Hi, I’m a seasoned Shopify developer with extensive experience working with custom themes, JavaScript, and Shopify’s GraphQL Storefront API. I can quickly address the issues on your cart and payment pages. I’ll ensure that the quantity controls work flawlessly, the cart styling aligns with your brand, and the payment page processes orders without errors. I’ll also fix form validation and ensure smooth real-time error handling. Let’s discuss in chat as I have some queries to ask regarding the project to proceed further.

Hello, I read through your requirements, and I completely understand how frustrating these issues can be — especially when cart updates don’t stick and payments stall on checkout. These are high-impact areas for conversion, so fixing them quickly and cleanly is crucial. I have worked on several custom Shopify themes that rely heavily on JavaScript, GraphQL Storefront API, and dynamic cart logic, so I’m very familiar with the exact type of problems you're facing. Here’s how I can help: Cart Page Fixes • Make quantity controls update totals instantly using your current JS/GraphQL flow • Ensure values persist across refreshes • Bring layout, spacing, and components fully back in line with your theme’s design system Payment Page Fixes • Resolve payment-stalling behavior across all existing gateways • Implement real-time form validation with clean, user-friendly error messages • Fully test the checkout flow to ensure reliable transaction completion You’ll also get: • Clean, well-commented code • Fast turnaround with active communication Before I dive in, could you share one quick detail: Are these issues happening only on the live theme or on a duplicate/staging version as well? I am ready to start immediately and get both the cart and payment flow working smoothly. Looking forward to working with you. Regards, Smile Mittal

Yes, I can jump straight into your custom Shopify theme and fix both the cart page and the payment page issues quickly. I have worked on many Shopify builds that rely heavily on JavaScript, custom cart logic, and the Storefront GraphQL API, so debugging cart updates, validation flows, and payment processing is right in my wheelhouse. So I will deliver: > Instant, accurate quantity updates using your current JS/GraphQL structure. > Cart totals that stay correct after refresh + consistent styling (fonts, spacing, buttons). > Fully working payment page with gateways completing reliably. > Real-time form validation with clear, friendly error messaging. > Clean, documented code so you can maintain everything moving forward. I am an experienced freelance Shopify developer, specializing in: > Custom themes with heavy JS logic. > Storefront API (GraphQL) cart & checkout flows. > Fixing broken carts, AJAX updates, dynamic totals, and refresh-state issues. > Debugging payment flow failures + client-side validation. > Fast turnaround on high-priority production fixes. I have handled similar checkout/cart issues for high-traffic DTC brands — usually caused by mismatched Storefront API calls, broken promise chains, stale cart IDs, or validation rules not binding correctly. I can start immediately and deliver fast, precise fixes. Just send theme access and I will begin with a quick diagnostic before patching. Regards.

Warm greetings! I specialize in resolving complex Shopify theme issues, and with over 9 years of hands-on experience in JavaScript-heavy storefronts and GraphQL Storefront API, I can quickly stabilize your cart and payment pages so customers can check out without friction. Here's how I can help: * Fix cart quantity updates so totals refresh instantly and stay accurate * Re-align cart styling to match your theme’s fonts, spacing, and button rules * Restore smooth payment processing across all existing gateways * Add real-time validation with clear, friendly error messages * Document every code change for easy future maintenance Before I begin, could you share whether the payment stalling happens across all gateways or only specific ones? And are your cart scripts split across multiple files or centralized in one module?
