Can I switch from an individual account to a business account?

I work as a dog walker/pet carer and have been selling treats/supplies on the side. I’d like to grow by starting to sell online and through amazon, but when setting up my account I saw I need to select business type. I think currently it makes more sense to register as a individual, but as I’d like to switch to a company in the future I was wondering if that would be possible with amazon? Also if you have any tips for while I’m starting out it’d be appreciated!
