KOSTN

KOSTN is a cost management platform for architects, project managers, general planners and construction teams who need more than static budgets and spreadsheets. It brings budgets, contracts, change orders, invoices, payment status and actual project progress into one consistent project cockpit. Teams can compare time, performance and billing progress, track commitments across multiple contracts, identify deviations early and keep financial decisions transparent throughout the project. Unlike traditional AVA software, KOSTN is focused on ongoing cost control rather than detailed tendering or item-based cost planning. It helps teams manage the financial reality between the original budget and the final account — including changes, additional costs, risks and shifting project conditions. Key features include cost planning, contract and change-order tracking, invoice management, performance monitoring, risk visibility and AI-assisted analysis. The goal is simple: fewer disconnected spreadsheets, earlier warning signs and a clearer picture of where the project really stands.
