Invoice Finance vs Overdraft vs Line of Credit: Pick the Right Cash Flow Tool
Three products, three very different cost shapes. Here's exactly when each one fits — with 2026 rates, eligibility and a decision framework that fits on one page.
Chasing Invoices or Burning Your Overdraft? There's a Better Way to Manage Cash Flow.
Invoice finance, business overdrafts, and lines of credit all solve cash flow problems — but they work completely differently, cost very different amounts, and suit very different businesses. The wrong choice can cost you tens of thousands of dollars a year in fees you don't need to pay. This guide breaks down all three products with real 2026 rates, eligibility requirements, and a decision framework so you pick the one that actually fits your situation.
Why Cash Flow Is the Business Loan Problem That Never Goes Away
Here's the inconvenient truth: profitable businesses go bust every year. Not because they're losing money — because the money arrives in the wrong order.
You pay wages on Friday. You pay suppliers on 30-day terms. Your client pays your invoice on 60-day terms. The gap in between is where otherwise healthy businesses die.
Australian insolvency data from the RBA (October 2025) shows elevated stress particularly in construction and hospitality — two industries where the invoice-to-cash gap is widest and least predictable. These aren't failing businesses. They're businesses that ran out of runway while waiting to be paid.
Three products exist specifically to fix this problem. They are:
- Invoice finance — you unlock cash tied up in unpaid invoices, usually within 24–48 hours
- Business overdraft — a pre-set credit limit attached to your bank account as a safety buffer
- Line of credit (LOC) — a revolving pool of pre-approved funds you draw and repay as needed
Each addresses a different cash flow shape. Using the wrong one is like buying flood insurance when your problem is drought.
The Three Products Explained in Plain English
Invoice Finance
You've raised an invoice. The customer has 30, 60, or 90 days to pay. Invoice finance lets you sell that receivable to a lender right now and get paid today — typically 80%–95% of the invoice value upfront. The lender collects from your customer, then pays you the remaining balance minus their fee.
ScotPac advances up to 95% of invoice value. Most providers advance 80%–90%.
Funds hit your account within 24–48 hours of submitting the invoice. The lender takes a fee — typically 3%–8% per 30 days of invoice value — then releases the balance once your customer pays.
There are two flavours:
- Invoice factoring — the lender manages collections and your customers know about it (disclosed)
- Invoice discounting — you manage collections yourself; your customers typically don't know (undisclosed)
No property security required. The invoices themselves are the collateral.
Business Overdraft
An overdraft is a credit limit attached to your existing transaction account. When your balance hits zero, you keep drawing — up to the approved limit. You only pay interest on what you actually use.
Limits typically run from $5,000 to $100,000+. Larger limits (generally above $50,000) usually require property security. For smaller limits, some lenders will approve based on trading history alone.
The trap: lenders charge a line fee on your full approved limit, not just what you've drawn. More on this below.
Line of Credit
A line of credit is a pre-approved pool of funds — say $50,000 or $150,000 — that you draw from, repay, and draw again without reapplying each time.
Unlike an overdraft (which is attached to a bank account), a LOC is a standalone facility. Interest accrues only on the drawn balance. Once repaid, those funds are available again. It's revolving, flexible, and doesn't require you to justify each draw.
Eligibility is typically lighter than an overdraft: often just 12 months ABN history and $10,000/month in revenue.
Side-by-Side Comparison Table
| Dimension | Invoice Finance | Business Overdraft | Line of Credit |
|---|---|---|---|
| Security required | Invoices (no property needed) | Often property for limits >$50K | Often unsecured up to ~$150K |
| Typical cost | 3%–8% per 30 days (effectively 36%–96% p.a.) | 14.55%–16%+ p.a. + line fee | 14.55%–22% p.a. |
| Speed of access | 24–48 hours per invoice | Immediate (once set up) | Immediate (once set up) |
| Flexibility | Tied to specific invoices | Flexible within limit | Flexible within limit |
| Eligibility | Invoices to business clients | Often 2+ years trading + property | Often 12 months ABN + $10K/month revenue |
| Best use case | Specific unpaid invoices | Unexpected short-term gaps | Regular but unpredictable cash needs |
| Who offers it | ScotPac, Fifo Capital, Earlypay | ANZ, NAB, Dynamoney, Shift | OnDeck, Dynamoney, Prospa, Shift |
| Maximum facility size | Up to several million (scales with invoices) | Typically $5K–$250K | Typically $5K–$500K |
| Interest charged on | Fee per invoice | Drawn balance only (+ line fee on limit) | Drawn balance only |
Decision Framework: Which Product Fits Your Cash Flow Problem?
