How Investing In The Post-Sale Relationship Has Helped Our Business Stay On Top For 40 Years
Many businesses focus on everything that leads to a successful sale, but nurturing post-sale relationships will bring true success. Satisfied, loyal customers are far more valuable to a business than brand-new ones because they buy more and bring other customers with them. In fact, several estimates claim that the cost of customer acquisition is up to five times higher than customer retention. In this article, we explain why investing in post-sale relationships will help your business achieve success that lasts decades.
The Benefits of Building Post-Sale Relationships
Higher Customer Retention Rates
Customers who have had a positive affinity for your brand and have experienced high-quality support are significantly more likely to continue purchasing products and services. Transactional relationships that end with the sale are too short-term and leave money on the table.
Not investing in post-sale relationships will lead to higher customer churn. Customer retention rates also compound over time, meaning that a customer’s value will increase and multiply alongside all of the other customers that they help draw in.
Increased Upselling and Cross-Selling
Loyal customers are also more likely to buy more of a product and a wider range of products. New customers will naturally trust your business less, making it harder to convince them to buy more of a product or even to make a purchase at all. Strong post-sale relationships will create customers that are much more friendly to both upselling and cross-selling.
Satisfied customers with no reason to leave will want more of what they purchased, and they will also trust the quality of your brand enough to try other products that they were not sure about on the first pass. Over time, customers who are properly cared for see vendors as trusted partners with whom they have formed a human relationship.
Better Customer Lifetime Value
Customer lifetime value (CLV) is a key success metric that represents the total revenue a customer generates throughout their relationship with your business. Investing in post-sale support extends the relationship, increases purchase frequency, and gradually raises the average transaction value over time.
Customers who trust you are more likely to buy from you more often, upgrade more readily, and be less sensitive to price increases. Multiplying those effects results in a high-value customer, and that type of customer will give referrals, which can then be nurtured to provide more value.
Automatic Word-of-Mouth Marketing
Investing in post-sale relationships also automatically drives word-of-mouth marketing. Happy, loyal customers are likely to recommend your business to their friends, family, and colleagues. This type of marketing costs you nothing and yet brings better conversion rates than most paid advertising, because they are more effective at knowing what their friends, family, and colleagues are looking for when making their recommendations.
Word-of-mouth marketing also does not need to be forced. Instead, it should be a natural byproduct of ensuring that customers are happy with your product and receiving high-quality customer service. With some incentive for referrals, satisfied customers will build a network of advocates who are all doing high-quality word-of-mouth marketing that most other businesses wish they could pay for.
Better Customer Feedback
Customers who have been properly invested in post-sale also tend to give much better quality feedback. Customer feedback is one of the easiest ways to know how your business is performing and which areas need the most improvement or expansion.
Satisfied, loyal customers will provide more in-depth feedback that goes beyond whether or not they are happy with your products and services. They can flag any potential problems early so that you can take quick action, and they also can point you toward new product opportunities. Investing in post-sale relationships creates a feedback loop that guarantees your products and services are always improving and staying competitive.
Improved Customer Database
Retaining customers and creating strong post-sale relationships with them also leads to a stronger and fuller customer database. Every meaningful post-sale interaction will enrich your understanding of who exactly your customers are and what they want. Continuous surveys will slowly accumulate customer profiles with increasing accuracy.
An in-depth and well-maintained customer database will help you provide more targeted marketing, better personalize your customer service, and limit the amount of time you waste guessing at customer reasoning. Put simply, improving your customer database will help your business bring more value to your customers, which then increases and improves the customer base you already have.
How To Build Post-Sale Relationships
Feedback
Customer feedback is one of the most basic ways to make customers feel seen and heard. Start with a personal check-in within 72 hours of purchase to make sure that the product and/or service was the quality that the customer expected.
Follow up with your customers at certain lengths of time (e.g., after 30 days, after 90 days) in order to create regular opportunities for customers to share their experience. Having full conversations or even just sending short, personalized emails will help build an actual post-sale relationship more than a basic form survey will.
Once you’ve gotten thoughtful feedback from customers, you need to acknowledge it and show that you’ve taken action. For example, a coffee and tea business could ask customers for feedback on their seasonal menu and add the most popular drink to their current menu year-round. Customers who see that their feedback has been taken seriously are more likely to become invested in your business and its future success.
Referrals
Encouraging referrals will also help establish post-sale relationships and build an entire supportive network. Some business owners might try to establish a referral relationship immediately after the sale is complete, but demonstrating value to the customer will cause more and better referrals.
Try to make referral requests at opportune times, such as after a particularly positive check-in or once you’ve taken action on a piece of customer feedback. You could even incentivize referrals by offering certain discounts once conversion is successful. For example, a business that purchased a CNC router could get a discount for future woodworking tools if they successfully refer another business to buy a CNC router or equivalent product.
Customers who refer someone to your business have extended their own credibility and reputation, so you should also make sure to personally thank any customer who refers your business to others.
Personalization
Personalizing your business model, especially your customer service, will also deepen your relationship with your customers. Keep track of any personal preferences for your customers, try to remember past conversations, and record any special details that apply to your business. Referencing past preferences and other details when interacting with repeat customers makes them feel valued and increases your brand reputation with them.
Train your staff to also take on as many of these personalization tasks as possible so that every part of your business is making customers feel seen, heard, and appreciated. Personalizing your business model will improve customer retention rates, increase customer loyalty, and drive referrals.
Knowledge Bases
Knowledge bases improve post-sale relationships by helping customers get the most out of their purchases. Knowledge bases can also take many different forms, including FAQs, detailed how-to guides, tutorials, and troubleshooting resources for any common customer issues. The exact form and content of your business’s knowledge base will depend on what you sell and what your customers need to know to properly use your products or services.
Customers who feel fully equipped and supported are going to be more satisfied and loyal to your business. Quality knowledge bases also reduce the strain on your support staff, freeing them to focus on providing personalized, high-quality customer service unrelated to certain common customer issues.
Knowledge bases can also be boosted with AI chatbots and other automation so that customers get quick responses and solutions that do not require human intervention. Customers that want support outside of regular customer service hours can consult both knowledge bases and AI features to quickly resolve their issue.
Loyalty Programs
Loyalty programs are one of the most classic ways to invest in post-sale relationships because they reward customers for exactly what you want them to be doing. For example, a CNC shop rewards program might involve a returning laser buyer receiving a loyalty discount on their next machine purchase.
Loyalty programs can also vary widely in form based on your exact business, but the basic premise remains: encouraging customers to refer other customers, repeat purchases, and remain engaged for the sake of a clear reward.
Make sure that you design a loyalty program that brings actual value to the customer, for a poorly designed program can just as easily frustrate a customer and increase churn rates. Ask frequently about customer satisfaction around your loyalty program during feedback sessions to ensure that your loyalty program, like any part of your business, is always improving.
Key Takeaways
Business owners may well be tempted to focus on high conversion rates, but investing in post-sale relationships is the smarter financial move. The benefits of building post-sale relationships include higher customer retention rates, increased upselling and cross-selling, better customer lifetime value, automatic word-of-mouth marketing, better customer feedback, and improved customer databases.
Any business owner can invest in their own post-sale relationships by embracing customer feedback, encouraging referrals, personalizing their business model, creating knowledge bases, and establishing loyalty programs. Businesses that want to become legacies and last for multiple decades need to keep their customers satisfied and appreciated long after the first purchase.
