Tap your small business banker for a business line of credit

Banks that serve small biz offer commercial lines of credit. Biggies like Wells Fargo offer small business credit lines up to $100,000 that you can apply for online, even if you're not already a customer.

I recommend: Check the business line of credit line offerings at these banks active in serving small business: Wells Fargo, Bank of America, Washington Mutual, Wachovia, Key Bank. Or for strictly web-based banking, try NetBank.

Prepare the information you'll need to borrow money

To obtain a credit line, you may need to supply financial information about your business and/or yourself to potential lenders.

I recommend: The U.S. Small Business Administration has a good section on points to consider when borrowing money for your small business via loans or lines of credit. Pay special attention to credit history and questions a bank might ask. The Work.com Guide to Building a Business Credit Rating might also be of interest.

Look to non-banks like UPS and American Express

UPS - a big name in small biz shipping - is also a major small business lender under its UPS Capital wing, offering loans and lines of credit. And the American Express "Open for Business" program offers business lines of credit.

I recommend: Check the case histories of how UPS Capital is helping small businesses grow and see the various small business loan solutions that are offered. The business line of credit from American Express ranges from $10,000 to $100,000 with no collateral needed. There's an easy online application and the APR is as low as prime plus 2%.

Comparison shop multiple sources

Sources of small business credit lines are numerous. To find the perfect fit and absolute best terms, you can comparison shop among many lenders.

I recommend: Enter your information at BusinessFinance or iBank – both are web portals that match lenders with small businesses, to find the best fit for your particular needs.

The U.S. Small Business Administration (SBA) helps small businesses meet short-term and working capital needs through its CAPLines program. Choose from five types of credit lines, including seasonal, contract-based, builder's line, asset-based and small line.
