Implementing NetSuite can be a game-changer for eCommerce companies looking to scale—but it’s not without its challenges. NetSuite’s flexibility and depth make it an ideal ERP for fast-growing online retailers, but success depends on how well it’s planned and executed.
Here are 8 of the most common mistakes companies make during a NetSuite implementation for eCommerce—and how to avoid them.
1. Not Defining a Clear Fulfillment Strategy
Many eCommerce businesses use a mix of in-house fulfillment, dropshipping, 3PLs, and marketplaces like Amazon. NetSuite can support all of these, but only if configured properly. Failing to map out how each fulfillment method works in practice leads to order routing errors and inventory headaches.
Tip: Document every fulfillment scenario before you begin implementation.
2. Overcomplicating the Integration Stack
NetSuite often needs to integrate with Shopify, WooCommerce, Amazon, ShipStation, or 3PL systems. A common mistake is trying to integrate everything at once or relying on custom code when pre-built connectors (like Celigo or Workato) would suffice.
Tip: Prioritize mission-critical integrations first and use scalable iPaaS tools when possible.
3. Ignoring SKU and Item Data Hygiene
eCommerce companies often have bloated SKU catalogs with inconsistent naming, missing weights, or outdated variants. Poor data leads to sync failures, shipping issues, and inventory mismatches.
Tip: Clean and standardize your product data before migrating it into NetSuite.
4. Neglecting Real-Time Inventory Visibility
NetSuite offers real-time inventory tracking—but only if you configure locations, bins, and reorder points correctly. Many retailers go live without understanding how NetSuite handles committed vs. available inventory, leading to stockouts or overselling.
Tip: Plan your inventory strategy across warehouses, FBA, and 3PLs during the design phase.
5. Forgetting to Automate Taxes and Shipping
Trying to handle tax rates and shipping charges manually in NetSuite is a recipe for errors. Many eCommerce companies skip integrations with Avalara, ShipStation, or EasyPost—only to circle back later.
Tip: Automate these components early in the project to streamline checkout and fulfillment.
6. Underestimating the Complexity of Returns and RMA
Returns and refunds are a critical part of eCommerce, but NetSuite’s return process needs to be set up correctly to avoid inventory mismatches and customer service delays.
Tip: Configure Return Authorization and RMA workflows to reflect your actual return policy and logistics.
7. Skipping Dashboard and Reporting Setup
Out of the box, NetSuite dashboards are generic. Without custom saved searches and KPIs tailored to your eCommerce business, you’ll miss out on insights into customer lifetime value, best-selling products, or channel profitability.
Tip: Set up role-specific dashboards for marketing, finance, fulfillment, and customer service.
8. Neglecting Training and Change Management
ERP implementations often fail not because of the software—but because users weren’t trained. eCommerce teams move fast, and adopting a structured platform like NetSuite can feel restrictive at first.
Tip: Invest in training sessions, documentation, and internal champions to drive adoption across your team.
Final Thoughts
A successful NetSuite implementation for eCommerce companies isn’t just about going live—it’s about setting up scalable processes that grow with your business. Avoiding these common pitfalls can mean the difference between months of frustration and a smooth, revenue-driving ERP system.
Whether you’re migrating from QuickBooks or replacing multiple disconnected tools, working with an experienced NetSuite partner can help you implement faster and smarter.
