ERP ecommerce integration that actually stays in sync

ERP ecommerce integration connects your ERP (the system that runs inventory, pricing, customers, and finance) to your online store, so data flows between them automatically. Orders placed in the store create sales orders in the ERP; stock levels, pricing, and fulfillment status flow back to the store. Done right, the ERP stays the single source of truth and nobody re-keys data by hand.

Without integration, someone copies orders by hand, inventory and pricing drift apart, and finance reconciles two systems that never quite agree. Integration removes the manual work, prevents overselling, keeps pricing accurate, and lets you scale order volume without adding headcount. It is usually the difference between an online channel that grows and one that creates back-office chaos.

Our specialty is NetSuite — it is the ERP most of our clients run on, and where we go deepest. The integration patterns (real-time sync, idempotent writes, caching, rate-limit handling) apply to most modern ERPs, so the architecture is portable. If you are on NetSuite, you get our deepest expertise; if you are on another ERP, the same principles apply.

iPaaS platforms like Celigo and Boomi give you pre-built connectors that get live in weeks and are easy to maintain — ideal for standard Shopify, BigCommerce, or Amazon flows. A custom integration (SuiteScript, RESTlets, middleware) is worth it when your logic is non-standard: complex B2B pricing, unusual fulfillment, or rules the off-the-shelf connector cannot express. We help you choose based on your flows, not a default.

Inventory changes in the ERP push out to the store through the integration, and orders reserve stock as they come in. To stay fast and within ERP rate limits, well-built integrations cache and update on change rather than polling constantly, and apply safety-stock buffers so you never oversell during the brief window between a sale and the sync. The right cadence depends on your volume and channels.

Yes — these are among the most common integrations we build. Shopify and BigCommerce have mature iPaaS connectors plus API options; Magento (Adobe Commerce) and WooCommerce integrate via iPaaS or custom flows. We handle orders, inventory, products, pricing, customers, and fulfillment, including B2B scenarios like account pricing and payment terms.

B2B is where integrations get hard: contract pricing, customer-specific catalogs, payment terms, credit limits, and approval workflows all live in the ERP and must stay accurate in the store. We map these explicitly so a B2B buyer sees their negotiated prices and terms, and the ERP enforces the rules. This is a core part of most NetSuite ecommerce integrations we build.

Every order write uses an idempotency key so a network blip never creates a duplicate, and transient or rate-limited failures retry with exponential backoff. Orders that genuinely fail validation are queued and surfaced with clear errors instead of silently dropping. Monitoring and alerting catch issues before they pile up. Reliability is designed in, not bolted on after launch.

A standard iPaaS connection for one channel can be live in a few weeks; a custom or multi-channel integration with deep B2B logic takes longer. The biggest timeline drivers are the number of channels, the complexity of your pricing and fulfillment rules, and data quality in the ERP. After a short discovery, we give you a scoped timeline rather than a generic estimate.

There is no flat price — cost scales with the approach (native, iPaaS, custom, or headless), the number of channels, and how custom your flows are. iPaaS platform fees (Celigo, Boomi) and ERP licensing are separate and paid to those vendors. We do not publish fixed numbers because a realistic figure depends on your scope; after a discovery call we provide a detailed, scoped estimate.
