Hi Stanstrata,
Thanks for posting.
Absolutely, you don't have to spend long hours on the phone for support. The process of adding another company file can be a bit tricky, as it involves reviewing your current subscription. To save time, you can create a support ticket through My Account (myaccount.myob.com) or contact our sales team via this link. They can provide detailed information and help you understand which MYOB product subscription is best if the third file doesn't require payroll.
Feel free to post again anytime you require further assistance.
Kind regards,
Shella
