About
BidVariance is browser-based Monte Carlo estimating software for consultants, agencies, engineering teams and specialist contractors pricing fixed-price work. Users build task-based models from optimistic, likely and pessimistic duration and cost estimates, connect task dependencies, and add probabilistic risks. The simulation engine samples thousands of outcomes and reports cost and schedule ranges, P50/P80/P90 results, loss and target-margin probabilities, deadline confidence, and the assumptions that drive variation. Users can test alternative scenarios on Business and Consultant licenses, calculate confidence-based quotes, export project data, and create printable decision reports. Project models stay in local browser storage; online license verification is required for the full workspace. Free standalone bid calculators are available without an account, while the multi-task simulation app requires a one-time license.

About
KonstructIQ is an AI-powered construction and financial platform designed for residential general contractors, remodeling firms, and home builders. It consolidates the full project lifecycle, from fast, professional estimates to budgeting, invoicing, payments, change-order management, cost tracking, subcontractor coordination, and real-time reporting, into a single interface. Its estimating module enables contractors to build detailed bids quickly, using customizable cost codes, markup or margin calculations, and either cost-plus or fixed-price models. Once an estimate is approved, it becomes the project budget; every subsequent bill, invoice, or change order automatically updates the budget so contractors maintain accurate job costing and profitability oversight. Payments to subcontractors or suppliers are built in, and support methods like ACH, checks, debit/credit cards, virtual cards, or Zelle, and invoices can be paid directly by clients through a portal to speed up cash flow.
