Plans and billing
Essential is US$4.90/month or US$47.04/year, Growth is US$9.90/month or US$95.04/year, and Scale is US$14.90/month or US$143.04/year. Every plan includes a 15-day free trial. Charges are billed in USD through Shopify App Pricing.
Changing or cancelling a plan
Merchants can change plans through Shopify App Pricing without reinstalling MarginShip. To stop future subscription cycles, uninstall MarginShip from Shopify Admin. A charge already generated or pending on a Shopify invoice may remain after uninstalling.
Refund or credit requests
If you believe a charge is duplicate or incorrect, email support@marginship.com with the store domain, charge date, amount and reason. Approved credits or refunds are processed through Shopify's available billing mechanisms.
Before activating a rule
Save the configuration while the rule is inactive, then test the actual shipping methods, themes and discount combinations used by the store. Shopify Checkout is authoritative for final eligibility and discount amounts. The simulator reports an inconclusive result when Shopify does not return enough live delivery evidence.
