E-commerce Order Processing Automation
An end-to-end order processing system that automates everything from order capture to customer notifications — built to eliminate the 15+ hours per week growing stores typically spend on manual fulfillment work.
The Challenge
Growing online stores commonly spend 15+ hours per week manually processing orders, updating inventory across platforms, and sending customer notifications. Manual processes like these are error-prone, delay fulfillment, and put a hard ceiling on how many orders a small team can handle.
The Solution
A comprehensive n8n workflow that automatically processes orders from Shopify, updates inventory in a warehouse management system, generates shipping labels via ShipStation, and sends personalized customer notifications at each stage of fulfillment — all without human intervention.

How I Approach a Build Like This
- Thorough Process Mapping: Understanding every step of the existing workflow before automating anything
- Stakeholder Input: Involving the people who do the work today — they know where the edge cases are
- Phased Rollout: Testing with a subset of orders before full deployment
- Documentation: Clear runbooks so your team can operate and extend the system confidently
