Taxumo has a feature that allows you to upload your income or expenses in bulk.
To use, it simply press on the button that looks like three vertical dots:
Download the Template which is in CSV Format.
Fill it out using your favorite spreadsheet editor and save it back to CSV format. Do take note that you have to make sure that the categories you used are correct AND that the formatting of the dates are correct.
Press on the three vertical dots again and press Upload Income or Upload Expense.
If there are any errors, the errors will be displayed, otherwise, the upload was a success. :)
