Built for pool pros, by a small team in Pennsylvania.

Waterline is a CRM made for pool builders, service companies and spa dealers, and Marco is its free app for the pool owners they serve. Pool companies run their jobs in Waterline; owners care for their water and follow their jobs in Marco.

Both are built by TriLumen Systems, an independent software company in northeastern Pennsylvania that also makes PermitLogic, the CRM for contractors.
