Repeat Customer

A repeat customer is a buyer who has made at least two purchases from a store, in contrast to a first-time or one-time buyer. Repeat customer rate — the share of orders or revenue attributable to returning buyers — is a core ecommerce health metric.

What it means

Key insight

Most ecommerce stores earn their actual margin on the second and third purchase — the first is often barely profitable after acquisition costs.

First-time customers are typically acquired at a cost that compresses or eliminates margin on their initial order. The repeat customer is where ecommerce profitability materializes: acquisition cost is zero, average order value tends to be higher as customers become more confident in the brand, and support costs per customer decrease because repeat buyers understand the brand's processes. Repeat customer rate is therefore a direct measure of how well a brand converts one-time buyers into an ongoing relationship. Support plays a specific and underappreciated role here: the most common inflection point between a first and second purchase is the first order's experience — including receiving it on time, having any issues addressed quickly, and feeling positive about the brand after the transaction. A customer who had a small problem but got it resolved instantly is primed to buy again. A customer who had a small problem and waited three days for a response is likely not.

Why it matters

Industry data consistently shows that the top 20% of customers — largely composed of repeat buyers — generate 80% of revenue for many ecommerce brands. Growing the repeat customer base is therefore the highest-leverage growth strategy for a store that already has product-market fit. Support quality is one of three primary drivers of repeat purchase (alongside product satisfaction and competitive price), making it a non-negotiable investment at any stage of growth.
