💻 Shopify Developer SOP
Theme Customization, Speed Optimization & Conversion-Ready Builds
Why Your Code Quality Matters
The Store That Lost $50,000/Day
A client came to us after their "cheap" developer delivered a store. It looked okay on the surface. But hidden underneath:
- PageSpeed: 23 (should be 85+)
- 4+ seconds load time on mobile
- Checkout had JavaScript errors
- 10% of add-to-cart clicks didn't work
Result? For every 100 visitors, only 1 completed a purchase. Industry average is 2-3. They were losing $50,000+ per day in potential sales because of bad code.
We rebuilt the store. PageSpeed hit 92. Conversion rate tripled.
🚨 NON-NEGOTIABLE CODE STANDARDS
1. NEVER WORK ON LIVE THEME
Always duplicate theme or work on development store. One mistake = client's live store broken.
2. MOBILE-FIRST ALWAYS
70% of ecommerce traffic is mobile. Build for 375px width FIRST, then scale up to desktop.
3. SPEED IS NOT OPTIONAL
Mobile PageSpeed target: 85+. Every decision — image size, app choice, custom code — must consider speed.
4. TEST EVERYTHING
Before marking any task complete: Test on mobile, test on desktop, test checkout flow, check console errors.
⚠️ CRITICAL: Shopify Store Build Rules
🚨 CURRENCY CHECK - FIRST STEP
NEVER keep currency as INR for US/international clients!
- Verify currency setting IMMEDIATELY after store creation
- Change to USD (or client's target currency)
- Double-check currency on checkout page during QA
📋 Mandatory Store Elements Checklist
- Minimum 3 trending products per practice store
- ALL policy pages must have content: Privacy, Shipping, Refund, Terms
- Live chat integration mandatory (Shopify Inbox or equivalent)
- Track Order page - must be functional
- About Us page - with real content, not placeholder
- Contact page - with functional form
- SEO completed for ALL pages and products
📱 Required App Integrations
| Google app | Install and configure |
| TikTok app | Install and configure |
| Facebook app | Install and configure |
| Order tracking app | Functional and tested |
⏱️ Time Standards
Practice store: Maximum 2 hours per store
Client store speed: 1 complete store + homepage of 2nd store = 1 day
Remember: Shopify is 2x easier than WordPress - speed should reflect this!
🔍 SELF QA PROTOCOL - MANDATORY
Review EVERY element 3-5 times before submission — this is MANDATORY, not optional
Pre-Submission Checklist:
- ✅ Desktop view check: All pages, all links, all buttons
- ✅ Mobile responsiveness: Every section, every page
- ✅ Click EVERY link on the site - document any broken links
- ✅ Test complete flow: Add to Cart → Checkout
- ✅ Verify ALL images display correctly (no broken images)
- ✅ Spelling/grammar check on ALL text content
- ✅ Page speed test - must meet 85+ benchmark
⚠️ NEVER ask client to check store until 100% complete and self-verified
⚠️ If clients point out preventable mistakes — you are personally responsible
Quality Standards & Ownership
🎯 Creative Ownership Principle
Each team member is 100% responsible for their assigned work quality.
- Responsibility includes: Colors, designs, logos, product formatting, overall aesthetic
- Standard is to OVERDELIVER - not just meet expectations
- This is what separates Digital Heroes from average agencies
⚠️ Zero Tolerance Policy
After 15 days of onboarding: ONE careless mistake = Potential removal
- No space for making preventable mistakes in live projects
- Mistakes that client points out = Personal responsibility
- Check 10 times before giving to client - each line, each design element
👥 Peer Review Process
- Get projects checked by each other before sending to client
- Fresh eyes catch issues original developer might miss
- Peer review is teamwork - not criticism
Quality & Delivery Best Practices
1️⃣ The Fresh Eyes Rule 👀
After finishing work, wait 2 hours before reviewing.
Your eyes see what they expect. Fresh eyes see what's there.
2️⃣ The Client Perspective Check 🤔
Before submitting, ask yourself:
"Would I be happy if I paid for this?"