Don't start with the product. Start with the problem.
"I have outstanding invoices but need cash now" → Invoice finance. You have the asset — unpaid receivables. Invoice finance converts them to cash in 24–48 hours. No need to take on open-ended debt.
"I need a buffer for unexpected costs — my cash flow is mostly fine" → Business overdraft. You want a safety net, not a permanent facility. An overdraft sits there unused (but not free — watch the line fee) and activates when you need it.
"My cash needs are regular but unpredictable in timing — I'm always juggling" → Line of credit. Revolving, no reapplication, interest only on what you draw. Built for this exact problem.
"I'm in construction or trades" → Invoice finance is the natural fit. You raise large invoices. Customers take 60–90 days to pay. Progress claim cycles kill cash flow. Invoice finance matches the rhythm of how you work.
"I'm in retail or hospitality" → Overdraft or LOC for seasonal gaps. You don't typically have B2B invoices to finance, so invoice finance usually won't apply.
"I'm a professional services firm — consulting, law, accounting" → Line of credit for work-in-progress (WIP) gaps. You have irregular billing cycles and need flexible working capital that doesn't depend on specific invoice submission.
The Cost Reality: Fees and Rates for Each Product (2026)
Invoice Finance
Invoice finance is priced per invoice, not per annum. The typical range is 3%–8% per 30 days of invoice value.
Worked example: you submit a $50,000 invoice. The lender advances 85% ($42,500). Their fee is 4% for 30 days = $2,000. When your customer pays at day 45, you receive the remaining $7,500 minus $3,000 in fees (4% × 1.5 months). Total cost: $3,000 on a $42,500 advance.
Annualised, that's 36%–96% p.a. — far higher than overdraft rates on paper. But this isn't an ongoing debt. You're paying for speed and the removal of collection risk on a specific transaction. The comparison only makes sense if you'd otherwise be carrying an overdraft balance for the same period.
Business Overdraft
Current rates from Money.com.au (May 2026):
| Lender | Rate |
|---|---|
| Dynamoney Secured | From 14.55% p.a. |
| Shift | From 14.95% p.a. |
| ANZ | From 15.95% p.a. |
| NAB QuickBiz | From 16.00% p.a. |
The line fee trap: Most overdraft facilities charge a line fee on the full approved limit — regardless of how much you've drawn. If you have a $100,000 overdraft at a 1.5% annual line fee, you're paying $1,500/year whether you've drawn $1 or $100,000. This is a cost that doesn't show up in the headline interest rate.
Line of Credit
Rates (May 2026) typically range from 14.55% (Dynamoney) to 22% p.a. for non-bank lenders, with major banks sitting at the lower end for secured facilities.
Interest accrues on drawn balance only — no line fee equivalent. If you draw $30,000 from a $100,000 facility, you pay interest on $30,000.
The RBA Context
The RBA cash rate sits at 4.35% (raised May 6, 2026). Business lending rates reflect a substantial risk premium above this — typically 10–18 percentage points for SME products. Non-bank lenders have increased their share of SME lending strongly since early 2022, driven by faster approvals and lighter eligibility requirements.
