Just figured i'd do another ask incase theres a different audience today, anyone have any opinions on Celigo or Boomi?

Havent tried Celigo but I find Boomi satisfying, at least for me. Easy to use and has good available sources.

I've used Boomi and like it because it's a tool that can handle multiple integrations, both with and without NetSuite - Haven't looked at Celigo.

how easy is it to interact with NS? say i compare stock levels in NS and with another WMS can I easily create a NS record with discrepencies?

I've used Boomi and I do find its a good tool.
