| Scaling companies | Middleware |
| Enterprises | Custom API integration |
Choosing the wrong method causes syncing failures and data duplication.
Step 3 — Prepare Your ERP for E-Commerce Workflows
Configure your ERP modules:

Your ERP becomes the single source of truth.

Step 5 — Test the Integration
This is the most crucial step.
Test These Scenarios:
✔ Test order sync

Run at least 50–100 test orders to ensure stability.
Step 6 — Go Live & Monitor Performance
After testing:
