Inflation does not affect all businesses equally

Inflation is often described as a rising tide that lifts all prices. In reality, it acts more like a filter. Some small and medium-sized enterprises find their margins squeezed and their cash flow strained. Others quietly increase prices, expand revenue and improve profitability.

Australia’s recent inflation cycle has demonstrated this divergence clearly. While insolvency numbers have risen in sectors like construction and discretionary retail, other industries, including certain services, repair trades and essential goods providers, have maintained or even expanded margins. The difference is rarely luck. It usually comes down to pricing power, cost structure, demand resilience and financial management.

Inflation is not just a macroeconomic statistic. It changes behaviour. It reshapes consumer priorities. It alters financing costs. And it exposes weaknesses in business models that were previously hidden by stable pricing environments.

The historical pattern: inflation rewards certain traits

History shows that inflationary periods tend to reward businesses with three core characteristics:

• Pricing power

• Strong cash flow discipline

• Asset or demand resilience

During the 1970s oil shock era, businesses that could pass on higher input costs without losing customers survived more easily. In contrast, firms locked into fixed-price contracts or with weak brand differentiation struggled.

More recently, during the post-COVID inflation surge between 2021 and 2023, many SMEs with subscription models or essential service offerings managed to adjust pricing in line with rising costs. Businesses dependent on fixed-margin supply contracts often saw profitability collapse.

The lesson is structural. Inflation magnifies whatever strengths or weaknesses already exist within a business model.

Pricing power is the single biggest differentiator

Pricing power is often misunderstood. It does not mean charging more because costs rise. It means customers are willing to absorb price increases without significantly reducing demand.

SMEs that tend to perform better in inflationary environments often operate in categories where:

• The product or service is essential

• The cost represents a small percentage of the customer’s total budget

• The brand or relationship reduces substitution risk

• Alternatives are limited or inconvenient

Examples include certain maintenance trades, healthcare services, specialised B2B providers, accounting and compliance services, and niche suppliers embedded in client operations.

By contrast, highly commoditised retail products with minimal differentiation struggle to pass on costs, particularly when consumers are already under household budget pressure.

In inflationary cycles, the question becomes simple but difficult: can you raise prices without materially reducing volume?

Cost structure matters more than revenue growth

Revenue can rise during inflation simply because prices rise. That does not guarantee improved profitability.

SMEs that thrive during inflation typically share one of two cost advantages:

1. High fixed costs, low variable costs

2. Asset-light operating models

In the first case, once fixed costs are covered, incremental revenue carries strong margins. If prices rise faster than wage or input costs, margins expand.

In the second case, businesses with minimal inventory exposure, limited capital equipment and flexible labour models avoid some of the input cost volatility that hits asset-heavy operators.

Construction firms with fixed-price contracts and rising materials costs illustrate the opposite dynamic. When inputs rise faster than revenue adjustments, margins compress rapidly.

Inflation rewards businesses that can either reprice quickly or operate without heavy exposure to volatile inputs.

Working capital becomes a competitive advantage

Inflation does not only raise prices. It increases the cost of holding inventory and financing receivables.

Businesses that manage working capital tightly often outperform because they:

• Turn inventory quickly

• Collect receivables faster

• Negotiate favourable supplier terms

• Avoid overstocking

During inflation, holding excess inventory can become expensive if financed with debt. At the same time, certain businesses strategically benefit from holding stock purchased at lower pre-inflation prices, which can later be sold at higher market prices.

The distinction lies in control. Businesses that intentionally manage inventory cycles outperform those reacting passively to cost changes.

Cash flow timing becomes more important than profit reporting during inflationary phases.

Interest rates change the playing field

Inflation often brings tighter monetary policy. In Australia, the Reserve Bank has used rate increases to curb demand and slow price growth. Higher interest rates affect SMEs unevenly.

Businesses with:

• Fixed-rate debt secured before rate rises

• Strong cash reserves

• Low leverage

May find themselves at an advantage relative to competitors refinancing at higher rates.

Conversely, highly leveraged SMEs with variable-rate debt face margin compression as interest expenses rise.

Inflation is therefore intertwined with capital structure. The businesses that thrive are often those that entered the inflation cycle with conservative balance sheets.

Which sectors tend to outperform in inflationary periods?

Historical and recent data suggest several SME categories tend to show relative resilience or strength:

Essential services
Maintenance trades, healthcare providers and compliance services often retain demand regardless of economic cycles.

Repair and refurbishment businesses
When consumers delay major purchases due to higher living costs, repair services often see increased demand.

Commodity-linked operators
Businesses tied to sectors benefiting from global commodity price rises may see revenue tailwinds.

Subscription-based businesses
Predictable recurring revenue allows gradual price adjustments.

Discount or value-focused retailers
As consumers trade down, lower-cost alternatives gain market share.

By contrast, luxury discretionary retail, fixed-margin contracting and heavily leveraged construction firms often face greater stress.

Inflation reshuffles demand patterns rather than uniformly shrinking them.

Consumer psychology shifts before spending data does

One under appreciated feature of inflationary environments is behavioural change. Rising grocery and fuel prices affect consumer confidence quickly. Households adjust spending priorities before official data fully reflects the shift.

SMEs that monitor customer behaviour closely and adjust product mix, pricing tiers or service offerings early often adapt more successfully than those waiting for formal indicators.

Inflation is partly economic and partly psychological. Perceived financial pressure can influence purchasing patterns even when incomes are rising.

The businesses that struggle

Understanding who struggles clarifies who thrives. SMEs tend to face difficulty in inflationary cycles when they:

• Operate in commoditised markets with thin margins

• Cannot reprice quickly due to contracts

• Carry high variable input costs

• Hold excessive inventory financed by debt

• Rely heavily on discretionary consumer spending

Inflation does not create these weaknesses. It exposes them.

How SMEs can position themselves more effectively

Thriving in inflation is less about reacting to CPI prints and more about strategic positioning. Practical actions often include:

• Reviewing pricing strategy regularly rather than annually

• Analysing contribution margins by product or service line

• Improving receivables collection processes

• Negotiating supplier contracts proactively

• Stress-testing cash flow under higher interest assumptions

• Reducing low-margin offerings

Importantly, communication matters. Transparent, well-explained price increases tend to be accepted more readily than sudden unexplained adjustments.

Inflation rewards proactive management over passive observation.

Is inflation always negative for small business?

Not necessarily. Inflation increases nominal revenue across the economy. Businesses that manage cost escalation effectively can grow profit in absolute terms, even if real purchasing power declines elsewhere.

Inflation also increases replacement costs for assets, which can strengthen the relative value of businesses that already own property, equipment or inventory acquired at lower historical prices.

The key variable is adaptability. Businesses that treat inflation as a static threat often struggle. Those that treat it as a dynamic environment adjust faster.

The broader lesson

Inflation is not evenly distributed. It transfers purchasing power, alters competitive dynamics and reshapes cost structures. Some SMEs contract under the pressure. Others quietly expand.

The difference usually comes down to pricing power, working capital control, cost flexibility and balance sheet strength.

Inflation does not guarantee success or failure. It amplifies whatever fundamentals already exist within a business.

For Australian SMEs navigating the current cycle, the question is not whether inflation is good or bad. It is whether your business model is built to adapt when prices move.

That distinction determines who survives and who thrives.
