When a working capital facility beats a bank overdraft

• An overdraft limit is capped by your security, not your sales. RBA data: half of small SME loans are property-secured.
• Growth widens the gap an overdraft can't close. OctetDebtor releases up to 85% of invoice value within 24 hours.
• The slowest payers are getting slower: the 95th-percentile payment time to small suppliers rose from 58 to 64 days.
• Late payment has a price. Employing small businesses lost an average of $15,257 last financial year to overdue invoices.
• Compare total cost against actual usage. An overdraft isn't automatically cheaper once facility fees and unused capacity are counted.

An overdraft limit is a fixed number, and at a bank that number is usually a function of what security you can pledge rather than how the business is trading. Reserve Bank research published in October 2025 found around half of small-sized SME loans are secured by residential property, and that residentially-secured loans are on average four and a half times larger than those secured by other assets. One in five SMEs has struck difficulty obtaining finance, with the requirement to pledge property or personal assets among the most cited barriers.

The reason is structural.

The businesses that outgrow an overdraft fastest are usually the ones winning work. A large new contract means wages, stock, freight and subcontractors paid weeks before the invoice is settled. A fixed overdraft limit does not move when that happens.

A receivables-backed facility does.

"An OctetDebtor facility releases up to 85 percent of the value of unpaid invoices within 24 hours, and available funding expands as the sales ledger expands," explains Allan. "This can be a better structural fit for seasonal peaks, tender wins, and businesses hiring ahead of revenue."

Confidential invoice discounting options are available when a business prefers that its customers not see that a financier is involved.

Payment terms are set by whoever holds the leverage. The Payment Times Reporting Regulator reported in January 2026 that the average time for a large business to pay 95% of its small business invoices had risen from 58 days to 64 days. While average payment times held broadly steady, it is the slowest payers who got slower. This is precisely the tail that breaks a fixed overdraft limit.

Xero research published in March 2026 put a number on the cost. A survey of 500 employing Australian small businesses found they lost an average of $15,257 to late customer payments over the prior financial year. Fifty-eight per cent named customer payments their biggest cash flow challenge.

Allan states: "If your working capital gap is created by other people's payment behaviour, financing the receivables addresses the cause rather than the symptom."

Releasing property security is a different outcome from simply accessing more funding, and for many business owners it is the more valuable one.

An invoice finance facility can be used to replace an existing overdraft, reduce reliance on traditional bank debt, and release residential property securities.

According to Allan the wording matters: “Reduce, not eliminate,” he says. “Most facilities in this market still involve security over the business itself, so what changes is which assets carry the risk.”

The market has been moving this way for several years. Non-bank lenders have steadily increased their share of SME lending, and the RBA credits that competition with much of the recent improvement in SME access to finance: faster approvals, simpler applications, and a broader range of structures.

Rather than starting with what property is available, non-banks more often assess transaction data and cash flow performance.

An overdraft remains appropriate where the gap is genuinely small and short, where the business does not invoice other businesses on terms, or where a consistently low drawn balance means facility fees would outweigh the benefit.

Debtor finance is priced differently, typically an interest component on what funds are drawn plus a service fee, so compare total cost against actual usage rather than headline rate.

With the cash rate at 4.35% (as at August 2026) and banks more selective, speed and certainty of funding increasingly matter as much as price.

"So the question is not which product is cheaper in the abstract,” says Allan. “It is whether your funding limit should be tied to your receivables, which is an asset you already own and are already growing, or to one you would rather not put at risk.”
