Construction Quotation Engine
A structured quotation system that turns project specifications into material quantities, labour planning, commercial terms, payment milestones, and a client-ready proposal.
The operating problem
A serious quotation is a connected commercial model, not a formatted spreadsheet.
Construction estimates combine area, floors, structural assumptions, finish tiers, material rates, labour, taxes, payment stages, and client terms. Manual revisions make it easy for one change to leave the rest of the document inconsistent.
The engine structures those inputs into a repeatable five-step workflow and carries them through pricing, quantities, presentation, and client review.
Product workflow
One project definition drives the commercial document and its supporting detail.
Select specifications
Choose a material tier, swap individual materials, and apply firm-specific rate overrides.
Calculate scope
Generate the material BOQ, labour, taxes, statutory charges, and milestone schedule.
Present and approve
Share a client portal, export a PDF, track review status, and record acceptance.
01 / Material intelligence
The estimate remains connected to measurable quantities.
The BOQ view exposes material quantities by project configuration, including structural dimensions and room counts. It gives procurement a usable basis instead of hiding the calculation inside a single rate.
02 / Client review
The client sees a controlled proposal, not the internal workspace.
Secure share links separate the client-facing quotation from firm administration. The portal presents the summary, cost breakdown, payment schedule, PDF download, and sign-and-accept flow in a focused review experience.
Build evidence
The source covers the calculation, operating workflow, and client handoff.
The application workspace includes the five-step wizard, firm-scoped data, material logic, BOQ, labour and payment modules, document export, presentation mode, and client portal.
- Six material tiers with item-level swaps and rate updates
- Indian land units and project-area conversion
- GST, TDS, BOCW, RERA, and nineteen payment milestones
- Material BOQ, labour attendance, and payment tracking
- PDF export, secure share link, and acceptance workflow
- Next.js, TypeScript, Prisma, and authenticated firm scope
Scope and verification
A functional MVP with production dependencies stated plainly.
Registration, firm-scoped quotations, live pricing, BOQ, labour, payments, PDF export, client review, and acceptance are documented as working in the source workspace.
Automated email, WhatsApp communication, voice calls, and scheduled jobs require external service configuration before production use.
The SQLite MVP should move to a production database, shared material mutation should be isolated, and revision history plus multi-user invitations should be completed.
