Justin's Johannesburg signage company has just had its best November ever. The order book is full, the team has earned their year-end bonuses, and three large invoices are due on 15 December. Then the emails arrive: his clients' finance departments have closed for the holidays and will "process payments in January".

By Christmas Eve, Justin has paid early salaries, bonuses and suppliers, and his bank balance is the lowest it's been all year. The next salary run is five weeks away.

December is a cash trap for many South African businesses, whether trade booms or goes quiet. Here's how to plan cash flow for seasonal businesses so the festive season doesn't drain you before the new year begins.

Why December Squeezes Cash Flow for Seasonal Businesses

The festive season hits cash flow in one of two ways, depending on your business.

Peak-season businesses (a Cape Town restaurant, a Garden Route guesthouse, a retail store) see revenue rise, but costs arrive first. Extra stock is bought in October and November, casual staff and overtime are paid weekly, and after New Year trade drops sharply while rent and salaries carry on.

Quiet-season businesses (B2B services, construction, manufacturing suppliers) see clients shut down from mid-December to mid-January. Payments stall, but your costs keep running.

Both face the same calendar pressures: year-end bonuses, salaries often paid before Christmas, and four public holidays (16, 25 and 26 December, plus 1 January) that cut trading and banking days.

Build a Festive Season Cash Flow Forecast

A cash flow forecast lists the money you expect in and out of your bank account, so you can spot shortfalls before they happen. For the festive season, plan week by week from November to the end of February. Monthly totals hide the gap between paying out on 20 December and getting paid on 20 January.

1. Start with your actual bank balance today, not your profit figure.

2. List expected receipts by the week you'll realistically get them, not the invoice due date. Move anything due after about 10 December into January.

3. List every outflow by week: salaries, bonuses, stock, rent, debit orders and SARS payments.

4. Find your lowest point. That's the minimum cash you need to get through the season.

5. Decide now how to cover any gap: delay a purchase, agree longer supplier terms, or arrange an overdraft facility before banks slow down too.

If your bookkeeping is up to date in Xero, Sage or QuickBooks, most of this data is already there. This is exactly where outsourcing to a firm like Saber Accounting pays off: a forecast built from accurate books is one you can actually rely on.

Collect From Debtors Before the Shutdown

Every invoice paid before mid-December is cash you don't have to borrow. Start in November, not December:

• Invoice the moment work is done. Don't batch December invoices to month-end.

• Ask key clients for their last payment run date. Many corporates finalise payments in early to mid-December.

• Chase overdue accounts now, while their finance teams are still at their desks.

• Take deposits on December jobs, especially for once-off or new clients.

• Consider an early-settlement discount only if your margin allows. A 2% discount on a R100 000 invoice costs R2 000, which may still beat overdraft interest over January.

Plan Bonuses, Payroll and SARS Payments

Year-end bonuses are taxed through PAYE in the month you pay them. If you pay bonuses in December, that month's EMP201 (the monthly PAYE, UIF and SDL return) will be higher than usual. It's due by 7 January 2027, when cash is often at its lowest, so budget for it alongside the bonus itself.

If you pay December salaries early, your staff wait five weeks or more for January's pay, and some will ask for an advance. Decide your policy now and communicate it early, so you're not making cash decisions on 23 December.

VAT can catch peak-season businesses out too. Most vendors account for VAT on invoices issued, not cash received. If you're a Category B vendor (two-month periods ending in even months), your November–December return and payment are due by the last business day of January on eFiling, even on sales customers haven't paid for yet. Set aside the VAT and PAYE portion of every December receipt in a separate account.

Prepare for the Long January Cash Flow Dip

January is slow for most South African businesses. Consumers are stretched by school fees and holiday spending, and corporate clients take weeks to restart.

If December is your peak, work out your fixed monthly costs and ring-fence at least two months' worth before treating festive profits as spendable. If it's your quiet season, review debit orders and subscriptions now, and approach suppliers or lenders about payment arrangements before a payment is missed, not after.

Remember that February brings its own pressure. For businesses with a 28 February year-end, the second provisional tax payment is due that same day.

Plan December's Cash Flow in November

December's cash crunch is predictable, which means it's preventable. A weekly forecast, early collections, and a clear plan for bonuses, PAYE and VAT turn the festive season from a scramble into something you manage. For seasonal businesses in South Africa, where clients close for weeks and January drags on, the difference is starting before the rush rather than during it. Put your forecast together now, while you still have time to act on what it shows you.
