HOW IS INVENTORY MANAGED WITH ZOHO INVOICE AND CRM INTEGRATION

Hi , since Zoho Invoice and Zoho CRM is now integrated, I need to know how does it work when I create an invoice in Zoho invoice, and then fetch it with zoho crm to an specific account. Since Zoho invoice does not handle inventory, and CRM does. will the export feature will affect the products inventory?
Also when I create a Credit Note on Zoho invoice and then sync with Z.CRM , will it affect the products inventory?

How does this work.

Thank you,
