Question for Park Owners

[Eric S.]

My company owns a couple very small parks that we manage ourselves. In the past we've included water bills in our lot rent, as we don't have many tenants and it's just easier, but recently the small towns we are in have raised their water and sewer rates so high that it's eating us alive and we are looking into sub metering. I'm not worried about finding the meters themselves, I'm more worried about getting the right software to track water usage and make invoices for the tenants so that I can waste as little time as possible on the bookkeeping. Anyone have experience with this type of thing and can maybe recommend the best software for tracking and creating invoices?
