Founded to fix a problem seen from the inside after 13+ years running a construction company: small issues on-site get missed, communication breaks down between contractor and client, and by the time problems surface they've become expensive claims instead of cheap fixes. siteMargin is a cost-tracking app built for contractors, developers, architects, interior designers and property owners, centered on four things: Cost tracking — know where the money's going on a project, in real time, not at month-end. Money saving — catch overruns early enough to actually do something about them. Issue prevention — flag problems while they're still small and cheap to fix, not three months later when they're a claim. Communication — keep every party on a project aligned throughout, instead of finding out where things stand only when something's gone wrong. Free to try on your first project. Available on Google Play now, with the App Store version coming online shortly.
