Singlepurchase

Singlepurchase is a term used in e-commerce analytics and data modeling to denote a transaction categorized as a one-time purchase event. In many data schemas it is represented by a binary flag attached to an order or a customer record, indicating that the purchase is not part of a subscription, recurring plan, or bundle purchase.

The exact definition of singlepurchase varies by organization. Some implementations classify a singlepurchase as an order containing exactly one line item; others treat it as any purchase by a customer who does not enter a recurring arrangement within a reporting window. Because definitions differ, the metric is typically described alongside its criteria and limitations.

Purpose and uses of singlepurchase include segmenting customers into one-time buyers, evaluating the effectiveness of marketing channels for first-time purchases, and measuring revenue that is not expected to recur within a given period. It can be compared with non-singlepurchase segments to inform short-term revenue projections and initial customer acquisition analyses. Analysts may track changes in the singlepurchase rate over time and relate it to campaigns or product changes.

Practical considerations involve ensuring consistent criteria and documenting the taxonomy used, since misclassification can occur with multi-item orders or complex billing arrangements. The metric is most useful when paired with related measures such as first_purchase, repeat_purchase, churn, and average order value to provide a fuller view of customer behavior.
