I have the impression that you are trying to connect two different systems; an existing one and SCIPIO ERP. If that is the case, you may even consider using a different strategy for this, like implementing Web Services (SOAP, RESTful) in order to connect both systems. Bare in mind that inventory is properly handled within our system so you don’t need to reinvent the wheel here. Additionally, CSV uploading seems to me like a very manual process, although it could be automated as well it’s probably not best suited for that.
However, if what you are trying to achieve is just a data migration, meaning, this will happen once, then yes, CSV upload may be a good solution.
As I mentioned before, we got a plugin that may come very handy, specially for the latter case I pointed out above. Check it out and if you are interested we’d be willing to offer that as a single license (without a full SCIPIO ERP subscription).
