You pay interest to yourself instead of to a bank, and you need not give up any stake in your company to investors. Avoid withdrawing retirement funds unless you are under 35 and have ample time to rebuild your savings should your business fail. At a minimum, this agreement should include the amount you will be borrowing, the interest rate and the terms of repayment. Promise a fair rate of interest on the loan. Be sure to agree on a payment schedule that you can keep without putting a strain on your business.
Credit cards provide another ready, though expensive, source of cash.
Shopping for a low-rate card may cut your interest costs. Insure yourself and your business. Write contracts with clients. Collecting cash is one of the biggest hassles of managing your own business. To make things easier, put every agreement in writing.
