Running your store on Shopify, Trade Me, Amazon and eBay all at once sounds great, until a product sells out on one channel and you’re still taking orders for it on the other three. We set up and manage multi-channel listing and inventory sync so your stock levels, prices and product details stay accurate everywhere, automatically.

Why Choose Us
Why NZ Businesses Choose Web Matrix Lab
Trade Me-First Approach
Unlike agencies that focus only on Amazon and eBay, we build our sync setups around Trade Me from day one, so New Zealand's biggest marketplace is never an afterthought in your strategy.
Real-Time, Reliable Sync
Stock levels, prices and product details update automatically across every platform the moment something changes, so you never oversell or leave customers with outdated information.
Support That Grows With You
As you add new channels or scale up, we're on hand to adjust your setup and keep everything running smoothly, so managing multiple platforms never becomes overwhelming.
1.Audit
We start by reviewing where you currently sell, Shopify, Trade Me, Amazon, eBay or others, and how your inventory, pricing and listings are being managed right now.
2.Connect
We link your platforms together, setting up Shopify (or your chosen platform) as the central source of truth that feeds accurate stock and listing data to every other channel.
3.Sync
Once connected, we configure real-time syncing so stock levels, prices and product details update automatically across every marketplace the moment something changes.
4.Support
We don't disappear after setup. We monitor your sync, troubleshoot issues, and help you add new channels as your business grows, keeping everything running smoothly long-term.

FAQ
Questions & Answers
What is a multi-channel listing service?
A multi-channel listing service connects your online store, such as Shopify, to marketplaces like Trade Me, Amazon and eBay, so your product listings and inventory stay synced and accurate across every platform automatically.
Do you support Trade Me integration?
Yes, and it’s actually central to what we do. Most agencies focus only on Amazon and eBay, but we build our sync setups around Trade Me first, since it’s New Zealand’s leading marketplace
How does inventory sync prevent overselling?
Once your platforms are connected, stock levels update in real time across every channel the moment a sale happens, so you’re never showing an item as available when it’s actually sold out elsewhere.
Â
Which platforms can you connect?
We work with Shopify, Trade Me, Amazon, eBay and Walmart, with Shopify typically set up as your central hub feeding accurate data to every other channel.
Â
How long does setup take?
It depends on how many platforms and products you’re working with, but most multi-channel setups are up and running within a couple of weeks, including testing to make sure everything syncs correctly.
Â
Â
Do I need to manage each platform separately after setup?
No, that’s the whole point. Once everything is connected, you can update a listing once and have those changes reflected automatically across every channel you sell on.
Â
Do you offer ongoing support after setup?
Yes, we monitor your sync, troubleshoot any issues, and help you add new channels as your business grows, so you’re never left managing it alone.
