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.
