An overdraft gives you a revolving credit line you can draw anytime for any business purpose. Invoice finance advances cash against specific unpaid invoices. Overdrafts suit general cash flow gaps; invoice finance suits businesses with large outstanding invoices and long debtor days (60+ days).

Cost Comparison: Real Numbers
Let us compare the actual cost of accessing $50,000 through each product for 30 days.
Worked Example: $50,000 for 30 Days
Business Overdraft ($50K drawn at 22% p.a.):
$50,000 x 22% / 365 x 30 = $904 in interest
Invoice Finance ($50K invoice at 2% per month, 85% advance):
Advance: $42,500 (85% of $50K). Fee: $50,000 x 2% = $1,000
You only receive $42,500 but pay fees on the full $50K invoice.
Result: The overdraft costs $96 less and gives you the full $50,000. But if you have $200,000 in unpaid invoices, invoice finance lets you access $170,000, far more than most unsecured overdraft limits.
The cost difference narrows when you factor in that invoice finance limits are tied to your receivables. A business with $300,000 in outstanding invoices could access $240,000 through invoice finance, while an unsecured overdraft might cap at $150,000.
When an Overdraft Is the Better Choice
Choose an overdraft when:
- Your cash flow gaps are general, not tied to specific invoices
- You need funds for payroll, rent, stock, or supplier payments
- You want flexibility to draw and repay without restrictions
- Your invoicing is mostly B2C or small-value (under $1,000 per invoice)
- You need money fast, within 24-48 hours
- Your customers should not know about your financing arrangements
- You have been trading for 6 months or more with $6,000+ monthly revenue
Best fit: Retail, hospitality, trades, services, and any business where revenue comes from many small transactions rather than a few large invoices. See our line of credit page for a similar revolving option.
When Invoice Finance Is the Better Choice
Choose invoice finance when:
- You invoice other businesses (B2B) for large amounts ($5,000+ per invoice)
- Your customers take 30-90 days to pay and this creates cash flow pressure
- Your receivables are growing faster than your working capital
- You need to borrow more than $150,000 and do not own property
- Your business is growing quickly and you need financing that scales with revenue
- You are comfortable with your customers knowing about the arrangement (for disclosed facilities)
Invoice finance works particularly well for transport, logistics, labour hire, manufacturing, and wholesale businesses where debtor days are long and invoice values are high.

Yes. Many businesses on the OverdraftMe panel use both products at the same time. A common structure is a $50,000-$100,000 overdraft for day-to-day expenses (payroll, rent, stock) and an invoice finance facility to accelerate payment on larger B2B invoices.
The overdraft provides general liquidity. The invoice finance facility provides additional capacity that grows with your receivables. Together, they give you more working capital than either product alone.
Eligibility: To run both facilities, lenders need to see that your total debt service is supportable from cash flow. A business doing $50,000/month in revenue could typically support a $75K overdraft and a $100K invoice finance facility simultaneously.
Frequently Asked Questions
Yes. Many businesses use both. The overdraft covers general cash flow gaps and short-term expenses. Invoice finance accelerates payment on large outstanding invoices. They serve different purposes and can work together.
Invoice finance typically costs 1-3% of the invoice value per month, which can equate to 12-36% p.a. An overdraft at 18-24% p.a. is often cheaper if you only need short-term access to funds. But invoice finance lets you borrow more because it is tied to your receivables.
It depends on the type. With disclosed invoice finance, your customers pay the finance company directly and know about the arrangement. With confidential invoice finance, you collect payment as normal and your customers are not aware. Confidential facilities are more expensive.
Most invoice finance providers require a minimum of $50,000 in monthly invoices. Individual invoices typically need to be at least $1,000. Smaller invoicing volumes are better suited to a business overdraft.
A business overdraft is typically faster. Approval in 24-48 hours and funds available immediately. Invoice finance takes 1-2 weeks to set up because the provider needs to verify your debtors, review your invoicing system, and sometimes notify your customers.