3️⃣ The 5-Minute Audit ⏱️
After every delivery, spend 5 minutes finding issues you might have missed:
- Check on mobile
- Check in incognito mode
- Check in different browser
4️⃣ Show, Don't Tell 📸
Never say "it's done." Show proof:
- Screenshot
- Loom recording
- Live preview link
5️⃣ The Walkthrough Video 🎥
For every major delivery, record a 2-minute Loom explaining what was built.
Reduces back-and-forth by 80%
6️⃣ Version Control 📁
Never overwrite. Always save versions: v1, v2, v3, etc.
Especially for theme files — keep a backup!
7️⃣ The "Works for Me" Fallacy ⚠️
"It works on my machine" is NOT acceptable.
If it doesn't work for the client, it's broken. Period.
8️⃣ The Testing Trifecta ✅
Test every feature 3 ways:
- Happy path — as intended
- Error path — with wrong inputs
- Edge cases — extreme scenarios
9️⃣ The Rollback Plan 🔙
Before any major change, know how to undo it in 5 minutes.
Always have an escape route.

Getting Store Access (First Step for ANY Project)
⚠️ NEVER Start Work Without Proper Access
Before you touch ANY code or settings, you MUST have proper collaborator access to the client's Shopify store. Working without official access = security risk and potential account issues.
📋 Step-by-Step: Getting Collaborator Access
Send this message to the client (via PM or directly):
"To get started, I'll need access to your Shopify store. Here's how:
1. Log into your Shopify admin
2. Go to Settings → Users and permissions
3. Scroll to 'Collaborators' section
4. You'll see a 4-digit collaborator request code
5. Please share that code with me
This is the secure way to grant access without sharing passwords."
STEP 2: Request Access Using the Code
1. Go to accounts.shopify.com/store-login
2. Enter the client's store URL (mystore.myshopify.com)
3. Click "Log in with collaborator request"
4. Enter the 4-digit code the client provided
5. Fill in your collaborator request details
6. Select permissions needed (usually "Full access")
7. Submit the request
STEP 3: Client Approves Your Request
Send this to client:
"I've submitted my access request. Please check your Shopify admin:
Settings → Users and permissions → Collaborators
You should see my request - please click 'Approve'."
STEP 4: Verify Your Access
Once approved:
- Log into the store
- Check you can access: Theme editor, Settings, Products, Apps
- If anything is restricted, ask client for additional permissions
🔐 Access Permission Levels
| Project Type | Permissions Needed | Why |
|---|---|---|
| Full Store Build | Full access (all permissions) | Need to configure everything |
| Theme Customization | Themes, Online Store | Only need design access |
| Product Upload | Products, Collections | Manage catalog only |
| App Integration | Apps, Settings | Install and configure apps |
| Speed Optimization | Themes, Apps, Settings | Need to modify code and apps |
❌ Common Access Problems & Solutions
- "I can't find the collaborator code" → The client needs to be on Shopify's paid plan. Trial stores don't have this feature.
- "Client wants to share login instead" → Politely decline. Explain collaborator access is more secure and trackable.
- "Access request not showing for client" → Make sure you used the correct store URL (.myshopify.com, not custom domain).
- "Some areas are restricted" → Ask client to edit your collaborator permissions in Settings → Users.
- "Client is on Shopify Lite" → Lite plans have limited access. May need to work differently or upgrade.
✅ Before Starting ANY Work, Confirm:
- You have collaborator access (not shared login)
- You can access the theme editor
- You can see the Apps section
- You have access to Settings
- You've DUPLICATED the current theme as backup
Theme Selection & Initial Setup
Recommended Themes
| Theme | Price | Best For | Speed Score |
|---|---|---|---|
| Dawn | Free | Minimalist brands, fast loading | 90+ |
| Prestige | $350 | Luxury, high-end products | 85-90 |
| Impulse | $350 | Versatile, many sections | 80-85 |
| Symmetry | $340 | Fashion, grid layouts | 85-90 |
Theme Setup Checklist
- Go to Online Store → Themes
- Add theme (from library or upload)
- IMPORTANT: Click "Duplicate" before customizing
/* STEP 2: Theme Settings (Before Sections) */
- Colors: Set primary, secondary, background, text
- Typography: Heading font + Body font (max 2 families)
- Buttons: Style, radius, hover states
- Layout: Container width, spacing
/* STEP 3: Logo & Favicon */
- Logo: PNG with transparency, 200-400px wide
- Favicon: 32x32 or 64x64 PNG
- Check header on mobile — logo should be visible
The Developer Who Worked on Live Theme
A junior developer was making "quick changes" directly on a client's live theme. No backup. They accidentally deleted the header section file.
