NetSuite Integration & Implementation

Why Custom NetSuite Integration Matters

NetSuite is the ERP of choice for growing e-commerce brands. It handles financials, inventory, order management, and procurement in a single platform. But connecting it to your storefront is where most teams struggle.

Off-the-shelf connectors (Celigo, FarApp, Pipe17) work for basic setups. They fall apart when your business has custom workflows, multi-location inventory, complex pricing, or volume that exceeds middleware rate limits. That's where custom integration pays for itself.

Core Data Flows

Order Lifecycle

When a customer places an order on Shopify, our integration:

1. Receives the order via webhook (sub-second latency)
2. Maps Shopify line items to NetSuite items using SKU or custom identifiers
3. Creates a sales order in NetSuite with correct subsidiary, location, and pricing
4. Handles tax mapping between Shopify tax lines and NetSuite tax codes
5. Monitors fulfillment events and updates Shopify tracking automatically
6. Processes refunds and creates corresponding credit memos

Every step is idempotent. Processing the same order twice produces the same result, eliminating duplicate records during retries.

Inventory Synchronization

Inventory flows from NetSuite to Shopify:

• Quantity available calculated from NetSuite item availability (on-hand minus committed)
• Multi-location inventory mapped to Shopify locations
• Safety stock thresholds respected
• Updates pushed on item save events or on a configurable schedule
• Delta-based updates (only changed items) to minimize API usage

Financial Reconciliation

The most underestimated integration surface. We automate:

• Shopify payout matching against NetSuite customer deposits
• Payment processing fee journal entries
• Gift card liability tracking
• Multi-currency transaction handling
• End-of-month reconciliation reports

Architecture

All integrations follow our standard architecture: event-driven with durable message queues. Orders, inventory updates, and financial events flow through Kafka (or SQS for simpler setups), ensuring no data is lost if either system is temporarily unavailable.

Monitoring is built in from day one. Every sync event is logged, every error is alerted, and a reconciliation dashboard shows the real-time state of data across both systems.
