A $78M building materials distributor eliminated all manual order re-entry, cut fulfillment time by 60%, and scaled online orders from 100/day to 300/day by integrating Shopify Plus with Oracle NetSuite. Inventory accuracy hit 99.8%. Order errors dropped from 4% to 0.2%.

The Challenge

After 30 years of phone and field sales, this distributor launched a Shopify Plus store expecting modest supplemental volume. Within six months they were processing 80-100 online orders per day -- and the manual process was breaking.

A customer service rep re-keyed every Shopify order into NetSuite. Then updated order status back in Shopify. Then manually entered tracking numbers when orders shipped. This consumed 2-3 hours every morning before the warehouse could start picking.

Inventory updated once daily, so customers ordered items that were out of stock -- requiring apology calls and alternatives. Re-keying introduced errors in about 4% of orders: wrong quantities, wrong SKUs, wrong addresses. At 100 orders per day, that meant 4-5 problem orders daily. More than a full FTE worth of labor went to managing the gap between the two systems.

The Solution

We built a real-time integration between Shopify Plus and NetSuite using SuiteCloud APIs and Shopify REST/Webhooks, with middleware handling data transformation and retry logic.

Automatic Order Creation: Shopify orders create NetSuite sales orders within two minutes. Orders placed at 2 AM are ready for picking when the warehouse opens.

Real-Time Inventory Sync: NetSuite levels push to Shopify every 15 minutes. Allocated inventory reflects immediately. Customers cannot order what is not available.

Shipment and Tracking Automation: Tracking numbers entered in NetSuite post to Shopify automatically. Customers get shipping notifications without anyone touching Shopify.

Customer Data Sync: New Shopify accounts create NetSuite customers automatically. Order history visible in both systems.

Product Information Management: Descriptions, images, and pricing mastered in NetSuite, published to Shopify. Marketing updates products in one place.

Implementation

Weeks 1-2: Field mapping, business rules documentation, SKU cross-reference table. Defined handling for partial shipments, backorders, and returns.

Weeks 3-5: Development and sandbox testing. Thousands of test orders validated against every scenario.

Week 6: Shadow mode -- integration ran alongside manual entry, results compared. Caught three unanticipated edge cases.

Weeks 7-8: Phased go-live: inventory sync first (lowest risk), then order automation, then shipping updates. Fully automated by end of week 8.
