After running a business in Denver for a few years, there comes a moment when banks or credit card companies start to recognize me.

When I first started my business, even getting a credit card required a lot of scrutiny, but after consistently paying my bills for over five years, the atmosphere changes one day.

"We can lend you up to $9,000 as needed."

A letter like this arrives from Amex, and my primary American bank offers to open a $10,000 line of credit.

'Finally, even in Denver, an American financial institution is properly recognizing me.'

Combined, that's $19,000.

With just a few taps on an app, I can access it whenever I need, making it feel like my emergency fund.

But I need to stay alert here.

A line of credit in the U.S. isn't inherently bad.

In fact, it's a very useful financial tool for small business owners with fluctuating monthly revenues, serving as a reliable emergency cash reserve.

For example, let's say a client delays a $10,000 payment by a month.

But employee salaries, rent, and material costs won't wait for me.

In this case, I can temporarily withdraw $5,000 from the line of credit to put out the fire, and once the client's payment comes in, I can pay it back immediately. This is the proper way to utilize it.

The problem arises when I start to mistake this credit limit for 'my money.'

If I rely on the $9,000 from Amex and feel secure with the $10,000 from the bank, it can quickly lead to debts exceeding $20,000 or $30,000 when combined with credit card balances.

Especially for businesses in Denver that are seasonal during winter, a moment of complacency can lead to getting stuck in a swamp.

Ultimately, what's important is not 'how much can I borrow?' but 'why am I borrowing and how will I repay it?'

If I can pull in $10,000 to generate an additional $20,000 in revenue for business expansion, that's a meaningful investment.

On the other hand, if I'm constantly running a deficit and relying on credit to cover rent and living expenses, that's a serious warning sign. It means I'm starting a vicious cycle of borrowing to pay off debt.

I see a line of credit as a fire extinguisher.

Just like you shouldn't start fires every day with a fire extinguisher at home.

Even if I've been approved for $19,000, it's just an emergency exit I can open when needed.

If I can hold off on using it, that's the most comfortable situation, and if I use it briefly and pay it back at lightning speed, it becomes the best tool.

In fact, having this credit line set up when business is good and sales are high is a piece of American business wisdom.

When real money runs dry, if you go to the bank then, they will never lend you money.

If Amex offers $9,000 and the bank offers $10,000, be grateful and accept the approval. Just remember one thing.

In the U.S., having good credit doesn't mean 'you can borrow a lot of money,' but rather 'even if you have the ability to borrow, you don't have to if you don't need it.'
