Dear at Zoho Books, would it be possible for you to have a Field for 'Language' for the Contact Persons under a Company. In CRM and Bigin we could create a Custom Field (Dropdown) for this effect but without any present in Zoho Books we could never sync in between. Unless mistaken in Zoho Books we can't create a Custom Field on Contact level. Please to speak on your possibilities to bring the Field for 'Language' to Books, as standard with the Contact Card (aside, Skype/Department/...) or as possible Custom Field but to reach the Contact Person level aside the only possible Customer-level. Awaiting and thanking you for your understanding and efforts. Regards.