Result: Client's store showed no navigation for 45 minutes during peak traffic hours. Panic calls. Lost sales. Angry client.
Homepage Section Structure
🏆 The Perfect Homepage Flow
Every section should have a PURPOSE. No section exists just to look pretty — it either builds trust, showcases products, or drives action.
Essential Homepage Sections (In Order)
| # | Section | Purpose | Key Elements |
|---|---|---|---|
| 1 | Announcement Bar | Highlight key offer | "Free shipping over $50" | Sale message | Trust statement |
| 2 | Header | Navigation & branding | Logo + Menu: Home, Catalog, Collections, About Us, Contact Us, FAQ, Track Your Order + search, cart icon |
| 3 | Hero Banner | First impression | Headline (7 words max), subtext, CTA button, lifestyle image |
| 4 | Trust Bar | Build confidence | Free shipping | Easy returns | Secure payment | Money-back guarantee |
| 5 | Featured Products | Show best sellers | 4-8 products, "Best Sellers" or "New Arrivals" |
| 6 | Value Props | Why buy from us | 3-4 icons with benefits (Quality, Fast Shipping, etc.) |
| 7 | Collection Grid | Category navigation | Shop by category with images |
| 8 | Testimonials | Social proof | 3-6 reviews with photos if possible |
| 9 | About/Story | Brand connection | Short brand story, founder image optional |
| 10 | FAQ | Answer objections | 5-8 common questions |
| 11 | Newsletter | Capture emails | Email input, incentive (10% off) |
| 12 | Footer | Links & trust | Navigation, policies, contact, social, payment icons |
Hero Section Code Example
<section class="hero">
<div class="hero-content">
<h1>Premium Skincare for Glowing Skin</h1>
<!-- Headline: 7 words max, benefit-focused -->
<p>Dermatologist-formulated. Cruelty-free. Results in 14 days.</p>
<!-- Subtext: Address objections, promise result -->
<a href="/collections/all" class="btn-primary">
Shop Now
</a>
<!-- CTA: Action-oriented, high contrast -->
</div>
</section>

Essential Shopify Apps
⚠️ App Rule: Less is More
Every app you install slows down the store. Only install what's TRULY needed. 5-8 apps is healthy. 15+ apps = performance issues.
📊 Recommended Apps by Category
| Category | Best App | Free Alternative | Purpose |
|---|---|---|---|
| Reviews | Judge.me ($15/mo) or Loox ($9.99/mo) | Judge.me Free | Product reviews with photos |
| Email Marketing | Klaviyo | Shopify Email | Abandoned cart, campaigns |
| Upsell/Cross-sell | ReConvert, Bold Upsell | Shopify's built-in | Increase AOV |
| Pop-ups | Privy, OptiMonk | Shopify Forms | Email capture, offers |
| SEO | SEO Manager, Plug in SEO | Manual optimization | Meta tags, sitemaps |
| Social Proof | Fomo, Sales Pop | Theme built-in | "X just bought" notifications |
| Shipping | ShipStation, Shippo | Shopify Shipping | Label printing, tracking |
| Returns | Loop Returns, AfterShip | Manual process | Self-service returns portal |
| Subscriptions | Recharge, Bold Subscriptions | None (complex feature) | Recurring orders |
| Chat/Support | Gorgias, Tidio | Shopify Inbox | Live chat, customer support |
🚫 Apps to AVOID (Speed Killers)
- Multiple review apps → Pick ONE. Don't stack them.
- Heavy page builders → Use theme editor instead when possible.
- Too many pop-up apps → One pop-up app maximum.
- Abandoned cart apps when Klaviyo exists → Duplicate functionality.
