STACK review

Takeoff-first, bid management barely described.

Verdict

STACK ranks seventh because it prices takeoff, estimating and field tools per user on a public page, but bid management appears only as a feature name with no separate price or description on the pages we opened.

What customers praise

Takeoff & Estimate starts at $299 per user per month with unlimited plans and projects, and the page says a free version is available. Build & Operate starts at $49 per user per month with a two-week free trial.

What customers criticise

The pricing page gives no separate price for bid management and says costs beyond the starting figures need a demo or the Build Your Price configurator. It describes no invitation tracking, leveling or prequalification, so the product scores low on the bid-specific criteria.

Best for

Estimators who need cloud takeoff and estimating first, with bid management as a listed feature, and who want a free version and published per-user starting prices.
