The construction payment cycle

A construction company's costs run ahead of its income by design. Payroll is weekly, materials are bought up front, plant is hired by the day and subcontractors expect timely payment, yet progress claims must be certified before funds are released, and retentions sit unpaid until completion. A business overdraft is made for this cycle. Linked to your trading account, it lets you draw below zero up to an approved limit and return to surplus as claims are paid, with interest applying only to the negative balance while it is used. That keeps multiple sites running smoothly, so a delayed certification does not stall labour or hold up a critical material delivery.

Where the buffer helps most

Construction companies lean on an overdraft across the pressure points of a project. It covers payroll and subcontractor claims when a progress payment is late, funds material and plant costs during the ramp-up of a new job, and bridges the cash held back by retentions on completed work. It can absorb the cost of variations that expand a contract's scope, cover overheads such as insurance, compliance and vehicles through a lean month, and provide the working capital to mobilise when you win new work. Because the limit refreshes as income arrives, the overdraft is available every time a new timing gap opens, which suits the overlapping schedules of a busy company.

How an overdraft compares

An overdraft is prized for immediacy, because it lives on your trading account and activates the moment the balance goes negative, with nothing to arrange each time. That makes it well suited to frequent, short-term gaps. A line of credit is a separate revolving facility you draw on deliberately, sometimes offering a larger limit. A term loan is a fixed lump sum with scheduled repayments, better for a one-off purchase like heavy equipment. Invoice or progress-claim finance can also release cash tied up in certified work. Most construction companies combine an overdraft for daily flexibility with other products for bigger, defined needs, and comparing them ensures the structure fits.

Secured or unsecured limits

You can arrange an overdraft with or without security. Unsecured overdrafts require no property collateral and are typically available up to around $500,000, assessed on turnover, trading history and account conduct. That appeals to construction companies that prefer to keep property free or have already committed it. A secured overdraft, backed by property or business assets, can unlock a higher limit and often keener pricing for established operators with equity. Across the market, business funding runs from around $5,000 up to $5 million depending on product and lender. The appropriate limit depends on the value of your active contracts and how long payments typically take to be certified and released.

What lenders assess

Lenders generally want an active ABN, a minimum trading history (often between six and twelve months) and steady turnover through the business account. For a construction company they consider the reliability of progress payments, the strength and spread of the head contractors or clients you work for and how the account is managed. Low-doc options may use bank statements or BAS in place of full financials, which helps companies without current accountant-prepared figures. Newer businesses can still qualify subject to criteria. All pricing is indicative and profile-dependent, so approval and rate are subject to a lender assessing your specific circumstances, security and requested limit.

Amounts, speed and pricing

The overdraft limit you can access reflects turnover, the reliability of contract income and whether you offer security. Indicative business-lending rates start from around 7.49% p.a. for stronger secured facilities, with unsecured and short-term products priced higher depending on turnover, term, security and credit profile. Overdrafts are usually reviewed periodically rather than run to a fixed end date and stay available for ongoing use. For eligible applicants, same-day pre-approval and funding within 24 to 48 hours may be possible. That means a buffer can be ready before the next payroll or material order rather than after weeks of negotiating with a single bank.
