I'd be glad to help you if you wish to resubscribe to QuickBooks Online.
Sign in to your QuickBooks Online company.
Choose Settings ⚙ at the top.
Under Your Company, select Company Settings.
Click Billing & Subscription, then Resubscribe.
Enter the updated billing information and then click Subscribe.
Log out, then log in again to your account. Go back to the Billing & Subscription section, then check the Next charge date. If it's a date in the past, contact support to prevent back-billed charges from occurring.
