You need to log in to QuickBooks Online (QBO) as an administrator (primary or company) so you'll be given the option to resubscribe, obidur.
First, may I know what subscription you're referring to? Are you referring to a QuickBooks Online subscription or other integrated services?
For renewing your QBO subscription, you'll be prompted to resubscribe as soon as you sign in to your account. Otherwise, you can follow these steps to get to the subscription page:

- Log in to QBO as the primary admin, then go to Settings.
- Click Subscriptions and billing.
- For your QuickBooks plan, click Resubscribe and enter updated billing info.
- Enter the important Payment information and Billing address.
- Select Resubscribe.
I've also included this article for the next steps after your QBO subscription renewal: Resubscribe to QuickBooks Online.
However, if you're referring to other integrated services in QBO, such as QuickBooks Payments and QuickBooks Payroll, just click Resubscribe in the Subscriptions and billing.
Come back to this post if you have other questions or concerns.
