How to Fix Common Shopify Store Issues (And When to Get Expert Help)
Running a Shopify store is one of the fastest ways to launch an ecommerce business — but as your store grows, so do the problems.
From slow loading speeds to broken apps and checkout errors, these issues can directly impact your sales and customer experience.
In this guide, we'll walk through the most common Shopify problems, how to fix them, and when it makes sense to get professional support.
1. Slow Shopify Store Speed
Why it matters
A slow store can kill conversions. Even a one-second delay can reduce sales significantly.
Common causes
- Too many apps installed
- Unoptimised images
- Heavy or poorly coded themes
- Third-party scripts loading on every page
Quick fixes
- Compress and resize images before uploading
- Remove unused apps entirely — not just disabled
- Switch to a lightweight, well-coded theme
- Minimise external scripts and tracking pixels
When to get help
If your store is still slow after basic fixes, it likely requires deeper technical optimisation — caching strategies, lazy loading, or theme-level code changes.

2. Shopify Apps Causing Conflicts
Why it happens
Apps often inject code directly into your store's theme. When multiple apps interact with the same elements, things can break in unpredictable ways.
Common issues
- Features not working correctly after a new app install
- Design or layout breaking on certain pages
- Checkout disruptions affecting conversion rates
Quick fixes
- Disable recently installed apps and test after each one
- Check app compatibility notes in the Shopify App Store
- Remove unused apps completely rather than just disabling them
When to get help
App conflicts can be difficult to diagnose without technical knowledge of Liquid, JavaScript, and theme architecture.
Our Shopify support New Zealand service handles app setup and conflict resolution for NZ businesses. UK businesses can rely on our Shopify maintenance service UK for ongoing fixes and app management.
3. Broken Layouts or Design Issues
Common problems
- Mobile layout not responsive or elements overlapping
- Sections displaying incorrectly after a theme update
- Fonts and styles inconsistent across pages
Quick fixes
- Check theme settings in the Shopify theme editor first
- Test across multiple devices and browsers
- Revert recent changes using Shopify's theme version history
When to get help
If the issue involves code — Liquid templates, CSS, or JavaScript — it's best handled by a Shopify expert to avoid introducing new problems.
Our Shopify support New Zealand plans include ongoing design and UX improvements. UK brands can use our Shopify maintenance service UK for continuous updates and front-end fixes.
4. Shopify Store Not Converting
Why this happens
Even with strong traffic, poor user experience or missing trust signals can stop customers from completing a purchase.
Common causes
- Slow loading pages on mobile
- Confusing or cluttered navigation
- Weak product pages with thin descriptions
- Lack of reviews, trust badges, or social proof
Quick fixes
- Improve product descriptions with clear benefits and specifications
- Add customer reviews and trust badges at the checkout
- Simplify navigation and reduce the number of menu items
- Optimise the mobile experience end to end
When to get help
Conversion rate optimisation is an ongoing process that requires regular testing, analysis, and iterative improvements rather than a one-time fix.
Our Shopify support New Zealand plans include CRO-focused updates. Our Shopify maintenance service UK helps improve performance and conversions over time with a predictable monthly cost.
5. Checkout or Payment Issues
Common problems
- Payments failing at the point of purchase
- Checkout errors preventing order completion
- Shipping rates not calculating correctly
Quick fixes
- Check your payment provider setup and test in a staging environment
- Review shipping zones and rates in Shopify settings
- Test the full checkout flow regularly, including on mobile
When to get help
Checkout issues directly impact revenue and should be resolved as quickly as possible — not queued behind other work.

When Should You Hire a Shopify Expert?
You should consider ongoing support if:
- You're spending too much time fixing issues instead of running your business
- Your store is growing and needs regular updates and improvements
- You don't have in-house technical expertise for Shopify development
- You want to proactively improve performance and conversions rather than react to problems
Instead of hiring a full-time developer or engaging an expensive agency for one-off projects, many businesses are turning to Shopify monthly support services — a cost-effective way to access expert help on an ongoing basis.
A Better Way to Manage Your Shopify Store
With a monthly support plan, you get:
- Ongoing fixes and improvements without the overhead of a full-time hire
- Faster turnaround times with a dedicated team who knows your store
- Predictable monthly costs instead of unpredictable agency invoices
- Expert help available when you need it, not just when a project is scoped
