BrokenRubik builds and runs Shopify–NetSuite integrations. We are an independent consultancy that has worked only in NetSuite since 2017, a Celigo Standard Partner, and we build Shopify stores too, so the storefront and the ERP side are one team's job.
We use one of four approaches. Celigo's Shopify–NetSuite integration app, extended with custom flows, fits most stores whose order process is close to standard. Oracle's NetSuite Connector fits simpler single-store setups. Boomi fits when it already runs your other integrations: we connected Shopify, NetSuite and Blue Box this way for Clean Simple Eats (read the case study). A custom integration with SuiteScript and the Shopify Admin API fits business rules no template expresses.
What syncs: Shopify orders become NetSuite sales orders with customer, items, prices, discounts, tax and shipping; fulfillments and tracking numbers go back to Shopify; inventory flows from NetSuite by location; cancellations, refunds and returns post to NetSuite so finance can reconcile.
New builds, migrations and repairs of an existing integration are a fixed price. Support after go-live is a monthly retainer. You get a written quote after a short review.
