When you first sign up for Zapier, you’ll start a free 14-day premium trial. Any change to your Zapier plan is immediate, and your usage does not reset when your plan changes. For example, if you downgrade during your plan month, Zaps that don't comply with your new plan (e.g. if the Zap is using a Premium app) will be turned off. You can upgrade, downgrade, or cancel your Zapier plan at any time.
If you’re on a Zapier for Teams plan, you must be the team owner to be able to change the plan.
