Custom integrations are cheap to build and expensive to own. Two years on, the person who wrote it has left and nobody wants to touch the thing keeping orders flowing into the ERP.
Celigo replaces that with maintained connectors, and it is particularly strong where NetSuite is the centre of gravity. We configure the flows, handle the field mapping properly, and set up error handling so a failed sync is visible. Prebuilt does not mean no work. The mapping between how your commerce platform thinks about an order and how your ERP does is where the effort goes.
