBay account, with each result recorded.
Item specifics drive visibility
Buyers filter eBay search by brand, size, colour, MPN and other item specifics. Listings that leave out required or recommended aspects lose placement, so we map them per category instead of leaving them as free text.
Each eBay site is its own listing
Selling on eBay US and eBay UK means two listings, with separate currency, prices, policies and stock allocation. We keep one source catalog and apply per-site rules.
Out-of-stock control protects history
With eBay’s out-of-stock option turned on, a listing at zero quantity is hidden instead of ended, so it keeps its listing ID and sales history. We recommend it, and we relist by rule when a listing has ended.
Business policies come first
Inventory API listings can’t be published without payment, shipping and return policies. Setting these up per site before the first publish avoids a wave of rejected offers.
Handling time is a promise
Valid tracking uploaded within the stated handling time counts toward seller standards. A tracking number sent at the end of the day can still be late, so we upload tracking at dispatch.
Variations need clean SKUs
Multi-variation listings need a unique SKU for every variation, and those SKUs are the key the Inventory API works with. We check variation SKUs against your ERP before publishing or migrating.
Auctions aren’t migrated
eBay’s migration only covers fixed-price listings. We leave auction listings as they are and manage fixed-price inventory through the Inventory API.
Some legacy settings get locked
A few features, such as listing-level buyer requirements and paid enhancements like bold titles, stay on a migrated listing but can no longer be changed. We flag these before migrating.
Payouts need fee-level detail
A payout total alone won’t reconcile. We pull each sale, refund and fee from the Finances API so every payout matches the orders in your accounting system.

eBay questions, answered
Technical questions about how the eBay integration works, and general questions about running on Commercium.
Can Commercium create products on eBay?
Can eBay orders be sent to my ERP?
Can Commercium help new eBay sellers?
Can I connect more than one seller account of eBay using Commercium?
What are the next steps to connect eBay using Commercium?
There are six steps.
1. Start your Commercium account with the 28-day free trial or a demo, and confirm your eBay sites and flows.
2. Add eBay as a channel and sign in on eBay’s consent screen. Your password is never shared.
3. Commercium scans your active listings, fixes missing SKUs or business policies, and migrates legacy listings to the Inventory API with their listing IDs kept.
4. Connect your ecommerce store, ERP, OMS, WMS, shipping and accounting platforms.
5. Map categories, item specifics, condition, business policies, inventory locations, price rules and relist rules.
6. Publish a test batch, run test orders, shipments and refunds, then switch on the full catalog and go live.
My listings were created in Seller Hub or another tool. Can Commercium update them?
Will migrating to the Inventory API change my listing IDs or lose sales history?
Can Commercium relist expired or ended eBay listings automatically?
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 about your catalog, your eBay accounts and your back-office systems, and we’ll show you exactly what the integration looks like.
