About the project
NEXO (RetailMind) is a complete ERP for multi-store retail: it brings point of sale, electronic billing, inventory, purchasing, analytics and AI into a single platform. Built to run store chains with full control and real-time data.
Point of sale (POS)
- Sales tickets with SKU product search and touch kiosk mode.
- Transbank card payments (official SDK, WebSocket and manual fallback).
- Cross-store returns and exchanges with authorization.
- Dynamic authorization codes (OTP) for sensitive operations.
- Daily cash reconciliation with fraud detection.
- Employee credit usable directly at the register.
Sales and tax documents
- DTE / SII issuance: receipts, invoices, dispatch notes and credit notes.
- Ticket-to-invoice conversion and parent-child document traceability.
- Bank deposits, DTE voiding and regularization, PDF/Excel export.
Inventory and purchasing
- Movements with 30+ concepts and FIFO lot costing.
- Cross-store transfers, adjustments and physical counts with recount and approval.
- Purchase orders, goods receipt with statuses and size-curve distribution.
- End-to-end product traceability.
Intelligence and analytics
- ML-powered purchasing prediction: ABC-XYZ classification, historical velocities and automatic suggestions.
- Size-break and slow-rotation alerts.
- 100+ reports and per-module KPI dashboards in real time.
