Paleta
Custom management system (installable web app)
Screenshots come from the demo, with sample data. The demo runs on a free server, so the first load can take up to a minute.
01Context
Pinturería Cito runs two stores on a closed ERP for everything: sales, stock, pricing and invoicing. Paleta was born to handle the daily operation of both stores and, at the same time, as software any paint store can use.
02The problem
Checking whether a product is in the other store, selling quickly at the counter and updating hundreds of prices when a supplier list arrives were slow, error-prone tasks.
03The solution
A web system that installs like an app: a point of sale built for keyboard and barcode scanners, stock shared across branches, bulk price updates with preview and rollback, and per-user permissions with an activity log. Fiscal invoicing stays in the current system until an alternative is validated.
What's included
Counter
- Point of sale with barcode scanner support and keyboard shortcuts
- Offline sales that sync when the connection returns
- Quotes, returns and voided sales
- Daily cash register: opening, movements and closing

- Bulk price updates by brand, line, category or supplier, with preview, history and rollback
- Product import from Excel or CSV with validation
Management

- Reports on sales, gross profit, slow movers and inventory value, exportable to CSV
- Users with editable roles and permissions, plus an activity log

Design and technical decisions
- Installable web app (PWA) instead of desktop software: it runs on the counter PC and on phones, with nothing to install on each machine.
- The offline sales queue uses a unique ID per operation so a sale is never recorded twice.
- It coexists with the current fiscal system instead of replacing it all at once, which means less risk for the business.
- 76 automated tests against a real PostgreSQL database.
Not included (yet)
- Electronic invoicing (ARCA, Argentina's tax agency): for now the sale stores a reference to the invoice issued in the current system.
- Purchase orders to suppliers.
