BigCommerce + NetSuite Integration

The BigCommerce + NetSuite Problem

You chose BigCommerce for its flexibility. You run NetSuite for your back office. Now you need them to talk to each other, and the native connector isn't cutting it.

We hear this constantly from mid-market eCommerce companies. The out-of-box integration tools either lack features you need, break under high order volume, or require so much manual intervention they defeat the purpose.

How Our Integration Works

We've connected BigCommerce to NetSuite for brands doing anywhere from 100 to 10,000+ orders per day. The architecture scales, but the fundamentals stay the same.

Orders: BigCommerce → NetSuite

When a customer checks out on BigCommerce, a Sales Order appears in NetSuite within minutes. Not hours—minutes. The order includes:

• Customer record (created or matched to existing)
• Line items with correct NetSuite item records
• Shipping method mapped to your carriers
• Payment captured or payment method reference
• Tax calculated by BigCommerce or recalculated in NetSuite (your choice)
• Discount and promotion details
• Custom fields you've added to checkout

We handle guest checkouts differently than registered customers. Guests either create minimal customer records or consolidate under a "Web Sales" catch-all depending on your preference.

What about B2B orders?

If you're running BigCommerce B2B Edition, the integration gets more interesting. We sync customer-specific pricing, payment terms, purchase order numbers, and approval workflows. Your sales reps can see web orders alongside phone/email orders in a single NetSuite view.

Inventory: NetSuite → BigCommerce

This is where most integrations fail under pressure. Your warehouse receives 500 units, and BigCommerce still shows "out of stock" for an hour. Or worse—you oversell because the sync is too slow.

We build inventory sync to update BigCommerce within minutes of NetSuite changes. For high-velocity SKUs, we can push updates in near real-time. The system handles:

• Multi-location inventory: Sum across warehouses or show specific location availability
• Available vs. on-hand: Committed inventory, backorders, safety stock rules
• Bundle/kit availability: Calculate based on component availability
• Preorder and backorder logic: Different messaging based on stock status

Products: NetSuite → BigCommerce

Creating products in two systems is a waste of time. We make NetSuite the master:

• Item records push to BigCommerce with descriptions, images, pricing
• Categories map to BigCommerce categories
• Custom fields translate to product metafields
• Variant/option structures sync for matrix items
• Price lists for customer groups (B2B)

Changes in NetSuite propagate automatically. Your merchandising team works in one place.

Fulfillment: NetSuite → BigCommerce

When you ship an order in NetSuite (or your 3PL confirms shipment), BigCommerce gets the update:

• Order status changes to shipped
• Tracking number appears in customer's account
• Shipping confirmation email triggers

No manual status updates. No customer service tickets asking "where's my order?"

Technical Architecture

Most BigCommerce-NetSuite integrations we build use one of three patterns:

Pattern 1: Celigo iPaaS

Best for: Companies already using Celigo, need low-code management, want vendor support.

Celigo has pre-built BigCommerce flows we customize to your requirements. Your team can monitor and make minor adjustments without developer help.

Pattern 2: Custom Middleware

Best for: High-volume stores, complex logic, need full control.

We build a Node.js or Python service that handles the integration logic. Runs on AWS, GCP, or your infrastructure. More development effort upfront, lower ongoing costs, complete flexibility.

Pattern 3: n8n Workflows

Best for: Mid-volume stores, budget-conscious, want visual workflow editor.

n8n gives you iPaaS-like functionality at a fraction of the cost. Self-hosted or cloud. Good middle ground between Celigo and custom code.

What Makes This Hard

The APIs are documented. The data models are known. So why do BigCommerce-NetSuite integrations fail?

Volume spikes: Black Friday hits and your integration queues back up. Orders sync hours late. Inventory gets out of sync. We design for peak load, not average load.

Edge cases: Guest checkout with a gift card paying partial balance and applying a coupon to a backordered item that ships from two warehouses. Real orders look like this. Your integration needs to handle them.

Data quality: Customer entered "123 Main St" on BigCommerce but NetSuite has "123 Main Street" for an existing record. Do you create a duplicate? Merge? Match on email instead? These decisions matter.

Ongoing changes: BigCommerce adds new features. NetSuite releases updates. Your business changes processes. The integration needs maintenance.

Realistic Timelines and Costs

Standard implementation: 4-6 weeks, $25,000-$50,000

Includes order sync, inventory sync, basic product sync, and fulfillment updates. Standard mapping, reasonable volume.

Complex implementation: 8-12 weeks, $50,000-$100,000

Multi-subsidiary, B2B pricing, custom checkout fields, 3PL integration, high volume optimization, historical data migration.

Ongoing support: $1,000-$3,000/month

Monitoring, error handling, minor adjustments, version updates.

These are ballpark ranges. We quote fixed-price after understanding your specific situation.

Questions We Often Answer

Can we start with order sync and add inventory later?

Yes. Many clients phase the implementation. Get orders flowing first, stabilize, then add inventory sync. It's a reasonable approach if budget is constrained.

What if we switch 3PLs or add a new warehouse?

The integration adapts. Warehouse configuration changes in NetSuite propagate to how we calculate and push inventory. Shouldn't require rebuilding the integration.

How do you handle BigCommerce multi-storefront?

Multiple BigCommerce storefronts can connect to one NetSuite account. We route orders to different subsidiaries or channels as needed. Inventory can be shared or store-specific.

What about returns and refunds?

Returns initiated in either system can sync to the other. RMA creation, refund processing, inventory put-away—all can be automated or semi-automated depending on your workflow.

Getting Started

If you're evaluating BigCommerce-NetSuite integration, start with these questions:

1. How many orders per day at peak?
2. How many SKUs and warehouses?
3. B2C only, or B2B included?
4. What's your current tech stack (any existing iPaaS)?
5. What's broken or slow in your current process?

Bring those answers to a call with us and we'll tell you honestly what it takes to connect these systems properly.
