Most estimating software is a four-month rollout. We're a five-minute upload.

What you don't have to do

Six demands every estimating software makes.
We skipped them all.

What contractors told us

They tried the software.
They went back to Excel.

Mark estimates commercial in CSI divisions. Matt runs labor-heavy environmental work by man-hours. Chauncey works backward from a gut-feel target on residential builds. Three different pricing systems. Same answer when we asked what they use today.

2-4 hrs
"to work up a rough budget. If you had an assembly maybe an hour." Mark, 25-yr commercial estimator

"It's generally not very accurate."

Mark on RS Means. Generic cost databases miss your markups, your vendors, your county-level pricing. They're a last resort, not a foundation.

"It would be August before we're ready."

Matt on BQE. Enterprise tools cost $40K/year and take four to eight months to onboard. By the time you finish, your data is already stale.

"You're fixing to get clocked."

Matt, on missing man-hours. Excel doesn't catch what you forgot. Glass up $26K in 60 days. Every miss comes straight off your margin.

"$800 here. $3,800 closer to the city."

Chauncey, central Mississippi. Same line item, 50 miles apart. Off-the-shelf databases can't price your county. Your context lives in your past bids.

"You always feel like you're missing something."

Matt, on what makes him second-guess a bid before it goes out. "When it's a competitive bid, you have a little bit of butterflies about your number." That's what BidFlow is built to take off the table.

The line that sums up everything we're building

The spreadsheet needs to work for you. Not you working for the spreadsheet.
