The first site I surfed had premium as the highest pricing plan with 10 default users. However, the Zoho Books Pricing Comparison document has 'Ultimate" as the highest pricing plan. Though there is no information as regards number of users for the Ultimate Plan. 

ICE Commercial is based in Nigeria, Please advise as to the highest pricing plan for companies in our region. 

ICE Commercial is a Solar Generating Company and presently has 18 Solar Generating Sites in 3 states in Nigeria. We want to track and extract financials for each site. Since the maximum number of reporting tags is 10, does it mean we can only create tags for 10 solar generating sites, or does it mean that we can create tags for the 3 states and create the sites as options under each tag.

In addition, is it possible to link google sheet to Zoho books? In such a way that the site tracking is done on the sheet and Zoho Books is automatically populated with information entered in the sheet.
