Have used Quicko services for filing ITR 3 with audit report for AY 19-20. It has been a delight to have availed of their services.
I have income from salaries, other sources, other business besides trading and all were duly considered in this filing. All documents were submitted conveniently online by myself and were used bu Quicko team to prepare ITR and all detailed supporting.
Will highly recommend to go with them for all filing with minimum hassle.
