I am having some problems with the automation between Zoho CRM and Zoho Books. In my CRM zoho books configuration settings (https://crm.zoho.com/crm/ShowSetup.do?tab=addons&subTab=zohoApps), I have the trigger set to: "Create/Approve/Decline Estimate when a Potential is created/won/lost respectively".

The problem is, when a potential is created, an estimated is automatically generated in Zoho Bookds but automatically marked as "denied". I have discovered that when a potential is created by converting a lead, the estimate in Zoho Books is generated and marked as "draft". Also, Changing the potential's Stage field to Closed Won or Closed Lost does not have any affect on the estimates (does not accept or deny the estimates) in Zoho Books.

Also, the other trigger: "Create/Void Invoice when a Potential is won/lost respectively" does not work at all. 

Why is this? Am I doing something wrong? Can anyone help?
