The process to doing business with San Bernardino County begins with registering with the online procurement system (ePro). You can register at epro.sbcounty.Register Your New Business Online. The City of San Bernardino Business Registration Division now accepts new applications via web registration. For more information about registering in electronic procurement, please refer to "New Vendor. Registration" on page 5. Your name is your brand so it must reflect all the aspects of your business plan. The "Starting a New Business in California" brochure should be used as a general tool to help you broadly assess how to start a business in California. All vendors must register with OpenGov Procurement (formerly ProcureNow) in order to receive bid solicitations. Fill out a Business License Application (link here to form) and contact the Business Tax License Section of the Records Department at (760) 255-5123.
