Business lines of credit and business credit cards both give a business money it can draw on without applying each time, and both charge interest only on what is used. The difference is what they are built for. A business credit card is a payment tool with a short line of credit attached: it pays suppliers at the point of sale, gives staff a way to spend within limits, and charges no interest if the balance is cleared each month. A business line of credit is a working capital facility: a larger limit, drawn into the business's bank account, priced for balances that are carried for weeks or months rather than days.
Used for the right job, each is cheap. Used for the wrong one, a card becomes the most expensive debt a business carries, and a line of credit becomes an overdraft that never clears. This guide sets the two side by side and shows where each earns its place.
The quickest way to tell them apart is to ask where the money goes. A card pays a merchant; a line of credit lands in the business's own account and can pay anyone, including wages, the ATO and a supplier who takes bank transfer only. The second question is how long the money is owed: a card is built for a balance that is cleared inside a statement cycle, a line of credit for one that is carried for longer and repaid when the receivables come in.
A business line of credit is an approved limit the business can draw on, repay and draw on again for as long as the facility runs. Interest is charged on the drawn balance, usually calculated daily, so a limit of $50,000 with $5,000 drawn costs interest on $5,000. Some lenders add a fee on the limit itself whether it is used or not, which is the first thing to check. Repayments are flexible on most bank facilities: interest must be paid, and the principal can be paid down when cash allows or held at the limit through a slow quarter. Online lenders often set a repayment schedule on each draw instead.
Secured lines of credit, backed by property or other business assets, carry the lowest rates and the largest limits and sit mostly with banks. Unsecured lines from online lenders are quicker to open, smaller and priced higher; they are decided on bank statements and credit history, and most ask the directors for a personal guarantee. Either way the facility suits the gap between paying suppliers and being paid by customers, a stock build before the season, or a piece of equipment that will be paid off within months.
| Business line of credit | Business credit card | |
|---|---|---|
| Built for | Working capital drawn into the bank account | Paying for purchases at the point of sale |
| Interest | On the drawn balance from the day it is drawn; lower on secured facilities | On purchases only if the balance is not cleared by the due date; Moneysmart puts the average card rate at over 18% |
| Interest-free period | None | Up to a set number of days on purchases, only when the full closing balance is paid on time |
| Limit | Larger; secured limits can run well into six figures | Smaller, set on the business's credit profile |
| Security | Secured or unsecured | Unsecured, with a personal guarantee on most small business cards |
| Fees | Establishment fee; sometimes a line fee on the limit | Annual fee; cash advance fees; foreign transaction fees; late payment fees |
| Paying wages, tax or a supplier who takes transfer only | Yes, by transfer | Tax can be paid by card through the ATO for a card fee (the issuer's terms say whether it counts as a purchase); wages and transfer-only suppliers need a cash advance or a fee-charging payment service |
| Repayment | Interest must be paid; principal is flexible | Minimum monthly repayment; interest on any balance carried |
Business cards and lines of credit sit outside the National Credit Code, so the consumer card protections, such as the ban on backdating interest into the interest-free period, do not automatically apply; the terms are the business's to read.
A card is unbeatable for purchases the business will pay for in full when the statement arrives. Fuel, software, travel, online orders and small supplier invoices go on the card, the balance is cleared by the due date, and the business has had the use of the money for the interest-free period at no cost. Staff cards with individual limits keep spending controlled without the owner approving every purchase, and the statement feeds straight into the accounting software with the receipts attached. Rewards can be worth something for a business with high card spend, provided the annual fee and any surcharge do not eat them.
The card stops winning the moment a balance is carried. Interest then runs on the unpaid balance, and on some business cards it is backdated to the purchase date; the card's terms say which. The interest-free days disappear until the balance is cleared, and the rate is a card rate. A cash advance is worse still on most cards: interest from day one, a fee on top and no interest-free period.
A line of credit wins on anything the business will owe for longer than a statement cycle, anything that has to be paid by transfer, and anything larger than a card limit. Wages while a big invoice is outstanding, a deposit to a supplier who does not take cards, a quarterly tax bill that lands before the receivables do, a stock order ahead of the season: each is a draw on the line, repaid when the money comes in, at a rate set for carried balances rather than a card rate. On a secured facility the gap is wide; on an unsecured line it narrows, and the total cost with any line fee is the figure to compare.
It also wins on discipline. A line of credit sits in the business's banking, is drawn deliberately and shows as a balance to be repaid; a card balance accumulates from dozens of small decisions and is easy to let ride at the minimum repayment.
Business lines of credit come in both forms. A secured line is backed by property, equipment, receivables or a charge over the business's assets, registered on the Personal Property Securities Register for anything that is not land. The lender's lower risk shows up as a lower rate and a higher limit, at the cost of a slower approval and an asset on the line. An unsecured line relies on cash flow and credit history, can open in days rather than weeks, and costs more per dollar drawn. A business with an asset it would keep anyway and a facility it will use regularly usually does better securing it; a business that wants a modest limit for occasional use may prefer the speed of an unsecured line and pay the difference.
Applying takes a few minutes online, and a quote from a broker compares line of credit options from different lenders before any full application. Most lenders want an established business trading for at least six months with a record of income, an ABN, identification for the directors and recent bank statements; low-doc facilities stop there, while bank facilities and larger limits ask for financial statements, tax returns and, for a secured line, details of the asset. Lenders also read the tax position: the ATO can report a business tax debt of $100,000 or more that is overdue by more than 90 days to credit reporting bureaus where the business is not engaging with it, and a payment plan that is being kept stops the disclosure.
The businesses that pay least for working capital tend to run both and keep them in their lanes: the card for purchases that will be cleared in full each month, the line of credit for the balance that is genuinely being carried, and nothing on a card cash advance. Review the line fee and the rate each year, because a facility opened at a start-up rate does not have to stay at one, and market rates move (the RBA cash rate rose to 4.35% in May 2026 and was held there in June and August).
