Example inference
A Mercado Libre order for one unit from the FULL warehouse
FULL stock down by one, the sale costed, an audit entry and a restock check
Intended use
We import products from China and sell them on Mercado Libre and our own channels. That means tracking orders on their way, stock at home and in the FULL warehouse, every sale, shipment and landed cost. Spreadsheets only take you so far.
What it does
- Separate inventory for our own warehouse and Mercado Libre FULL, plus import orders still in transit.
- Marketplace order synchronization, shipments, stock loans and supplies.
- Restock suggestions for the next import, landed costs, auditing, push notifications and an AI chat interface.

Limitations and context
An internal tool built for the business I co-founded and run the tech for as CTO. Access is restricted, so the screenshots come from a local copy of the app filled with invented demo products. No real customer, financial or SKU data is shown.
