Last month, Clark gave listeners early warning about Advanta. This ailing credit card provider to small business was dealing with an unprecedented amount of debt, and at the time had announced it would shut down all credit lines sometime in June.

But Advanta ran out of money early and shut down 1 million accounts on May 30. People who were traveling on business suddenly couldn't use their credit cards to check into hotels or rent a car.

So now the inevitable question: How can small business find access to funds in a post-Advanta world?

If you're a business with an open line of credit at a bank, draw down that money now before it gets cut off. Be sure to deposit the money at a different bank or credit union.

In most loan agreements, there's a clause that allows the bank to claw back the money owed on a loan when it is suddenly called due. So if the money is sitting on deposit at the issuing bank, they'll just help themselves to your account to get it. You could easily wind up bouncing checks all over town.

(Editor's note: This advice also applies to individual homeowners with a home equity line of credit.)

As a business, you need to have multiple lines of credit. But Clark knows that's easier said than done in today's climate. If your lines of credit being shut off would put you out of business, then you have some homework to do to line up alternate sources of funding.