- Apps that inject lots of JavaScript → Check PageSpeed after install.
- Free apps with no reviews → Often inject unwanted code or malware.
📋 App Installation Checklist
Before installing ANY app:
- Check current PageSpeed score (note it down)
- Read reviews — look for complaints about speed
- Install app
- Check PageSpeed again — did it drop significantly?
- If score dropped more than 10 points → reconsider the app
- Test functionality thoroughly
- Document which apps are installed (for future reference)
🔧 App Removal: Clean Uninstall
1. Go to Apps → App you want to remove
2. Click "Delete" or "Uninstall"
3. CRITICAL: Check theme code for leftover snippets
4. Online Store → Themes → Actions → Edit code
5. Search for the app name in all files
6. Remove any leftover {% include 'app-name' %} tags
7. Check Layout/theme.liquid for injected scripts
8. Test site after cleanup
Many apps leave code behind that continues to slow your store!

Creating Custom Blocks & Sections
🔥 SUPERPOWER: Use Claude or ChatGPT to Create ANY Custom Section
You don't need to memorize Liquid syntax. AI can write it for you. Here's the exact process:
Step-by-Step Custom Section Creation
"I need to create a custom Shopify section for [DESCRIBE WHAT YOU NEED].
The section should be editable from the theme customizer.
Include a schema with these editable fields: [LIST FIELDS].
Use Shopify 2.0 JSON templates.
Make it responsive for mobile."
/* EXAMPLE PROMPT */
"Create a Shopify section for a 3-column features grid.
Each column should have: icon (image), heading (text), description (richtext).
Max 3 blocks. Section should have a main heading.
Include schema for customizer editing."
/* STEP 2: AI generates code like this */
Where to Paste the Code
| Step | Action | Path |
|---|---|---|
| 1 | Go to theme editor | Online Store → Themes → [Theme] → Edit Code |
| 2 | Navigate to Sections folder | Sections/ |
| 3 | Create new file | Click "Add a new section" → name it (e.g., custom-features.liquid) |
| 4 | Paste AI code | Copy from AI, paste into new file, Save |
| 5 | Add to page | Customize theme → Add section → Your new section appears! |
⚠️ Always Test New Sections
- Never add custom code to live theme directly
- Test on duplicate theme first
- Check mobile responsiveness
- Verify no console errors

🛠️ Technology Decision Guide
📊 Which Platform for This Project?
| If Client Needs... | Recommend | Why |
|---|---|---|
| Simple e-commerce (1-100 products) | Shopify | Easy management, built-in payments |
| Blog + basic site | WordPress | SEO-friendly, tons of plugins |
| Visual landing pages | Webflow | Designer-friendly, no code |
| Custom web app / SaaS | React/Next.js | Full control, scalability |
| E-commerce 1000+ products | Shopify Plus / WooCommerce | Advanced features, bulk operations |
| Portfolio / simple brochure | HTML/CSS or Webflow | Fastest load, minimal complexity |
⚠️ Platform Red Flags
- Client wants Shopify for a booking site → Recommend better tools (Calendly, Square)
- Client wants WordPress for complex e-commerce → WooCommerce has limits, discuss
- Client wants custom code for simple landing page → Overkill, suggest Webflow
- Client insists on Wix/Squarespace → We don't work with those, politely decline
Speed Issues
| Problem | Cause | Fix |
|---|---|---|
| PageSpeed below 50 | Large images, too many apps, slow theme | 1) Compress images (TinyPNG) 2) Remove unused apps 3) Check theme bloat |
| LCP (Largest Contentful Paint) high | Hero image too large or not lazy loaded | 1) Compress hero to <200KB 2) Add loading="lazy" to images 3) Use WebP format |
| CLS (Cumulative Layout Shift) | Images without dimensions, dynamic content | 1) Add width/height to all images 2) Reserve space for dynamic elements |
| Render-blocking resources | Too many CSS/JS files loading | 1) Defer non-critical JS 2) Inline critical CSS 3) Remove unused scripts |
Console Errors
| Error Message | Common Cause | Solution |
|---|---|---|
Uncaught TypeError: Cannot read property 'xxx' of undefined |
Script running before element exists | Wrap in DOMContentLoaded or move script to bottom of page |
Failed to load resource: 404 |
Missing file (image, JS, CSS) | Check file path, upload missing file, or remove reference |
Mixed Content Error |
HTTP content on HTTPS page | Change all URLs to https:// or use protocol-relative // |
CORS error |
External resource blocking cross-origin | Use Shopify-hosted assets or proxy through your server |
Common Shopify Issues
⚠️ Issue: Section Not Showing in Customizer
Cause: Schema syntax error or missing presets
Fix:
- Check schema JSON for syntax errors (missing commas, quotes)
- Ensure "presets" array exists with a name
- Clear browser cache and refresh customizer
⚠️ Issue: Checkout Page Not Styled
Cause: Checkout customization is limited on Shopify Basic/Standard
Fix:
- Use Settings → Checkout to set logo, colors
- Full checkout.liquid editing requires Shopify Plus
- Recommend apps like Checkout X for more customization
⚠️ Issue: Products Not Showing in Collection
Cause: Product not added to collection or not published
Fix:
- Check Products → [Product] → Organization → Collections
- Verify product status is Active, not Draft
- Check collection's smart/manual conditions
Theme-Specific Debugging
{{ product | json }}
/* Shows all product data as JSON */
{{ collection.products | size }}
/* Shows number of products in collection */
{% if request.design_mode %}
/* Only shows in theme editor */
DEBUG: This section is loading
{% endif %}
/* Check if object exists before using */
{% if product.featured_image %}
{{ product.featured_image | image_url: width: 500 | image_tag }}
{% else %}
No image available
{% endif %}

Debugging Decision Tree
💡 Systematic Debugging Saves Hours
Before asking for help, follow this flowchart. 80% of issues are solved in the first 3 steps.
Step-by-Step Debugging Process
| Step | Check | Common Fix |
|---|---|---|
| 1. Console Check | Open browser DevTools → Console tab | Red errors point to the exact line number |
| 2. Preview Mode | Are you looking at live site or preview? | Changes only show in preview until published |
| 3. Cache Clear | Hard refresh: Ctrl+Shift+R | Solves 40% of "why isn't it updating" issues |
| 4. Syntax Check | Missing {% endif %}, {{ }}, quotes? | Use syntax checker or format the code |
| 5. Object Exists? | Is the object you're accessing defined? | Wrap in {% if object %} check |
| 6. Isolate Issue | Comment out sections until error goes | Find which block causes the problem |
| 7. App Conflict | Disable apps one by one | Apps often inject conflicting JS/CSS |
Common Error Messages & Fixes
| Error Message | What It Means | Fix |
|---|---|---|
Liquid error: undefined method |
Object doesn't have that property | Check spelling, use {{ item | inspect }} to see properties |
Cannot read property of null |
JavaScript accessing undefined variable | Add null check: if (variable) { ... } |
expected block close |
Missing {% endif %} or {% endfor %} | Count opening vs closing tags |
Argument error: invalid |
Wrong filter parameter | Check Shopify filter documentation |
| Page is completely blank | Fatal Liquid syntax error | Revert last change, add code bit by bit |

Day-to-Day Quick Reference
🔧 Quick Fixes for Common Issues
These are problems you'll face almost every day. Know them by heart.
