When you say a "business debtor," if you mean an individual bankruptcy debtor with primarily business debts rather than primarily consumer debts, then yes, the pre-filing debt counseling course and subsequent financial management course are required. If the entity itself is being liquidated in a Chapter 7 bankruptcy, then no, the principal authorizing the bankruptcy is not required to file such a certificate as the entity is not an "individual" as defined by the Code. Keep in mind that even though the entity might liquidate in a Chapter 7 bankruptcy filing, if you are also personally liable, the bankruptcy for the entity will not provide you a discharge of the debts individually. In such cases, often times, the principal parties end up filing individual bankruptcy cases in addtion to the entity filing, and of course each individual would be required to take these classes.

You didn't say if your business is a corporation of some sort of a sole proprietorship. If the latter, there is only one entity, you (and presumably your spouse), to file the Chapter 7. If the business is a corporation and your business debts were personally guaranteed by you, then you'll probably need to do a personal bankruptcy to avoid those debts. Whether you also need to do a bankruptcy for the corporation is another question. Your corporation cannot get a discharge of its debt in a Chapter 7, and its assets would be liquidated to repay its creditors. Some people opt to simply wind down the business and avoid the cost of a corporate Chapter 7, while others want the "closure" it provides regarding future hassles from corporate creditors. If you should decide to do a corporate bankruptcy, make sure you file it prior to filing a personal Chapter 7 or else you will not have the authority to file the corporate Chapter 7 because the trustee in your personal Chapter 7 will have control of your corporation. Who said this stuff is simple... I strongly recommend that you consult with a qualified bankruptcy attorney in your area.
