Is Your WooCommerce Store Costing You Sales? The 2026 Shopify Migration Checklist

Part 1: Calculating Your Revenue Leakage

Let’s do a simple audit. Open your store in Incognito mode.

1. The Speed Test (The 7% Rule)

Google states that for every second delay in mobile load time, conversions drop by 20%.

• WooCommerce Average: 4.5 seconds (Time to Interactive).
• Shopify Average: 1.5 seconds.
• The Math: If you do $1M/year, a 3-second delay is costing you potentially $200,000+ in lost impulse buys.

2. The Checkout Test (The Friction Rule)

Add a product to cart. Go to checkout.

• Do your customers have to manually type their address?
• Do they have to create an account?
• Shopify Pay: Remembers the credit card/address of 100 Million+ shoppers. They can checkout in one tap.
• The Math: Using Shop Pay increases checkout conversion by 1.72x.

3. The Downtime Test (The Reliability Rule)

How often does your site crash?

• “Oh, just for 10 minutes during the sale.”
• If you make $10,000/hour during a sale, 10 minutes = $1,600.
• Plus the LTV of the customers who are angry and never come back.

Part 2: The 2026 Migration Checklist

If you realized you are bleeding money, use this checklist to plan your move.

Phase 1: The Decision Gate

• [ ] Audit Traffic: Do I have >5,000 visitors/month? (If yes, migrate).
• [ ] Audit Complexity: Do I rely on custom PHP code that Shopify cannot replicate? (Likely no, nearly all logic can be replicated with Functions).
• [ ] Audit Budget: Do I have $15k-$30k to invest in a professional migration?

Phase 2: The Data Layer

• [ ] Product Schema: Do my products have “Options” (Size/Color) that map to Shopify Variants?
• [ ] Customer Segments: Do I have “Tags” on my customers (VIP, Wholesale) that I need to preserve?
• [ ] Order History: Do I need to migrate orders from 2019, or just 2024? (Migrating less data is cheaper/faster).

Phase 3: The SEO Preservation

• [ ] Crawl: Have I crawled my site to get a list of all 4,329 URLs?
• [ ] Map: Have I created the 301 Redirect Matrix?
• [ ] Content: Have I copied the Meta Titles and Alt Text to the new sheet?

Phase 4: The Design & UX

• [ ] Mobile First: Is the new theme designed for mobile thumb zones?
• [ ] Speed: Does the new theme score >90 on Google Lighthouse?
• [ ] Apps: Have I limited my App Stack to <10 essential apps?

Phase 5: The Post-Launch

• [ ] DNS: Do I have access to GoDaddy/Namecheap?
• [ ] Email: Have I warmed up my Klaviyo sending domain?
• [ ] Analytics: Is GA4 receiving the “Purchase” event correctly?

Part 3: The Cost of Doing Nothing

Let’s say a professional migration costs $25,000.

“That’s expensive,” you say.

But let’s look at your Cost of Inaction (COI).

• Hosting Fees (WPEngine/Kinsta): $500/mo ($6,000/yr)
• Developer Retainer (Updates): $1,000/mo ($12,000/yr)
• Lost Revenue (Speed): $50,000/yr (Conservative)
• Total COI: $68,000 / year.

The ROI: Spending $25,000 to save $68,000 is a 272% Return on Investment in Year 1.

There is no other investment in your business (Ads, Inventory, Staff) that yields that high of a return with that low of a risk.

Stop The Bleeding

Every day you stay on legacy infrastructure, you are paying a “Tech Tax.”
