ServAura | Advanced On-Demand Service Booking Platform & Native App

Executive Overview & Platform Vision

Welcome to ServAura, a fully developed, rigorously tested, and ready-to-deploy enterprise on-demand service marketplace platform. By choosing our completed product, you bypass the massive risks, development delays, and uncertainties of building software from scratch. Our dual-native engineering teams focus entirely on customizing the platform to match your brand, integrating your local third-party APIs (like payment gateways and KYC tools), and deploying it directly to your dedicated servers and App Stores.

ServAura connects customers with trusted, background-verified service professionals and agencies. The platform handles everything from home maintenance, appliance repairs, and cleaning to personal grooming and smart living services. Operating on a fully managed marketplace model, it standardizes pricing, manages algorithmic dispatch based on live locations, securely handles digital escrow payments, and ensures end-to-end quality control.

Built using a 100% Free and Open-Source Software (FOSS) technology stack, this platform ensures you have zero recurring proprietary software licensing fees, making your business highly profitable and scalable from day one.

Platform Ecosystem & User Roles

Advanced Features & Technical Architecture

To ensure your platform stands out as a market leader, ServAura is pre-integrated with cutting-edge technologies that reduce operational costs and maximize customer satisfaction.

High-Impact & Future-Proof Features

Generative AI Voice Booking (Multilingual): Customers can tap a mic icon and speak in regional languages (e.g., "Please send someone to fix my AC tomorrow morning"). The AI engine processes the natural language to automatically select the right service, date, and time.
Vision-AI Auto-Diagnostics & Quoting: Customers upload a short video or picture of a broken appliance. The AI model identifies the issue and suggests the exact spare parts to the technician before they arrive, avoiding multiple trips.
AR (Augmented Reality) Space Scanner: For painting or deep cleaning, customers point their camera at the area. The AR integration calculates exact square footage for a 100% accurate price quote, eliminating bargaining.
IoT Smart Home Integration & Predictive Maintenance: Linked smart home appliances automatically send fault alerts to the ServAura app, prompting the customer to book a verified technician proactively.
Blockchain-Based Smart Contracts for Escrow Payments: The customer's payment is held in secure digital escrow and automatically released to the professional's wallet only when both parties verify the "Job Completion OTP."
Dual-Way Guardian Angel (Safety & SOS): Real-time GPS departure tracking monitors professional routes. A disguised one-touch SOS button immediately alerts your central operations hub with live location data for solo female customers and service professionals.
Dynamic Skill & Proximity Dispatch Engine: Assigns the absolute best professional within milliseconds based on live traffic speeds, current skill rating, battery level, and required spare parts.

100% Free & Open-Source Technical Stack

We built the architecture using robust open-source technologies to eliminate massive monthly bills for third-party services. Our Dual-Native Mobile Strategy harnesses the maximum potential of Apple and Google ecosystems.

Mobile Frontend: Native Android (Kotlin + Jetpack Compose) and Native iOS (Swift + SwiftUI).
Web Frontend: Next.js (React) + Tailwind CSS for an extremely fast, SEO-friendly application.
Backend Core: Node.js (NestJS) + TypeScript for secure, scalable enterprise logic.
High-Load Realtime: Go (Golang) + Centrifugo for live location tracking of thousands of technicians simultaneously.
Database & GIS Mapping: PostgreSQL 16 + PostGIS natively handles complex area maps.
Routing Engine (Maps): OpenStreetMap (OSM) + Valhalla (Self-hosted maps).
In-App Calling: Coturn (WebRTC) allows internet calls without sharing personal phone numbers.

End-to-End System Workflow

Search & Book: Customer selects a service, views transparent pricing, and chooses a time slot.
AI Dispatch: The system matches the job with the nearest top-rated, available professional.
Live Tracking: Customer views the professional travelling live on the map.
Secure Check-In: Professional arrives and enters a Start-OTP provided by the customer.
Service Execution: Professional adds necessary spare parts to the digital bill.
Sign-off & Payment: Customer provides Completion-OTP. Payment is automatically and safely transferred.
Ratings: Both parties rate each other to maintain high platform quality.

Commercials, Operational Costs & Timeline

Deploying a Dual-Native Mobile Strategy requires two separate engineering teams to customize our fully native apps in Kotlin for Android and Swift/SwiftUI for iOS.

A. Enterprise Setup, Customization & Deployment Cost (Indian Clients)

Description	Amount (INR)
Total Enterprise Setup Cost (Web, Backend, Native Android & iOS)	₹ 96,50,000
GST (18%)	₹ 17,37,000
Grand Total	₹ 1,13,87,000

B. Enterprise Setup, Customization & Deployment Cost (International Clients)

Description	Amount (USD)
Total Enterprise Setup Cost (Web, Backend, Native Android & iOS)	$115,000

C. Estimated Monthly Operational Costs (Third-Party)

Thanks to our open-source stack, monthly operational costs are drastically lower than industry standards.

Cloud Hosting: ~$250 - $500 USD / ₹20,000 - ₹40,000 INR per month (AWS or GCP, including load balancing and auto-scaling).
Messaging API (OTP/SMS): ~$30 - $50 USD / ₹2,500 - ₹4,000 INR per month (Usage-based).
Email Gateway (SMTP): Free up to 10,000 emails/month.

D. Client Customization & Post-Order Deployment Timeline

The core product is 100% complete, but enterprise-grade deployment requires extensive client-specific customization across three separate codebases. This branding, integration, and deployment project will be executed via intense, parallel engineering tracks over a 24-to-30-week timeline.

Maintenance, Support & Updates

First Year (Months 1-12): 100% FREE Maintenance and Support. Includes bug fixes, server monitoring, OS security patches, and Apple/Google OS compliance.
Second Year Onwards: Annual Maintenance Contract (AMC) available at 15% to 20% of the base project cost.
