Comparing a Letter of Credit vs. Line of Credit for Business Owners

If you’re a business looking for financial backing, you may have heard the terms letter or credit and line of credit and wondered what the difference is between them. Although they have similar names, they do have unique purposes and structures respectively.

Both can be important tools that can help finance your business, and understanding the difference can help small business owners determine which one best supports their financial needs.

What Is a Letter of Credit?

Simply put, a letter of credit is a guarantee of payment for a transaction between two businesses. It is a document issued by a financial institution on behalf of the buyer, assuring the seller that they will receive payment under the agreed-upon terms. If the buyer fails to pay, the issuing bank covers the cost subject to the terms of the letter of credit.

Letters of credit are often used as negotiation tools in business transactions, providing assurance to both the buyer and the seller. For example, a seller might hesitate to ship goods without knowing they will get paid, and a buyer might worry about paying for something they haven’t received. A letter of credit provides peace of mind to both parties.

This tool can be helpful in international transactions, where differing laws, currencies, and business practices can make them more complex.

Types of Letters of Credit

There is more than one type of letter of credit available to businesses. Each one has a specific use, depending on the needs of the buyers and sellers. The types of letters of credit that are available are:

Standby Letter of Credit – The standby letter of credit provides for payment on behalf of the seller if the buyer defaults on the agreement.

Revolving Letter of Credit – A revolving letter of credit covers multiple transactions over a set time period, ideal for regular shipments between the same buyer and seller.

Confirmed Letter of Credit – Confirmed letters of credit involve two banks: the one issuing the letter and another, typically the seller’s bank, which is the confirming bank. The confirming bank is the one that ensures the payment on the letter of credit if the holder and the issuing bank default.

Commercial Letter of Credit – A commercial letter of credit provides the bank to make a direct payment to the beneficiary on behalf of the borrower.

What Is a Line of Credit?

A line of credit (LOC) works differently from a letter of credit. A LOC is a flexible loan agreement between a borrower and a financial institution in which the borrower is approved for a set amount of money they can draw from as needed. Interest accrues on funds that have been drawn and not yet repaid.

LOCs are often used to cover financial gaps, fund ongoing projects, or manage fluctuating expenses. They are especially helpful for small business owners looking for short-term financial support without the rigid terms of a traditional loan.

These accounts function similarly to credit cards: you can borrow up to your limit, repay the amount, and borrow again. However, unsecured lines of credit may carry higher interest rates.

The Differences Between a Letter of Credit vs Line of Credit

Letters of credit and lines of credit are two very different financial terms, each with different purposes and parties involved.

Final Considerations

While both letters of credit and lines of credit involve financial institutions and credit terms, their use cases differ significantly.

A letter of credit is best suited for businesses engaging in large or international transactions where trust and security are essential. On the other hand, a line of credit can help manage day-to-day operations, provide working capital, or offer backup funding for seasonal fluctuations.
