The pre-Christmas cash squeeze is the most predictable financial event in Australian small business, and it still ambushes thousands of owners every year for one reason: it hides behind a great P&L. December posts the year's best revenue, everyone celebrates, and the celebration obscures what's already in motion — the season's costs were paid in cash before and during, while a chunk of its revenue arrives (or doesn't) into January's hole, just as the summer's deferred obligations land. The squeeze isn't bad luck; it's a shape. Here's the mechanics and the November moves that flatten it.
The shape of the squeeze
Walk the cash through the quarter. November–December, money goes out early: stock and materials bought ahead of the season (cash now, revenue later), the loaded Christmas roster (penalties and casual hours paid weekly, in real time), and for project businesses, work-in-progress racing toward pre-Christmas completion — costs incurred, invoices not yet out or not yet due. Late December, the inflow engine stalls: B2B customers shut down with their accounts teams, so invoices issued mid-December routinely sit until late January; retail's December cash is real but stops abruptly. January, the hole: trading thins or stops, while the fixed costs — rent, salaries for permanents, leases, subscriptions — march on without noticing the season. Then February, the cluster: the December-quarter BAS due 28 February (carrying the GST on your biggest revenue quarter), often a PAYG instalment with it, the post-holiday supplier statements, and any annual costs that renew with the calendar year. Add payday super running through every December pay event (the old "quarterly super due 28 January" cliff is gone, but its replacement is that the season's loaded payrolls each carried their super in real time — the cost arrived earlier, not later).
Profit-wise, the quarter looks fine. Cash-wise, it's a valley with a tax bill at the bottom — and businesses that don't model it discover their year's low-water mark in the same week the ATO's direct debit lands.
The November moves
Everything that fixes February happens before December. In order of leverage:
Model the valley explicitly. Run the 13-week forecast from mid-November through early March with the season's real shape: the loaded payrolls in their actual weeks, the stock payments, honest January receipts (look at last year's — when did December's invoices actually clear?), the February BAS estimated from the December quarter you're forecasting. The output is one number: the lowest projected balance and its date. Everything else is managing to that number.
Drag December's invoices forward. Invoice the instant work completes — a December 10 invoice has a fighting chance of clearing before shutdown; a December 22 invoice is February money. For project work, get progress claims to whatever stage you can before clients' accounts teams leave; for the big customers, the early-December call ("anything you need from us to get this into the last payment run of the year?") is the highest-ROI collections activity of the season.
Pre-fund the BAS as you trade. The February BAS feels brutal because it's the GST on your best quarter, spent by the time it's due. The fix is the buffer habit: a fixed percentage of takings swept weekly to a separate tax account, all season. The money was never yours; the sweep just makes the accounting emotional truth.
Right-size the season's commitments. Stock orders against forecast rather than optimism (dead January stock is the squeeze wearing inventory's costume), the trade-or-close decision made per public holiday on real arithmetic, and discretionary spending — the new ute, the office refresh — scheduled for March, after the valley, not December, before it.
Arrange the buffer from strength. If the modelled low point is uncomfortable, November is when the overdraft conversation happens — banks price a forward-planning customer very differently from a February emergency. Likewise the ATO: if the BAS will genuinely strain, a payment plan arranged proactively is routine; one requested after default is a relationship repair.
The squeeze, properly handled, becomes almost dull: the valley was forecast, the buffer was funded, the invoices went early, and February's obligations debit an account that was built for them. That's the whole trick — December's job is revenue; November's job is making sure February survives it.
FAQ
How much should the tax buffer sweep be?
Enough to cover GST net of credits plus PAYG withholding as they accrue — your accountant can set the percentage from your actual ratios; many businesses land somewhere in the teens of gross takings. Start it now even if late; a partial buffer beats none.
We're retail — December cash is huge. Same problem?
Inverted timing, same valley: your cash peak is December, your trough is still late January–February after the season's suppliers and the BAS. The error retail makes is reading the December balance as the new normal and spending it; the forecast keeps the peak honest.
What about pausing super or PAYG to get through?
No. Withheld amounts and super are other people's money with personal-liability regimes attached (director penalties cover both) — they're the worst possible financing source. The legitimate tools are the buffer, the facility, the ATO payment plan, and earlier invoicing. They are also, run early, entirely sufficient.
