A business credit card is one of the more useful things a small company can hold. You earn rewards on spending you were doing anyway, bookkeeping gets cleaner because business expenses stop mixing with personal ones, and you get roughly a month of free float between buying something and paying the statement. For software, fuel, travel and supplier invoices in the hundreds or low thousands, very little beats it.
The problems appear at the edges. Limits on small business cards commonly land somewhere between $5,000 and $50,000, and issuers often size them against the owner’s personal credit as much as the company’s revenue. Try to put a $60,000 machine on one and it declines. Carry a balance for a few months and the interest quietly swallows whatever the points were worth. That is usually the moment owners start looking at a line of credit, either from their bank or from a lender such as BusinessCapital.com, because the purchase has outgrown what a card was built to do.
Three places the card runs out
The ceiling. Card limits are set for operating expenses, not capital purchases. A single delivery van, a commercial oven, a bulk inventory buy ahead of the holidays: any one of these can exceed the entire limit. Even when the purchase fits, dropping $30,000 onto a $40,000 card pushes utilization to 75% and can drag down the personal credit file the card is tied to.
The cost of carrying a balance. Cards are cheap when paid in full and expensive the moment they are not. Rewards on a purchase are typically worth a low single-digit percentage. Interest on a balance carried for several months runs many times that. Any owner treating a card as medium-term borrowing is paying a rate designed for people who pay off in thirty days.
Getting actual cash. Cash advances are the worst feature of any card. There is a fee on the withdrawal, no grace period, and interest accrues immediately. If you need money in the business account for payroll or a supplier deposit, the card is close to the most expensive route available.
What a line of credit does differently
A business line of credit is revolving, like a card, with an approved limit you draw against as needed and interest charged only on what you have actually drawn. Leave it untouched and it costs little or nothing.
The differences that matter are size, cash access and rate. Approved limits generally run well above card limits, which puts equipment, inventory and payroll comfortably in range. Funds arrive in the business bank account rather than sitting behind a cash advance fee. And rates on a drawn balance are normally far below what a card charges on a carried one.
What you give up is convenience. There is an application rather than an instant swipe, approval depends on trading history and revenue, and there are no rewards. A line of credit is a funding tool. A card is a payment tool that happens to lend.
Owners are planning bigger purchases
This distinction is becoming more relevant. The NFIB’s Small Business Economic Trends survey for July 2026 found that 25% of small business owners planned capital outlays in the next six months, up five points from June and the strongest reading since December 2024.
Capital outlays means equipment, vehicles, facilities. Those are exactly the purchases that sit above a card limit, and a quarter of small businesses are planning them.
Which one fits
Reach for the card when the spending is routine, repeats monthly, and gets cleared in full. Subscriptions, fuel, flights, small supplier orders, client entertainment. This is where the rewards are real money and the float is free.
Reach for the line of credit when the amount is large relative to your card limit, when repayment will take longer than a statement cycle, when you need cash rather than a payment method, or when the timing is seasonal and you are bridging a quiet quarter.
Most established businesses end up with both
The two products solve different problems, and running them together usually works better than forcing one to cover everything. Day-to-day spending goes on the card and gets paid off monthly, so the rewards accumulate and no interest is ever charged. Anything larger or slower moves to the line of credit at a rate built for borrowing.
One warning worth taking seriously. A line of credit is revolving, which makes it easy to treat like a second card: draw a little, repay the minimum, draw again. Do that for a year and a facility meant for short-term gaps has quietly become permanent debt with a balance that never reaches zero. Decide up front what each draw is for and roughly when it gets cleared. A revolving limit rewards discipline and punishes drift.
Frequently asked questions
- Is a business credit card easier to get than a line of credit? Usually yes. Card applications often lean heavily on the owner’s personal credit and can be approved in minutes. A line of credit is assessed more on business revenue and trading history, so it takes longer but tends to produce a larger limit.
- Does a business credit card affect my personal credit score? Often, yes. Many small business cards require a personal guarantee, and some issuers report activity to personal credit bureaus. High balances relative to the limit can show up on your personal file even though the spending is entirely commercial.
- Can I use a business line of credit to pay off a credit card balance? It is possible, and the interest saving can be meaningful if the card balance is large and carried. The thing to avoid is clearing the card and then rebuilding the balance, which leaves you owing on both.
- Do business credit cards have the same protections as personal ones? Not always. Several rules that apply to consumer cards were written for consumer credit and do not automatically extend to business accounts, so terms on business cards can be changed more freely. Read the agreement rather than assuming your personal card protections carry over.
- Should a new business apply for a line of credit straight away? Most lenders want to see a trading history first, commonly six months or more of revenue. Newer businesses often start with a card, build a record, and add a line of credit once the numbers support a useful limit.
