A business credit card is built for small, frequent purchases you can pay off quickly. A business line of credit is built for larger, planned or unexpected costs that take longer to repay, usually at a lower interest rate. Most owners end up needing both, and the real question is which one should carry which expense.
This guide compares the two on the points that affect your cash flow: cost, limits, approval, interest timing, credit impact and typical uses. It finishes with a decision framework and a worked example with numbers.
TL;DR
- Use a business credit card for routine, smaller expenses you can clear within the billing cycle, such as software, fuel, supplies and travel. Cards often come with a grace period and rewards.
- Use a business line of credit for bigger needs: inventory, payroll gaps, seasonal shortfalls and repairs. Rates are frequently lower than card APRs on balances you carry.
- Cards are easier to get, often with approval online in minutes. Lines of credit usually involve underwriting and a longer operating history.
- Interest on a line of credit generally starts the day you draw. Many cards give you interest-free days if you pay in full.
- Plan ahead. Apply for a line of credit while your finances are healthy, not in the middle of a cash crunch.

How the two products actually work
Both are revolving credit. You get a limit, you borrow part of it, you repay, and the available amount comes back. The differences are in how you spend the money and how the lender prices it.
Business credit card
A business credit card is revolving credit issued under the business's name. You pay vendors by swiping, tapping or entering the card number online. You receive a statement each month, owe at least a minimum payment, and pay interest only on whatever balance you carry past the due date.
Cards are good at what the SBA describes: they can help keep personal and business expenses separate and build your business credit file. Many also offer rewards, employee cards and expense reports that your bookkeeper will appreciate.
The weak spots are the limit and the price of carrying a balance. Card limits tend to be modest compared with the size of a major business expense, and the APR on an unpaid balance is high.
Business line of credit
A business line of credit gives you a maximum amount you can draw from when you need it. You usually request a draw and the funds land in your business bank account. You then pay interest on the amount drawn, not on the full limit, and repay according to the lender's schedule. Once you repay, the credit becomes available again.
Because the money arrives in your bank account, you can use it for things a card cannot pay for: a supplier who does not take cards, a payroll run, a deposit on a job, or a tax payment. That flexibility is the main reason owners keep a line open even when they rarely draw from it. For a deeper look at how draws and repayment work, see our guide to what a business line of credit is.
Line of credit vs. credit card at a glance
| Feature | Business line of credit | Business credit card |
|---|---|---|
| Best for | Larger, planned or unexpected costs; cash flow gaps | Everyday, smaller purchases and travel |
| How you access funds | Draw to your bank account | Pay merchants directly |
| Typical interest cost on a carried balance | Often lower | Often higher; card APRs commonly run 14% to 29% |
| Interest timing | Usually starts at the draw | Many cards offer a grace period if paid in full |
| Rewards | Rarely | Common |
| Approval | Underwriting; track record and financials reviewed | Often quick, sometimes within minutes online |
| Fit for newer businesses | Harder | Easier |
| Works for vendors that do not accept cards | Yes | No |
Treat the table as a general pattern. Individual lenders and issuers differ, and your own credit profile drives the final terms.
Cost: where the real difference shows up
Cost depends on two things: how long you carry a balance and what rate you pay.
Interest rates
The FDIC's small business financing material notes that business credit cards typically carry higher interest rates than term loans. Lines of credit, whether secured or unsecured, frequently price lower, although the range is wide and depends on market conditions, creditworthiness and collateral.
That gap matters only if you carry a balance. If you pay your card in full every month, you may pay no interest at all. If you carry the balance for months, the card is usually the more expensive product.
Grace periods and when interest starts
Many business cards let you avoid interest entirely if you pay the statement balance in full by the due date. A line of credit generally works differently: interest starts accruing when you draw. So a card can be the cheaper way to borrow for three weeks, and the line the cheaper way to borrow for three months.
Fees to read before you sign
With either product, look past the rate:
- Annual fees on cards, especially those with rewards.
- Draw fees, origination fees or maintenance fees on lines of credit.
- Cash advance fees on cards, which are usually costly and start accruing interest right away. Using a card cash advance to cover a large vendor payment is a mistake the SBA specifically warns owners about, because a line of credit exists for that situation.
