You will be fine until you start to buy bulk amounts of items, until then you need to focus on making sure you don't get "burned" by your customers. Make sure you have you return and malfunction disclaimers set, and be on point with everything. I started a computer repair business and built/sold them in my spare time. Get a management program or app, something of the nature to make sure you don't forget doing anything. I used toggl until I got too dissatisfied, then moved to Freelancy.

if in USA , u need a library card to start learning about

"small business" concepts.

in Truth , u will simply be self employed untill

u actually make money.

having money coming in IS NOT making money.

a PROFIT is making money.

a library will allow u to learn b4 u get burned.

u in no way need to sign any thing.

use a library b4 spending dime or what ever currency.

But, do I need to sign any contracts or business stuff with the parts that I build the computers with?

A business plan and money.

Hello!

I want to start a computer building business. I want to buy parts from Amazon and Newegg, put the computers together, and sell it to make profit off them. Do I need to sign contracts, do government stuff maybe? I don't know what to do. Please tell me what I should do.

Many thanks!
