NetSuite case study
A fast-growing online retail brand ran NetSuite as its core ERP while fulfillment ran through Barrett Distribution Centers — two systems with fundamentally different transaction models that needed to move in step, at more than 20,000 orders a month.
Client context
The client is a rapidly growing online retail brand operating in the U.S., running Oracle NetSuite as its core ERP for order management, purchasing and financial operations, with fulfillment handled by third-party logistics partner Barrett Distribution Centers.
With monthly order volumes exceeding 20,000 transactions and multiple inbound inventory shipments arriving from global suppliers, the business needed a reliable way to keep ERP-driven transactions and warehouse execution in sync — without manual dependencies, and with room to support future warehouse expansion.
The challenge
The obstacle was structural — NetSuite and the warehouse system used fundamentally different transaction models and communication methods, and closing that gap without introducing data mismatches or operational disruption required careful design work, not a quick connector.
Warehouse "Shipment Orders" and "Receipt Confirmations" didn't map directly to NetSuite's Item Fulfillments and Item Receipts — a transformation layer had to translate operational events into ERP-valid transactions.
800–1,000 order transmissions a day during peak cycles, multi-line purchase orders and sequential dependencies where confirmations only arrive after their source transactions exist.
The warehouse ecosystem worked in XML-based messaging and ANSI X12-compatible formats, requiring a framework that could consume, validate and process structured files.
This was never meant to be a single-warehouse solution, so the architecture had to support onboarding additional logistics partners without a redevelopment cycle each time.
The solution delivered
ERP Peers implemented a secure, FTP-based integration framework using structured XML/CSV exchanges to automate transaction synchronization between NetSuite and the warehouse system.
Sales Orders generated in NetSuite are transmitted automatically to the warehouse for fulfillment.
Warehouse shipment confirmations update Item Fulfillments, including tracking numbers and quantities shipped.
Purchase Orders communicate expected inventory, and warehouse receipt confirmations automatically generate Item Receipts in NetSuite.
Built-in checks confirm SKU alignment, validate quantities and prevent duplicates before anything posts.
The framework also runs on dedicated inbound/outbound directories with traceable processing logic for secure, auditable communication, and a centralized error-logging mechanism gives visibility into failed transactions and enables fast reprocessing — built as a reusable framework so it can support additional WMS integrations without duplicating core logic.
Measurable impact
Not projected numbers — this is what changed across the client's own procurement and fulfillment data after go-live.
Order transmission lag (was 4–5 hrs)
Manual processing effort (was ~25 hrs/mo)
Inventory update delay (was up to 8 hrs)
Transaction accuracy (was ~92–94%)
Business impact: fulfillment coordination became system-driven rather than manually managed; finance gained synchronized operational data without reconciliation delays; and the business now has a repeatable integration model ready to support logistics expansion.
Takeaway
This integration framework is now managed by ERP Peers as the client’s NetSuite support partner in the USA, ensuring long-term reliability and scalability. The underlying approach — a structured translation layer between ERP transactions and warehouse execution, with validation and reprocessing built in from day one — applies wherever a NetSuite environment hands off fulfillment to a third-party WMS with its own transaction model, not just this specific integration.
