Slack Time Tracking vs Dedicated Tools for Small Teams

Why small teams even consider Slack for time tracking

Teams of three to eight people often already live in Slack. They ask whether they can simply track hours there too. It sounds efficient at first. One less tool, one more channel.

I tried this myself when Jomawo was still four people. A bot was supposed to collect the times. After two weeks it was obvious: the data was incomplete and reporting took too much effort.

How time tracking works inside Slack

There are two common approaches. Either everyone posts their hours in a channel or a bot asks via slash command or reminder. Some teams use threads per project.

The advantage is obvious: everyone is already there. No one has to open another app. But that is exactly where the problem starts. Messages get lost quickly in the feed. Later, finding last week’s entries for project X means a lot of scrolling.

Common pitfalls with Slack time tracking

A frequent issue is forgotten entries. The next day the memory is already vague. Or two people log the same task because the thread was not clearly assigned. I saw this multiple times in our own team before we switched.

Another topic is breaks and absences. Slack does not notice automatically when someone goes offline. You have to track manually that someone only worked four hours instead of eight.

What dedicated tools do differently

A proper time tracking tool starts and stops time with one click. It separates projects cleanly and shows at a glance how many hours have already been used. For small teams the monthly overview matters most.

I remember a founder who said: “We used Slack for three months and then needed two days to pull the data together for invoicing.” After that he moved to a dedicated tool.

Concrete calculation example

Take a team of five. Each person loses or forgets on average 12 quarter hours per month through Slack. At 85 euros per hour that equals 51 euros lost revenue per person. For the whole team that is 255 euros per month. Over a year this adds up to more than 3000 euros. This is only the direct revenue loss – the extra time spent on manual reconciliation comes on top.

Practical comparison

The table makes the differences clear. Slack wins on entry barrier. On everything that matters at month end, a dedicated tool is ahead.

When Slack is still enough

For pure internal coordination without client invoicing or legal documentation, Slack can work. If no one needs to prove hours externally and everyone logs entries consistently, the extra software is unnecessary.

With our users I usually see the opposite: as soon as a team issues even one invoice or needs to track overtime, the effort with Slack quickly exceeds the benefit.

What small teams actually need

Most teams under ten people mainly need two things: fast start and stop of time plus a clean export at month end. Both come built-in with a dedicated app.

Another often underestimated point is team adoption. If the tool feels complicated, it will not be used. That is why we at Jomawo focus on as few clicks as possible. Feedback from small teams has been very clear on this.

If you are still unsure, you can start with the free time tracking at jomawo.com/en and decide after two weeks whether the data is better than what you had in Slack.
