You’ve Already Invested in NetSuite
Your items, inventory, customers, finance and fulfilment already run through NetSuite. Now marketplaces are the next growth opportunity: Amazon, eBay, Walmart, Wayfair, B&Q, Tesco, Zalando and more.
But most marketplace tools are built around a web store, not an ERP. The result is stock levels drifting out of sync, orders exported and re-keyed by hand, refunds that never match up in your accounts, and a finance team reconciling marketplaces in spreadsheets.
ChannelUnity works the other way round. NetSuite stays at the centre of your business, and every marketplace becomes a sales channel that it feeds.
How ChannelUnity Connects to NetSuite
NetSuite as the Master, Marketplaces as Channels
ChannelUnity connects directly to your existing NetSuite account and manages the full flow of data in both directions.
Items, Pricing and Stock out of NetSuite
ChannelUnity reads your item records from NetSuite, including pricing and inventory by location. Stock is kept in sync across every channel, with safety stock buffers to stop fast-moving lines from overselling. Product data is mapped to each marketplace’s categories, attributes, variations and listing templates, and you can add marketplace-specific content in ChannelUnity without cluttering your ERP.
Orders, Customers and Payments into NetSuite
Every marketplace order is created in NetSuite as a sales order. ChannelUnity finds or creates the customer record and can raise the matching customer deposit, so payment is recorded against the order from the start. It supports:
- Multiple subsidiaries and currencies
- Location and warehouse assignment at order or line level
- Channel-specific payment methods, accounts, classes and custom fields
- Marketplace-fulfilled orders (such as Amazon FBA) handled separately from orders you ship yourself
Fulfilments and Tracking back to the Marketplace
When an order is fulfilled in NetSuite, ChannelUnity sends the shipment confirmation and tracking details to the right marketplace automatically, protecting your seller metrics without anyone logging in to Seller Central.
Cancellations, Refunds and Returns
Post-sale activity is where most integrations stop. Depending on your configuration, ChannelUnity can close cancelled sales order lines, raise credit memos and customer refunds, and create return authorisations for marketplace returns, including Amazon FBA and merchant-fulfilled returns.
Marketplace Finance Data
An order tells you a sale happened, not what you were actually paid. ChannelUnity can bring Amazon financial data such as fees, refunds and adjustments into NetSuite, so reconciliation happens in your ERP instead of a spreadsheet. Read more about syncing marketplace financial data.
Your Web Store Can Be a Channel Too
Run Shopify, BigCommerce or Magento alongside NetSuite? ChannelUnity can treat your store exactly like a marketplace, fed from NetSuite with orders flowing back the same way, making it simple to launch extra storefronts for new brands or regions.
Why Choose ChannelUnity for NetSuite
Works with real NetSuite setups: subsidiaries, currencies, locations, custom forms and custom fields.
Orders, deposits, fulfilments, cancellations, refunds and returns, not just order import.
We configure the connection around your account, run test listings and trial orders, and manage a controlled go-live.
Our team monitors your order flow and often resolves issues before you notice them.
Already on NetSuite? Let’s Talk.
Once NetSuite is connected, adding a new marketplace means configuring a new channel, not starting a new integration project. You also get the rest of the ChannelUnity platform: listing templates and rules, dynamic and velocity repricing, and fine-grained shipping settings by marketplace, country and product.
If NetSuite already runs your business and marketplaces are next on your roadmap, book a call with our team. We’ll review your NetSuite setup and target channels, and show you exactly how ChannelUnity fits in.
