What we deliver
Three Shopify integration outcomes every Redefine build delivers
0
synced per cycle
Shopify prices always match your ERP
ERP pricing pushes to Shopify on every change. Inventory levels sync on a schedule you define. Overselling becomes structurally impossible. See our ERP integration services for the full picture.
6+
channels unified
Orders from every channel flow into one queue
Amazon, eBay, wholesale portals, and your own checkout all feed back to Shopify as the order master. One fulfilment queue. No duplicate processing. No missed orders. Connects to your 3PL integration layer.
Real-time
Klaviyo events
Klaviyo fires on real Shopify events, server-side
Server-side event tracking captures checkout, purchase, and browse events reliably. No pixel dependency, no ad blocker gaps. Abandoned cart, post-purchase, and win-back flows trigger from real Shopify data, not approximations.
Client story
Eyeglasses123: Shopify, Amazon, and Klaviyo integrated. Manual operations automated. Revenue scaled to $6M.
01
Shopify and Amazon schema audit
All order channels mapped. Amazon marketplace data structures documented. Custom metafields and variant logic identified before any build started.
02
Order management integration live
Custom order management system connected Shopify with Amazon. Real-time order tracking and status sync eliminated manual order entry across both platforms.
03
Inventory sync across all channels live
Real-time inventory synchronization across Shopify, Amazon, and all marketplaces. Overselling eliminated. Return processing automated. Supplier oversight improved.
$6M annual revenue
$0M
Operational costs reduced through automation and improved supplier oversight. Inventory accuracy improved across all channels. Revenue scaled to $6M.
The problem
Eyeglasses123 faced operational complexity from rapid growth across multiple marketplaces. Managing returns, synchronizing inventory in real time, and reducing overhead all required manual intervention at every step. Each new channel added more manual work, not just more revenue.
What we built
Custom dropshipping operations connected to Shopify. A real-time order management system provided order tracking and synchronization across all channels. Inventory positions updated automatically. Return processing automated end-to-end without manual touchpoints.
The result
Annual revenue scaled to $6 million. Operational costs reduced through automation and improved supplier oversight. Inventory accuracy improved across all channels and marketplaces. The integration layer allowed adding new channels without proportionally growing headcount.

Why custom integration wins
Three myths Shopify merchants believe about integration
Every column on the left is something a Shopify merchant told us before they tried it. The right is what we build instead.
Myth 01
A Shopify app will handle our ERP integration
App store connectors work for standard Shopify stores with simple data. They break on custom metafields, tiered B2B pricing, bulk product updates, and Shopify API version transitions. Most custom Shopify integration company engagements we win come from teams that tried an app first.
What we build instead
A custom connector that knows your exact Shopify data model
We map your metafields, price tier logic, and variant structure before writing a line of code. The connector handles your data exactly as it exists in your Shopify store, not a generic approximation. No workarounds. No edge-case failures.
See our NetSuite Shopify integration →Myth 02
Integration is a one-time project, set it and forget it
Shopify releases new API versions on a regular cycle and deprecates old ones. Without drift detection, your connector breaks silently when Shopify removes an endpoint you depend on. Most teams discover this during a Shopify update, not before.
What we build instead
Schema drift detection and 30-day hypercare on every build
Every Shopify integration we build monitors the API surface it depends on. If Shopify deprecates an endpoint or changes a response format, our monitoring alerts before data breaks. The 30-day hypercare period includes direct Slack access to your build engineer through the first Shopify update cycle.
Myth 03
We need more scale before custom Shopify integration is worth it
Manual sync costs are fixed per order, so they grow linearly with your store. The cost-of-inaction calculator above shows this precisely: at 80 orders per day, you are spending over $100K per year on manual sync labor. Integration pays back in weeks, not years.
What we build instead
Fixed-price builds that pay back in 30 to 60 days for most Shopify stores
The cost-of-inaction counter above runs on your actual order volume. Most Shopify stores at 50 or more orders per day have a payback period under 60 days. The integration cost is fixed. The savings compound with every order you add. Earlier is always better.
Common questions
Shopify integration consulting: what you need to know
We build integrations for Shopify Basic through Shopify Plus and headless Shopify builds using Hydrogen. Shopify Plus unlocks additional API rate limits and the B2B pricing API that we use in more complex integration scenarios. See our ecommerce integration services page for broader platform coverage.
A single Shopify connector typically goes live in 12 to 18 days from signed brief. Multi-system builds connecting Shopify to ERP, 3PL, and analytics simultaneously run 6 to 10 weeks. The go-live date is confirmed in the proposal before any work starts. Shopify schema audits on day one prevent scope creep from undiscovered custom metafields or product logic.
App store connectors fail on custom metafields, tiered B2B pricing, high order volumes, and complex transformation logic. Custom Shopify integration handles your specific data model. It also includes drift detection for Shopify API version changes, since app connectors often break silently when Shopify deprecates the endpoint they use.
Single Shopify connector endpoints start from $3,200 fixed-price. Full stack builds connecting Shopify to ERP, 3PL, customer relationship management, and analytics start from $14,000. Architecture audits are $800 and credited toward any build. There are no ongoing subscription fees for the integration itself. Optional maintenance retainers start from $400 per month.
Shopify deprecates API versions regularly. Every integration we build includes schema drift detection and automated alerting. If a Shopify API change affects your integration, our monitoring fires before data breaks silently. The 30-day hypercare period and optional managed retainers keep your Shopify integration solutions stable through every API transition.
Is this the right engagement
Is this the right Shopify integration engagement?
Not sure? Tell us your Shopify setup and what needs to connect. We will be honest about whether it fits.
Good fit
- You run Shopify or Shopify Plus and need it connected to ERP, customer relationship management, 3PL, or multi-channel marketplaces.
- Your team manually exports data from Shopify into other systems at least once per day.
- You tried an app store connector or iPaaS for Shopify and hit a wall with custom data or edge cases.
- You want a fixed scope, a fixed price, and a go-live date you can plan around.
Not the right fit
- Your existing Shopify app integrations work reliably for your current order volume and data model.
- You need someone to build or redesign your Shopify store itself, theme, user experience, product pages.
- You are still evaluating whether to migrate off Shopify to a different platform entirely.
- You want an open-ended development retainer with no defined deliverables or go-live commitment.
