Why Does Amazon + NetSuite Integration Matter for Multichannel Sellers?
When you're selling on Amazon while managing operations in NetSuite, the disconnect between these platforms creates serious operational headaches. Orders flow in from Amazon, but NetSuite doesn't automatically know about them. Inventory updates in NetSuite don't reflect on your Amazon listings. You're stuck manually transferring data between systems, which eats time and introduces errors.
The reality is that most sellers today aren't operating on just one channel. You might be selling on Amazon, your own website, and maybe Walmart or eBay. Each channel needs accurate inventory counts, synchronized pricing, and fast order fulfillment.
When these platforms don't talk to each other properly, you face overselling, manual data entry marathons, and financial reporting that takes days instead of minutes. The good news? Modern NetSuite integration platforms like Flxpoint transform this chaos into streamlined operations.
How Does NetSuite Handle Amazon Drop Shipping Orders?
NetSuite has built-in drop ship features that work well at small scale. When a sales order comes in for an item marked as drop ship, NetSuite automatically creates a purchase order to your preferred vendor. You can configure it to email that purchase order directly. The system keeps your accounting clean by recording revenue and cost of goods sold without putting the item into your inventory.
The Preferred Vendor Limitation

NetSuite's native automation only works with one preferred vendor per item. You set up your item record, designate one vendor as preferred, and that's who gets the purchase order every time. This rigid setup causes problems when you're managing Amazon orders alongside other channels, especially if you work with multiple vendors who carry the same products.
When an Amazon order comes in for an item that three different vendors stock, NetSuite doesn't help you choose the best one. It just sends the purchase order to your preferred vendor, regardless of whether that vendor has the best price, fastest shipping, or even has the item in stock right now. You end up manually reviewing purchase orders and changing vendors, which defeats the purpose of automation.
Manual Tracking and Fulfillment
Once the purchase order goes to your vendor, you're waiting for tracking information. Most vendors don't integrate directly with NetSuite, so someone on your team is copying tracking numbers from vendor emails or portals and pasting them into NetSuite item fulfillment records. Then those tracking numbers need to get back to Amazon so customers receive updates. Each step is manual, time-consuming, and prone to errors.
Where Native NetSuite Falls Short for Amazon Sellers
NetSuite doesn't have a native connection to Amazon. You need some kind of connector to bring Amazon orders into NetSuite and send fulfillment data back. Without this connection, you're downloading order reports from Amazon and manually entering them into NetSuite, or using basic email notifications that don't actually create proper records in your system.
The platform also doesn't handle vendor inventory feeds automatically. If a vendor runs out of stock, NetSuite won't know unless you manually import updated inventory files. This creates overselling risk on Amazon, where out-of-stock listings hurt your seller performance metrics.
What Are the Core Challenges of Managing Amazon Inventory in NetSuite?
Creating and Managing Thousands of Item Records

When you add drop shipping to your operation, SKU counts explode. Instead of managing inventory you physically stock, you're dealing with catalogs from multiple vendors that might include thousands or hundreds of thousands of items. Creating these as item records in NetSuite manually is completely impractical.
Each item record needs specific configuration for drop ship operations. You must mark it as a drop ship item, assign at least one vendor, set pricing, and make sure all the fields align with how NetSuite tracks these items financially. Missing a checkbox or selecting the wrong vendor creates problems down the line when orders process incorrectly or your accounting doesn't balance.
The Rigid Purchase Order Routing Problem
NetSuite's preferred vendor system works against you when managing Amazon alongside other channels. You can't route based on actual business logic like:
- Which vendor has the item in stock right now
- Which vendor offers the best margin on this particular order
- Which vendor is closest to the customer for faster delivery
- Whether splitting the order across vendors makes sense
Instead, NetSuite generates purchase orders to the preferred vendor automatically, forcing you to manually review and change them when that vendor isn't the right choice. At high volume, this becomes a bottleneck that slows down your entire fulfillment operation.
Vendor Connection and Communication Gaps
Every vendor has different requirements for how they want to receive orders and send back information. Some use EDI, others have APIs, many just work with CSV files or emails. NetSuite doesn't have built-in tools to handle this diversity, so connecting each vendor means custom development work—building scripts, API integrations, or EDI connections from scratch.
This custom development is expensive and time-consuming. Worse, it requires ongoing maintenance. When a vendor changes their API, updates their file format, or modifies their requirements, your custom integration breaks and you're paying to fix it. Multiply this across multiple vendors and you're spending significant resources just keeping the connections running.
How Does Automated Order Routing Work Between Amazon and NetSuite?
NetSuite Integrated Platforms which offer dynamic order routing solves the preferred vendor limitation by evaluating multiple factors to choose the best fulfillment source for each order. Instead of blindly sending every purchase order to one vendor, the Flxpoint checks who actually should fulfill based on your business rules.
Intelligent Routing Based on Real Data
Stock Availability First
Flxpoint checks real-time inventory from all your vendors and your own warehouses. If your preferred vendor is out of stock but another vendor has the item available, the order routes to the vendor with inventory. This prevents backorders and keeps your Amazon seller metrics healthy by avoiding delays and cancellations.
Margin Protection Through Cost Comparison
Vendor pricing changes frequently. One vendor might have the best cost this week, but another beats them next week. Automated routing continuously evaluates vendor costs and sends orders to whoever offers the best margin at the moment the order comes in. Over thousands of orders, these margin improvements add up significantly.
