Castlethorn has delivered residential, commercial, and infrastructure projects across Ireland for more than 35 years. The organisation has steadily expanded its portfolio, adding new developments, new entities, and new layers of activity. As Castlethorn expanded its development portfolio and prepared for the next phase of growth, the finance team identified an opportunity to strengthen group-level reporting and improve the speed and integration of its planning processes. Solver Ireland supported this by building on the strong foundations already in place and delivering a more connected, scalable reporting environment.
The goal was simple: create a more connected reporting environment that could keep pace with the organisation’s growth and give the team clearer visibility without changing the way they already worked.
Castlethorn’s finance team operated with established processes and familiar tools. This approach had served them well for many years. But as the business broadened its development pipeline and added more parallel projects, the team recognised that a more integrated structure would help them work more efficiently and reduce the need for repeated consolidation work.
They wanted a way to maintain the rhythm of their existing workflows while gaining earlier insight across multiple entities. This wasn’t about starting over. It was about building on the systems already in place and shaping them into something more scalable.
To guide this phase, Castlethorn appointed a new CFO with strong experience in structured, multi-entity finance environments. He brought a clear view of how the function could continue developing its processes so that the team had the right set-up for a growing and increasingly complex portfolio.
Castlethorn was preparing for a new wave of activity. More projects were entering planning and delivery stages, and the finance team needed a reporting structure that could support these timelines without adding pressure.
The team wanted:
Nothing in the existing process was failing. The question was whether it could continue to support the pace of the business in the years ahead.
Solver became the preferred solution because it allowed the team to keep working in familiar tools while gaining the structure of a more modern reporting environment. What stood out was the practical way Solver Ireland approached the early conversations.
Rather than presenting abstract demos, the Solver Ireland team showed examples from real finance environments and practical outputs that aligned closely with what Castlethorn needed. This built confidence that the solution could deliver value early and without major disruption.
The decision to proceed was grounded in a shared understanding: strengthen the existing processes, introduce a more consistent group-level structure, and do so in a way that didn’t interrupt day-to-day work.
Solver Ireland delivered the project in clearly defined phases, each focused on giving the finance team more structure without increasing workload.
Key elements included:
As with any multi-entity setup, a few challenges appeared early on, such as data access delays and unlabelled databases. Because the scoping was comprehensive from the beginning, these issues didn’t derail the project. Timelines remained steady, and the team always had clarity on what was happening next.
Castlethorn now works within a more connected reporting environment that supports both immediate needs and longer-term planning.
The finance team can:
The team continues to use Excel where appropriate but now has a framework behind it that reduces duplication and strengthens oversight.
Several elements contributed to the success of this project:
This was not a reset of the finance environment. It was a structured development designed to support growth, improve visibility, and give the team a setup that fits the pace of the organisation.
Solver Ireland continues to partner with Castlethorn as new phases are planned and added, ensuring the reporting environment evolves in line with the organisation’s needs.
