Your Plan and Billing
Free vs. paid, and how to upgrade
Checking your plan
Go to Configuration -> Site Plan to see whether you are on Free or Paid, and exactly which apps that unlocks or locks for your site.
Upgrading
Click Upgrade and enter a card to start a paid subscription -- new sites typically start with a free trial period before the first real charge. Manage your card, view invoices, or cancel at any time from the same Site Plan page, which hands off to a secure billing portal for those actions.
If a payment fails
Your Shop Space automatically retries a failed renewal payment a few times over the following days -- your site stays on the paid plan during that window, so a single missed charge does not immediately lock you out. You will get an email if it happens; update your card from Site Plan to resolve it.