Geographic Optimization
When a customer in California orders from your Amazon store, shipping from a vendor in Nevada makes more sense than shipping from a vendor in New York. Routing logic considers vendor locations relative to the customer's address, reducing shipping costs and delivery times while improving the customer experience.
Handling Multi-Line Orders Smartly
Amazon orders often include multiple items. Without smart routing, these orders might split across different vendors unnecessarily, creating multiple shipments and higher shipping costs. Advanced order routing can prioritize keeping the order together when possible, or intelligently split it only when that delivers better overall results.
For example, if one vendor stocks two of the three items ordered and can ship them together, while the third item requires a separate vendor anyway, the system might choose to keep those two items together rather than splitting all three to different vendors.
Real-Time Inventory Synchronization
Automated routing only works if you have accurate, current inventory data from all your vendors. This means connecting to vendor systems to pull inventory updates regularly—sometimes every 15 minutes or every hour, depending on how fast inventory moves.
When inventory syncs in real time, your routing decisions reflect actual availability. You're not routing orders to vendors who ran out of stock an hour ago. The system knows current quantities across all sources and makes routing choices based on what's actually available right now.
Creating the Right Records Automatically
Once routing decides where an order should go, the automation handles creating the proper records in NetSuite. It generates the sales order, creates purchase orders to the correct vendors, and maintains the links between these records. When shipment tracking comes back from vendors, it automatically creates item fulfillment records in NetSuite and sends tracking information back to Amazon for customer updates.
This end-to-end NetSuite automation means orders flow from Amazon through your entire fulfillment process without manual intervention. Your team only gets involved for exceptions or special cases, not for routine order processing.
What's the Best Way to Sync Pricing and Inventory Across Multiple Channels?
Centralized Data Management in NetSuite
NetSuite serves as your system of record—the single source of truth for product data, inventory levels, and pricing. All your other Sales channels, including Amazon, pull from this central data rather than maintaining separate information. When you update a price or inventory quantity in NetSuite, those changes flow out to every connected channel automatically.
This centralized integration approach prevents the chaos of managing each channel separately. You're not logging into Amazon to update prices, then logging into your website to make the same change, then updating another marketplace. One change in NetSuite updates everywhere.
Automated Inventory Updates to Amazon
Through NetSuite ecommerce integration automation, inventory changes trigger immediate updates to your Amazon listings. When someone buys on another channel and NetSuite inventory decreases, Amazon sees the updated quantity within minutes. When you receive new stock from a vendor, the increased quantity pushes to Amazon automatically.
This constant synchronization prevents overselling across channels. The same inventory pool serves all your sales channels, with each sale immediately reducing available quantity everywhere. You're never promising customers inventory that's already committed elsewhere.
Dynamic Pricing Control
Pricing strategies on Amazon often differ from other channels due to competition, fees, or marketplace dynamics. Integration lets you maintain channel-specific pricing rules while managing everything from NetSuite. You might set base pricing in NetSuite, then apply Amazon-specific adjustments automatically—adding a percentage to cover marketplace fees, or reducing prices to match competitors.
These pricing rules execute automatically without manual updates. When costs change in NetSuite, your pricing rules recalculate and push new prices to Amazon. You stay competitive and protect margins without constantly monitoring and adjusting prices manually.
Handling Variant Products and Bundles
Amazon listings often use parent-child relationships for variants—one listing with multiple size or color options. Your NetSuite item records need to map correctly to these Amazon variations so inventory and pricing sync for each specific variant. Integration handles this mapping, connecting individual NetSuite items to the right Amazon variations.
Similarly, if you sell bundles or kits on Amazon, integration can manage the component items in NetSuite. When a bundle sells on Amazon, NetSuite decrements the quantities of all component items, keeping your inventory accurate across channels.
Managing Multiple Vendors with Aggregated Inventory
When multiple vendors carry the same product, NetSuite holds individual vendor records but you need aggregated quantities on Amazon. Integration combines quantities across vendors to show total availability on your Amazon listing, while internally maintaining which vendor has how much. This gives customers accurate availability information while preserving the detail NetSuite needs for order routing.
As vendors update their inventory throughout the day, the integration recalculates your total available quantity and updates Amazon accordingly. This happens automatically in the background, keeping your listings current without manual intervention.
Moving from Manual Processes to Automated Operations
The path from disconnected systems to seamless Amazon NetSuite integration transforms how your business operates. Manual order entry, spreadsheet imports, and constant data synchronization work disappear. Your team focuses on strategic decisions—which vendors to add, how to optimize routing rules, what pricing strategies work best—instead of copying information between systems.
[Webinar] NetSuite + Flxpoint: From Preferred Vendor to Dynamic Order Routing
According to Flxpoint's experience working with NetSuite users, businesses handling drop ship operations struggle most with the limitations of NetSuite's preferred vendor model and the lack of native connections to sales channels like Amazon. These limitations force companies to either accept inefficiency or invest heavily in custom development.
Integration platforms like Flxpoint bridge these gaps by sitting between NetSuite and your sales channels, handling the data translation and process automation that NetSuite doesn't do natively. Orders flow from Amazon through Flxpoint into NetSuite with proper formatting and all required fields. Routing logic in Flxpoint evaluates your vendors and creates purchase orders to the right fulfillment source. Tracking information flows back through the same path to update customers.
