Shift4Shop → Shopify Migration + Omnisen

Project Overview
I’m looking for an experienced developer/team to handle a complete migration from Shift4Shop to Shopify, followed by a full setup of Omnisend and key growth apps.
This is NOT just a basic migration.
The goal is to build a clean, scalable, automation-driven ecommerce system with strong SEO preservation and future AI integration.


Scope of Work
Phase 1: Full Shopify Migration
Migrate all products (including variants, descriptions, images)
Migrate all customers (~11,000 contacts from CSV + platform export)
Migrate all products (~7,000 products from CSV + platform export)
Migrate order history
Rebuild collections, navigation, and site structure
Implement a clean, conversion-focused Shopify theme
Ensure mobile optimization and fast load speed


Phase 2: SEO Preservation (CRITICAL)
Create full 301 redirect map (old URLs → new Shopify URLs)
Preserve meta titles and descriptions
Maintain or improve current search rankings
Reconnect Google Search Console and sitemap
Ensure no broken links or indexing issues


Phase 3: Omnisend Setup (Native Integration)
Connect Omnisend to Shopify (no API workaround)
Import and clean customer data (segmentation-ready)
Ensure proper tracking:
product views
add-to-cart
checkout
purchases


Phase 4: Automation Setup (Required)
Set up and test:
Abandoned cart flow
Browse abandonment
Welcome email/SMS series
Post-purchase upsell
Win-back campaign


Phase 5: App & AI Stack Setup
Install and configure:
SEO optimization tool
Product reviews app
Upsell / cross-sell app
AI chatbot (basic setup)


Requirements (Must Have)
Proven experience with Shopify migrations (Shift4Shop/3dcart is a PLUS)
Strong understanding of SEO during migrations (301 redirects, indexing, etc.)
Experience with Omnisend or similar platforms (Klaviyo acceptable)
Ability to set up event tracking and automation flows correctly
Must provide examples of similar projects completed
Strong communication and ability to explain technical steps clearly


Timeline
Expected timeline: 3–5 weeks total
Do NOT apply if you cannot meet this realistically


Budget
Target budget: $1,500 – $3,500
Open to proposals based on experience and quality


What I’m Looking For
Someone who builds systems that don’t break
Attention to detail (especially with SEO + data)
Long-term mindset (future improvements, not just one-time job)


To Apply, Please Answer:

How do you ensure SEO is preserved during migration?
How will you verify abandoned cart and event tracking works correctly?
Share 2–3 relevant projects (links preferred)
What would you do first if hired?
