Many businesses focus their growth strategies around what leads to conversion. The factors that influence whether a customer makes a purchase are still fundamental, but the post-sale relationship is one of the most underappreciated growth levers. Loyal customers stay longer, buy more products, and refer your business to their contacts. In this article, we discuss how to build successful post-sale relationships and the benefits of such post-sale investment.
How to build successful post-sale relationships
Personalize customer service
Personalizing customer service is one of the most straightforward ways to build a successful post-sale relationship. Many larger organizations are opting for AI chatbots and self-service options, but you can stand out through human-focused customer service. Personalization is also a much easier task to pull off for startups and small businesses, so it is a natural strength worth leaning into.
You can personalize your customer service model by training your customer support team to remember past conversations, track personal preferences, and keep in mind specific details so that they can be referenced later. These habits will make both potential and loyal customers feel seen and heard.
Request feedback
Requesting feedback is another way to keep customers engaged, especially if you demonstrate that you have taken action on their concerns or suggestions. You can start with a quick and personalized check-in within a few days of the initial purchase. This can be a full conversation or a short email query.
There should be a set schedule so that you can regularly request customer feedback. Set intervals at 30 days and 90 days, but also send out anonymous customer surveys in case anyone is not comfortable making their complaints directly. Acknowledge any feedback you receive and take visible action on it. Customers are more likely to be loyal if they believe they are helping shape your business.
Create a knowledge base
Although personalized customer service is best, some customers want to solve their own issues without having to talk to anyone. Create a knowledge base that answers all of the most frequent customer questions and also solves the most common issues that they can solve without external help. Implementing this will also free up time and energy that your support staff can spend on more personalized customer service.
The form that your knowledge base takes will depend on the specific products or services that your business offers. More complex products will require more technical expertise and thorough guides for basic operation. No matter what, the objective of your knowledge base should be about your customer getting the fullest value from their purchase.
Reward customer loyalty
Loyal customers also should be rewarded in some way for their continued patronage. This can be as simple as giving a discount or free item to encourage a repeat purchase. For example, a CNC equipment manufacturer could offer their customers a lower rate on woodworking machines if they can show proof of any past purchase.
The type of rewards program you put in place will depend heavily on what your business offers. Free items are not as lucrative when most of your company focuses on long-term services, and referral-based rewards work best when you are trying to get known in a close-knit community. A poorly designed program will frustrate your customers, but one built around genuine customer needs will improve customer loyalty.
Encourage customer referrals
Encouraging customer referrals will help your business build a full network from your post-sale relationships. Demonstrate the value of your product and your business in general and then ask at opportune times for a possible referral. The best time to encourage customer referrals is usually whenever someone expresses great satisfaction or once you’ve acted on feedback.
Customer referrals can also be folded into your rewards program. Offer some kind of incentive (e.g., free items, significant discount, social media shout-out) or make it a structural part of your loyalty scheme. Asking customers to refer their friends and acquaintances has high conversion rates and costs you very little.
The benefits of post-sale investment
Better customer retention
The greatest benefit of investing in post-sale relationships is better customer retention. People who feel satisfied and engaged are more likely to return and make more purchases at your establishment. This increase in customer retention will also naturally improve profitability since loyal customers tend to have more value than new ones.
Customer retention is a factor that compounds in a way that customer acquisition never will. Drawing in and converting new prospective customers should be a focus for any business, but each customer’s value will multiply over time and pull in other customers after them.
Upselling and cross-selling
Investing in post-sale relationships will also improve both upselling and cross-selling because a customer happy with their purchase is also going to be happier with your brand in general. In addition to staying loyal, satisfied customers are also more likely to upgrade their current purchases and/or add additional complementary products to their original purchase.
Implementing knowledge bases and personalizing customer service can also help guide customers to learn more about what they want and need from your business. Your company can also use these interactions to develop custom solutions that only further increase upselling and cross-selling.
Word-of-mouth marketing
An underappreciated benefit of post-sale investment is free word-of-mouth marketing. When you take the time and energy to ensure customers are satisfied and getting the most value from their purchase, you are giving them reasons to recommend your business. Focus less on attracting new customers and focus a bit more on turning repeat customers into brand advocates.
Word-of-mouth marketing will slowly create a network of loyal customers, and this will only further drive up retention rates while getting more value from your base. If you continue to invest in the post-sale relationships with everyone in this network, high customer satisfaction rates will drive exponential growth.
Critical insights
Focusing your business plan almost entirely on conversion rates is a losing game, because investing in post-sale relationships is what will truly ensure long-term success. You can build relationships with your customers through personalization, feedback, knowledge bases, rewards programs, and referrals. If you make these adjustments, your business will see better customer retention rates, more upselling and cross-selling, and free word-of-mouth marketing.
