MILANSETU: Advanced Unified Matrimony, Dating, Live-in & Room Sharing Platform with Flutter Mobile App
Ready-to-Deploy Enterprise Platform Proposal & Technical Specification
(Includes Completed Next.js Web Application & Flutter Android/iOS Mobile Apps)
Executive Overview
We are pleased to present the proposal for MILANSETU, our fully developed, rigorously tested, and ready-to-deploy unified matrimony and dating platform. By choosing a completed enterprise product, you bypass the massive risks, delays, and uncertainties of building a complex system from scratch. Our engineering team will now focus entirely on customizing the platform to your brand, integrating your specific third-party APIs (like payment gateways and KYC providers), and deploying it to your dedicated servers and App Stores.
1. Commercials & Investment
Based on the latest market trends for enterprise-grade, scalable architectures (Web + Android + iOS + Backend), below is the detailed cost estimation for acquiring, customizing, and deploying our ready platform.
Technology Cost-Saving Advantage: This project is engineered utilizing 100% open-source and free-to-use technologies for the software stack. There are absolutely no recurring software licensing fees, proprietary database costs, or commercial framework subscriptions required to run this platform.
A. Platform License, Customization & Deployment Cost (Indian Clients)
| Description | Amount (INR) |
| Enterprise Setup & Customization Cost (Web, Backend, Flutter Android & iOS) | ₹ 14,50,000 |
| GST (18%) | ₹ 2,61,000 |
| Total Project Cost | ₹ 17,11,000 |
B. Platform License, Customization & Deployment Cost (International Clients)
| Description | Amount (USD) |
| Total Enterprise Setup & Customization Cost (Web, Backend, Flutter Android & iOS) | $22,500 |
C. Estimated Monthly Operational Costs (Third-Party)
While the core software framework is completely free and open-source, hosting infrastructure and third-party communication APIs require standard monthly operational budgets based on actual usage:
-
Cloud Hosting (AWS or GCP): ~$250 – $500 USD / ₹20,000 – ₹40,000 INR per month. (This is an estimated average for a standard enterprise deployment, including load balancing, managed PostgreSQL (RDS/Cloud SQL), auto-scaling compute instances, and object storage. Costs scale dynamically based on actual user traffic and data volume).
-
Messaging API (OTP/SMS): ~$30 – $50 USD / ₹2,500 – ₹4,000 INR per month. (Estimated for startup volume; billed per message by providers like MSG91 or Twilio).
-
Email Gateway (SMTP): Free up to 10,000 emails/month (via platforms like Brevo or SendGrid), and scalable thereafter.
D. Maintenance, Support & Updates
-
First Year (Months 1-12): 100% FREE Maintenance and Support (Included in the core cost). This includes routine bug fixes, server monitoring, and OS security patches.
-
Second Year Onwards: An Annual Maintenance Contract (AMC) is available at 15% to 20% of the base project cost. This covers ongoing updates, platform support, and technical maintenance.
2. Client Onboarding & Prerequisites

4. Legal Protections & Licensing
To protect the integrity of the source code and bespoke architecture, the project is governed by strict legal frameworks:
| Measure | Description |
| Master Service Agreement (MSA) | A strict MSA will be drafted explicitly defining severe financial penalties for reverse engineering, code extraction, or unauthorized distribution of the application. |
| Source Code Ownership | Associative retains full intellectual property (IP) and source code ownership of the core architecture until the final handover, as per the contract terms. |
| EULA & App Store Licensing | Using Apple App Store and Google Play EULAs, the app is legally licensed solely for the client’s specific brand and end-users. Repackaging, reselling, or white-labeling the application to third parties is strictly prohibited. |
| License Definition | Delivery is strictly classified as a “Single-Entity, Non-Transferable, Non-Sublicensable Lifetime License for Internal Business Operations.” |
| Compiled Binaries (Mobile) | Clients receive the compiled .apk / .aab (Android) and .ipa (iOS) binaries exclusively for their own business use. |
| Compiled Production Build (Web) | Clients receive the compiled, minified, and heavily obfuscated production build of the Next.js/React.js web application. The web source is strictly bound to the client’s authorized domain. |
| API Whitelisting & Obfuscation | Hardcoded, encrypted API tokens ensure the apps can only communicate with the client’s registered domain. Flutter binaries and React web builds are obfuscated to make reverse-engineering practically unfeasible. |
5. Technical Specification & Scope

8. Client Customization & Post-Order Finalization Timeline
Although the core product is 100% completed, an enterprise-grade deployment requires extensive client-specific customization. This includes applying your brand identity, integrating your local payment gateways/KYC providers, configuring AWS/GCP servers, and conducting rigorous QA testing before launch. The deployment will be executed over an 18-to-24-week timeline.
| Period | Phase | Activities |
| Weeks 1–4 | Requirements & Branding | Blueprint finalization, UI/UX brand integration, policy definitions, language planning, and AWS/GCP architecture design for your specific traffic needs. |
| Weeks 5–10 | Customization & Architecture | Core database structuring for your region, API endpoint configurations, Flutter & Next.js screen re-branding, and onboarding logic customization. |
| Weeks 11–16 | Integration & Core Setup | Client-specific OAuth, OTP, and KYC integrations, mapping APIs, configuration of Real-time WebRTC/Socket.IO features (Chat/Calls), Push Notifications, and AI matching logic setup. |
| Weeks 17–20 | QA & Testing | Multi-device UI testing on your branded apps, Web regression, API security testing, load testing on your AWS/GCP instances, optimization, and localization reviews. |
| Weeks 21–24 | UAT & Launch | Client User Acceptance Testing (UAT), critical deployment fixes, final production server go-live, and Apple App Store & Google Play Store submissions. |
