Shopify theme · cart · mobile bug fixes

Shopify cart, theme, and mobile bugs fixed before they cost you more sales.

I run a fixed-scope Shopify bug fix for broken cart drawers, product page issues, mobile layout problems, app conflicts, and theme bugs. You get screenshots, findings, small safe fixes where possible, and a clear fix plan.

  • Fixed scope — $750
  • Screenshots + written findings
  • No retainer required

If your store does any of this, you're leaking sales

Small front-end bugs quietly cost orders. These are the ones I see most:

Cart drawer doesn't open correctly

Shoppers click "add to cart" and nothing visible happens, so they assume the store is broken.

Add-to-cart feedback is unclear

No drawer, no count change, no confirmation — buyers lose confidence in what they're buying.

Buy button buried on mobile

An oversized product image pushes the CTA below the fold, so fewer people ever reach it.

Layout breaks on small screens

Product pages overflow, variants get cramped, and spacing falls apart under ~430px.

Theme / app conflicts

An upsell, reviews, or sticky-cart app overrides theme JS and creates weird, intermittent behavior.

Slow, messy product pages

Layout shift and clutter make the page feel unreliable — and trust is what converts.

The offer

$750 Shopify Bug Fix

The fix includes issue diagnosis, screenshots, likely causes, priority ranking, and small safe fixes where possible. Larger fixes get a clear quote before any extra work.

What's included

  • Theme & cart drawer inspection
  • Mobile product page review
  • App / theme conflict check
  • Speed and UX red-flag pass
  • Screenshots of each issue
  • Likely cause for each finding
  • Priority ranking (what to fix first)
  • Small fixes are included when the cause is clear and safely patchable inside the fixed scope
  • Quote for larger implementation if needed

I work on duplicated themes or staging first whenever possible. I do not make risky live-theme edits without approval.

Sample work

Demo diagnostic: cart drawer + mobile product page repair

Demo diagnostic — not client work. This is a self-contained demo project. It shows how I document Shopify-style cart UX issues, mobile layout problems, and theme behavior fixes with before/after screenshots, changed files, and a short diagnostic report. This demo shows the type of documentation you get with the bug fix.

Quiet mobile bugs kill conversions. Customers tap, get weak or no feedback, assume nothing happened, and drop off. Nothing looks broken to the owner — the purchase flow is just leaking.

No clear response. The count stays at 0 and no drawer opens — so the shopper assumes it didn't work and leaves.

How it works

1

You send the details

Share your store/theme details and a few examples of the issue you're seeing.

2

I inspect

I check the cart, product page, mobile UX, and obvious theme/app conflicts.

3

You get a clear diagnosis

Screenshots, causes, fixes, and next actions — with small fixes applied where possible.

Who it's for

  • Shopify stores with broken cart or theme behavior
  • Small ecommerce stores without in-house devs
  • Agencies with overflow Shopify bugs
  • Founders who need a focused fix, not a giant retainer

Who it's not for

  • Anyone wanting a monthly maintenance retainer
  • Anyone expecting guaranteed conversion or revenue numbers
  • Stores that can't give theme access or a staging copy

FAQ

No. The proof on this page is a self-contained demo diagnostic, clearly labeled as such. It demonstrates how I find, fix, and document issues — not a real store's results.

Usually collaborator/theme access, or access to a duplicated theme. Enough to inspect the cart, product pages, and theme code.

I prefer to work on a duplicated theme or staging first, then publish once changes are verified. It keeps your live store safe.

You receive the findings and can request an implementation quote for any larger fixes. There's no obligation to continue.

Yes. $750 covers the fixed-scope Shopify bug fix. It includes diagnosis, screenshots, priority ranking, and small safe fixes where possible. Larger fixes are quoted separately before extra work starts.

No. I fix technical and UX problems like broken cart behavior, mobile layout issues, unclear feedback, and theme/app conflicts. I do not guarantee sales increases.

Get started

Send me your Shopify store URL and the issue you're seeing.

I'll review whether it fits the $750 bug fix. A couple of lines and a screenshot is enough to start.
