Tyler Technologies makes software used by local governments, courts and schools to manage administrative functions including property tax assessment, court case management, payroll and other public sector operations. Its software is deeply embedded in how many local government agencies conduct essential public administrative functions, since switching core government software systems is costly and operationally disruptive for public sector organizations with limited technology budgets and staff. Tyler Technologies primarily serves smaller local government entities like counties, cities and school districts rather than large federal agencies, a customer segment that often lacks the internal technology resources to build similar systems and instead relies on vendors like Tyler for essential administrative software. The company's revenue is largely recurring, tied to long-term contracts and subscription software licensing with its local government customer base, giving it a fairly predictable revenue model tied to the ongoing technology needs of public sector organizations.
