It would EXTREMELY helpful and practical if the attachments added to an invoice via Zoho Finance in CRM synced with the invoice updates in Zoho Books.  Currently, attachments to an invoice updated in CRM DO NOT appear as attachments when viewing the same invoice in Zoho Books.  I was informed by support that this can only be done by manually attaching the documents in both applications. 

Please add this feature as soon as possible and allow attachments to an invoice to sync between CRM and Books. 

Thanks,
