POS Integration with Inventory

POS Integration with Inventory

Hello! 

I'm looking for a good option for Point of Sale that integrates with ZOHO Books, including INVENTORY.  Or maybe a different, easier way of doing things.

Currently I am using Square for POS.  While I was able to integrate the transactions (cash and credit card deposits), the inventory portion of the transactions didn't pull over.  I couldn't find a way to do this via the integration.  Did I miss something?  

Is there a POS option that integrates with inventory?  If not, what is the most efficient way to bookkeep this?  Currently, I am posting each deposit's worth of inventory transactions manually as an invoice.  

Thanks!

Tasha
