Why busy restaurants still struggle with cash flow in summer

Josh McNicol, Director of Growth at Zeller, on managing peak season cash flow.

As the industry moves out of the summer trading period, many operators are now assessing what peak season actually delivered financially. The common assumption is that busy periods automatically translate into healthier finances, but this is increasingly out of step with the reality of running a busy hospitality venue.

Research from Zeller showed that more than 1 in 4 hospitality business owners have recently considered shutting their doors, the second highest closure forecast rate of any sector. That statistic highlights a growing disparity between customer demand and financial sustainability of many venues. Understanding why that disconnect occurs is becoming critical for hospitality operators trying to navigate an environment of higher wages, elevated supplier costs, and persistently thin margins.

Why Summer concentrates financial risk 

The holiday trading season compresses a large share of annual trade into a short window. Zeller’s own payments data (analysed from nearly 100,000 businesses transacting with Zeller Terminal nationally) from the most recent Summer trading period shows that in some tourism hotspots, 20 per cent of total annual transaction volume occurs in Summer. In destinations such as Maroochydore in Queensland, that figure rises to as much as 36 per cent of the total annual transaction volume. 

While this concentration of demand is a major opportunity for restaurateurs to capitalise on increased foot traffic, it also creates significant financial pressure. A short period of intense trading requires operators to over-invest in employees, stock and operating capacity before the benefits of that demand are fully realised.

The result is a paradox many restaurant owners recognise; dining rooms are full and bookings are strong, yet the bank account balance can still feel tight.

The cost surge before revenue 

Preparing for peak trading means spending well before the rush actually begins. Restaurants typically increase staff rostering, extend trading hours, and place larger orders with suppliers in anticipation of increased demand. Labour costs are often the first pressure point. Additional shifts, weekend penalty rates, and casual staff brought in to manage booking surges can quickly push wage bills higher. 

At the same time, kitchens must increase orders of food, drinks and other supplies to avoid running out during busier service periods, meaning more cash tied up in inventory. These costs land immediately, while the financial benefit of strong trade can take longer to stabilise the bank balance.

More customers doesn’t always mean higher revenue

Higher customer volumes also don’t necessarily translate into higher spending. Zeller’s transaction data indicates that while transaction volume increases during Summer, the average value of each transaction changes very little.

In practical terms, this means restaurants may serve more customers without seeing a meaningful increase in the average spend per diner. Combined with rising operating costs, that dynamic can leave venues working harder while margins remain under pressure.

The operational realities of running a restaurant

Restaurants also face operational pressures that can make cash flow particularly difficult to manage. Demand can shift quickly due to weather, tourism flows, public holidays or major events, requiring operators to adjust staffing and stock levels with short notice. 

Kitchens must also manage highly perishable inventory. Food that is not sold within a short timeframe becomes waste, making stock planning both essential and risky. Many venues also deal with multiple suppliers, each with different payment terms, while still needing to ensure wages and operating costs are covered week to week. 

These realities mean restaurant operators are constantly balancing the risk of under-preparing for demand with the financial strain of committing too much cash to staff and inventory.

How experienced operators are responding

Investing in smarter financial technology that guides venues on cash flow and sales trends, enabling them to analyse historic trading patterns and better forecast, can support in making more informed decisions about staffing and stock levels, and identify pressure points sooner. 

Supplier relationships are also really important, specifically clear communication around payment schedules and delivery timing. This can help operators align outgoing payments more closely with incoming revenue. In fact, Zeller’s own invoicing data shows that digital invoices sent as soon as the job is complete with immediate (same day) payment terms are paid fastest; on average, within 3.73 days. 

More broadly, many hospitality businesses are beginning to treat cash flow as a daily operational metric rather than something only reviewed at the end of the month.

Final thoughts

Strong summer trade remains essential for the viability of Australia’s restaurant sector. Busy services provide the revenue that many venues rely on to sustain operations throughout the year. However, the financial health of a restaurant is no longer down to how many customers it serves. The timing of costs and payments has become just as important as the volume of bookings. In an environment of higher costs and tighter margins, peak trading periods can expose weaknesses in cash flow management rather than solve them. 

Therefore, it’s important for venues to understand that profitability is shaped not only by demand, but by how effectively they manage the flow of money through their business.
