Does anyone have experience with EazyStock and/or Netstock? Are there any advantages/disadvantages of using one system over the other? Are there any areas of concern/drawbacks? Thanks in advance!

Can I ask why you are looking at inventory management systems outside of Netsuite? What boxes do these check that the netsuite modules do not? I'm curious as to what your final goal is

We use NetStock. We had it with our old ERP system. Integration was seamless. I know our users have been pleased with it.

No experience with EazyStock together with Netsuite. I have however with other ERP system and can say that ES is extremely competent, much better than NS.
