Hi there, Gyneil.
Welcome to the QuickBooks Community! We understand how this situation might be unexpected, and we're here to help ensure everything is set up correctly so the subscription is managed as intended.
QuickBooks links its subscription billing to the company account, not the individual bookkeeper. When the trial ends, payment information is required to keep the subscription active. If you're logged in as the account manager, QuickBooks might prompt you for banking details, but payment is the company’s responsibility. You can inform the company owner or administrator that they need to update the payment method in QuickBooks to avoid confusion. As the bookkeeper, you’re not responsible for the payment unless you are the account owner or have been explicitly authorized to manage billing.
The company owner should log in and go to Settings > Subscriptions and Billing to add their payment method. If they experience any issues, they can contact QuickBooks Support directly, as billing is tied to their account ownership.
If you have any further questions, feel free to reply to this thread.
