You started the dasa of Mercury (Lord of the 8th and 11th signs) from August 2020. Mercury sits in the 12th sign though he shifts to the 11th in Bhava chart. Mercury is nearly at 0 degrees and, consequently has not much strength. (Even on the date the dasa of Mercury started he was at 0 degrees in Leo and combust with a similarly placed Sun).
Even in Navamsa, Mercury occupies the 12th from both natal and Navamsa lagnas. Similarly in Dasamsa also, he occupies the same 12th sign from natal lagna. Mercury is also placed in the 8th house of the Drekkana chart (22nd Drekkana).
All these placements indicate that your Mercury dasa (17 years from 2020) will not be very profitable.
Regular prayers to Lord Vishnu, reciting/listening to Sri Vishnusahasranama daily with a prayer for help in business can aid your business.
