Subscriptions are processed through Shopify Billing (for EasyRoutes for Shopify) or Stripe (for EasyRoutes for Web). After your 14-day trial, app charges run on a 30-day subscription cycle that is independent from Shopify’s invoice cycle. When you add or remove driver seats during a cycle, we prorate charges/credits automatically. SMS delivery notifications are usage-based and draw from a separate balance when enabled.