🖼️ Image Issues
| Problem | Cause | Quick Fix |
|---|---|---|
| Image looks blurry | Low resolution or wrong aspect ratio | Request 2x size from client (2000px for 1000px display). Use WebP format. |
| Image not loading | File too large or wrong format | Compress with TinyPNG. Convert to WebP/JPG. Max 500KB per image. |
| Image stretching | Wrong aspect ratio in theme | Check theme settings for aspect ratio. Use object-fit: cover in CSS. |
| Product images different sizes | Client uploaded inconsistent images | Resize all to same ratio (1:1 or 3:4). Use Shopify's image resize URL params. |
| Hero image not full width | Container has max-width | Use full-width section or remove container constraints. |
📝 Text & Content Issues
| Problem | Cause | Quick Fix |
|---|---|---|
| Font not showing | Font not loaded or wrong name | Check theme settings → Typography. Verify Google Font name is exact. |
| Text overlapping on mobile | Fixed width or absolute positioning | Use responsive units (%, vw, rem). Test at 375px width. |
| Description shows HTML tags | Using wrong Liquid filter | Use {{ product.description }} not {{ product.description | escape }} |
| Currency showing wrong | Store settings or wrong filter | Settings → General → Currency. Use {{ price | money }} filter. |
| Product title cut off | Container too small | Increase container width or use text-overflow: ellipsis with title attribute. |
🛒 Cart & Checkout Issues
| Problem | Cause | Quick Fix |
|---|---|---|
| Add to Cart not working | JavaScript error or form issue | Check console for errors. Verify product is available (not draft/out of stock). |
| Cart drawer not opening | Theme JS broken or conflict | Check for app conflicts. Try disabling apps one by one. |
| Checkout button missing | Checkout disabled or payment not set | Settings → Payments. Ensure at least one payment method active. |
| Discount code not applying | Code expired or restrictions | Check Discounts → verify dates, minimum order, customer eligibility. |
| Shipping not calculating | Shipping zones not set | Settings → Shipping → Add rates for customer's country. |
⚡ Performance Issues
| Problem | Cause | Quick Fix |
|---|---|---|
| Site loading slowly | Large images, too many apps | Compress images, remove unused apps, defer non-critical JS. |
| PageSpeed under 50 | Multiple issues | 1. Compress images 2. Remove unused apps 3. Use lazy loading 4. Minimize custom JS |
| CLS issues (layout shift) | Images without dimensions | Add width/height to img tags. Reserve space with aspect-ratio CSS. |
| LCP issues (slow paint) | Hero image too large | Preload hero image. Use srcset for responsive images. |
| Third-party scripts slow | Apps loading synchronously | Defer non-critical app scripts. Consider ditching slow apps. |
📱 Mobile-Specific Issues
| Problem | Cause | Quick Fix |
|---|---|---|
| Page zoomed in on mobile | Missing viewport meta | Add: <meta name="viewport" content="width=device-width, initial-scale=1"> |
| Horizontal scroll on mobile | Element wider than screen | Find element with fixed width. Use max-width: 100% and overflow-x: hidden. |
| Buttons too small to tap | Touch target under 44px | Minimum button size: 44px × 44px. Add padding if needed. |
| Menu not opening on mobile | Hamburger menu JS broken | Check for JS errors. Verify data-attributes are correct. |
| Sticky header covering content | No scroll padding | Add scroll-padding-top equal to header height. |
🔌 App Conflicts & Issues
| Problem | Cause | Quick Fix |
|---|---|---|
| App widget not showing | App block not added or disabled | Theme editor → Add app block. Or manually add app embed code. |
| Two apps conflicting | Both modifying same element | Disable one, test. Contact app support. May need to choose one. |
| App slowing down site | Heavy JavaScript or many requests | Check in PageSpeed which scripts are slow. Remove or replace app. |
| App leaving code after uninstall | App didn't clean up properly | Search theme files for app name. Remove leftover snippets and includes. |
| Reviews not importing | API limits or format issues | Check import format (CSV). Import in smaller batches. Contact app support. |
🎨 Theme Editor Issues
| Problem | Cause | Quick Fix |
|---|---|---|
| Theme editor not loading | Browser cache or extension conflict | Clear cache, try incognito mode, disable ad blockers. |
| Changes not saving | Session timeout or permissions | Refresh page, log out and back in. Check you have edit permissions. |
| Section disappeared | Accidentally removed or template changed | Check template selection. Use Undo or revert to previous version. |
| Custom CSS not applying | Specificity or cache | Add !important (temporarily). Check if CSS file is loaded. Clear cache. |
| Preview link shows password page | Store is password protected | Use preview link with password bypass, or temporarily disable password. |
📦 Product & Collection Issues
| Problem | Cause | Quick Fix |
|---|---|---|
| Product not showing in collection | Wrong tags or manual collection | Check collection conditions. Add correct tag or manually add product. |
| Variants not showing | Variant options not set up | Products → Edit → Add variant options (Size, Color, etc.). |
| "Sold Out" showing incorrectly | Inventory not tracked or zero | Check product inventory settings. Update stock quantity. |

Handling Difficult Situations
🔴 Client's Theme is Heavily Customized/Broken
🎯 Task Priority Order (What Comes First)
Handle in this order every day:
- 🔴 P0 - Production Bugs/Site Down → Live site issues are IMMEDIATE. Drop everything.
