You can send generated files to your accountant. You can generate the files using the information from the mobile application and then you can select an application installed on your device (e.g. gmail) or you generate the files on laptop/PC via the website application and then the file will be saved on your computer and you can send it via email.
If you would like to track the trends in your business - we recommend you use reports which you can easily create using My Invoices or My Expenses. Enter My Invoices or My Expenses, click the "Filters" section, upper right corner and click on the "Report" tab. These reports are more complex and you can use them to make calculations and charts.