Eligibility Differences: What Each Product Requires
Invoice Finance
- You invoice business clients (B2B only — not retail consumers)
- Invoices are to creditworthy businesses (the lender assesses your customer's credit, not just yours)
- Minimum invoice value varies: some providers accept invoices from $1,000; others have minimums of $50,000–$200,000 per invoice
- Trading history: typically 6–12 months, though some providers work with earlier-stage businesses
- No property security required
Business Overdraft
- Most banks require 2+ years of trading history
- Limits above $50,000 typically require property as security (residential or commercial)
- You need an existing business transaction account with the lender (or willingness to switch)
- Revenue requirements vary by lender but are generally more stringent than LOC providers
Line of Credit
- Typically 12 months ABN minimum
- Revenue: usually $10,000/month or above ($120,000/year)
- Unsecured options available up to $150,000–$250,000 with some non-bank lenders
- No specific invoice requirement — general business cash flow is assessed
The Property Security Problem
Banks love property security. It de-risks their loan book at your expense.
For businesses that have been running for less than two years, or whose owners don't have property to pledge, overdraft access is extremely limited. The major banks will typically decline, and non-bank options come at higher rates.
Invoice finance sidesteps this entirely. The invoices are the security. If your customer doesn't pay, the lender's recourse is to the invoice — not your house. This makes invoice finance the most accessible working capital option for:
- Businesses less than two years old
- Business owners who don't own property
- Businesses whose owners don't want to mix personal and business risk
Lines of credit from non-bank lenders have also moved away from mandatory property security for smaller facilities. OnDeck, Prospa, and similar lenders approve unsecured LOCs based on business revenue and cash flow data.
The practical result: if you're a young business without property, your realistic options are invoice finance (if you have B2B invoices) or an unsecured LOC (if you have 12 months of trading history and sufficient revenue).
Industry Guide: Which Product Suits Your Business Type?
Construction and Trades
Invoice finance is the natural fit. Progress claims, retention payments, and 60–90 day payment terms create structural cash flow gaps. You have large, specific invoices that can be financed immediately. The RBA (October 2025) flagged construction as one of the most stressed SME sectors — and most of that stress is timing-driven, not profitability-driven.
Disclosure to clients matters here: many construction operators use undisclosed invoice discounting to keep the financing arrangement invisible to clients.
Retail and Hospitality
These businesses typically don't have B2B invoices to finance. Their cash flow problem is seasonal (peak periods vs. dead months) and inventory-driven. An overdraft or LOC fits better — a standing facility you draw during quiet periods and repay during strong trading.
Professional Services (Consulting, Law, Accounting, IT)
Irregular billing cycles and WIP gaps make a line of credit the cleaner solution. You don't always have specific invoices ready to submit (especially early in a project), but you need cash to cover wages and overheads during long project cycles.
Manufacturing
Often a combination approach: invoice finance on finished goods shipped to customers, plus a LOC for raw material procurement. Large manufacturers with consistent volume sometimes negotiate specific trade finance or inventory finance facilities, but for most SME manufacturers, these two products cover the gap.
Pitfalls to Avoid with Each Product
Invoice Finance Pitfalls
Customer notification. With factoring (disclosed), your lender contacts your customers directly for payment. Some clients react badly to this. If the relationship matters, use undisclosed invoice discounting instead — but check whether the lender offers it (not all do, and it usually requires a larger facility).
Bad debt risk. Check whether your facility is recourse or non-recourse. With recourse factoring, if your customer doesn't pay, you pay the lender back. With non-recourse, the lender absorbs the loss. Non-recourse is more expensive but eliminates your credit risk on that invoice.
Minimum volume requirements. Some providers require a minimum monthly turnover (e.g., $50,000/month in invoices). If you're below this, you may be limited to selective invoice finance (single-invoice factoring), which costs more.
Overdraft Pitfalls
The line fee trap. As noted above: line fees on the full approved limit are a real cost that doesn't appear in the interest rate comparison. A $100,000 overdraft at 15.95% p.a. with a 1.5% line fee costs $1,500 before you draw a cent.
Treating it as permanent finance. An overdraft is designed for short-term gaps — days to weeks, not months. If your overdraft is permanently maxed out, you've got a structural cash flow problem that an overdraft is papering over. Refinancing into a term loan is usually cheaper for long-term needs.
Line of Credit Pitfalls
Structural debt dependency. This is the big one. A revolving LOC makes it easy to keep drawing and never fully repay. Over time, you can end up carrying a permanently elevated balance — effectively a term debt that you're paying higher revolving rates on. Review your LOC balance quarterly. If it's never getting below 50% of your limit, consider converting some of it to a term loan at a lower rate.
