A customer asks for a better price. A competitor launches a sale. Your team suggests a promotion to bring in more orders during a quiet month.
Offering a discount can feel like a straightforward way to increase sales. However, the effect on profit is often much larger than the percentage taken off the price.
Before agreeing to a price reduction, it helps to understand how discounting affects profit, how much extra work you would need to sell and whether your business can deliver that work economically.
For New Zealand small business owners, this means looking beyond the number of orders a promotion might generate. The useful question is how the offer changes the financial result compared with keeping your usual prices.
Why a small discount can make a big difference
A discount reduces your selling price, but it does not automatically reduce the cost of delivering the product or service.
Consider an illustrative product that sells for $100 and costs $70 to supply. All figures in this example exclude GST. Each sale generates $30 of gross profit, giving a gross margin of 30%.
A 10% discount brings the selling price down to $90. If the supply cost remains $70, gross profit falls to $20 per sale and gross margin becomes approximately 22.2%.
You have reduced the price by 10%, but gross profit per sale has fallen by one-third.
That leaves less from each sale to cover overheads and contribute to net profit. The effect can be particularly important when your existing margin is already narrow.
Calculate how many extra sales you would need
Using the same example, 100 sales at the usual price produce $3,000 of gross profit. At the discounted price, you would need 150 sales to generate that same $3,000.
That is a 50% increase in sales volume to maintain gross profit, assuming the cost per unit stays unchanged.
The calculation is:
Required sales volume = Original total gross profit ÷ Gross profit per discounted sale.
In this case, $3,000 ÷ $20 = 150 sales.
This does not account for extra advertising, overtime, delivery support or other additional costs. If the promotion creates those expenses, matching the original gross profit will not be enough to preserve your original net profit.
The calculation also assumes all 150 sales receive the discounted price. A targeted offer available to only some customers needs a forecast that separates discounted sales from full-price sales.
Decide what the discount is meant to achieve
Start with a specific purpose. Are you clearing stock, filling unused capacity, encouraging larger orders or attracting customers who may buy again?
Different goals need different measures. A stock clearance may be worthwhile because it releases cash and storage space. An introductory offer might be assessed partly on the later purchases it generates.
Write down the expected benefit, the cost you are willing to accept and the period you will use to assess results. Avoid relying on repeat business that you have no evidence customers will provide.
Business.govt.nz notes that customers attracted by a lower introductory price may leave when the offer ends. Include that possibility when considering whether the promotion makes financial sense.
Check your capacity before chasing more volume
More orders can change the cost of doing business. Your team may handle a modest increase within existing capacity, but a larger increase might require overtime, temporary staff or additional equipment.
For a service business, check how many extra appointments or projects fit into the available hours. Consider travel, administration and follow-up time as well as delivery time.
For a product business, look at stock availability, freight and fulfilment costs. A supplier discount might improve the numbers, while urgent replenishment could make them worse.
Build these changes into the forecast. A promotion that looks attractive using average costs may produce a weaker result once the extra workload crosses a capacity limit.
Protect sales you would have made anyway
Some promotional purchases may come from customers who were already planning to buy at your usual price. Others may simply bring next month’s purchases forward.
Both effects matter when evaluating the result. A busy promotional week does not necessarily mean the business has gained the same amount of additional demand.
Compare the offer with a realistic estimate of sales without it. Review the weeks after the promotion too, particularly where customers can stock up or delay their next order.
For established customers, consider what the offer rewards. A discount linked to a larger order may produce a different result from reducing every customer’s price regardless of buying behaviour.
Consider alternatives to reducing your standard price
An alternative offer may meet the customer’s needs at a lower cost to your business.
For example, a service business could offer a smaller scope at a lower total fee. A retailer could create a bundle with complementary items. A business with unused appointment slots could test an offer limited to those times.
Calculate the cost of any added benefit. Free delivery, extra support and bonus services still use resources, even when their cost is less obvious than a price reduction.
Use the customer’s priorities to guide the offer. Someone asking for a discount may actually need a lower total commitment, a different delivery schedule or clearer evidence of the value provided.
Set clear limits and responsibilities
Decide which products, services and customers qualify, how long the offer will run and who can approve exceptions.
Give your team a simple process for checking the financial effect before agreeing to a larger reduction. Record the agreed price and scope clearly so delivery staff understand what has been sold.
Check whether other benefits apply at the same time. A discount combined with free freight, a referral credit or additional service time may cost more than the team intended.
After the offer, compare expected and actual sales, delivery costs and promotional spending. Record what changed so your next pricing decision starts with better information.
Review the profit result before repeating the offer
A useful promotion should be assessed against its purpose and its full financial effect. Look at gross profit, additional operating costs and cash requirements alongside revenue.
If the goal was customer acquisition, measure whether those customers return and what their later purchases contribute. If the goal was clearing stock, check how much cash was released and what remained unsold.
