What are the options to connect to/sync NetSuite with Shopify? Farapp, Celigo, what else?

Folio3, Dell Boomi and jitterbit

As of now, even though we have thousands of items, we'll only sell less than 10. Is there any cost-effective option? What are our options if we have to do it manually? Export SOs from Shopify, export the shipments, import the invoice to Shopify and upload the inventory advice to Shopify? Are these all possible?

Go for the custom integration development.

Manual is definitely an option for small volume of orders. You can do csv export and import. They are definitely possible in Shopify. Anything you can't find natively could be available in a plugin.

Shopify has a pretty decent API. Building base flows would be fairly easy. I've done some of them

Thanks everyone! Let me just clarify something about the custom integration. Is that a recommendation even if we have thousands of items to sell on Shopify? Or only because we have few items anyway at the moment?

Custom integration can map to your business processes without additional scripts/customization

Money and ability to customize. Celigo and the like are not great at anything deviating from very basic flow. They don't handle multi-location, POS or other processes very well.

These are great inputs! Thanks everyone!

Do check out Celigo, especially the latest version. Especially when paired with the underlying integrator.io platform, it is extremely customizable. There's a reason several thousand NetSuite customers are using it... far more than anyone else. I'm biased but do take a look.

Is there a difference between stand-alone Celigo and one with integrator.io?

The Celigo Shopify-NetSuite integration app is built on the integrator.io platform. The vast vast majority of Shopify integration functionality is built natively in the integration with robust customization options. Additional customizations can be done with additional flows with integrator.io
