Hello, Maccasathessle :waving_hand:Welcome to the Community. If you wish to add an accountant to your Online subscription you would do this in manage users, please see link. that will show you step by step instructions on how to.
If using the Self-employed product you would go into the gear icon, then Accountant, this will then allow you to invite your accountant. If you do not have this as an option as not all subscriptions do on Self-employed .e.g if your subscription is through Apple/google adding an accountant won't be a feature. You can cancel your subscription with them and we can migrate the billing to us so that you have this feature. Becky
