Network & Server Redesign for a Large CPA Firm

Case Study Image

Key Outcome Immediate performance relief + complete infrastructure redesign — eliminating daily disruptions during critical tax season

The Client

Our client is a large, well-established CPA firm serving a significant client base across the region. Their team relies heavily on specialized tax software — both in the office and remotely — to manage the high-volume, deadline-driven demands of the accounting profession. Like many firms of their size, they had built their server infrastructure over time, with additions and modifications made reactively rather than through deliberate architectural planning.

The firm reached out to Integrated Computer Services after their IT environment began seriously impeding their ability to work. Crippling slowness and instability when accessing their tax applications had become a daily obstacle, directly threatening their productivity and ability to serve clients during the critical tax season.

The Situation

When we engaged with the firm, the scope of the challenge became clear. Their server farm had grown organically over the years and was no longer architected to support the demands of their current team size or software stack. Staff were experiencing significant lag both locally and via remote access, and there was no quick administrative workaround available.

The firm needed a full infrastructure redesign — a new server architecture that would resolve the underlying performance and stability issues once and for all. However, they also needed relief immediately: waiting weeks for new hardware to arrive and be deployed was not an option for a firm dependent on meeting client and regulatory deadlines.

Our Solution

Integrated Computer Services launched a dual-track approach to address both the urgent performance issues and the long-term infrastructure needs simultaneously. Our projects team began scoping a comprehensive server refresh and network redesign, selecting hardware and architecture that would meet the firm’s current and future capacity requirements.

At the same time, our Tier 3 support engineers were assigned to dig into the existing environment — identifying configuration bottlenecks, inefficient resource allocation, and suboptimal network settings that could be corrected without any new hardware. Through targeted adjustments to their environment, our team was able to deliver a significant and immediate improvement in speed and stability, taking the pressure off the business while the larger redesign moved forward.

Once the new hardware arrived, our projects team executed a carefully planned infrastructure rollout — migrating workloads, reconfiguring the network topology, and validating performance at each stage. The result was a stable, efficient, and well-documented server environment built to support the firm’s operations for years to come.

The Outcome

The firm achieved immediate performance relief through our Tier 3 engineers’ environmental optimizations, eliminating the daily disruptions they had been experiencing. The subsequent full infrastructure redesign resolved every performance and stability issue they were facing, with the new environment delivering dramatically faster access to their tax software both locally and remotely. The firm now operates on a modern, right-sized infrastructure designed around their actual business needs.
