Most estimating software is built by software people for software people. Klorra was built by builders — by the estimators and project managers doing the work.
The math was the problem: 25–35 hours of senior time per bid, 40+ bids a year, and most never become jobs. That's a year of senior labor lost to projects that walk away.
The fix was a 7-phase AI pipeline that reads the plans, flags conflicts on and between plans, runs the takeoff, prices 160+ cost codes, writes the scope, and audits the output before delivery. The cost-code logic and estimating discipline came out of years of bidding our own custom homes; the AI pipeline was built on top of it in 2026 and runs our own bids today. Now it's open to other builders.
Klorra delivers the same finished bid we'd produce for ourselves — in 4 hours, at a fraction of the cost.

Every SF, LF, opening, and unit counted. Each line item anchored to a specific sheet in your plan set so you can audit any quantity back to its source.
160+ trade-organized cost codes priced. Override discipline logged on every adjusted unit price.
Client-ready scope organized by trade category, with the front elevation from your plans. Drop-in formatted for your contract package.
Cross-discipline clashes, code issues, and items requiring architect or engineer clarification — flagged before you bid, ready to send back for resolution.
What the QC pass flagged for you to confirm before you contract: low-confidence quantities, overrides worth a second look, open questions. Nothing hidden.
A full takeoff and budget for a 4,000 SF custom home eats 20–40 hours of senior time. Most builders do it on nights and weekends.
Hire one full-time and you can't keep them busy. Hire one part-time and you lose continuity. Most $2–20M builders go without.
Your real cost-per-win is the cost of every bid you produced — including the ones you lost. Most builders never compute this number.
No software to install. No takeoff training. No clicks to count.
Drag in your architectural plan PDF. Answer a few quick intake questions about lot, finish level, and region. About 5 minutes.
A 7-phase AI pipeline reads every sheet, flags conflicts, runs the takeoff, prices 160+ cost codes, writes the scope of work, and runs an automated QC pass before delivery. You review the output and adapt to your subs and suppliers before commercial use.
You receive an Excel takeoff and cost estimate, a client-ready scope of work, the conflict report, and verification notes, ready to send. Need a change? Request a revision from the bid page and we reply directly.
Move the sliders. The number gets uncomfortable fast.
Most estimates spit out a number. Klorra gives you a budget format that survives the project — built on six principles we'd defend to any working builder. Three of the most important below.
Every Klorra Scope of Work is organized the way the job gets built — trade by trade, from pre-construction and site work through finishes — and every scope line traces to a cost code in the estimate. Subs find their section and bid against it directly. No translation layer between the estimate and the SOW, no reorganizing for the contract package, no explaining why the two documents don't match.
Every line item references a specific sheet on the plan set. No phantom quantities. If a number can't be traced back to a sheet, it doesn't go in the bid. This is the discipline that stops the failure mode that punishes builders six months into a job — when an unanchored estimate runs into a real plan set on a real job site.
Takeoff and pricing are separate stages, on purpose. Phase 2 produces verified quantities anchored to plan sheets. Phase 4 prices them. The quantities are reusable across pricing scenarios — change a labor rate or material cost and the whole bid recalculates without re-running takeoff. Most software conflates the two; we keep them clean.
Three tiers based on how often you bid. Annual or monthly billing — your call. First takeoff is free regardless of which you pick.
Or pay as you go: $299 per bid, no subscription. Your first bid is always free.
Bid it out: Klo sends your requests for bid, chases the subs, reads every proposal and levels the numbers. You pay once per job. Pay-as-you-go $199 per job. One charge per job, taken the first time you send requests for bid on it. It covers that job for 90 days: every trade package, reminders, Klo reading proposals, leveling, follow-ups, and re-sends after plan changes. Sending yourself a test is always free. On annual plans, the monthly inclusion applies in every month of your term. Details.
Klorra deliverables are budgeting and planning tools, not warranted bids. Every quantity and rate is the builder's responsibility to verify before commercial use. Terms §3.
Everything about sending one job out to bid, for 90 days from the first request: all trade packages, reminders to subs, Klo reading the proposals that come back, the side-by-side leveling, and follow-ups when the scope or plans change. You pay once for the job, not per package or per sub.
You're only charged when the first request actually goes out. Sending yourself a test is free.
Yes — end-to-end. The pipeline reads the plans, flags conflicts, runs the takeoff, prices 160+ cost codes, writes the scope of work, and runs an automated QC pass whose findings ship to you as Verification Notes. No human edits the bid before it reaches you. The accuracy disclaimer is in plain English in our Terms — verify every quantity against your own takeoff before commercial use. First bid is on us so you can test before you trust.
Klorra was built by builders — people who were already producing takeoffs and estimates on real projects inside an active custom home builder. The cost-code logic, override discipline, and QC checks come straight out of a builder's processes and procedures — not a software shop guessing at how a builder thinks. The point isn't blind trust; it's that the output looks like something a working estimator would produce, and you can pressure-test it against your own numbers.
Plans are stored encrypted at rest and in transit, in U.S. data centers, and visible only to authorized users on your account. We do not sell or share personal information for advertising. Our AI inference provider's commercial API terms applicable to Klorra do not use customer prompts or completions to train foundation models. We may use anonymized, aggregated metrics for product analytics and product improvement. No system is perfectly secure and we don't warrant security — full detail in the Privacy Policy.
Those are software you operate to do your own takeoff. Klorra delivers the takeoff. They charge you to learn a tool; we hand you a finished package — Quantity Takeoff, Cost Estimate, Scope of Work, Conflict Report, Verification Notes — that you review and adapt. If you've wanted to save the time and headache of running your own takeoffs, this is for you.
Klorra delivers a rigorous takeoff — every SF, LF, and opening counted — and a cost estimate built on regional reference rates, with the same cost-code discipline a senior estimator would apply. Like any tool, you should verify the numbers against your own subs, suppliers, and recent project data before you contract — regional pricing varies, and your specific relationships will produce your specific numbers.
Subscriptions cancel any time, effective at the end of the current billing period — you keep access through the period you've paid for, but there's no proration or partial refund. Pay-as-you-go bid fees are non-refundable once submitted. Klorra may issue a discretionary credit for a confirmed service failure or billing error, but that's a courtesy, not an entitlement.
Typical turnaround is under 4 hours, and that's what we aim for on every bid. It is not a contractual SLA — we don't guarantee uptime, availability, or delivery time.
