How a Mississauga Accounting Firm Eliminated Downtime During Tax Season

Industry: Accounting & Financial Services | Location: Mississauga | Company: Sterling & Associates CPA | Size: 22 employees

95% Reduction in Downtime

The Challenge

Tax season was a nightmare. With 22 staff members relying on aging servers and an overloaded network, crashes happened at the worst possible times. The firm was losing billable hours to IT problems and risking missed filing deadlines.

• Aging on-premises server crashed 3 times during the previous tax season, each time taking 4-6 hours to restore
• Staff couldn't access client files remotely, limiting flexibility during peak periods
• No reliable backup system — a single hardware failure could have meant catastrophic data loss
• The part-time IT contractor took 24-48 hours to respond to urgent issues

The Solution

Group 4 Networks migrated the firm to a fully managed IT environment with 24/7 monitoring, cloud-based file access, and a dedicated support team that responds in under 15 minutes.

• Migrated all client data and accounting software to a secure cloud infrastructure with automatic failover
• Deployed Microsoft 365 for seamless remote collaboration and document sharing
• Implemented automated daily backups with 15-minute recovery point objectives
• Set up 24/7 proactive monitoring to catch and resolve issues before they cause downtime
• Provided dedicated help desk support with a 15-minute response SLA

The Results

• 95% less downtime — From 18+ hours of downtime per tax season to less than 1 hour total
• $2,000/month saved — Eliminated the cost of maintaining aging servers and the part-time contractor
• 15-min response time — Critical issues addressed in minutes instead of days
• 100% remote access — Staff can now work from home during peak periods, increasing billable hours by 20%
