Time tracking? Why would I even care? If you’re a developer, you’re most probably paid by the hour (if not, then well, you’re the luckiest bunch), or if you’re working as a tech lead for a team of developers, then you’ll need to use some sort of system to check your freelancers or remote employees’ progress or time spent on any given project. There’s a chance you have a spare budget or willingness to spend a dime on a proprietary time tracking system like Hubspot (the one we use at Soshace), but if you’re on a limited budget, open-source time tracking tools can be a real-life savior. Herein, we’ll cover the best time tracking software that’s open-sourced and available for free. If there’s something we’ve missed, please comment below!

Manual vs automated time tracking software

Perhaps, you’re most familiar with tracking your time manually in Excel spreadsheets or any other more or less tangible attendance registry. The problem with this approach is that you basically give out the responsibility of filling out the timesheets to your employees, completely trusting them in their honesty and loyalty to your business. And while most of the employees are, indeed, virtuous and honest human beings, there will always be someone on the lookout to easily benefit from you. Besides, let’s be honest, manual time tracking doesn’t provide the slightest bit of high-level accuracy, it’s time-consuming, and it’s most often than not hardly verifiable. Conversely, the time tracking tools eliminate the issues with inaccuracies and things like “oh, I forgot to write it down.” Moreover, time tracking software gives managers a detailed analysis of different sets of data: the time spent by an individual or a team on a project, the efficiency of an employee/team, etc.

How does time tracking work?

Time tracking functionality is usually pretty flexible and customizable and therefore differs depending on the needs of your company, types of projects, and further intricacies of your business. But basically, all of them allow you to add/delete projects, create tasks within those projects, assign team members to particular tasks and projects, start/stop the timer, track time, produce reports. Some of the tracking systems can be integrated with other software like payroll, accounting, project management, and others.

Benefits of using time tracking software

The most common benefits associated with using time tracking software are

  • Opportunity to eliminate human errors, fallacy, exaggeration, etc., gain accuracy in attendance and performance.
  • Easily track hours spent and use that knowledge to improve productivity
  • Automate timesheet calculation and save human hours and money associated with those costs
  • Monitor performance, set up weekly limits or deadlines
  • Review data, analyze reporting for payroll or client billing
  • Getter better insights into works performed
  • Execute a transparent work process
