iClosed provides a 7-day trial for both Startup and Business plans, and you will be charged only after the end of the trial period (unless you upgrade to higher tier).

Once the trial ends, subscription will start, and the renewal date will be 30 days after the subscription has started.

This means, that subscription start date will not be the day when you signed up for trial, but when you made the payment and officially started subscription.

Upgrading from Startup Free Trial to Business plan (or downgrading) is allowed, but the upgrade/downgrade will be triggered automatically, and end free trial immediately.

This means that your credit card will be charged for the newly selected plan, and your subscription start date will become the day of the upgrade.

Yes, you can add as many extra user seats as you would like, or to remove seats while you're on free trial, but your credit card will be charged for the exact number of seats active at the end of the 7-day free trial and start of billing cycle.

You are available to change the billing cycle during the 7-day free trial, but as soon as the free trial ends, your credit card will be charged according to the billing cycle subscription plan price.
