Hi MissMel,
I appreciate your reaching out. I can assure you that the billing for your MYOB subscription is accurate. Your current MYOB AccountRight Premier subscription includes multiple online files. You can view the breakdown of these charges when you go to manage your MYOB subscription. Please remember, if you have a bonus file included in your current subscription, getting an additional subscription won't give you another bonus file.
For further details about having two files per subscription, I suggest contacting our sales team. You can reach them at this link. They can provide precise information and help you understand how to get the most out of your MYOB subscriptions.
Feel free to post again anytime you require further assistance.
Kind regards,
Shella
