When you are deciding whether or not your company needs a business line of credit, the first thing you should determine is how much your business can safely borrow. In order to do this, you should review your cash flow analysis to see the amount of principal that can be repaid on an ongoing basis if it is required by your lending institution. In some cases, a principal repayment does not need to be made on a monthly basis as it relates to your business line of credit. Instead, at the end of the credit facility, the outstanding principal balance is converted into a loan and regular payments of interest are made. However, this methodology is becoming somewhat antiquated as banks are taking fewer risks when it comes to the extension of credit. Now, you will most likely be required to immediately repay any outstanding balance once the term of the credit line is complete.
