WMS
TubWorks WMS
An end-to-end warehouse management system that turns Shopify orders into organized pick waves, verifies every item with barcode scanning, and buys the cheapest valid shipping label at pack time.
The Challenge
A growing product business needed its warehouse to keep up with Shopify order volume without mis-ships, wasted walking time, or overspending on shipping.
The Problem
Orders were picked and packed manually. Items were checked by eye, pickers walked the warehouse inefficiently, and shipping labels were bought without comparing carrier rates — so mistakes and shipping costs grew with volume.
The Solution
Zuvel built a warehouse management system that ingests Shopify orders automatically, groups them into pick waves organized by warehouse location, verifies every item at barcode packing stations, and compares live carrier rates to buy the cheapest valid label at ship time.
Key Capabilities
What the system actually does.
- 01
Order Ingestion
Flow Shopify orders into the warehouse automatically as they are placed — no manual order entry.
- 02
Pick Wave Generation
Group orders into pick waves organized by warehouse location to cut walking time.
- 03
Barcode Packing Stations
Scan and verify every item at pack time so mis-ships are caught before dispatch.
- 04
Carrier Rate Shopping
Compare live carrier rates per parcel and select the cheapest valid service automatically.
- 05
Label Purchase & Manifest
Buy and manifest shipping labels directly from the packing station.
- 06
Operations Dashboard
See warehouse throughput, open waves, and shipping status in one operational view.
Engineering Challenges
The hard parts, handled.
- 01
Shopify Order Ingestion
Flowing orders into the warehouse automatically and reliably as they are placed.
- 02
Pick Wave Generation
Grouping orders into pick waves organized by warehouse location to cut walking time.
- 03
Barcode Scanning Workflows
Verifying every item at pack time so mis-ships are caught before dispatch.
- 04
Carrier Rate Shopping
Comparing live carrier rates per parcel and purchasing the cheapest valid label directly from the packing station.
Outcome
The warehouse runs from one system: orders flow in automatically, pickers follow organized waves, every packed item is scan-verified, and shipping labels are bought at the best available rate. Fulfillment mistakes are caught before dispatch instead of after delivery.
