Currently more and more of Zoho Accounting enhancements are being releases as "Enterprise stand alone version - not "Enterprise Zoho one Version." I just found out that the new "Purchase Returns" module is this way. Zoho needs to re-evaluate this. This is beginning to be a problem. I understand that you can't continue to expand the capabilities of your software and keep it financially within the constraints of the Zoho One subscription. To not have a way to add them as an upgrade for Zoho one users is wrong. I asked tech support how we can get these new enhancements; They said that I would have to delete Zoho Inventory from Zoho One and then pay full subscription for Zoho Enterprise StandAlone. To make someone now pay full price subscription for software when we already have access to "Most of the  program" is a wrong solution.
