Step 4: QA Before Launch

Subscription pricing involves multiple systems, so thorough QA is required.

• Correct subscription price shows for each variant
• Subscription discount updates properly
• Billing interval (monthly, quarterly, etc.) remains unchanged
• Checkout reflects correct subscription price
• Order in Shopify shows correct subscription pricing

We recommend manually checking each test group using preview links before launching.

How TestSignal Handles Stay.AI Pricing

When integrated:

• TestSignal assigns visitors to a test group
• TestSignal updates the subscription pricing via Stay.AI API
• Stay.AI renders the correct subscription price on the product page
• Checkout and recurring billing follow the assigned variant pricing

This ensures subscription price tests remain statistically clean and technically accurate.

Custom Subscription UI?

If your theme uses a custom Stay.AI widget implementation:

• Ensure price elements update dynamically
• Confirm no hardcoded pricing exists in the theme
• Work with your dev team if pricing does not reflect test variants

TestSignal support team can assist if custom theme adjustments are required.
