One tool for every estimating stage

Estimate accuracy grows with the project. OneEstimate supports you from the first ballpark to the signed proposal.

Conceptual

Square-foot estimate

Start with lump-sum line items per square foot to give the owner a ballpark when there is only a schematic design.

  • Lump-sum items per SF
  • Reuse prices from past jobs
  • Cost range in minutes
Preliminary

Line-item estimate

Break the job into divisions and line items with quantities taken off the blueprint. Now you can compare design options.

  • Organized divisions and items
  • Quantities from the PDF plan
  • Compare scenarios
Detailed

Unit-cost estimate

Every line item with its unit cost breakdown: materials, labor, equipment and production rates. The foundation for confident bids.

  • AI-built cost breakdowns
  • Editable inputs and rates
  • Direct cost, overhead and profit
Cost analysis by input and category in OneEstimate estimating software

Why estimates miss and how to prevent it

Wrong quantities

You measure directly on the calibrated blueprint and every measurement feeds the line item, with no retyping.

Outdated prices

Update your cost catalog once and every estimate uses the same current price.

Missed scope

AI builds the full breakdown with materials, labor and equipment, so no input slips through.

Gut-feel markups

Set overhead, contingency and profit separately and see the final selling price before you send it.

From blueprint to proposal in 4 steps

1

Take off

Upload the PDF, calibrate the scale and measure areas, lengths and counts.

2

Estimate

Describe each activity and AI builds the breakdown with your catalog prices.

3

Adjust

Construction estimating questions

What is construction cost estimating software?
It is a tool to calculate what a project will cost before it is built: quantities, materials, labor, equipment, overhead and profit. OneEstimate does it in the cloud, with blueprint takeoff and AI-generated unit cost breakdowns.
What is the difference between an estimate and a bid?
The estimate is the calculation of the probable cost of the job, refined as the design progresses. The bid or proposal is the final priced document you send to the client. In OneEstimate the detailed estimate becomes your proposal directly, with no rework.
Can I do a quick square-foot estimate?
Yes. You can create lump-sum line items per square foot for a ballpark, then break them down into line items and cost breakdowns as more project information becomes available.
How accurate is AI estimating?
AI gives you a professional baseline breakdown with typical inputs and production rates. Final accuracy is yours: you adjust prices, rates and quantities to your job and market. AI removes the repetitive work, not your judgment.
Can I turn a quick estimate into a detailed one?
Yes. Start with a square-foot or line-item number and, inside the same project, replace those figures with unit cost breakdowns for materials, labor and equipment. You never have to rebuild the estimate from scratch.
How much does it cost?
Plans start at $49 USD/mo (PRO). BUSINESS is $99 USD/mo and GLOBAL is $179 USD/mo. AI usage requires additional credits.
