CRM Accounts there is no information about Customer sync?

I have a issue where i want use the same customer in Zoho Subscription after create in CRM. Sync mode is on and at the moment when a account is created I have a new customer in books (the same id in subscription). If i retrieve customer in books i’m able to see the link and ids but my workflow start in CRM where i want to get information across books or subscription but there is no ID related in CRM. There is way to get or use the same customer and prevent duplication if the first read is in CRM.
