I had a request from client today. they wanted to see detailed YTD payslip items for an employee. I had to do it manually because Kashflow only shows totals in Payslip by Items Report. Therefore, this is something to be improved in Kashflow I think.
Have you tried using the Payslip Crosstab report? This will give you a much more detailed report per employee and will also allow you to export to CSV to make additional changes if you require.
