Plan takeoff vs. subcontractor bid

Your plans say 38 yards.
The bid says 44.

Subs pad quantities, and it’s brutal to catch by hand across a dozen trades. MemoryWell checks every bid against your takeoff and flags what’s over — before you cut the check.

Illustrative sample · your takeoff is the source of truth

One job. A dozen subs. Thousands of line-item quantities. Miss one padded number and it comes straight out of your margin — and you don’t find out until the job’s already built.

How the check works

Send the bid. It does the cross-check.

A small, deterministic workflow reads the bid, lines it up against your takeoff, and flags the gaps — with a human gate before anything is signed. It evaluates the files you already have. It never guesses a number.
