Hi anu_p,
Thank you for your post. I'd like to extend you a warm welcome to the Community forum. I hope you find it a valuable resource.
An Owner user is typically the primary/billing contact on an account. To change or update an AccountRight Live owner, the primary contact or the current AccountRight Live owner can get in touch with us to update that user access. I'll be reaching out to you via private message to gather additional information. In terms of inviting your accountant to your AccountRight file, kindly refer to this Help article, which has detailed information to assist with this.
Please keep an eye on your Community forum inbox, and we'll continue to address and discuss your concern through that channel.
Cheers,
Princess
