What we build for construction companies

  • Proposals, RFPs and contracts.

    Generated from the bid's own data in your templates, then checked page by page before a rep sends them.

  • A way off PandaDoc and Google Drive.

    Your document history, templates and signing certificates moved into a platform you own.

  • CRM integration.

    One click on a deal creates the document, and its status flows back to the deal.

  • Prospect and bid signals.

    Weekly monitoring of target companies for contract awards, active sites and executive commentary.

  • Bid packages.

    Line items pulled out of solicitation documents, priced, and assembled into one PDF for a person to review and file.

  • Inspection and field forms.

    Forms built in the office and assigned to inspectors on site, in place of paper.

    OuterDocs: PandaDoc replaced for a US commercial contractor

    A commercial contractor with three brands ran proposals, RFPs and contracts across PandaDoc, Google Drive and a CRM that did not talk to each other. We built their own document platform. A rep gets a finished request for proposal from one click on a deal in about six minutes, and a person reads, edits and sends it.

    BuildWitt: buying signals for a construction training company

    Through the outbound agency Exploding Leads, a construction workforce-training company wanted to reach prospects before its competitors did. We built a pipeline that watches 600 target companies every week for new contract awards, active construction sites and executive commentary. Signals go out as outreach emails of 40 to 50 words, capped at ten a day.

For trades and field service companies

HVAC, plumbing, roofing and solar companies run on the same paperwork as contractors: quotes, proposals, follow-up and inspection forms. We scope that work from what we have built for commercial contractors.

Who does the work

4.9 out of 5 on Clutch

Full-time engineers and designers in our own office. No freelancers and no subcontractors. The senior engineer from your first call writes the code and stays on the project until handover. Our engineers build with Claude Code every day, and the products we deliver run on Claude, OpenAI's GPT models or Google's Gemini, chosen for the task.

Questions about construction software

Do you work with the tools we already use?

Yes. We have built on PandaDoc, Google Drive, Monday.com and a contractor's own CRM. We connect to what you have first.

Can you move us off PandaDoc?

Yes. For one contractor we moved 3,670 documents and 499 signing certificates into a platform they own, and proposals are now created there.

Will AI send proposals without anyone checking them?

No. The AI fills each document from the bid's own data and is not allowed to invent a number, date or address. A rep reads, edits and sends every document.

How long does a project take?

A fixed-scope project is quoted with its timeline before work starts. Larger builds ship in two-week sprints, with a demo at the end of each.

We are a small contractor. Is this for us?

Yes. Fixed-scope projects start at $1,500, and the first call is free.
