NRR (non-recurring revenue): Measure for non-recurring revenue

Non-recurring revenue (NRR) refers to revenue that is one-off and does not occur regularly or repeatedly. Unlike recurring revenue, which is generated through subscriptions or long-term contracts, non-recurring revenue comes from one-off sales or services, such as project work, consultancy services or one-off product sales. Non-recurring revenue is often less stable and predictable than recurring revenue as it is not based on repeated customer contracts.
