The usual mess

What general contractors are stuck with

  • Jobs, crews and costs live in spreadsheets and group chats.
  • You learn a job lost money after it is invoiced.
  • Photos, change orders and warranties never land on the job record.

What changes

Outcomes on one system

  • One job record from estimate to invoice.
  • Field updates on Android and iPhone without a second system.
  • Margins visible before the job closes.

FAQ

Common questions

Do you build estimating software specifically for general contractors?

Yes. We scope estimating software around the workflows general contractor teams already use — then replace the spreadsheets and disconnected apps that hold them together. Jobs, crews and costs live in spreadsheets and group chats.

Can general contractors in California use this system?

Yes. We deliver for operators in California (United States) and the wider region. The system is owned by you, hosted where it fits your compliance needs, and shaped to local handoffs — not a one-size SaaS seat count.

What does a typical engagement look like?

A short discovery on how work moves today, a scoped first release, then weekly delivery until the team is running on the new system. Most first releases land in weeks, not a multi-year programme.

Who owns the software?

You do. Source code, hosting accounts and data are yours from day one, documented at handover. There is no seat licence and no fee that exists only to keep you with us.
