When two companies work using Zoho Books, and one is vandor , it would be great that vandor can just chose and sync created invoices to his clients zoho books acount. In that way client account will automatily recive those invoice as bills / expenses and vandor will be sure that all invoice are surely sent.

So both companies would in more easier and secure way work, without need of manually adding those invoice in Zoho Books or scaning them using document scaning feature.
