Construction estimating software with custom cost database, digital takeoffs, and proposal-ready exports; built for contractors who need accurate bids without the bloat.
KonBid is construction estimating software built for contractors and estimators who need to turn around bids without burning out. It serves general contracting, excavation, sitework, utility, concrete, asphalt, septic, land clearing, landscape, and hardscape contractors with digital takeoffs, a custom cost database, and proposal-ready exports in one tool.
Every feature exists because a real contractor asked for it. Every default is set the way you'd set it yourself. No fluff. No bloat.
KonBid takes a bid from PDF plans to a finished proposal in one workflow. Estimates, takeoffs, on-site measurements, cost database, cut & fill, summaries, exports, and presets - the screens you work in every day, connected so quantities, pricing, and documents never need to be retyped.
Line items, assemblies, crews, and markups in one live estimate, so your number updates as you work.
Length, area, volume, and counts flow from the plan into your estimate, no double entry, no spreadsheet middleman.
Enter lengths, areas, volumes, and counts from measurements you took on site, no plan PDF required, and push them straight into the estimate.
Build and maintain a proprietary cost database - materials, labor, and equipment rates specific to your crews and region. Build powerful assemblies to price tasks even faster. See the construction estimating software →
Calculate cut, fill, and net dirt volumes from the plan, then push those quantities straight into the estimate.
Direct costs, markups, and bid price roll up clearly, so you know your margin before you hit send.
Branded PDFs and polished exports generated straight from the estimate, not rebuilt in Word the night before.
Save estimate and bid templates once, then spin up the next job from a proven baseline instead of a blank page.
Tools built around the way real estimators work -> from the cost database to the final proposal. KonBid includes a custom cost database, assemblies, crews and production rates, integrated digital takeoff software, cut and fill, proposal exports, change orders, pipeline tracking, and unlimited templates in one flat $79/month plan.

Generate professional change orders instantly. Track revision history, apply any changes, and export documents for signing without starting from scratch.

Your estimates sync across every device. Start a takeoff on the field laptop, finish pricing at the office. Always ready for you.

Estimating doesn't need to be overcomplicated or time-consuming. KonBid replaces the calculator, the spreadsheet, the old bid you copy-paste from, and the Word proposal with one connected workflow: automated calculations from takeoff, instant cost database search, templates, branded exports, and change orders with revision history.
Real estimators. Real construction companies. Real numbers. Contractors using KonBid say the biggest wins are measuring plans and sending costs straight to the estimate, reusable assemblies that turn most bids into a few clicks, and clean change orders built from the original bid.

"The time we save from quickly measuring plans, and sending costs directly to the estimate pays for the software itself. We're done with spreadsheets and retyping bids."
"Being able to create and reuse assemblies for my different tasks has been a game changer. It saves so much time on the estimating side, a lot of my estimates have just become choosing a couple assemblies and done."
"Change orders used to be a nightmare for us. Now I make them in KonBid, send a clean PDF, and get signatures squared away easily. I used to type up change orders manually for everything, this program just makes them from my original bid."
