A market growing at ten percent a year, still running on email
Estimating software is heading for $1.72 billion in 2026 and compounding at roughly ten percent. Bid day, for most subcontractors, is still an inbox and a spreadsheet.
There is more software sold into estimating every year, and the daily experience of running a bid has barely changed.
The spend is real and the tools are good. Takeoff is digital. Cost data is licensed. Bid boards aggregate invitations that used to arrive by fax. Every individual link in the chain has been modernised.
The chain is what did not get built
An invitation lands in a mailbox. Documents get pulled into a share drive. Takeoff happens in one system, pricing in a second, vendor solicitation in a third, and the proposal is assembled by hand from all of them. The connective tissue between good tools is a person copying values between them under time pressure.
Every link in the chain got modernised. The chain did not.
The friction shows up on the other side too. Response rates to bid invitations sit somewhere in the region of nine to fifteen percent, which tells you how much solicitation effort produces nothing at all.
Why the seam is where the loss is
Mistakes cluster at handoffs. A number retyped from a quote into a workbook. A late addendum that reached the folder but not the person doing pricing. An exclusion noticed during leveling and never carried into the proposal.
None of these are failures of the individual tools. They are failures of the space between them, which is exactly the space no vendor was selling into.
What we are actually building
ArosBid does not replace your takeoff, your cost data, or your accounting. It runs the pursuit that connects them, and it keeps a record of every decision made along the way, so the seam stops being where the money goes.
The market data says the category is growing. The workflow data says the growth has not reached bid day yet.
