What is the name of the catalog from which bicycle shops order all of their supplies?

In the NW, many bike shops order from Seattle Bike Supply catalog. My guess is that there are other regional suppliers that cover specific areas. The prices are not available for the general public to see and you have to be a shop to get or order from their catalog.

Get a business license and you can buy from the wholesaler.

any kind of business license, or only a bike shop business license?

the place i was looking for actually was QBP (quality bike parts).
