you might check out http://www.nolo.com this is a small publishing
press specializing in business and legal books in plain english. Also
you can probably go online to your state corporate/business division
and get answers to these and other related questions. For sales and
purchases what you would need I believe is a resale tax
- no sales tax here in Oregon so I don’t know if and EIN - which
is an Employer Identification Number - would serve the same purpose.
As an LLC you might need to have an EIN # for filing taxes, etc
since you are not a simple sole proprietorship ( in which case your
would basically be your social security #) This is not professional
advice - I’m a jeweler not an acct. or lawyer.
