ParityTest runs price A/B tests on your storefront using Shopify Discount Functions. Each price group in a test is shown with the same discount treatment, so results reflect actual price response, not a difference in whether one group saw a discount and the other didn't. Results are reported as profit per visitor alongside conversion rate, since a lower price with a higher conversion rate can still perform worse on profit. Works on any Shopify plan. Shopify Plus is not required.

• Run price A/B tests without introducing a discount-perception bias
• See profit per visitor for every test group, not just conversion rate
• Available on every Shopify plan, no Shopify Plus required
• Built-in support for GDPR data access and deletion requests
