Quick answer
You can raise prices safely by first working out how much volume you can lose before profit falls (a 5 per cent rise on a 20 per cent margin tolerates losing about one customer in five), then rising in stages, giving fair written notice, explaining what customers get and protecting your best accounts. Test on new work first, then roll out.
Key points
- Calculate the break-even volume loss first; it's usually far larger than owners fear
- Margin, not turnover, decides how much a price rise helps profit
- Raise on new customers and new quotes first, then existing accounts with written notice
- Check contracts and ACCC pricing rules before you change anything
- A price rise is cash-flow medicine; it works faster than most loans and costs nothing to borrow
Ask a dozen owners why they haven’t raised prices and you’ll hear the same sentence in different words: “I’d lose customers.” Sometimes that’s true. More often it’s a fear measured against nothing, while the cost of staying put is measured in every invoice.
Held prices are a decision too. When wages, rent, insurance and materials move up and prices stay still, margin is the thing that gives way, and margin is what pays the loan repayments, the tax and you. This guide works through how to raise prices with your eyes open: the numbers first, then the sequence, the wording and the cash-flow effect.
How many customers can I lose before a price rise hurts?
This is the question that changes the conversation, and it has a tidy formula. The share of sales you can lose and still make the same gross profit is:
price rise ÷ (gross margin + price rise)
Say your gross margin is 20 per cent and you raise prices by 5 per cent:
5 ÷ (20 + 5) = 20 per cent.
You could lose one sale in five and make the same gross profit, while doing less work, buying less stock and chasing fewer invoices. Lose less than that, and profit climbs.
Here is how the break-even loss shifts with margin, for the same 5 per cent rise:
| Gross margin | Volume you can lose and break even |
|---|---|
| 10% | 33% |
| 20% | 20% |
| 30% | 14% |
| 50% | 9% |
The thinner your margin, the more room a price rise gives you. A cafe or trade supplier on a tight margin has more to gain than a software business on a high one. Work out your own margin with the margin and markup calculator, and see how fixed costs change the picture in break-even analysis for small business.
One caution: the formula uses gross profit, so if your variable costs are higher than you think, run it with the real figure. Your profit and loss statement is the source.
Which customers should I worry about, and which not?
Not all revenue is equal. Before you pick a number, rank accounts by what they really earn after discounts, service time, slow payment and returns.
- High value, low effort: protect these. Raise gently, explain well, keep in touch personally.
- High volume, thin margin: these often look important and earn very little. A larger rise is justified, and losing one may improve the year.
- Low value, high effort: raise, or restructure the offer. Many owners discover a handful of customers consume a third of their time for a tenth of their profit.
- Price-shoppers: they’d leave over a few dollars whatever you did. Don’t plan around them.
The business.gov.au advice on improving cash flow suggests focusing on your most profitable customers, products or services, and testing whether you can raise prices without losing business. That is exactly this exercise.
What’s the safest order to roll out a rise?
Sequence the change, so each step gives you evidence for the next.
- New quotes and new customers first. Nobody sees a “before” price. You learn quickly whether the market accepts the new level.
- Add-ons and extras next. Minimum order fees, callout fees, rush charges and delivery surcharges are easier to introduce than a headline change.
- Existing customers with notice. Write to them, don’t spring it on an invoice.
- Contract renewals. Use the renewal date as the natural moment for the new rate.
If you have an annual rhythm, a small rise on the same date each year (and a note explaining why) is easier for customers than a big jump every five years. Regular, modest moves become part of how you trade.
How do I word the notice?
Keep it short, factual and warm. A good notice does four things: states the new price and the date it starts, gives the reason in a sentence, mentions what hasn’t changed, and offers a way to talk if it creates a problem.
From 1 February, our standard rate moves from $110 to $118 an hour. Wages, vehicle and insurance costs have all risen over the past year, and this keeps us able to turn up on time with the right people. Your service, your account manager and your payment terms stay as they are. If you’d like to talk it through, call me directly.
Notice what’s missing: apologies, long justifications and hints that the decision might be reversible. Over-explaining signals that you don’t believe the number yourself.
What do contracts and rules say?
Before sending anything, check three things:
- Your own agreements. Fixed-price contracts and service agreements may only allow a change on renewal or with a set notice period. Look for a price variation clause.
