Revenue Backlog

Revenue backlog, often simply called backlog, represents the total value of contracted, non-cancellable future revenue that has not yet been recognized. It is comprised of firm orders and signed agreements for products or services to be delivered at a future date. Backlog is distinct from a sales pipeline, which contains potential deals that are not yet closed and confirmed.

A growing backlog indicates strong market demand and provides visibility into future performance, making it a critical metric for financial forecasting and revenue planning. It helps companies manage resources, plan capacity, and communicate expected growth to investors and stakeholders. For subscription-based businesses, backlog often includes the total contract value (TCV) for all signed agreements, portions of which will be recognized as revenue over the contract term.

While related, backlog is not the same as deferred revenue. Backlog includes the full value of all future contracted revenue, regardless of whether it has been billed or paid for, whereas deferred revenue specifically represents cash that has been collected from a customer for services not yet rendered.
