In some companies, employees can decide for themselves when they work on a project. Sadly, the result is that the hours spent quickly do not match the planned hours.
We use a spreadsheet input as best practice. Simply move around with your cursor keys and type in the hours. To make it even easier, you can copy your planning booking and only make changes where needed. It doesn’t get easier than this.
Optionally, you can add a description and report progress. You can manage your favourite projects which makes input even faster. A simple colour system will indicate the status of your time sheets (e.g. submitted, approved, rejected).
