Billing
Price per site: Free runs forever, Starter is $24 a month, Pro $49. Starter and Pro go through Stripe, where invoices, receipts and your card live.
Free runs one change a month with undo, a monthly snapshot and the summary email. Starter is $24 a month or $240 a year. Pro is $49 a month or $490 a year. Prices are per site: a second business's site on your account is priced on its own, and a store connected to a site as a second connection is not a second site.
Upgrading opens a Stripe checkout page. Your new limits apply to every site on your account as soon as Stripe confirms the payment.
A Shopify store that installs Camello from the Shopify App Store, once Camello is listed there, pays the same prices through Shopify instead: its plan is chosen and changed in the Shopify admin, and that plan covers the whole site the store belongs to. A store connected from Camello's Connections page pays through Stripe like any other site.
Each plan has a monthly budget for the measurements Camello buys on your behalf. When a site reaches it, the remaining checks pause until the next month and you get one email.
Invoices, receipts and your card live in the Stripe billing portal, reachable from the plan page.
