You can upgrade your account at any point.
Although, we are currently working on the upgrade feature. Which means, right now if you wish to upgrade, please contact us at Avery@modash.io.
When upgrading from lower tier to higher one, without changing billing interval (monthly or annually) your subscription plan will change immediately. You will be automatically charged on your next payment date. After that, you’ll be billled normally each month.
When switching from monthly payments to annually one, your subscription plan will change automatically and you will be charged for the entire year.
