by OneAdvanced PR

Millar McCall Wylie is a leading full-service law firm based in Belfast, who has built a strong reputation for delivering high-quality legal services since its founding in 1997.
With a team of 65 staff and 11 directors, Millar McCall Wylie's success can be attributed to its commitment to innovation and customer satisfaction. The firm highlights the importance of adapting to changing client expectations and technological advancements; "We've always been focused on providing excellent service to our clients”.
As the firm continued to expand, it recognised the need for technology that could support more efficient operations, streamline case management, and allow its fee earners to focus more time on delivering value to clients.
By implementing OneAdvanced’s Practice and Case Management solution, Millar McCall Wylie has been able to centralise information, improve collaboration across teams, and drive greater efficiency throughout the firm.
The challenge: managing growth and increasing complexity
Like many growing law firms, Millar McCall Wylie faced the challenge of managing increasing volumes of client information, documents and cases. As the firm expanded its services and client base, it became increasingly important to ensure that staff could easily access information, collaborate effectively, and manage cases efficiently.
Without the right systems in place, administrative tasks and document management can consume valuable time for legal professionals.
The firm wanted a solution that would allow them to:
- Store and manage client information securely
- Improve document accessibility across the firm
- Streamline workflows and collaboration
- Support future growth and innovation
The Solution: implementing OneAdvanced Practice and Case Management
“Your Practice and Case Management software has been a game-changer for us.”
Millar McCall Wylie implemented OneAdvanced’s Practice and Case Management software in 2015, establishing a long-term partnership that has helped transform the way the firm manages its operations.
One of the core advantages of our solution is that it allows the firm to hold all its information in a structured, secure way, whilst making it easily accessible to all staff members. This saves the fee earners significant amounts of time, with everyone being able to easily retrieve and reuse documents. As a result, employees can quickly retrieve and reuse documents, reducing time spent searching for information and allowing them to focus on higher-value legal work.
The firm's experience with OneAdvanced has been overwhelmingly positive with the software being praised for its ease of use and excellent customer support: “The implementation process was seamless, and the support team has always been responsive to our needs.”
Embracing AI and future technologies
Millar McCall Wylie is now exploring the role of artificial intelligence (AI) in supporting legal workflows.
Initially, adoption within the firm was slow, but it has since seen growing enthusiasm as staff gain confidence in how the technology can enhance productivity. Through substantial training and support, employees are becoming more comfortable using AI tools, realising the value it holds in automating routine tasks and supporting their day-to-day legal work.
Culture that shines through
Millar McCall Wylie's commitment to innovation extends far beyond technology alone. The firm has a strong culture of inclusivity and teamwork, with a focus on staff well-being and community involvement.
"We pride ourselves on being a friendly and approachable firm, and it’s one of the things that makes us unique”
Operating from an open-plan office environment, the firm encourages teamwork, idea sharing, and open communication across all levels of the organisation. This culture has contributed to strong staff retention, with many employees building long-term careers at the firm.
Millar McCall Wylie is also committed to giving back to charity, supporting a different cause each year through fundraising initiatives, events and team activities both on and off-site, benefiting community engagement. This is just one of the many factors that see's them retaining legal professionals within the firm for many years.
