Underwriting is the process through which a lender determines if your business is creditworthy and should receive the applied for loan. All businesses need capital of some sort to get started, and being able to pass underwriting to receive financing in the form of a business loan is a key step to the success of your business.
The best thing you can do for your business to make sure you can pass underwriting is to get your business credit scores established and in place. Without business credit scores you will more than likely be declined for the commercial loan, and you would be forced to personally guarantee the loan. This is because going after a business loan without business credit scores is the equivalent of attempting to purchase a house or a car with no personal credit history.
