Ask HN: How do you track your billable working hours?

Spreadsheet?

I run a custom software development firm for fast-growing HealthTech companies. From 1 to 3 people, we utilized Excel. After 3 people we started utilizing Toggl Track as it was becoming a nightmare to record all our billable hours. Toggl has a feature-rich, free version up to 5 people that gives you a good idea if you like the platform. We're now a 14 person company on Toggl's paid plan (I think it's called team). Well worth the investment from my perspective. Eventually, I feel like we will outgrow Toggl, but I think it should scale to at least 25 or 30 people.

Same here. I've used Toggl and similar in the past but it was an overkill. Currently using 1 sheet per month setup, 1 row for day/task. Simple and works.

For all of the evils that spreadsheets cause, they are super easy to administer.
