Freelancing usually involves working for a production company owned by someone else on a job to job basis. If you shot two weddings on your own and what you termed a “interview shoot” and invoiced that client directly you are for all intents and purposes acting as a production company, albiet one with only one employee.
I work a day job in video and take on side projects under my company name. Obviously it’s a part-time situation where I do work in my “off-hours”, weekends, etc. but I do it under the banner of Mecca Video Productions. My documentaries are produced under that banner as well as my voice-over work. Just makes it easier. Business cards, car magnets, checking account, all carry the same banner.
As a sole proprietor there really isn’t much in the way of paperwork other than letters of agreement with clients and invoices. I keep track of expenditures, mileage, income and at the end of the year turn it all over to my accountant who takes care of my personal and business taxes.
