As a business owner, it's natural to want to supervise day-to-day business operations. However, since you have core business responsibilities you have to attend to, this isn't possible. Thankfully, just because you can't always be at your commercial premises doesn't mean you can't know what's happening in your offices and around your real estate's perimeters.
