[Back](./) # What Should I Consider for Zoho CRM and Zoho Books Synchronisation? Zoho CRM and Zoho Books synchronisation will largely continue to work the same way after migration. However, if you currently sync details such as SIRET or company ID through custom fields, review the mapping because these details are now available as new default fields in Zoho Books. Also review any workflow that creates and sends invoices automatically. In the France edition, invoices must be marked as Open before they can be emailed to customers. If your current sync or automation sends invoices directly from draft status, update the flow to create the invoice, mark it as Open, and then send it.