- 🔴 P0 - Security Issues → Any vulnerability or breach. Fix first, explain later.
- 🔴 P0 - Deadline-Day Tasks → Work due TODAY must be completed and handed off.
- 🟡 P1 - PM/Client Questions → Respond within 1 hour. Don't leave them waiting.
- 🟡 P1 - Active Project Work → Tasks with upcoming deadlines (next 2-3 days).
- 🟢 P2 - Code Reviews → Don't block teammates waiting for your review.
- 🟢 P2 - Testing & QA → Test your own work before handoff.
- ⚪ P3 - Learning & Optimization → Non-urgent improvements, skill building.
Golden Rule: Live site issues > Deadlines > Communication > Deep work.
🔴 Client's Theme is Heavily Customized/Broken
Situation: Previous developer left messy code, theme is unstable.
Response: Document issues found, inform PM of risks. Recommend cleanup before new features. If client won't approve cleanup time, document that you advised against proceeding.
Rule: Never promise results on broken foundations. CYA with documentation.
🔴 Feature Request is Technically Impossible
Situation: Client wants something Shopify can't do (e.g., real-time inventory across platforms).
Response: "This isn't natively supported by Shopify. We have two options: [Alternative A] or [Third-party app]. Here are the pros/cons of each."
Rule: Always provide alternatives. Never just say "can't be done."
🔴 Client Provides Wrong/Incomplete Assets
Situation: Images are low-res, logos are JPG not SVG, files are missing.
Response: Create a specific asset checklist: "Please provide: Logo in SVG format, product images min 2000x2000px, brand colors in HEX codes."
Rule: Never proceed with bad assets. Timeline pauses until correct assets received.
🔴 Changes Broke Something in Production
Situation: After deploying, something stopped working on the live site.
Response: Immediately revert to backup/previous version. Document what happened. Fix in dev environment first, then redeploy carefully.
Rule: Always have rollback plan. Never debug on live site during business hours.
🔴 Client Wants Unlimited Revisions
Situation: Client keeps requesting "one more small change" endlessly.
Response: Route to PM: "This is outside our agreed scope. PM will discuss options for extending the project."
Rule: Developers don't negotiate scope. Push to PM for scope discussions.
🔴 Third-Party App Causing Conflicts
Situation: Client's installed app is breaking your custom code.
Response: Document the conflict with screenshots. Recommend removing the conflicting app or finding an alternative. Don't hack around bad apps.
Rule: We don't support fixing other developers' or apps' broken code.
🔴 Client Editing Theme and Breaking Things
Situation: Client made changes in theme editor that broke your work.
Response: "I see changes were made to the theme since our last delivery. Fixing these would be additional work. I recommend we restore to the last working version and re-apply your changes properly."
Rule: Changes made by client = new scope. Not our responsibility to fix for free.
🔴 Site Speed Still Slow After Optimization
Situation: Client unhappy with speed even after your optimization.
Response: "We've optimized all code within our scope. The remaining issues are from [apps/images/third-party scripts]. Here's what else can be done and the associated costs."
Rule: Set expectations early. Some slowness is out of our control (apps, hosting, images).

📖 Success Story: The 3-Second Fix Worth $50,000
A client's store was loading in 8 seconds on mobile. Their bounce rate was 70%. They were
ready
to give up on their business.
Our developer spent 4 hours optimizing: lazy loading images, deferring scripts, optimizing
the
theme. The result? Load time dropped to 2.1
seconds.
The impact? Bounce rate dropped to 35%. Conversion
rate
doubled. The client made an extra $50,000 that
quarter
— from a single optimization project.
The lesson: Technical excellence isn't abstract — it's someone's rent payment, their
kid's
college fund, their retirement. Your work matters.
