Pioneering the Future of Time & Billing System
2017
Introducing Expert Sierra V1— a cutting-edge cloud-based legal practice management solution tailored for law firms. Expert Sierra V1 empowered (and continues to) firms to seamlessly assemble, store, and manage financial data.
Featuring multi-tenant access, comprehensive billing and time tracking, enhanced team collaboration, task management, remote access, and robust reporting capabilities. This marked the start of the future of legal practice management: Expert Sierra
2020
As the demand for cloud-based solutions in law firms increased, so did Expert Sierra.
In 2020, Aderant launched Expert Sierra V2, introducing single-tenant access to ensure that firms can keep their data private, secure, and centralized in one dedicated cloud location. This release was complemented by Aderant’s migration process, which outlined clear steps for our existing Expert On-Prem clients to transition seamlessly to the cloud version of Expert Sierra. This process also supported On-Prem firms with other On-Prem systems, making the shift to the Expert Sierra cloud effortless.
2022
As cloud-based solutions became the standard for legal time and billing, Aderant elevated Expert Sierra by achieving SOC 2 certification.
This rigorous process demonstrates Aderant’s commitment to securely managing data and protecting client privacy. The certification involves a comprehensive audit by an independent third party to verify that Aderant met stringent security criteria.
