In the ever-evolving landscape of e-commerce, customer retention has become a focal point for retailers striving to build lasting relationships. It goes beyond the transaction — it’s about creating an engaging customer journey that extends well beyond checkout. In this blog post, we explore why post-purchase engagement is one of the most overlooked growth levers, and how Avarda stands out by giving merchants full ownership of communication after the purchase.

The Significance of Customer Retention

Customer acquisition is critical, but retaining customers is where long-term profitability is won. Research from Harvard Business Review and Bain & Company shows that acquiring a new customer can be 5–25 times more expensive than retaining an existing one.

Even small improvements have large impact. Bain & Company also found that increasing customer retention by just 5% can boost profits by 25–95%.

Loyal customers also behave differently:

According to analyses based on the book Marketing Metrics, companies have a 60–70% chance of selling to an existing customer, compared with only 5–20% for new prospects.

Additional research summarised by customer loyalty studies shows that repeat customers buy more frequently and spend more over time. Retention isn’t just a metric, it’s a commercial engine.

The Journey Does Not End at Checkout

While many merchants focus on delivering an efficient checkout, the customer journey shouldn’t end with the final button click. This is where Avarda differentiates in the payment solution landscape. We empower merchants to own the entire customer journey — including the post-purchase communication that most payment providers control.

A standout feature of Avarda’s solution is the ability for merchants to communicate directly with customers on the invoice and throughout the purchase-to-payment flow.

Why does this matter?

Research from email performance studies shows that transactional messages such as invoices and order confirmations, have open rates of 40–70%, compared to 15–25% for traditional marketing emails.

This makes the invoice one of the most powerful and underutilized touchpoints in the customer journey — and Avarda gives it back to the merchant.

Research compiled in loyalty behaviour studies shows that existing customers are 50% more likely to try new products and spend significantly more than new customers.

Customer Engagement & Loyalty

When customers hear from you after checkout, not just before, you foster trust and repeat behaviour — essential drivers of lifetime value.

Customer retention is not just a buzzword — it’s a strategic imperative. With research consistently showing the financial impact of retention, it’s clear that post-purchase engagement is a channel no retailer can afford to ignore.

Avarda’s unique approach to empowering merchants with full control of post-purchase communication — especially on the invoice — transforms a high-engagement transactional touchpoint into a powerful driver of loyalty, upsell, and long-term customer value.
