Built for the trade
Where a spreadsheet hits its limit
Spreadsheets are great at lots of things. These six situations are the ones that get harder every time the crew grows or the project count climbs. Steelplumb is what we built for those, while keeping the XLSX export your accountant already trusts.

One-click XLSX export. Same format your accountant already trusts.
What it looks like
Three screens cover ninety percent of a GC's estimating day, and every one of them already exports the XLSX your accountant still wants.

Active projects, total bid value, average margin, and cost-per-square-foot, without a single pivot table.

Edit line items inline. Catalog changes propagate. The whole crew sees the same numbers at the same time.

Ships with 86 CSI MasterFormat divisions tuned for Denver-region pricing. Adjust to your suppliers; estimates rebuild automatically.
Pricing
A 10-person GC pays five grand a year for RSMeans data their estimator stops opening in week two. Steelplumb ships with a good-enough catalog and the workflow layer that data alone can't give you.
One owner, three projects. The honest first step.
Your estimator, your PM, and you, all on the same page.
Multi-region operators and white-label proposals.
