It is very simple and useful to have your company details correct so that you can take full use of features that use this information; such as invoicing, work reports and more. Adding company details is very easy. You navigate to Administration and then to Settings.
On that page you will find an area named Company details where you can click the edit button and enter your information in this modal window.
You can even upload your logo that is used on work reports. Be sure to use a logo that assumes a white background because work reports, invoices and more have white backgrounds.
Once everything has been entered - just press Save and you are done!
