1. Is it possible to use "Zoho Books, Zoho Expense, Zoho Inventory" in tandem to run a multi store, multi warehouse retail company as one organization with 1 GST registration where Zoho is also used as POS?  What would be limitations, if any?

2. What would happen with multiple GST registrations?

I need to know in order to decide if migrating from Intuit from Zoho will work for us or if we would need to develop our own system.
