California has the secretary of state and the board of equalization and also
many other venues. I would suggest looking online your state portal and also
contacting a local sba office. They usually have pamphlets that will break
down the requirements, rules and regulations.

We are in the wholesale business too as an online retailer of power tools. Take a look around our site for an example of a wholesale e-commerce business model.

Please help me. I am trying to get more information about companies that can help me apply for wholesaler permit in all states. Are there any? Or I should apply myself in each state individually?

Thanks for the great advice BuzzGuy and TR_OK! Thanks for joining the community! We're glad you're here. Have you tried the license and permit tool on Business.gov? Here is a link to it: http://www.business.gov/register/licenses-and-permits/. Just type in your state or city and it will return links on what permits are required. Best of Luck, JenniferD

RT @wolfspiritp : First of all, there is no Licensing required for wholesale operations. There is also no such thing as an Importers license.What you will need though is a licensed Customs Broker to clear your shipments through Customs when they arrive from over seas.To legally operate your business, you will need and Resale Tax License from your state Department of Revenue. This is a simple form, but normally requires a cash deposit based on what the potential sales tax revenues would be over a 3 month period. You are then required to submit sales taxes to the State, normally on a quarterly basis.Remember, though, Sales to out of state locations are non taxable, so the majority of your sales would not involve sales tax.Your local city or County may also require a Business license. This can normally be acquired through your local city hall or County Seat.Good luck with your new venture. Source(s): Import/Export for the past 10 years

If all else fails, contact your local Small Business Development Center- I'm sure they've answered this question hundreds of times. http://sbdc.mt.gov/offices.asp They will be a great resource for other questions as well.

http://mt.gov/services/business.asp If you can't find it there you'll need to contact your local state office in your area and simply ask them and they will tell you; I believe this is done with the Montana Revenue Service.
