Tracking Billable Hours: Best Practices for Accountants

Published 29 September 2026

Most UK accountancy firms haemorrhage money in the same way: untracked billable hours. This isn't a software problem; it's a process one. The partner finishes a client call, scribbles notes on a post-it, and forgets to log the time. By month-end, 15% of the billable hours vanish into thin air. It's not just inefficient; it's a revenue killer.

The Cost of Manual Time Tracking

Manual time tracking costs accountancy firms up to 15% of billable hours, according to industry estimates. For a small firm billing £250,000 annually, that's a potential loss of £37,500. The problem stems from reliance on outdated methods like spreadsheets or, worse, mental notes. These methods are error-prone and time-consuming, leading to missed entries and unbilled work. The solution is straightforward: automation. By using practice management software like ilmove Accountancy, firms can automate time capture, ensuring every minute worked gets billed. This software tracks time seamlessly, integrating directly with client and project data, reducing administrative overhead and increasing billing accuracy.

Best Practices for Tracking Billable Hours

A few key practices can drastically improve how you track billable hours. First, implement real-time tracking. Encourage staff to log hours as they work, using mobile apps or desktop software. This immediate capture reduces forgetfulness and ensures accuracy. Second, set regular reminders. Automated notifications from tools like ilmove Accountancy can prompt timely entries, reducing the end-of-month scramble. Third, review and analyse time data weekly. This proactive approach allows firms to identify patterns, adjust workloads, and improve profitability.

In our experience, the firms that excel at time tracking do so by making it part of their culture. They don't just rely on technology but back it up with regular training and clear expectations. This combination of tech and human discipline creates an environment where every billable minute is captured and valued.

Automating Time Tracking: The Role of ilmove Accountancy

ilmove Accountancy automates time tracking by capturing hours directly from client engagements and project work. This integration eliminates the manual entry errors that plague traditional methods. For instance, when a partner finishes a client consultation, the software logs the time automatically, ensuring nothing slips through the cracks. The result? Firms see a significant reduction in lost hours, often cutting the 15% revenue leakage in half or more.

Another feature is the intuitive dashboard that provides real-time visibility into billable hours across the firm. Managers can quickly see who is working on what and adjust resources accordingly. This transparency not only boosts productivity but also enhances client trust as billing becomes more consistent and justifiable.
