For e-commerce brands running on Shopify, Salesforce Commerce Cloud, Magento, BigCommerce, or bespoke websites, integrating a new vendor—whether an ERP, WMS, OMS, payment provider, or marketing platform—is an essential step in scaling operations.
But too often, brands rush into integrations without fully understanding their current system landscape or identifying key business use cases. This leads to:
Unforeseen system conflicts that disrupt order processing and fulfillment
Data silos that cause order, inventory, and customer data inconsistencies
Missed automation opportunities due to incomplete or fragmented integrations
Higher integration costs from avoidable development rework
By taking the time to assess your system architecture and define your integration use cases, you can avoid costly delays, ensure seamless data flow, and create a more scalable business.
Step 1: Assess Your Current System Landscape
Before integrating a new vendor, it’s critical to map out your existing technology stack and understand how different systems interact. Without this step, integrations often fail because they don’t account for hidden dependencies, outdated workflows, or missing data connections.
What to Assess in Your Current Setup
E-Commerce Platform (Front End)
Where do orders originate? (Shopify, Magento, Salesforce Commerce Cloud, etc.)
Are there multiple sales channels? (Amazon, eBay, social commerce)
Middleware & Integration Layers
Do you use API gateways, iPaaS platforms (MuleSoft, Boomi, Workato), or custom connectors?
How do data transfers between systems currently work? (Batch vs. real-time sync)
Back-End Systems
ERP (Enterprise Resource Planning): Manages inventory, pricing, and financials
OMS (Order Management System): Routes orders to fulfillment centers
CRM & Marketing Platforms: Customer segmentation, loyalty programs, and email campaigns
Fulfillment & Logistics
WMS (Warehouse Management System): Handles inventory tracking and fulfillment
3PL (Third-Party Logistics) & Shipping Carriers: How do they receive order data?
How to Visualize Your System Landscape
To get a clear picture of your current setup, create a system architecture diagram that maps:
All platforms and services in use
How they connect and exchange data
Any middleware or custom APIs in place
Why It Matters: Having this high-level view prevents unexpected roadblocks and ensures that a new vendor can integrate smoothly with existing workflows, rather than disrupting them. |
Step 2: Identify Business Use Cases That the Integration Must Support
Even if a vendor provides standard integration features, they may not align with your actual business needs. Instead of focusing only on whether a system “connects,” brands need to identify real-world use cases that the integration must handle.
Key Questions to Define Use Cases
Order Processing & Fulfillment:
Will orders be fulfilled in-house, through a 3PL, or both?
How should split shipments be handled?
Customer & Marketing Data:
How will customer profiles sync between Shopify, CRM, and marketing automation tools?
Will your loyalty and rewards program be affected?
Do you need regional pricing and multi-currency support?
Returns, Refunds & Compliance:
How do return requests sync across Shopify, OMS, WMS, and payment processors?
Are taxes and compliance regulations correctly accounted for?
Why business use cases matter: many brands test integrations using basic order processing, but don’t consider complex edge cases. This leads to unexpected failures after launch, requiring expensive fixes. Best Practice: Work with operations, finance, and customer service teams to define real-world workflows that need to be tested before integration is deployed. |
Step 3: Validate the Integration Against Your System & Business Needs
Once the system landscape and business use cases are mapped, brands should validate the integration against their specific needs before full implementation.
Key Steps in the Validation Process
Create a Sandbox Environment
Simulate real transactions in a test environment before rolling out changes to your live store.
Test Multiple Order Scenarios
Standard orders, high-volume checkouts, split shipments, international orders.
Simulate Peak Sales Events
Ensure the integration can handle flash sales, holiday spikes, and sudden traffic surges.
Monitor Data Flow & Accuracy
Track order data from Shopify through to ERP, WMS, and fulfillment centers.
Final Check: Make sure that every use case identified in Step 2 is fully tested before the integration goes live.
Final Thoughts: A Strong Foundation Leads to a Seamless Integration
E-commerce brands often invest heavily in new vendors—ERPs, OMS, WMS, or fulfillment partners—but forget to assess their own system architecture and business workflows first. This leads to integration failures, operational inefficiencies, and unnecessary costs.
By taking the time to map your current landscape, define key business use cases, and validate the integration, you ensure a seamless transition, better automation, and a scalable e-commerce operation.
