Sagify connects to the currently opened company file that you are logged into. In order for Sagify to run, you must have an active company file opened, and then log into Sagify. If you have multiple company files, Company A, Company B, and Company C, then log into the company file you wish to import orders too.
If keep multiple company files open, then you will need to close them, and only open the one you wan to import into.
