Hi Ivailo ,
Thanks for your post,
Are you considering adding a feature to sync product availability across multiple sites?
No, sorry. That's nothing we have in mind.
Are you considering a product availability audit feature?
What do you mean? Can you please give us an example?
Is there an option to export the product value that says the product is on hold?
If you're talking about the "stock on hold" field, yes. You can use ATUM Export Pro to do that.
