There is a common misconception that post-sale relationships cost too much for businesses to fully invest in them. However, this is not true and post-sale relationships are actually vital to any business’s success. In this article, we discuss all of the advantages of fostering post-sale relationships and how you can build post-sale relationships so that they become your greatest growth levers.
The Advantages of Fostering Post-Sale Relationships
Cost Efficiency
Fostering post-sale relationships will ultimately lower your operational costs. Customer retention actually costs less than customer acquisition, meaning it costs less to keep customers coming back than it does to gain new ones. In fact, some studies estimate that acquiring new customers costs at least five times what it costs to retain customers.
Even though customer acquisition is an important part of any business model, it is much more important to maintain customer retention through post-sale relationships and consistent product quality.
Upselling and Cross-Selling
Customer retention has also been proven to lead to more upselling (upgrading current purchases) and cross-selling (adding additional complementary items to original purchases).
Return customers are already satisfied with their past purchases, and that satisfaction leads them to trust your brand. Naturally, increased brand trust leads to more purchases in terms of both upselling and cross-selling.
Regularly interacting with and supporting your customers also leads to major insights into how their wants and needs are shifting over time. You can use these interactions to develop solutions to customer issues or find unique gaps in what you currently offer. This feedback loop will not only help build stronger relationships with your clients but lead to further upselling and cross-selling.
Word-of-Mouth Marketing
Fostering post-sale relationships leads to customer retention, which means that you have loyal customers that will naturally advocate for your business. Word-of-mouth marketing is an incredibly effective way to grow your brand, especially when you’re too small for broad paid advertising campaigns.
Word-of-mouth marketing also creates a network of loyal customers that drive up retention rates, creating exponential growth when paired with high customer satisfaction rates. Instead of trying mainly or solely to appeal to new customers, your main focus should be on creating these networks of loyal customers so that you have the revenue to stabilize and advertise more broadly.
Churn and Customer Lifetime Value
Fostering customer relationships leads to lower churn and better customer lifetime value (CLTV). Customers tend to leave brands when they feel that they are not being properly supported or understood by the brand, and fostering post-sale relationships significantly improves metrics related to churn.
Post-sale relationships have also been shown to improve the overall value that a customer brings to a brand over the entire lifetime of the business. CLTV is a more complicated metric, but this essentially means that loyal customers who feel supported are more likely to bring monetary value to a value business over time.
Net Revenue Retention
Fostering post-sale relationships also leads to improved net revenue retention, which is the percentage of recurring revenue that is retained from your existing customer base. Net revenue retention is driven by reducing churn and improving upselling and cross-selling, which are all results of fostering post-sale relationships.
To put it simply, fostering post-sale relationships not only do not cost more, but they improve revenue streams in your existing customer base across the board. For example, maintaining post-sale relationships help you understand your customer base and thus segment them so that you can better market to certain parts of your base.
How To Build Post-Sale Relationships
Customer Feedback
Asking for customer feedback shows the customer that you care about their thoughts and feelings about how the business is currently run. Customer feedback can also take several different forms, including post-purchase surveys and one-on-one conversations with sales support staff.
Creating a feedback loop will help your business continuously improve your products and services while also helping expand what already is working. For example, a sweets company might test out new batches of chocolate and give free samples to loyal customers to get thoughtful feedback while also engaging with customers.
Encourage Referrals
Set up referral programs so that happy customers are encouraged to recommend your products and services to their friends, family, and colleagues. You can even set up an official rewards-style system where customers that successfully refer receive some kind of major discount and/or free items.
Encouraging referrals creates a network of satisfied customers that will also help improve customer retention rates. As previously mentioned, this kind of word-of-mouth marketing is vital, especially when businesses cannot or do not want to use paid advertising models.
Reward Loyal Customers
Create some kind of rewards system so that loyal customers feel properly acknowledged and appreciated. This can be as simple as offering discounts or free items for when customers make a certain number of purchases or purchase a certain quantity of product.
A formal rewards program can also be established depending on your business size to create a company culture around customer rewards. This will naturally look different based on the specific products and/or services that your business offers. For example, a woodworking tool manufacturer might offer clients who have purchased fiber lasers a lower quote on future cabinet making tools.
Key Takeaways
Despite common misconceptions, fostering post-sale relationships is cost-efficient, improves upselling and cross-selling, improves churn and customer lifetime value, improves net revenue retention, and leads to word-of-mouth marketing. The most effective ways to build post-sale relationships are through customer feedback, encouraging referrals, and rewarding loyal customers. Post-sale relationships are not only not a cost center but can easily be one of your greatest growth levers if you foster them properly.
