About this gig
Is your Shopify Add to Cart button not working, cart drawer broken, checkout button failing, or product page behaving incorrectly? These issues can frustrate customers and stop completed purchases.
I will diagnose the actual cause of your Shopify problem, fix it properly, and test the affected functionality so your customers can shop smoothly again.
I can help you fix
- Add to Cart button issues
- Shopify cart & cart drawer errors
- Checkout button problems
- Product page functionality issues
- Wrong variants, prices or quantities in cart
- Liquid code & JavaScript errors
- Shopify theme bugs and conflicts
- Mobile responsiveness problems

- Broken buttons, sections or features
- Problems caused by theme updates/custom code
I don't just apply a random quick fix. I will identify what's causing the issue, repair the affected area, and test the customer journey from product cart checkout where relevant.
My goal is simple: remove the technical problem that's disrupting your store and leave you with a cleaner, more reliable shopping experience.
Please message me with your store issue before ordering if you're unsure which package fits.

FAQ
What Shopify problems can you fix?
I can fix cart, Add to Cart, checkout button, product page, Liquid code, theme, mobile, app conflict, and other store functionality issues.
What do you need from me to get started?
Please send your Shopify store URL, a clear description of the problem, screenshots or a short video if possible, and when the issue started.
Will you need access to my Shopify store?
For most fixes, yes. I may need Shopify collaborator access to safely inspect the theme, code, apps, and settings causing the problem.
My Add to Cart button is not working. Can you fix it?
Yes. I can investigate theme code, JavaScript, product settings, variants, apps, and other possible causes, then fix the identified issue.
Can you fix a broken Shopify cart or cart drawer?
Yes. I can troubleshoot carts that won't open, update incorrectly, show wrong quantities, fail to remove products, or behave differently on mobile.
Can you fix Shopify checkout problems?
I can diagnose and fix checkout-related issues that are within the store/theme/settings I can access. Please message me first with the exact checkout problem.
Can you fix problems caused by a Shopify app?
Yes. I can investigate theme and app conflicts and fix compatible code-related issues. If the problem is controlled entirely by a third-party app, I'll explain the best next step.
Will you test the store after fixing the issue?
Yes. After the repair, I will test the affected functionality and, where relevant, check the flow from product page → cart → checkout.
Can you fix Shopify mobile-only problems?
Yes. If your cart, buttons, product page, sections, or other features work on desktop but break on mobile, I can troubleshoot and fix them.
What if I don't know what is causing the problem?
That's completely fine. Send me what you're experiencing, where it happens, and any screenshots/video. I can investigate the cause before applying the appropriate fix.
