Why Construction Estimating Still Runs on Spreadsheets — and What We Built Instead
The $13 trillion industry with a spreadsheet problem
Construction is one of the largest industries on the planet. Yet when it comes to managing budgets, most contractors still do it the same way they did fifteen years ago — in spreadsheet files shared through messaging apps.
A foreman gets a call: "How much for a 2-bedroom apartment renovation?" He opens a spreadsheet from his last project, changes a few numbers, exports a PDF, and sends it to the client. The client asks for changes — back to the spreadsheet. Materials? He calls the supplier. Schedule? In his head. Budget tracking? A notebook or, at best, a separate file he'll forget to update.
This isn't a technology problem. Tools exist. The problem is that none of them were built for the people who actually run construction sites.
What exists — and why it doesn't work
Government estimating software like AVK-5 or similar state-standard tools is designed for large tenders and procurement, not for a contractor renovating apartments. The interface alone takes weeks to learn. The output formats are built for bureaucrats, not clients.
Generic project management tools — Monday, Asana, Notion — know nothing about construction. They can't calculate material quantities, don't understand the difference between work pricing and client pricing, and have no concept of construction phases.
Enterprise construction platforms like Procore, Buildertrend, or PlanSwift are powerful but designed for US general contractors managing million-dollar projects. They cost $300–1000/month, require training, and assume workflows that don't exist in most renovation markets.
The result? Contractors in markets like Ukraine, Poland, Turkey, and dozens of other countries keep using spreadsheets. Not because they want to — because nothing else fits.
What we built
LIHTAR is a web platform that combines construction estimates, material calculations, scheduling, and client communication in one place.
Here's what makes it different:
Dual pricing that protects your margin. Every estimate item has two prices — your actual cost and what the client sees. The markup percentage applies automatically. The client views their version through a shared link. Your real numbers stay hidden.
Material calculations based on real specs, not AI guesses. We built 80+ technical calculation cards — for screeds, plaster, drywall partitions, tiling, masonry, and more. Each one follows manufacturer specifications from Knauf, AEROC, Ytong, and others. You enter room dimensions and the type of work — the system calculates exact quantities including consumables like primer, tape, screws, and mesh. These aren't generic estimates. They are engineering models built from 20+ years of hands-on construction experience.
800+ prices in a live directory. Market prices for construction work, updated monthly. When you type a position name, the system suggests prices from the directory. You can also maintain your own private price list and share it with clients as a branded PDF.
50+ ready-made templates. Bathroom renovation, electrical work, plastering, demolition — add an entire scope of work to your estimate with one click. Templates are built by practicing contractors, not generated by AI.
Gantt chart with subcontractors. Link estimate items to tasks on a timeline. Assign subcontractors. The client can view the schedule through their shared link.
AI import. Paste text from a messenger, upload a PDF, Excel, or Word file — the system recognizes items, quantities, and prices in seconds. This turns a messy WhatsApp message into a structured estimate without manual entry.
Tenders. Publish your estimate and let subcontractors submit competing prices. Closed tenders for your trusted contractors, or open tenders for anyone.
Works on your phone. The entire platform is mobile-responsive. Add it to your home screen and use it like a native app.
The numbers so far
We launched in February 2026, focused on the Ukrainian market. Within six weeks, over 100 contractors signed up — without paid influencers, without viral campaigns. Just Google Ads targeting people searching for "construction estimate online" and organic word of mouth from foremen showing the tool to colleagues on job sites.
The pricing: free plan that lets you manage one project forever. PRO at $7.50/month (300 UAH) — unlimited projects, AI import, tenders, branded exports, client portal. In a market where the closest competitor charges $25–50/month for a fraction of the features, this was a deliberate choice.
What's next
We're working on a drawing reader that will analyze architectural blueprints and extract quantities directly into estimates — rooms, walls, openings, floor areas. No manual measurements. This will connect directly to the material calculation engine, creating a pipeline from blueprint to fully calculated material list.
We're also building an open tenders marketplace where any contractor can find and bid on projects, and deeper integration with material suppliers for direct ordering.
