Completely understand. One of my clients is a geo survey/monitoring company. Their clients range across the world from quarries, mining, bridge and tunnel builders to name a few. No one online system does what they require and as a market the industry is too small for someone to develop such a specialised app. And using 10% of this app, 30% of that etc is just not a viable way to manage the business.online applications are very ineffective in getting through to our clients.