- How prices are displayed. Consumer prices must be clear and include GST, and the ACCC publishes guidance on pricing practices. Business-to-business is more flexible but should still be transparent.
- Your own terms. If you rely on standard terms that let you change prices, make sure customers have actually received them.
If you’re a small business customer of larger suppliers yourself, note that the unfair contract term protections for small businesses can apply to one-sided clauses in standard form contracts, which may include price variation terms.
Will customers actually leave?
Some will. Most won’t, and the ones who do are often the least profitable. Watch for these patterns:
- Silence is usually acceptance. Many customers simply pay the new invoice.
- A small number push back. Have an answer ready: a modest concession, a longer commitment in exchange for the old rate for three months, or a package that suits them better.
- A few leave. Compare the actual loss against your break-even figure. If it’s under the threshold, the rise worked.
Track three numbers for 90 days: customers lost, average order value and gross margin. That’s your evidence, and it turns the next rise from a gamble into a routine.
A worked example
An illustration, not a real business. A plumbing company in Adelaide has a 25 per cent gross margin on a $900k turnover, so gross profit of $225k. Costs have crept up and its owner wants to lift prices 6 per cent.
Break-even volume loss: 6 ÷ (25 + 6) = about 19 per cent. The business could lose nearly one job in five and not go backwards.
The owner starts with new quotes, then adds a $40 callout fee for after-hours work, then writes to commercial maintenance clients with 30 days’ notice and a short explanation. Two small clients leave, representing about 3 per cent of revenue. The rest stay.
On those assumptions, revenue falls to about $873k from lost clients but rises about 6 per cent on the rest, so the result is roughly $925k, and with lower costs on the lost work, gross profit rises by well over $30k. Real life is messier, but the direction holds.
Can a price rise solve a cash-flow problem?
Often faster than borrowing. A rise lifts every future sale without adding a repayment. It’s also the one lever that improves your margin permanently, so it supports a loan application later: lenders look at stability and margin, and a business that has held its margin through cost increases is easier to assess. See how to cut business costs fast for the other half of the margin equation, and how to fix a cash flow problem fast if timing is the immediate issue.
But sometimes the squeeze is acute: a price rise takes months to flow through, and a BAS, wages or a supplier is due this week. That’s a different problem. A price rise won’t help with this month’s gap, and it’s reasonable to bridge it separately.
When is borrowing the right bridge?
If costs have already outrun your prices and there’s a hole to cover while the new pricing takes effect, short-term funding can bridge the gap, provided the plan to repair margin is real. Borrowing to keep selling at a loss only delays the problem.
If you’re in that position, our enquiry form takes around a minute and doesn’t involve a credit check, so there’s nothing to worry about on your credit file. We don’t send your details out to a crowd of lenders. A real person reviews what you’ve written and rings you. Describe the gap honestly, including what you’re doing about margin, so the option we raise first actually fits.
Frequently asked questions
How much notice should I give customers of a price increase?
Check your contract or terms first, because they may set a notice period. Where nothing is set, 30 days in writing is a common and fair standard for ongoing customers, longer for large accounts. One-off quotes can simply be issued at the new price.
How much can I raise prices without losing customers?
There's no universal figure. Small, regular rises in line with your cost increases are usually accepted. The better question is how much volume you can lose and still make more profit, and the break-even formula answers that.
Do I have to show GST in my prices?
Prices advertised or quoted to consumers must include GST. Business-to-business quotes often show GST separately, but should be clear about it. The ACCC publishes the pricing rules that apply, so check them when you update price lists.
Should I raise prices for existing customers or only new ones?
Usually both, in sequence. New customers and new quotes at the new price is the lowest-risk test. Existing customers then follow, often with a short grace period or a value add for the longest-standing ones.
What if a major customer refuses the increase?
Work out what that customer is actually worth after all costs. Some accounts look large but earn little once discounts, slow payment and service time are counted. You may offer a smaller rise, a volume commitment or shorter payment terms rather than losing the account.
Can a price rise help me get a loan?
Indirectly, yes. Lenders look at margin and the stability of profit. A business that has passed on cost rises and holds its gross margin presents better than one whose margin has been quietly shrinking.
