Overview
The Summary.
A US ecommerce fulfillment company needed to manage inventory across stores and coordinate orders with several shipping providers. Staff were moving between Shopify, Magento, and carrier tools, then printing labels manually. VARTEQ implemented a warehouse management system (WMS) that connected inventory, orders, and shipping in one place, reducing handling work and operating costs.
About the project. An ecommerce fulfillment company that manages store inventory, orders and carrier dispatch.
Engagement length. 6.5 months to delivery; development began 4 weeks after the agreement. Original plan: 7 months.
The challenge.
Client Requirements
- Compare carriers in real time to choose delivery options based on cost and speed.
- Manage inventory, orders, and quotations for Magento and Shopify stores from one platform.
- Replace manual label printing, which was delaying fulfillment.
- Connect shipping workflows to UPS, USPS, Endicia, and ShipStation.
Discovery Findings
- Separate systems were exchanging data poorly, causing inventory mismatches and fulfillment delays.
- Staff compared shipping options manually, slowing processing and increasing delivery costs.
- Label printing added manual work, errors, and delays to dispatch.
The solution.
- A WMS with shared inventory records, order processing, and shipping controls.
- Automatic comparison of carriers by delivery time and cost.
- Shipping label generation through the UPS, USPS, Endicia, and ShipStation APIs.
- Live order and inventory synchronization with Shopify and Magento.
The work covered the WMS, external connections, and deployment into warehouse operations:
- 01
System Development
- Designed the warehouse software for high order volumes.
- Built a shipping rate comparison engine.
- Automated order handling and label generation.
- 02
Integration and Testing
- Connected logistics services through web APIs to automate shipping.
- Linked Shopify and Magento for live order and inventory updates.
- Tested processing performance and reliability.
- 03
Deployment and Ongoing Improvements
- Introduced the system in stages to limit disruption to warehouse work.
- Trained staff and provided ongoing support as they adopted and refined the workflows.

Dataset task efficiency
A Shared Platform for Data Preparation and Model Training
Labeling requests, data collection, and model experiments were spread across tools with little consistency in how work was assigned or tracked. VARTEQ brought these activities into a data platform with a task marketplace, automated pipelines, and human review. Hypothesis validation costs fell by over 40%, while efficiency on dataset tasks improved by more than 60%.

Measuring Product Visibility in Advertising and Retail Displays
A US consumer goods company needed to measure how prominently its products appeared in video advertising and on store shelves. VARTEQ built a Product Recognition API using convolutional neural networks (CNNs) to detect placements automatically in real time. The resulting data helped the company assess marketing activity, allocate ad spending, and plan product positioning.
