Discounting to Drive Sales?
The Costs and Benefits for UK Businesses
If sales have slowed, stock is sitting on shelves, or you are trying to attract new customers, discounting can look like an obvious answer. Drop the price. Create some urgency. Get more people buying.
Sometimes, that is exactly the right move. Other times, it could cost you a lot more than you perceive.
Use discounts and sales strategically. A promotion should have a clear purpose, a defined margin and a realistic view of its impact on your cash flow.
Before you reduce your prices, be clear about what you want to achieve.
Understand what the discount will cost your business. Then consider whether there is a better way to drive sales without cutting into your profit.
When Can Discounting Help Your Business?
Discounting has a place when you use it with a specific goal, clear time limits, and a strict plan to protect your profit margins.
Discounting can:
- Solve specific sales or stock problems.
- Encourage first-time buyers.
- Incentivise up- and cross-sales.
- Reward loyalty.
- Boost short-term sales.
The key is knowing what you want the promotion to achieve before you set the discount.
1. Clearing Slow-Moving Stock
If cash is tied up in stock that is not selling, a targeted discount can help release it.
This can be particularly useful for seasonal products, older inventory, or items being replaced by a new range. Taking a smaller margin on stock that is unlikely to sell at full price may make commercial sense if it frees up cash and warehouse space.
That does not mean discounting everything that is moving slowly. First, establish why the stock is not selling. If the problem is poor demand, an unsuitable product, or weak marketing, simply cutting the price may not solve it.
2. Attracting New Customers
A first-order discount can entice potential customers to try your business.
What happens afterwards is crucial. Work out what a new customer is worth to your business before deciding how much you can afford to spend acquiring them.
If someone buys once at 20% off and never returns, you have effectively paid to acquire a single sale. If they become a regular customer who keeps buying at your normal price, the initial discount is much easier to justify. This is called Customer Lifetime Value (CLV).
3. Managing Seasonal Demand
Some businesses experience predictable peaks and troughs in demand. A well-timed promotion can help generate activity during a quieter period.
However, be careful not to call every increase in sales a success.
If customers simply bring forward purchases they would have made anyway, you have changed the timing of revenue rather than increased it. That may still be useful for cash flow, but you should understand the difference when assessing the promotion.
The Hidden Costs of Discounting
The most obvious cost of a discount is the reduction in selling price. The bigger issue is what that reduction does to your margin.
Suppose you sell a product for £100, with a cost of £70. Your gross profit is £30.
A 10% discount takes the selling price down to £90. Your cost is still £70, so your gross profit falls to £20.
You reduced the price by 10%, but your gross profit fell by 33%.
That means you need considerably more sales to generate the same gross profit as before.
That gap widens as the discount increases. If your margins are already tight, a promotion that looks modest to the customer can substantially affect your profitability.
Discounting Can Also Increase Your Costs
Discounting can encourage more orders, but more orders usually mean more work.
Ask yourself what it costs you to fulfil those extra orders, especially if there is a rapid influx.
A discount campaign can inadvertently place more pressure on your business.
You may need additional stock, packaging, delivery capacity, temporary staff, overtime, or marketing spend to handle the increase.
You need to know what it will cost to generate and fulfil the additional sales, not just how much revenue the promotion could bring in.
Your Customers May Start Waiting for the Next Sale
Frequent discounts can change buying behaviour.
If customers regularly see 15% or 20% discounts, they may become less willing to pay the standard price. Instead, they wait for the next offer.
This is especially noticeable in e-commerce.
A customer may add items to their basket, leave without buying, and then wait for an abandoned-cart email offering a discount.
If you regularly respond with 10% or 15% off, customers can learn that leaving their basket is a way to get a lower price.
Over time, that can make your standard price harder to maintain, particularly if your business relies on premium pricing or has built its reputation around quality rather than low prices.
There is a difference between using a discount for a specific commercial reason and teaching customers that waiting, asking, or abandoning a purchase will eventually result in a better price.
How to Discount Without Killing Profit
If you decide to run a promotion, start with the numbers rather than the percentage you think will attract attention.
Calculate your margin at your normal price, then model what happens at different discount levels.
For example, a 10% discount may be manageable, while 20% could take your margin below a level you can sustain. You also need to account for any additional costs the promotion generates.
Then decide what success looks like.
- If the objective is to clear stock, measure how much inventory was released and how much cash it generated.
- If you are trying to acquire customers, track whether they come back and what they spend afterwards.
- If you are trying to increase sales during a quiet period, compare the additional gross profit with the cost of running the promotion.
You should also set a limit before the promotion begins. Decide how long it will run, which products or services are included, and the maximum discount you are prepared to offer.
That gives you something to measure against, rather than letting the promotion continue simply because sales are increasing.
Should You Discount Everything?
Probably not.
A blanket discount can be an expensive way to create urgency when a more targeted promotion would achieve the same result.
You could discount specific overstocked products rather than your whole range. You could offer an incentive on larger orders or limit the offer to customers who are genuinely new to your business.
Personalising discounts to a specific audience segment can also create a sense of exclusivity. This is a powerful tool if you offer memberships or tiered loyalty programmes.
Some products do not need discounting at all.
If a product is already selling well, reducing its price could mean giving away margin you would otherwise have earned.
The same applies to services. If you have limited capacity, filling every available slot with discounted work may leave you busier without making the business more profitable.
Alternatives to Discounting
If your objective is to increase sales, reducing your price is not your only option.
A bundle can encourage a larger purchase without applying the same discount to every item. A retailer, for example, might combine complementary products at a price that feels attractive while protecting the margin on the individual items.
You can also add value rather than remove price. Depending on your business, that could mean free delivery, additional support, an upgrade, or an extra service.
Another option is to create a minimum order value for an incentive. This can increase the value of each transaction rather than simply reducing the price of an existing purchase.
These approaches will not suit every business, but they are worth considering before you automatically reach for a percentage-off promotion.
Think About Cash Flow Before You Launch
A successful promotion can require more cash than you expect.
If you sell more, you may need to buy more stock before those sales generate cash.
You may need to increase your marketing budget, pay suppliers sooner, or cover additional operating costs.
Consider timing, too. Imagine you run a promotion in September, but your customers have 30- or 60-day payment terms. You may have to fund the stock and fulfilment costs well before the cash from those sales reaches your bank account. You want to avoid creating working capital pressure, even with a profitable promotion.
Before committing to a major campaign, map out the expected cash coming in and going out. Consider the best-case scenario, but also what happens if sales are slower than expected or customers take longer to pay.
Could Funding Support a Planned Promotion?
If you have decided that discounting is commercially worthwhile, the next question is whether your existing working capital can support the strategy.
You may have the margins and the demand but not want to commit a large amount of your available cash to one sales initiative.
Using funding can give you more room to act while keeping cash available for the rest of the business.
The key distinction is that funding should support a sound strategy, not compensate for one that doesn’t work financially.
At Funding Alternative, we look at the wider commercial picture when assessing funding requirements. If a planned promotion is part of a wider growth or stock strategy, we can help you consider how additional working capital could fit alongside your existing commitments and cash flow.
Plan the Promotion, Then Protect the Business Behind It
The best promotions are not simply about getting more people to buy.
They generate sales that make commercial sense for your business.
Know what you are trying to achieve, understand what the discount does to your margin, and make sure you can fund the activity required to deliver the extra sales.
And where a good sales opportunity is being held back by working capital, it is worth looking at the funding position alongside the promotion rather than treating them as separate decisions.
