MagmaCharts is being billed monthly. We are a subscription based software-as-a-service.
If you are using MagmaCharts with your Shopify store, we do not handle any payments as Shopify handles all of the payments.
The payment of your MagmaCharts subscription will increase in line with your revenue generated over the past 30 days revenue of your store.
From Dec 1-30, your store revenue is $50,000, you will be charged for $49/pm.
If your store revenue increases to $70,000 in the next 30 days billing cycle, then you will move onto the next pricing tier of $99/pm.
