| | BidVariance | STACK |
|---|---|---|
| Score | 78.0 | 83.5 |
| Rank | #5 | #4 |
| Price | Free plan, paid upgrades | Subscription |
| Best for | Fixed-price bids that need a loss probability | Contractors and estimators who bid and run jobs in one tool |
| Digital takeoff from drawings | No | Yes |
| Monte Carlo simulation | Yes | No |
| Main users | Fixed-price project bids | Contractors and subcontractors |

Monte Carlo cost simulation that shows the probability of loss at a bid, with one-time paid licenses and free calculators. It models effort ranges rather than measured quantities, so the results depend on the ranges entered. Takeoff, estimating and proposals in one cloud product, with a field app that carries bids into project delivery. Per-user pricing makes it costlier for large estimating teams than narrower takeoff tools.
