Your spreadsheet is silently eating your margin
Most contractors don't find out a job lost money until after the client has paid and the crew has moved on. By then, it's too late to fix.
Material prices swing
Lumber alone can move 15–20% in a few months. A static spreadsheet keeps your old prices — your estimate is wrong from day one.
Change orders slip away
Extra work gets done, never billed, and quietly erodes the profit you thought you'd made.
Committed costs go unseen
You close out a job, then a bill you forgot arrives. A real job costing tool tracks what's committed, not just what's spent.
One broken formula
Someone edits the wrong cell and 26 linked sheets fall apart. CostBolt keeps your data safe in a protected database.
Everything you need to track estimate vs. actual
The four cost categories every job needs — tracked in one place, in real time.
Line-item job costing
Break every job into labor, materials, equipment, and overhead. Compare each line's estimate against its actual cost while there's still time to course-correct.
Professional quotes
Turn any estimate into a client-ready PDF quote in one click — with your internal costs and markup hidden from the client.
Role-based access
Your foreman logs actual costs on-site without ever seeing your markup. Your client sees only final prices. Your margin stays yours.
Mobile-first
A responsive web app, not a cramped spreadsheet. Update costs from the truck, the site, or the kitchen table.
Profit dashboard
Work in hand, projected profit, and average margin across all jobs — updated automatically as you log costs.
Change order tracking
Log approved and pending changes against the original contract, so no extra work goes unbilled.
Three steps to predictable margins
Estimate
Build a line-item estimate with your labor rates, material costs, and markup.
Track
Log actual costs as they happen — from the site or the office — against each line.
Analyze
See your projected profit in real time and sharpen your next bid with real numbers.

Frequently asked questions
What is construction job costing?
Job costing assigns every labor, material, equipment, and overhead expense to a specific project, then compares those actual costs against your original estimate so you can see your true profit per job in real time.
How much does job costing software cost?
CostBolt starts at $19/month for solo contractors. Traditional construction accounting platforms typically start at $99–$199/month.
What costs should I track?
Track four categories on every job: labor, materials, equipment, and overhead. Missing any one of them makes your profit numbers wrong.
Does it work from my phone?
Yes. CostBolt is a responsive web app, so you can log costs from the job site on any device.