- Late and over-limit fees on both.
Our breakdown of what small businesses pay for a line of credit walks through how rates and fees are typically structured.
A worked example: the same $25,000, two ways
The numbers below are an illustration, not a quote. They use round assumptions so you can see how the math behaves.
Imagine a plumbing contractor who needs $25,000 to buy materials for a job and expects to be paid in 90 days.
On a credit card at an assumed 24% APR (2% per month): if the card has a $25,000 available limit and the balance is carried for three months, interest is roughly $500 per month, about $1,500 over the period, before any fees. A card with a 21-day grace period would not help here, because the balance will not be paid by the due date.
On a line of credit at a rate of 1.2% per month: that is the starting rate we list for our business line of credit. Interest on a $25,000 draw would be about $300 per month, or roughly $900 over three months, plus any fees on the facility. Your actual rate depends on your credit profile and business history.
The difference in that scenario is about $600. Change the facts and the answer changes too: if the contractor expects to pay in full within 15 days, the card with a grace period could cost nothing.
The rule of thumb: the longer you need the money, the more the lower rate on a line of credit matters. The shorter the time, the more the card's grace period and rewards matter.
For another illustration of how interest-only draws look in practice, see our example of a $25,000 draw with interest-only payments.
Limits and how much you can borrow
Card limits are usually set from your credit profile and business revenue, and they tend to be smaller than line of credit limits. A card may be fine for $5,000 of monthly operating expenses. It is a poor fit for a $60,000 inventory order.
A line of credit is designed for larger amounts. Our own business line of credit is available up to $250,000. Depending on the lender, the limit is a function of revenue, time in business and credit, and can be increased later as your business grows.
One point that often gets overlooked: a high card balance can use up much of your available credit and may hurt your credit profile, while a line of credit that you draw sparingly generally leaves you with a cushion you can access quickly.
Approval: who qualifies for which
Credit cards are easier to get
Business credit cards are commonly available to startups and newer businesses, and the SBA lists them among fast and popular funding options for a new company. Approval can come within minutes online, as the FDIC notes.
Lines of credit ask for more
A traditional line of credit typically requires a more established track record, often a minimum of two years in business and healthy annual revenue. Underwriting may include a review of financial statements. The SBA also says that, to qualify for a line of credit, traditional banks typically require a fairly strong profile.
That is why timing matters. If you wait until payroll is due and cash is tight, you have the least leverage. Apply when your revenue looks good and your bank balances are healthy, and you will see better terms and fewer surprises.
If a bank has turned you down
Banks are not the only source of lines of credit. Online and alternative lenders often work with a wider range of credit profiles, usually at a higher rate than a bank would charge a strong applicant. If you have been declined elsewhere, a lender like us can review your situation. We cover how unsecured lines of credit work, including the trade-offs, so you know what you are agreeing to.
Credit impact: personal and business
Both products can affect your credit, but in different ways.
- Utilization. Revolving balances relative to limits can influence scores. Keeping a card balance low relative to its limit is generally better than running it near the maximum.
- Personal guarantees. Small business cards and many small business lines of credit commonly require a personal guarantee, which means your personal finances can be on the hook if the business cannot pay. Read the agreement for this before you sign.
- Reporting. Whether the account reports to personal credit bureaus, business credit bureaus or both varies by issuer and lender. Ask before you apply.
- Building business credit. A card used responsibly can help build your business credit file, and a line of credit repaid on time can strengthen your profile for larger financing later.

The risk with cards: revolving balances
The SBA's guidance reminds owners that cards and lines of credit are distinct tools, not substitutes. The risk with a card is how easily a small balance becomes a large one. The Consumer Financial Protection Bureau's credit card market report shows how heavily issuers earn from interest and fees on balances that are carried. That report covers consumer cards, but the arithmetic of revolving interest is the same on a business card.
A line of credit carries its own risks. Drawing the full limit for a long time can strain cash flow. Variable rates can rise. And because the money lands in your bank account with no friction, it is easy to use it for spending that does not produce revenue. A line of credit works best with a plan for what each draw will pay for and when it will be repaid.
