Your Sales Price Hasn't Changed - But the Economics of the Job Have
Rising diesel, freight, labour and input costs can quietly turn yesterday's profitable work into today's margin problem.
Written by: Melissa Cunliffe (CA)
There is a dangerous comfort in a familiar sales price. A customer agrees to the same rate you charged last year. The job looks like work you have done dozens of times. The invoice goes out. The customer pays. On the surface, nothing has changed.
But underneath the selling price, almost everything may have changed.
Diesel, freight, fertiliser, chemicals, materials, wages, superannuation, insurance, finance and subcontractor rates can move independently of the price you charge. If those costs rise and the selling price does not, the business absorbs the difference.
Recent Australian reporting has made that particularly visible in farming and transport. ABC News reported in September 2026 that crude oil had moved above US$105 a barrel, the diesel refining margin had risen sharply, and Australia remained highly exposed because it imports most of its diesel. One grain producer estimated the combined effect of diesel, fertiliser and pesticide increases was cutting around 40% from profitability in his operation.
The trap: revenue looks normal
This is why margin pressure is so easy to miss. Revenue does not need to fall for the economics of a business to deteriorate. The same $10,000 job can still be a $10,000 sale. What changes is what remains after the job is delivered.
Suppose a transport job is quoted at $8,000. Last year the direct cost was $5,600, leaving $2,400 of gross profit - a 30% gross margin. This year fuel, labour and subcontractor costs push the delivery cost to $6,600. The invoice is still $8,000, but gross profit is now only $1,400. The customer sees the same price. The owner sees the same turnover. The business has lost $1,000 of gross profit on the same job.
Turnover records what you charged. Margin tells you whether the work was worth doing.
Fixed prices create variable risk
The problem becomes more serious when businesses quote months in advance. Builders, civil contractors, freight operators and service businesses can lock in a customer price long before the final labour, fuel or material cost is known.
If the contract gives the business no ability to recover material cost movements, the business is effectively taking a view on future input prices. Sometimes that risk is understood and priced. Often it is not.
Price-takers have a different problem
Farmers and commodity businesses cannot necessarily solve the problem by simply adding 8% to the selling price. They may sell into markets where the price is largely determined elsewhere. In those businesses, margin management shifts toward yield, procurement, timing, machinery utilisation, financing, labour efficiency and knowing the break-even price per tonne, hectare, head or litre.
The commercial discipline is the same: understand the unit economics before the annual accounts tell you what happened.
Re-cost the job, not just the budget
Many businesses update an annual budget but leave their quoting assumptions untouched. That is backwards. If the business makes money one job at a time, the assumptions inside the quote need to reflect current costs.
Fuel cost per kilometre, machine hour or delivery
Current labour cost including super, leave, overtime and on-costs
Materials and supplier price movements
Subcontractor rates and availability
Freight and travel
Finance or equipment cost where relevant
Expected wastage, rework and downtime
The gross margin the business needs after all of those costs
A surcharge is not always the answer
Fuel surcharges can be useful where they are transparent, contractually supported and tied to a genuine underlying cost movement. But repeatedly adding surcharges can also confuse customers and hide the fact that the base price itself is no longer commercially realistic.
For many businesses the better question is not "Can we add a surcharge?" but "What should this product or service actually cost now?"
Do not confuse a busy business with a healthy business
A margin squeeze often produces exactly the wrong management response: chase more sales. But if every new job is earning less than expected, additional volume can consume more working capital and create more pressure.
Before pushing for growth, compare actual gross margin by customer, job type, product and location. The issue may not be lack of demand. It may be that yesterday's pricing is being applied to today's cost base.
The 4P's lens
People - Rising costs create pressure on owners and staff long before they appear in year-end accounts. Give people clarity about what is changing and why.
Preserve - Protect the margin already being earned by understanding current costs and stopping silent leakage.
Protect - Review fixed-price commitments, quote validity periods, escalation clauses and concentration in volatile inputs.
Prosper - Growth should create more profit and cash - not simply more activity at yesterday's economics.
The Sales Price Question to Ask Before the Next Quote
If we delivered this exact job tomorrow using today's costs, what would we actually make?
That question is far more useful than assuming the job is profitable because it was profitable last year. Prices do not need to move dramatically for economics to change. Sometimes the first warning is not lower sales. It is doing the same work, for the same customer, at the same price - and quietly keeping less of it.
Are your current prices still producing the margin your business needs?
Reviewing your costs regularly can help you identify margin pressure before it affects your bottom line.
