While dropshippers charge generally a higher price for products, getting the required documents really isn't that difficult. Most distributors only want to see that you are truly in business to produce a profit, & if you live in the US, so does the IRS. But, again, that isn't really hard.

or by calling the IRS at (800) 829-1040.
Next, get a Resellers' Permit, which gives you authorization to sale in your state. For California residents it would be through the Board of Equalization. Some cities require business licenses, but if selling strictly online, it's not always required, depending on the vicinity. These are required in order to set up & buy directly from most distributors.