Draw discipline. The flexibility of a LOC can lead to using it for non-cash-flow purposes (equipment, fit-outs, long-term investments). Those purchases should be financed with term products matched to the asset life, not a revolving facility.

Frequently Asked Questions
What is invoice finance and how does it work for Australian SMEs?
Invoice finance lets you convert unpaid B2B invoices into immediate cash. You submit an invoice to a lender, they advance 80%–95% of the invoice value within 24–48 hours, then collect from your customer when payment is due. The lender deducts their fee (typically 3%–8% per 30 days) from the remaining balance. No property security is required — the invoices are the collateral.
Is invoice finance more expensive than a business overdraft?
On an annualised basis, yes — invoice finance costs 36%–96% p.a. equivalent versus 14.55%–16%+ p.a. for a business overdraft. But the comparison isn't straightforward. Invoice finance eliminates the credit risk on that invoice (with non-recourse facilities), gives you the cash in 24 hours without needing property security, and doesn't leave you carrying ongoing debt. For a business without property or credit history, invoice finance may be the only realistic option at any price.
Can I get a business overdraft without using my home as security?
For limits up to around $50,000, some lenders approve overdrafts based on trading history alone. Dynamoney and Shift are non-bank examples offering secured-from-14.55% and unsecured options. For limits above $50,000–$100,000 at major banks, property security is typically required. If you want a larger unsecured facility, a line of credit from a non-bank lender is usually more accessible.
What is the difference between invoice factoring and invoice discounting?
Both are forms of invoice finance, but they differ in who manages collections and whether your customers know. With invoice factoring, the lender takes over collecting payment and notifies your customers (disclosed). With invoice discounting, you continue to manage collections yourself and your customers typically don't know (undisclosed). Discounting preserves the customer relationship but usually requires a larger facility or stronger business history.
Can I have both a line of credit and an invoice finance facility at the same time?
Yes. Many businesses run both — using invoice finance for specific large invoices and a LOC for general operating costs. The lenders are usually different, and there's no rule against it. Make sure you understand the total cost of both facilities and that you're not double-financing the same cash flow gap.
What happens to my invoice finance if a customer doesn't pay?
It depends on your agreement. With recourse invoice finance (the most common structure), you're liable to repay the advance if your customer defaults. With non-recourse invoice finance, the lender absorbs the credit risk. Non-recourse costs more but protects you if a major client fails. Always confirm which structure you're signing up for before committing.
Is a business line of credit the same as a business overdraft?
Not exactly. Both are revolving facilities and both charge interest on the drawn balance only. The key differences: an overdraft is typically attached to your business bank account and activates when your balance goes negative; a LOC is a standalone facility you draw from separately. Overdrafts often require bank account switching and longer trading history. LOCs from non-bank lenders are generally more accessible with lighter eligibility requirements.
How quickly can I access funds through invoice finance?
Most providers fund within 24–48 hours of invoice submission and approval. For established relationships with an existing invoice finance provider, same-day funding is common. The main delays come from the lender's credit check on your customer — if you're submitting invoices from a customer already approved in their system, turnaround is faster.
Which is best for a construction or trade business — invoice finance or overdraft?
Invoice finance. Construction businesses run on progress claims with 60–90 day payment terms, high single-invoice values, and severe cash flow timing gaps. Invoice finance is designed for exactly this structure. An overdraft might help smooth smaller gaps, but won't match the scale of a $200,000 progress claim sitting unpaid for 60 days. The RBA flagged construction as one of the most stressed SME sectors in October 2025 — most of that stress is cash flow timing, not underlying profitability.
What's the minimum invoice value needed for invoice finance in Australia?
It varies by provider. Some selective invoice finance platforms (single-invoice factoring) accept invoices from as low as $1,000–$5,000. Larger facility providers like ScotPac often have practical minimums of $50,000–$200,000 per invoice or require a minimum monthly invoice volume (e.g., $50,000/month). If your invoices are small, look for specialist SME invoice finance platforms rather than institutional factoring houses.
