Building business credit can be daunting if you are unfamiliar with the process. The absolutely first thing you'll have to do is have a business. A corporation or LLC should be fine to start building business credit. The state where you incorporate is not very important for the business credit side of things.
Once your business is setup you will need to make sure it is listed in 411. When you submit applications for credit many companies will search for your business in a 411 listing to verify the phone number on your application.
Business credit bureaus collect information and report it to businesses that subscribe to their service. There are 3 major business credit bureaus: Experian, Equifax, and Dun & Bradstreet. Some creditors report to Experian only, some report to D&B only, but the ones that help you the most will report to Equifax, Experian, AND D&B, giving you a tradelines on all the major business credit bureaus.
Net 30 accounts mean you have 30 days to pay the invoice after purchase. A few of the net30 credit companies might require you to place 1-2 orders where you pay-in-full upfront before they will give you net30 billing. Net30 creditors include phone companies, gas cards, and office supply stores.
Your business will need 4-5 tradelines reporting in your credit file to start applying for the next level of non-PG credit retail revolving credit accounts. Wait a month or two after paying before you can expect the net30s to report. Even if you get in on net30 terms pay before the due date. This will be a positive factor for your business.
Some net30 accounts are easier than others but once you get that first one reporting things should fall in line. If you need business cell phones this can be an easy way of getting net30 tradelines reporting. The higher the balance of your net30 order the better. When ordering you can ask if there a minimum dollar amount before they will report to credit bureaus. Your high balance is usually reported and creditors like to see high paid balances if they are going to offer you a high credit limit.
Now you need to spend some time building business credit and get those net30 accounts reporting. It may take a few months to get but once that happens a lot of the hard work is over.
