Backlog

Backlog is the total value of contracted work that has been signed but not yet delivered or recognized as revenue, representing the firm’s funded delivery queue and most reliable leading indicator of near-term revenue. A client has committed, the SOW is executed, and the work is scheduled.

Backlog vs. pipeline

Backlog and pipeline measure different things and should not be combined in a revenue forecast:

• Backlog: signed contracts, committed revenue, work queued for delivery.
• Pipeline: qualified opportunities that have not yet closed.

Backlog is a fact. Pipeline is a probability-weighted forecast. A near-term revenue forecast starts from backlog, then adds expected pipeline conversions on top.

How backlog converts to revenue

As the team delivers against contracted work, backlog burns down and converts to recognized revenue. The rate of conversion is a function of delivery velocity and billing terms. When delivery is ahead of billing milestones, the converting work may sit temporarily as WIP before the invoice is raised.

Remaining backlog = Total contracted value - Revenue recognized to date

Why backlog matters to operations

Backlog drives staffing decisions. If backlog is growing faster than capacity allows delivery, the firm needs to hire or subcontract. If backlog is shrinking without pipeline coverage to replace it, a near-term revenue gap is forming. Resource planning without visibility into backlog is guesswork.

A healthy firm typically carries three to six months of forward backlog. Below two months signals a gap in pipeline conversion or slow revenue recognition. Above nine months may indicate a capacity constraint that is delaying delivery and deferring revenue.

Backlog coverage

Backlog coverage expresses backlog as a multiple of a forward period’s revenue target, typically the next quarter or the next 12 months. A backlog coverage ratio of 1.5x entering a quarter means the firm has 1.5 times its target already under contract before selling anything new. Coverage ratios are used by practice leads and finance to assess how much pipeline conversion is required to hit plan.

Backlog coverage is a lagging indicator of sales activity: a deteriorating coverage ratio usually reflects a slowdown in contract signings weeks or months earlier. Monitoring it alongside pipeline provides an early warning of revenue gaps before they appear in recognized revenue.

Common backlog mistakes

• Including unexecuted proposals or verbal commitments in backlog: those belong in pipeline until a contract is signed.
• Not adjusting backlog when change orders are executed mid-engagement, which overstates or understates remaining commitment.
• Reporting backlog by total contract value without netting out revenue already recognized, which inflates the figure and overstates the funded queue.
• Treating revenue recognition timing as fixed when it depends on billing milestones and delivery velocity, which can make backlog conversion appear slower or faster than it is.
