You may easily upgrade/downgrade your Ahrefs subscription anytime from 'Account settings':
Where you need to navigate to 'Billing menu' and choose 'Change plan' button:
Or 'Pricing' page:
When upgrading your plan to a higher package, changes take effect instantly.
If you subscribed with us prior to Jan 2020, - you are issued a pro-rated refund for your previous subscription and charged for a new one. Do note that it won't necessarily be the full charge - the charge for a new plan will cover remaining billing period that doesn't change after upgrade.
If you Subscribed after Jan 2020 - no refund is issued and the remaining amount of charge is used as a part of your payment for the higher plan. You're also charged a new partial payment to cover the missing difference.
Please, mind that your billing cycle dates do not change.
When downgrading your plan, no refund is issued. Changes take effect at the end of a paid period (you remain on your current plan till your next billing date).
This procedure will work for switching from monthly to monthly, as well as from yearly to yearly subscriptions.
