Although you cannot renew a subscription manually, there are two alternatives available
Upgrading your plan
To upgrade your plan, go to the Subscription section and click on Change my plan.
Next, you can choose the plan that you wish to upgrade to:
Enable Credits over quota
Since January 8, 2025, credits over quota must be manually enabled during the checkout process when purchasing a new plan. Before that date, credits over quota were enabled by default for all subscriptions. No changes have been made to existing subscriptions.
Access to Credits over quota must be enabled during the checkout process when purchasing a new subscription or upgrading/downgrading your plan. However, you can also enable or disable this option later from the Subscription section of your account.
To enable this option from the Subscription section, you can click on the Edit option inside the Credits over quota section. Then, toggle the option to Allow credits over quota in the new pop-up window.
You can also enter the maximum number of Search Credits over quota per month or Verification Credits over quota per month you wish to use.
Credits over quota are billed once you reach the billing threshold indicated on your Subscription page (monthly cost of your plan) or when the plan resets at the end of the yearly or monthly period, whichever comes first.
They'll be included as an extra in your renewal invoice or as a standalone invoice if you have cancelled your yearly plan.
