Greetings to all. I thought I'd add to this post as well. I've had an LLC open for about 2 years as of this Febuary. Recently i started to work on my biz credit profile and finding some success. Net 30 vendors i have currently are...ULINE, QUILL, GRAINGER, SUMMA, AND MONOPOLIZE YOUR MARKETPLACE. Will start to apply to revolving credit after 30 days of reporting. From what I've read, you need 10 tradelines, with at least one tradeline (revolving credit account) with a $10,000 credit limit to be considerd for a business credit card.
