FAQ
Do I need to contact you before ordering?
Yes. Please send your store URL, issue details, and screenshots or a screen recording. I will confirm the correct package before you order.
What information do you need to start?
I need your Shopify store URL, a clear explanation of the problem, the expected result, your theme name, and Shopify collaborator access when required.
Can you work on any Shopify theme?
Yes, I work with Dawn, Shopify Theme Store themes, properly licensed premium themes, and custom Shopify 2.0 themes. I do not work with illegally copied themes.
Can you fix Shopify app problems?
I can fix theme-and-app conflicts, app integrations, storefront app issues, and custom app problems. Backend app issues require an initial code review.
Do you fix cart, variant and product-page issues?
Yes. I can diagnose cart drawers, add-to-cart problems, variant selectors, product forms, collection filters, dynamic pricing displays, and related JavaScript or Liquid issues.
Can you fix Shopify Checkout problems?
Checkout customization depends on the Shopify plan and the type of issue. Shopify Plus, Checkout UI Extensions, Functions, and third-party checkout work require review before ordering.
Can you guarantee a specific PageSpeed score?
No responsible developer can guarantee one score because apps, tracking scripts, themes, servers and third-party services affect performance. I can diagnose and improve code-related performance issues.
Will you provide support after delivery?
Yes. I provide support for issues directly related to the delivered work. New features or unrelated changes require a separate order.
Can you make urgent same-day repairs?
Sometimes. Send the issue before ordering so I can check availability and determine whether same-day delivery is realistic.
