Billing for Numana Works is handled through Shopify (Shopify Managed Pricing). To view invoices, change your plan, or update payment details, open your Shopify admin → Settings → Billing, or contact Shopify Support. You're welcome to message us below too — but billing changes can only be made in Shopify.
