Some stores prefer a booking or registration action instead of a standard Add to Cart button for Servv services.
Check widget settings
In Shopify admin, open Apps, then open Servv.
Open widget or display settings.
Review whether the Add to Cart button can be hidden or replaced for the widget.
Save any changes.
Check Shopify theme settings
If the button appears on a Shopify product page or theme section, review the theme template and app block settings for that page.
Recommended approach
Use the customer action that best matches the service: booking, registration, checkout, or recording access.
