When you sign up for a Lasso subscription, you pay per-site.
When you install Lasso on a WordPress site and use your license key to activate it, you're adding a site to your plan and that could activate a billing upgrade to your per-site costs.
Adding Staging Sites to Lasso
Note: Annual/yearly plans get staging sites added to your license for free! Make sure to reach us at [email protected] to let us know about extra sites you add so you don't get any additional charges.
If you add an install to your Lasso license, it'll start off deactivated in your account.
If you want, you can then activate it by flipping the Active toggle to the right, turning it green. A popup will warn you that you're about to increase your bill.
