ABCheck is a Shopify app developed by Nextools that allows merchants to run real A/B tests on payment methods directly at checkout. It is the only Shopify app that lets you scientifically test which payment method drives more conversions or higher average order value (AOV).
Instead of guessing whether showing Credit Card or Cash on Delivery first will convert better, ABCheck gives you hard data, split traffic between two payment method variations and measure the results.
Your checkout payment options have a direct impact on how many customers complete their purchase. The wrong payment method shown at the wrong time can cause cart abandonment. ABCheck removes the guesswork by letting you:
-
Test different payment method layouts and ordering
-
Measure checkout conversion rate across variations
-
Track Average Order Value (AOV) per variation
-
Automatically stop experiments after a set threshold
-
Export and re-import experiment configurations
Who is ABCheck for?
ABCheck is built for Shopify merchants who want data-driven control over their checkout experience. It is especially useful for stores that:
-
Offer multiple payment methods (credit card, COD, digital wallets, BNPL, etc.)
-
Want to optimize checkout conversion without making risky all-in changes
-
Need to understand which payment options their specific customer base prefers
