ConsorcioNube — SaaS for Building & HOA Administration

The Challenge

Building administration in Argentina is still largely manual: monthly dues in Excel, payment validation over WhatsApp, maintenance claims with no follow-up, and documents scattered across email threads. The result is calculation errors, no audit trail, and inefficient communication between administrators and residents.

The Solution

ConsorcioNube is a multi-tenant system that digitizes every aspect of building management, with features designed specifically around the pain points of the Argentine market.

Core Features

- Dues Management: Creation, issuance and automatic per-unit calculation, with configurable early-payment discounts and professional PDF statements carrying a QR verification code.

- Payment System: Owners upload proof of payment; the administrator reviews and approves or rejects it. Every payment generates a signed digital receipt with a full audit trail.

- Tracked Maintenance Claims: Categorized tickets (maintenance, noise, cleaning, security) with priorities, statuses and comment threads for documented resolution.

- Amenity Bookings: Visual calendar for the common room, grill, pool and gym, with automatic confirmation.

- Multi-Role Portal: 5 distinct roles (SuperAdmin, Administrator, Building Manager, Owner, Tenant), each with its own views and permissions.

- Automated Communications: Transactional emails, a digital notice board, and real-time notifications.

- Digital Bookkeeping: Income and expense records, categorization, and Excel export for owners' meetings.

Tech Stack

Frontend: React 18 + TypeScript, Vite, TanStack Query, shadcn/ui (52+ components), Tailwind CSS