Typical uses for each
Put these on a business credit card
- Software subscriptions and online advertising
- Fuel, tolls and vehicle expenses
- Office and shop supplies
- Business travel and meals
- Small tools and consumables you will reimburse within the month
- Employee expenses where you want spending controls
Put these on a business line of credit
- Inventory purchases ahead of a busy season
- Covering payroll while you wait for customer invoices
- Materials and subcontractor deposits on larger jobs
- Emergency repairs, such as a failed HVAC compressor at a restaurant or a broken delivery van
- Vendors that will not accept cards or that add a surcharge
- Short-term bridging between large receivables
The SBA describes the split in similar terms: cards for routine, smaller expenses, a line of credit for larger or recurring needs like inventory, cyclical shortfalls and unexpected repairs.
When neither is the right tool
Some needs do not fit a revolving product. Buying a large piece of machinery is often better handled with equipment financing, where the equipment itself secures the loan and the payments run over a fixed term. A one-time expansion may suit a term loan. If you are weighing a line of credit against a loan, our guide on four key questions to ask helps you decide.
How to choose: a five-question check
- How long will I carry the balance? Under a month, a card with a grace period may cost you nothing. Over a few months, a line of credit is usually cheaper.
- How large is the expense? Small and frequent points to a card. Large and lumpy points to a line of credit.
- Does the payee take cards? If not, a line of credit that deposits to your bank account is the practical choice.
- How long have I been in business? A newer business may qualify for a card first and a line of credit later.
- Do I want rewards or flexibility? Rewards help on predictable spending. A line of credit gives you a reserve for the unpredictable.
Using both together
Many owners run both on purpose. The card handles day-to-day spending and earns rewards. The line of credit sits behind it as a reserve. If a big expense arrives, you draw on the line instead of putting it on the card. If a card balance gets out of hand, you can pay it down with a draw on the line at a lower rate, provided the line's terms allow that use and the cost of the draw is lower than the card's interest.
Our perspective: plan the line before you need it
We have worked with business owners in hundreds of industries since 2009, from contractors and electricians to restaurants, florists and retailers. Across those industries we see the same pattern. Owners reach for the card because it is in their wallet, and it works until a larger cost shows up. At that point the card's limit is too small or its interest is too high, and the owner is applying for financing under pressure.
Our view is simple. Use a card for what a card is good at. Set up a line of credit while the business looks strong, so that the reserve exists when a slow month, a late-paying customer or a surprise repair arrives. Draw only what you need, and know in advance how you will repay it.
If you have been told no by a bank or credit union, that is not the end of the conversation. We work with a broad range of credit profiles, and we can often move quickly, in some cases funding as soon as 24 hours after approval. Pricing will reflect your profile, so compare the total cost, not only the speed.

Mistakes to avoid
- Using a card cash advance for a large payment. The fees and interest are generally much higher than a line of credit.
- Waiting until you are in trouble to apply. Underwriting takes time, and a strong application is easier to put together before a crisis.
- Drawing the whole line because it is there. Interest is charged on what you draw, so keep draws tied to a specific purpose.
- Mixing personal and business spending. Separate accounts and cards make tax time and lender reviews far simpler.
- Ignoring the fine print. Check for personal guarantees, fees, variable rates and how repayment is structured.
FAQ
Is a line of credit or a credit card better for a small business?
Neither is better in every case. A card suits small, frequent purchases you can pay off quickly, and it can earn rewards. A line of credit suits larger or less predictable costs and generally has a lower rate on balances you carry for months.
What are the disadvantages of a business line of credit?
It typically requires a longer operating history and more documentation than a card. Interest usually starts accruing at the draw, with no grace period. Some lines carry fees or variable rates, and many require a personal guarantee.
Does a business line of credit affect my credit score?
It can. The lender may run a credit check at application, and how you use and repay the line may be reported to credit bureaus, depending on the lender. Drawing a large share of the limit can raise your utilization, while on-time repayment can help your profile. Ask the lender what it reports before you apply.
Can a new business get a line of credit?
It is harder. The SBA notes that traditional lines of credit typically ask for a track record, often two years in business. A newer company may start with a business credit card and look at other financing options in the meantime, such as loans designed for startups.
