Because we know what contract a freelancer is working on, our timesheets are simpler than most alternatives. All you need to do is fill in the time you spent on each day during the booking. Blank timesheet entries (one per day) are generated each day, so you cannot fill out time in the future - only on the day in question, and the past.
You can fill in your timesheets with half or full days.
At the end of each week (or the end of the project, if that happens mid-week), you should submit your timesheet for approval. Once you've submitted your timesheet for approval, you can upload your invoice immediately via the 'invoices' tab. If you're using an umbrella company then please view this article here on how to invoice.
