Where are my fellow 1099 reps?

Hello my fellow War Roomers!

So I am starting a SDR role next week as a 1099 employee with plans to be brought onboard as a direct employee after 3 to 6 months. Has anyone here ever worked in a role like this or currently works as a 1099 employee? Do you have any advice for someone that has never worked in a space like this? Questions I should be asking my future employer? Apps or websites that help with tax purposes/planning?

Any and all advice is greatly appreciated!
