JACK Reviews & Product Details

Built for builders, by builders. https://jackapp.io/us JACK is an all-in-one construction management platform that gives residential builders and contractors control over every job, from first estimate to final invoice. Built by people who have run building businesses, JACK replaces the spreadsheets, disconnected apps and paper trails that quietly erode margin on every project. Know your margin before you bid: Most builders find out a job was unprofitable long after it is finished. JACK's estimating and takeoff tools build accurate, itemised quotes from your own cost library, then track actual spend against that budget in real time. Purchase orders, variations, bills and progress claims all flow back to the job, so the margin you quoted is the margin you can see, live. One platform, not seven: - Estimating and takeoffs with reusable cost libraries and supplier pricing - Job management covering schedules, tasks, selections and specifications - Financials including budgets, purchase orders, variations, invoicing and cashflow forecasting - Site records through daily logs, photos and progress tracking - Trades and suppliers with RFQs, contractor management and job-level cost allocation - Timesheets and safety compliance captured on site, not retyped at the office - Client and lead management, so sales pipeline and delivery sit in one system Cashflow you can plan around: Cashflow is where many building businesses come unstuck. JACK models income and expenditure across your active jobs, so you can see what is coming in, what is going out and when, across the whole business rather than one project at a time. Built for the site, not just the office: The mobile app lets site teams log progress, capture photos, record hours and raise issues as they happen. Office staff get that information the same day instead of chasing it at week's end, and clients get updates that reflect reality. Who uses JACK: Residential builders, renovators, modular and prefab manufacturers, and specialist contractors, running anywhere from a handful of jobs to dozens of concurrent projects across multiple sites. Customers span Australia, New Zealand, the United States and Canada. Integrations and support: JACK integrates with Xero & QuickBooks so financial data moves between systems without double handling. Every subscription includes onboarding, account setup, full training, local support and ongoing updates. The result: Less admin, fewer surprises, and a clear view of profitability on every job. JACK gives builders the financial visibility large construction firms take for granted, in software designed for how building businesses actually run.
