An analysis performed by Bain & Company found that effective cross-selling techniques alone increased revenue from customers who bought additional products by 65% or more. How cross-selling works is by offering products that are similar or complementary to what customers have already purchased.
 Upselling is another technique that retailers can use to increase revenue and customer retention. For many customers, the differences in product pricing aren’t reflected in the products themselves. That means they won’t buy the product that might be what they actually need simply because they don’t know why they need it.
 Both upselling and cross-selling aren’t about using cheap tactics to sell more product -- the benefit is for the customer as well. A study by Ove C. Hansemark and Marie Albinsson found that customer satisfaction drives customer retention.
 If you can better meet your customer’s needs by upselling and cross-selling, you will increase revenue -- guaranteed.

Cross-sell to the right customers at the right times.

In the early 1990’s, Sears began a cross-selling strategy in the financial services industry by offering credit cards to customers. This boosted their retail sales and garnered them 6.4 million credit card holders in 1996 alone.
 On a smaller scale, cross-selling can still be extremely effective. Here are some examples of cross-selling that you and your staff can use to boost sales:
Use cross-selling sparingly and meaningfully. Since the benefit is to your customer, you don’t want to overwhelm them with deals and bundles and offers. Instead, you are responding to the customer’s needs, whether or not they perceive them.

Upsell for your customer’s best interest.

Upselling is about educating the customer about their options and why the items are distinctively priced. The perception of the customer is the focus of upselling, and the relation of quality to cost.
 When a customer walks into your retail store, they may not know that you have exactly what they need. They might be prepared to pay any price for what they need, but because they think a shirt is a shirt is a shirt, they will buy whatever hits their fancy first.
 Upselling, then, is informing your customers how higher value items could benefit them. Here are some tips for your floor staff to increase sales from upselling:
Another way to properly upsell is to offer savings on the extra cost items. Say that you have a product that has features, such as a desktop computer that can have a larger HDD for a premium price. If your customer explains they need a lot of storage space for digital media, you can upsell them by offering a discount on the upgraded desktop.
 In the example above, the customer’s need was identified after they talked about their experience. This particular customer may not need help visualizing the value of more storage space -- that’s what they’re looking for after all.
 To improve your upselling and cross-selling efforts, also try using POS software that makes the task easier. Erply’s POS software includes a Suggested Sales feature, for example, making cross-selling that much smoother.
 

In the Erply back-end, I can assign a bracelet as a cross-sell product for the item “silver necklace”

  

When the silver necklace is entered at the register, “bracelet” automatically comes up as a cross-sell prompt.

  If you’re looking to boost sales and increase customer satisfaction and retention, use proper upselling and cross-selling techniques. You will see the difference, and your customers will appreciate your efforts.
