Cannabis Accountant
At Price Kong, our goal is to provide the highest quality and most valuable service to this emerging industry.
Soon after Arizona’s medical cannabis law was made effective in 2011, Price Kong began providing audit, tax, and consulting services to businesses awarded a license, and the subsequent approvals to operate. No other accounting firm in Arizona has served cannabis businesses longer than Price Kong.
What Sets Us Apart in this Industry?
Experience and commitment to the industry! Since 2011, Price Kong has led the efforts of Arizona accounting firms and Arizona CPAs servicing this new and growing industry. Our professionals have spent 1,000s of hours collectively researching and studying this industry, and the complexities inherent to it. We have proprietary models, strategies, and processes that we have implemented at dozens of cannabis businesses that save them time and money.
It’s extremely important to keep current on industry-specific laws and regulations and network with lawyers dedicated to serving this industry. Price Kong has an exceptional network of professionals dedicated to serving cannabis businesses.
We currently serve cannabis clients in Arizona, California, Nevada, Oregon, Washington, Colorado, Ohio, Pennsylvania, Maryland, Massachusetts, and Arkansas.
