Case Study
A supplier-catalog analysis workflow that turned days of marketplace research into a structured review completed in minutes.

The Challenge
Large supplier files required manual checks across prices, competition, marketplace fees, shipping, and fulfilment costs before the sourcing team could make a buying decision.
Individual supplier files could contain tens of thousands of products.
Pricing, competition, fees, shipping, and margin information had to be considered together.
A full catalog review could occupy the sourcing team for several days.
The Solution
Justo developed an analysis tool that imported supplier spreadsheets, matched products with marketplace listings, and calculated commercially useful pricing and margin signals.
Supplier CSV and XLS files could enter a repeatable analysis workflow.
Products were matched with relevant marketplace listings.
Competition, marketplace fees, shipping, and fulfilment costs were evaluated together.
The tool presented expected margin and a suitable selling price per product.
How We Built It

An import pipeline feeds normalized products into marketplace matching and cost analysis before producing product-level margin and pricing output.
The workflow was designed around the sourcing team's repeatable catalog-screening decisions rather than one-off spreadsheet checks.
The Results
A catalog that previously took more than three days to review could be checked in under five minutes, with hidden fulfilment costs included in the decision.
