Managing the payday super cash flow gap when clients pay in 60 days
The timing problem nobody planned for
Most construction businesses invoice on progress or completion and wait, sometimes 30, 60 or 90 days, for the client to pay. That model worked when superannuation was paid quarterly, because the cash cycle and super cycle moved at roughly the same pace.
From 1 July 2026, that changed. Employers now pay superannuation guarantee for each payday, and contributions must reach employees' super funds within seven business days. The quarterly buffer is gone.
If you pay wages fortnightly and invoice on 60-day terms, you are now making super payments every fortnight on work the client has not yet paid for. The super obligation runs ahead of your cash receipts, and that gap must be funded from somewhere.

How the gap compounds across a crew
The exposure scales with headcount and payment frequency. A weekly payroll creates more super payment dates than a fortnightly one, and a crew of ten generates more cash outflow than a crew of three.
Each payday triggers a super obligation of 12 per cent of qualifying earnings. If you have five workers on a combined fortnightly payroll of $15,000, super of $1,800 must leave your account within seven business days. If the job those workers completed is invoiced on 60-day terms, that $1,800 is funding work you will not be paid for until two months later.
Repeat that cycle across multiple jobs, and the cumulative super payments sitting in front of unpaid invoices can quickly exceed what many businesses hold in working capital.
Late payment carries regulatory consequences
The super guarantee charge applies when contributions are not received by the super fund within the required timeframe. The charge includes the unpaid super, interest that compounds daily at the general interest charge rate, and an administrative uplift.
Directors of companies with unpaid superannuation may face personal liability under director penalty provisions. If you receive a director penalty notice, seek advice from a registered tax agent or legal adviser promptly.
These consequences apply from the day a payment is late, regardless of whether the delay is caused by an unpaid invoice, a slow client or a cash flow miscalculation.
Map your actual cash cycle
Start by identifying how many days sit between each payday and the date client payments typically clear your account. Use actual bank records, not contract terms. A 30-day payment term often becomes 45 or 50 days in practice.
Include every step: invoice prepared, invoice sent, client approves, payment instructed, funds clear. Add processing time for your own payroll and super payment system. The total number of days is the gap you need to fund.
This is not profit. It is a timing difference that must be carried as working capital while the cash cycle completes. Treat it as a permanent requirement, not a one-off problem to solve this month.
Practical steps to reduce the gap
Invoice promptly. Every day you delay sending an invoice adds a day to the gap. If the work was completed on Friday, the invoice should be prepared and sent by Monday.
Review your payment terms with major clients. A shift from 60 days to 45, or from 45 to 30, materially reduces the working capital you need to carry. Not every client will agree, but the conversation is worth having.
Consider progress billing where the contract allows it. Monthly progress claims on longer projects bring cash in while the work continues, instead of waiting until completion. This compresses the gap between labour cost and cash receipt.
Check your contract terms. Some construction contracts include provision for earlier payment of wages-related costs or allow you to invoice labour separately from materials. If those terms exist, use them.
Adjust pricing to reflect the carrying cost
If you cannot shorten payment terms, the cost of funding the gap should be reflected in what you charge. This is not a penalty to the client; it is a recognition that your business carries the client's labour and super costs for 60 or 90 days before payment arrives.
Work out the actual cost. Calculate the cumulative super and wages you will have paid out by the time the invoice is due, then add the opportunity cost or financing cost of holding that money. Build that figure into your quote as a cost of doing business on extended terms.
Be prepared to explain it. Clients who insist on long payment terms sometimes resist pricing that reflects the cost. If the conversation becomes difficult, you have a clearer picture of whether the work is worth taking.
If the gap is already causing trouble
If upcoming super payments cannot be met from available funds, seek advice now. Waiting does not improve the position, and it increases the risk of penalties and director exposure.
Speak to your accountant or registered tax agent about your current obligations and what options are available. Payment arrangements may be possible, but they are not automatic and they do not remove the underlying timing problem.
If the issue is structural, caused by payment terms that will always create a funding gap larger than your working capital, then the problem needs a structural answer. That might mean renegotiating terms, changing your billing model, securing working capital support or deciding which clients and jobs you can afford to take on.
