BUILDSQUARE – Construction Marketplace + Project Management + B2B SaaS Platform Project Overview We are building BUILDSQUARE, a next-generation digital platform for the construction industry in India. Our vision is to create one integrated ecosystem where property owners, builders, contractors, architects, engineers, vendors and construction-material suppliers can connect, manage projects, compare quotations, procure materials and manage construction activities digitally. BUILDSQUARE will combine: Construction Marketplace + Material Commerce + Project Management + B2B SaaS + AI We are looking for an experienced full-stack developer or development team who can help us build the MVP and potentially continue as a long-term technology partner. Our Vision The initial focus will be on launching in one city in Odisha, validating the business model, and then expanding across Odisha and eventually throughout India. The platform should be designed from the beginning with scalability, security and future integrations in mind. Core Platform Modules 1. Customer Platform Customers should be able to: * Create an account and profile * Add property/project details * Post construction requirements * Find architects, contractors and service providers * Request quotations * Compare quotations * Select vendors * Manage project progress * Communicate with vendors * Track project expenses * Receive notifications and reminders 2. Professional & Vendor Marketplace Vendor categories may include: * Architects * Civil Engineers * Contractors * Vastu Consultants * Interior Designers * Fabrication companies * Construction-material suppliers * Equipment rental companies * Solar companies * Security providers * Project-management professionals Vendors should have: * Professional profile * Business information * Service categories * Location coverage * Portfolio * Ratings/reviews * Verification status * Quotations * Lead management * Customer communication 3.

Equipment Rental The platform should support construction equipment rental, including: * JCB * Excavators * Cranes * Concrete mixers * Scaffolding * Other construction equipment Features should include availability, pricing, booking/request, vendor management and location. 5.

“BUILDSQUARE – Build Better Together Hello! As per your project post, you are looking to build BUILDSQUARE Construction Digital Marketplace that connects property owners with architects, contractors, engineers, vendors, suppliers, and equipment providers. The MVP will bring together professional discovery, quotation and BOQ management, project tracking, construction services, and an administrative platform, with the initial launch focused on validating the model in one city in Odisha before expanding across the state and India. I can help build the MVP with a scalable architecture covering customer accounts, professional profiles, vendor verification, service discovery, quotation requests, quotation comparison, BOQs, communication, project milestones, expenses, documents, photos, notifications, and admin management. The construction marketplace can also be structured to support materials and equipment rental. I would also design the foundation with your future B2B SaaS model in mind, allowing modules such as CRM, lead management, invoicing, inventory, project management, employee management, analytics, and AI assisted quotation analysis to be introduced without rebuilding the core platform. Let’s connect to discuss the first city, priority marketplace categories, and MVP workflows so we can build a focused first release while keeping the architecture ready for the larger BUILDSQUARE ecosystem.

BUILDSQUARE combines five products in one vision — marketplace, material commerce, project management, B2B SaaS and AI. The honest first observation: platforms this broad succeed or fail on sequencing, not on any single feature. Built all at once, nothing reaches quality; built in the right order, each module feeds the next. How I would approach it: - One shared foundation first: identity, organizations (owner / builder / contractor / architect / vendor as roles, not separate apps), and a single data model for projects. Every later module hangs off this, and it is the part that cannot be refactored cheaply later. - Then the marketplace core with quotation comparison — that is your acquisition engine and proves the two-sided market works before heavier modules are funded. - Material commerce and project management as the next phases on the same backbone, AI features last, where real data exists for them to work on. - Multi-tenant isolation enforced in the database, not application code: with competing contractors and vendors on one platform, a forgotten filter must return nothing rather than a rival's quotation. Proof: I digitalised a wholesaler end-to-end — B2B commerce, ordering, warehouse and delivery tooling, 18 services in production — plus multi-tenant platforms with database-enforced isolation. Questions: is there a written spec or wireframes, and which single module must launch first to win your initial users? Martin

Hi, We can build your construction marketplace with separate workflows for customers, contractors, and admin, using a scalable architecture. Two important questions: 1. Should customers directly book contractors or receive multiple quotes? 2. Are payments, commissions, and job tracking required in the MVP? Technical approach: 1. Customer App – registration, service search, contractor profiles, booking/quote requests, payments, chat, notifications, and reviews. 2. Contractor App – profile, verification, services, quote management, job requests, booking status, earnings, and notifications. 3. Backend – REST APIs, database, authentication, role-based access, validation, and secure data handling. 4. Admin Panel – users, contractors, verification, bookings, payments, commissions, disputes, and reports. 5. Integrations – payment gateway, maps, notifications, and required third-party APIs. 6. Delivery – testing, security checks, performance optimization, deployment, and complete source-code handover. What you get: Customer App, Contractor App, Admin Panel, Backend, Database, Integrations, Testing, Deployment, and Source Code. We have Full Stack, Flutter, UI/UX, QA, and DevOps resources available for complete project support. Best Regards, Nikhilesh Team Qloron

Hi — BUILDSQUARE is exactly the kind of multi-sided marketplace + SaaS platform I build. One ecosystem where owners, builders, contractors, architects, engineers and vendors each get a role-scoped experience: discovery/listings, RFQs and quotes, project workspaces, milestones and payments, plus an admin control plane. I'd architect it to scale from day one (clean services, Node.js APIs, a well-designed relational schema, caching and search). A platform this size succeeds or fails on sequencing, so I'd deliver in funded milestones against a signed-off scope: (1) architecture + designs + core auth/roles, (2) marketplace listings + RFQ/quote flow, (3) project management + milestones/payments, (4) admin, analytics and launch hardening — each with a staging build you review before we move on. This bid is a starting figure for phase one; we'll lock exact scope and a milestone schedule together. Can we jump on a call so I can map your must-haves for an MVP vs later phases?
