in one payment ?!? I am in trucking business for 3 years. I was doing well until last year.I was living from check to check to make this business work.This year it is much wors. I used company credit cards. I am like 50 000 in debt and there is no more chance I can make those money in this business. I was thinking about take all those credit card and make that on loan and make payment, but I am not sure I will be able to pay that and those companies ofering this loans there is for sure some hiden fees and lot more.....I also thought about business bankcruptcy. I am only owner of trucking corporation. And If I file for bancruptcy will that damage my personal credit ?!

First of all, filing for bankruptcy costs anywhere from $10k to $100k (depending on the type of BK you file). Secondly, all of those "business" credit cards you used are personally guaranteed by you. If you see no chance in you making any more money in this business, how do you plan to get a loan? Loans for small businesses are personally guaranteed by the owners of the business. Your best bet is to talk to your accountant to see if selling your assets can offset some or all of your debt. You can also talk to an attorney to see if he can negotiate a deal with the credit card company (some companies/law firms specialize in this).

Bankruptcy should be your absolute last resort so put that on the bottom of the pile.
As a business owner, you have options that can help out. First, try calling up all of your creditors and negotiate a payment plan. They really would prefer to get their money over a longer period of time than not at all. Also, if you can afford it, go over your books and see where you can cut cost and maybe sell off some equipment that you don't really need. Maybe consider changing your marketing strategy to get more clients.This might mean that you have to add a partner or employee.
If you have a home, you may consider getting a home equity loan to help out on some of the bills and you may be able to refinance your truck payments as well. Also, check out some trucking associations, many have financial counseling and free advice. Good luck.
