"JJ Gold" appears to be a business that offers a Net 30 account. This is a credit arrangement that provides businesses with benefits such as improved cash flow and enhanced vendor relationships. They report to two major business credit bureaus, Dun & Bradstreet and Experian Business, which can help businesses build their credit. However, they only offer Net 30 payment terms on 50% of purchases and have a $99 annual fee. It's important to note that while this information suggests that "JJ Gold" is a legitimate business, it's always a good idea to conduct further research or consult with a financial advisor before making any business decisions.
