A small discount can create a large sales target

A discount reduces the contribution from each sale, so the extra volume needed to protect profit can be much larger than the discount percentage.

A customer asks for ten per cent off. The sales team sees a small concession and a quick way to close. The owner should ask a different question: how much contribution disappears, and how much additional business is needed to replace it? A discount applies to the selling price, while many delivery costs remain unchanged.

The answer depends on the starting economics. A ten per cent price reduction does not necessarily mean a ten per cent reduction in what the business keeps. Calculate the difference before deciding whether the commercial benefit is worth it.

Put the original offer beside the revised one

Use a fictional product selling for ₦10,000 with ₦6,000 of variable cost per item. Before other costs, contribution is ₦4,000. A ten per cent discount reduces the selling price to ₦9,000. If the variable cost stays at ₦6,000, contribution falls to ₦3,000.

The price fell by ten per cent, but contribution per item fell by 25 per cent. Both statements are correct because they compare the change with different starting figures. Keeping the terms clear prevents a modest sounding concession from hiding a significant economic change.

Now assume the business would otherwise sell 100 units. Original total contribution is ₦400,000. At the discounted contribution of ₦3,000 per unit, the business needs approximately 133.34 units to match that amount. Where only whole units can be sold, it needs at least 134 units.

Check whether the additional volume is possible

The arithmetic does not establish that customers will buy 34 more units. It does not establish that the team can deliver them, that enough stock is available or that collections will arrive on time. Those are separate assumptions that deserve evidence.

Ask where the additional demand will come from. Is the discount reaching new customers, encouraging an earlier purchase or simply charging existing buyers less for an order they would have placed anyway? The last outcome can reduce contribution without creating a compensating benefit.

Then inspect capacity. Extra sales can trigger overtime, additional transport, packaging changes or a temporary hire. If variable costs rise at the new volume, the original calculation understates the required sales. A promotion can also displace full price work when the business is already busy.

Include the costs of the promotion

Advertising, special materials and extra delivery arrangements are not free because they sit outside the product cost. Add the relevant promotion costs to the contribution target. If the campaign costs ₦30,000 in the fictional example, matching the original ₦400,000 after that cost requires ₦430,000 of contribution before the campaign expense.

Keep the comparison honest. Do not subtract normal fixed costs from one option and omit them from the other. Do not count revenue as profit. Do not claim a campaign succeeded merely because the sales line increased.

A promotion earns its place by changing customer behaviour enough to justify what the business gives away.

Consider what the customer actually needs

A lower price may be the right commercial choice, but it is not the only way to improve an offer. A customer may value a clearer delivery date, a useful bundle, a smaller initial quantity, a better payment arrangement or reduced uncertainty. Each alternative has a cost and should be evaluated rather than treated as a clever free substitute.

A quantity condition can make a concession more explicit. A limited scope can protect service delivery. A time limited offer can support a genuine campaign decision. Avoid invented scarcity or confusing conditions that damage trust after the sale.

For services, a price reduction paired with unchanged scope may leave the team carrying the same work for less contribution. Discuss the outcome, included work and responsibility before agreeing. Reducing a fee and hoping delivery somehow becomes cheaper is not a plan.

Run a controlled comparison

Define the purpose before the promotion begins. Record the normal price, expected baseline volume, discounted economics, campaign costs and required additional sales. Choose a review date. Track actual contribution and relevant customer behaviour, not only the number of enquiries.

Use a comparable period with care. Seasonality, stock availability and a different customer mix can affect the result. A small experiment may provide a useful signal without proving a universal rule. Record what remains uncertain rather than turning a favourable week into a permanent pricing policy.

What is the discount supposed to achieve?

Define the reason before approving the concession. Clearing an obsolete item, encouraging a larger order and responding to a competitor are different decisions. Each should have a limit and a result to observe. A discount offered simply because the customer asked can become a permanent habit without anyone checking whether it helps the business. The sales team needs a clear purpose for the concession and a way to know when that purpose has been achieved.

Check whether the additional order would have happened anyway. If a customer was already prepared to buy at the normal price, the discount may reduce contribution without creating useful additional demand. It may still be a deliberate relationship decision, but that is a different justification. Keep the explanation visible. A business cannot learn from promotions if every concession is described afterwards as necessary to win the sale, regardless of what the evidence actually shows.

Which costs change when volume rises?

The simple contribution calculation assumes that the cost of each additional unit stays consistent. In practice, extra volume can trigger overtime, express delivery, temporary labour or a new storage requirement. It can also create purchasing advantages if they are genuinely available. Confirm those effects rather than assuming that every larger order is more efficient. A discount that looks manageable at ordinary unit cost may become unattractive when delivery has to be rushed.

Capacity deserves a separate check. If the business is already constrained, a discounted order may displace another order that would have produced stronger contribution. The relevant comparison then includes the alternative use of the scarce time or resource. This does not require a complicated model for every quotation. It does require a clear question: what other work will this commitment prevent or delay, and is that trade worth making under the actual operating conditions?

How should discount authority work?

Give staff a practical approval boundary that reflects contribution and the type of concession. A small percentage may have a large effect on a low contribution offer. A larger percentage may be affordable where the cost structure is different. Avoid one universal rule that ignores those economics. The person granting a concession should understand the realised price, the included work and any change in payment terms before promising the customer an exception.

After the order is delivered, check whether the expected benefit appeared. Review volume, contribution, collection and any unusual service burden. If a promotion produced enquiries but little profitable trading, record that honestly. If it helped clear a genuine stock problem, explain that result on its own terms. The decision should leave a lesson that can guide the next concession. Otherwise a series of apparently small discounts can quietly rewrite the business model without a deliberate pricing decision.

Before approving the next concession, ask the person proposing it to write down the extra profitable sales it must create. Then ask who will deliver those sales and what evidence makes the assumption believable.
