What it means
Winning a new customer is usually more expensive than selling more to someone who already trusts you. Cross-selling takes advantage of that trust by suggesting related items, such as a bank offering travel insurance to a customer who has just opened a current account.
The offer works best when it solves a real need. The approach depends on knowing the customer.
Companies analyse purchase history, behaviour and life events to recommend what is likely to be useful, whether that is accessories for a new phone or a savings account for a customer who has taken out a mortgage. Relevant offers feel like service, while irrelevant ones feel like pressure.
Cross-selling is different from upselling, which encourages a customer to buy a more expensive version of the same product. A customer who buys a laptop and is offered a case is being cross-sold, while one offered a higher-specification laptop is being upsold.
Many companies use both. Financial measures include the number of products per customer, revenue per customer and customer lifetime value (the total profit expected from a customer over the relationship).
Higher figures usually mean stronger loyalty, because customers with several products find it harder to leave. There are risks.
Aggressive targets can push staff to sell products customers do not need, which damages trust and can lead to regulatory trouble, particularly in financial services. The healthiest programmes reward good advice rather than sheer sales volume.
Measuring results properly means comparing the extra revenue and margin against the cost of the campaign and any discounts offered. That comparison stops a seemingly successful programme from quietly losing money.
In practice
Real-world examples.
Example
A bank manager notices that a customer has just taken out a mortgage and offers home insurance and a savings plan. The customer accepts the insurance because it fits a real need. Because the offer is timely and relevant, the customer does not feel pushed, and the bank deepens the relationship.
Example
An online electronics store suggests a protective case and a charger when a customer adds a phone to the basket. About one in six customers add an accessory, increasing the average order value. The store tests the wording of the suggestion and finds that "customers also bought" outperforms a generic discount banner.
Example
A software company selling accounting tools to small businesses offers payroll as an add-on at renewal. Customers who adopt both products are less likely to cancel because switching would be more disruptive. The company tracks renewal rates for single-product and two-product customers and finds a clear gap in loyalty.
Formula
Calculation
Net cross-sell gain = (Customers x Take-up rate x Price x Margin) - Campaign cost
Worked example: a bank offers a $120 annual insurance product to 5,000 existing customers. The take-up rate is 8% and the profit margin on the product is 50%. The campaign costs $10,000.
Customers who buy = 5,000 x 8% = 400.
Revenue = 400 x $120 = $48,000.
Profit from sales = $48,000 x 50% = $24,000.
Net gain = $24,000 - $10,000 = $14,000.
If the margin were measured on revenue alone, the campaign would look like it earned $38,000 ($48,000 - $10,000), which overstates the benefit.Case study
Seen in the real world.
Riverbend Insurance is a fictional insurer, and this case is illustrative only. Most of its customers held only a single motor policy, and the marketing director wanted to increase the average number of products per customer.
The team analysed which customers were likely to need home cover, based on recent address changes, and sent them a personalised offer with a modest discount. Around 6% of those contacted bought a home policy within three months.
Management tracked the lifetime value of customers with two policies and found they stayed longer. The director cautioned that sales staff should not be rewarded purely for the number of policies, and the scheme was adjusted to reward customer satisfaction as well. The scheme became a model for other product lines, because it combined data, relevance and a healthy respect for the customer.
Watch out
Common mistakes.
- Offering products unrelated to the customer's needs, which feels like pressure and can damage trust. A good test is whether you would recommend the product to a friend in the same position.
- Counting revenue without margin, which can make a campaign look profitable when it is not. Deduct the cost of discounts, commissions and marketing to find the true profit from the programme.
- Setting aggressive sales targets that encourage staff to sell unsuitable products. Incentives that reward suitability and customer outcomes lead to better long-term results.
Questions
People also ask.
What is the difference between cross-selling and upselling?
Cross-selling offers a different but related product, while upselling offers a more expensive version of the same one. Both are valid strategies, and many businesses use them together.
Why do companies prefer it to finding new customers?
Selling to existing customers is usually cheaper because trust and data are already in place. Existing customers also tend to respond better because they already know the brand.
How do you measure success?
Track the take-up rate, products per customer, revenue and margin per customer, and retention against the cost of the campaign.
