A business overdraft is a revolving line of credit that lets you draw funds up to an approved limit and repay as cash flows in. It's the most flexible working capital tool available to Australian SMEs - but it's not perfect for every situation. Here's an honest breakdown from a broker who arranges them every day.
An overdraft makes sense when your business has irregular cash flow timing - money coming in doesn't always align with money going out. This covers most Australian SMEs: tradies waiting on progress claims, cafes managing quiet weeks, recruiters funding contractor payroll before client invoices land, and any business dealing with seasonal dips.
It also makes sense as a safety net. Many businesses set up an overdraft and rarely use it - but when an unexpected expense hits or a client pays late, the facility is there. The cost of having it ($1K-$2K/year in line fees) is a fraction of the cost of missing payroll, losing a supplier discount, or copping an ATO penalty.
If you need to buy a specific asset (vehicle, equipment, fitout), a term loan or asset finance will almost always be cheaper. The fixed rate and structured repayments also make budgeting easier.
If your business is consistently unprofitable and the overdraft is being used to cover losses rather than timing gaps, it's a bandaid - not a solution. An overdraft should bridge temporary gaps, not fund ongoing deficits.
If you only need funds once for a specific purpose and won't need ongoing access, a term loan avoids the line fee and usually offers a lower rate.

| Fixed repayments? | No - flexible | Yes - fixed | Yes - ATO sets | Minimum payment |
| Approval speed | 1-24 hours | 1-5 days | 1-7 days | Instant if existing |

| Best for | Ongoing cash flow | One-off purchases | Last resort for tax | Small purchases |
A business overdraft is the best tool for managing cash flow timing in an Australian SME. The advantages - flexibility, tax deductibility, speed, reusability - outweigh the disadvantages for most businesses. The key is using it correctly: as a short-term buffer for cash flow gaps, not as permanent debt.

Check your eligibility →The main advantages are flexibility (draw and repay as needed), you only pay interest on what you use, the facility is reusable without reapplying, interest is tax deductible, and approval can happen within hours through a non-bank lender.
Disadvantages include higher interest rates than secured term loans, annual review requirements where the lender can reduce or cancel the facility, line fees charged on the full limit even when unused, and the temptation to rely on it as permanent funding rather than short-term cash flow management.
It depends on the purpose. An overdraft is better for ongoing cash flow management - paying suppliers, covering payroll gaps, managing seasonal dips. A business loan is better for one-off purchases like equipment, vehicles, or fitouts where you know the exact amount and repayment timeline.
Yes. Interest, line fees, and establishment fees on a business overdraft used for business purposes are generally tax deductible under Australian tax law. This is a significant advantage over alternatives like ATO payment plans, where the General Interest Charge is no longer deductible since 1 July 2025.
Yes. Most business overdrafts are subject to annual review. The lender can reduce your limit or cancel the facility if your business performance deteriorates, your credit profile changes, or you breach the facility terms. This is one of the key disadvantages compared to a term loan with fixed repayments.
