Growth and pipeline benchmarks: backlog, book-to-bill and win rate

At a mid-size IT consulting firm, the CFO's Monday morning report shows $340 million in signed-but-undelivered contracts. That single number, called backlog, lets her forecast next quarter's revenue within a few percentage points, before a single new deal closes. This is how finance teams inside professional services firms actually plan: not by guessing, but by reading pipelinepipelineAll active sales opportunities across the stages of the sales process, together with their combined potential value and probability of closing.View full definition → metrics that translate sales activity into a revenue timeline.
Why pipelinepipelineAll active sales opportunities across the stages of the sales process, together with their combined potential value and probability of closing.View full definition → metrics matter more here than in other sectors
Professional services firms (consulting, IT services, legal, engineering, accounting) sell labor and expertise, not inventory. Revenue is recognized as work gets delivered, not when a contract is signed. That creates a lag between "sold" and "earned."
Three metrics bridge that gap:
Backlog: the dollar value of signed contracts not yet delivered (i.e., not yet recognized as revenue).
Book-to-bill ratio: new bookings divided by revenue billed in the same period.
Win rate: the percentage of proposals or bids that convert into signed contracts.
Together they answer the question every services CFO asks: "What does our revenue look like six to twelve months from now, based on what's already in hand?"
Backlog: your revenue runway
Definition: Backlog (also called "book of business" or, in government contracting, "contract backlog") is the total value of signed, awarded work not yet delivered or invoiced.
Backlog matters because professional services revenue is lumpy and project-based. A firm can have a fantastic quarter of new sales and still miss its revenue target if delivery capacity or timing doesn't line up. Backlog tells you how much revenue is already contractually locked in, waiting to be earned.
Worked example:
A management consulting firm starts Q1 with $200 million in backlog. During the quarter it signs $90 million in new contracts and delivers (recognizes as revenue) $110 million of existing work.
If average project duration is about 9 months, that $180 million gives management a rough revenue runway of roughly two to three quarters, assuming no further bookings, which is a useful stress-test scenario.
Benchmarks (estimates, as of 2025 fiscal year reporting):
Large IT services and government contractors often disclose backlog explicitly. US federal contractors like Leidos and Booz Allen Hamilton typically report backlog-to-revenue ratios in the range of 2.5x to 4x annual revenue, reflecting multi-year government contracts (Booz Allen investor relations publishes this each quarter).
Pure consulting firms (McKinsey, BCG, Bain) are private and don't disclose backlog publicly, so backlog discipline there is an internal management tool rather than a market signal.
European engineering and IT services firms (e.g., Capgemini, Atos) report an "order book" metric that is functionally similar to backlog, often expressed as months of revenue coverage; Capgemini has historically targeted order book coverage of roughly 12 months of forward revenue (estimate, based on company disclosures).
Book-to-bill ratio: are you selling faster than you're delivering?
Definition: Book-to-bill ratio = New bookings (signed contract value) ÷ Revenue billed (recognized) in the same period.
Ratio above 1.0: bookings are outpacing delivery. Backlog is growing. Good leading indicator of future growth.
Ratio below 1.0: the firm is delivering faster than it's selling. Backlog is shrinking. Warning sign if sustained over multiple quarters.
Ratio near 1.0: steady state, growth is flat.
Worked example:
Using the numbers above: new bookings of $90 million ÷ revenue billed of $110 million = 0.82 book-to-bill.
That's a caution signal. This firm sold less than it delivered this quarter. One quarter isn't a crisis, but three consecutive quarters below 1.0 should trigger a hard look at the sales pipelinesales pipelineAll active sales opportunities across the stages of the sales process, together with their combined potential value and probability of closing.View full definition →.
Benchmarks (estimates):
Healthy growth-mode professional services firms typically target book-to-bill ratios of 1.1 to 1.3 over a trailing twelve months.

Staffing and IT services firms in the US (e.g., Accenture, in its quarterly bookings disclosures) report bookings alongside revenue precisely so investors can compute an implied book-to-bill; Accenture's new bookings have often run at roughly 1.0 to 1.2 times revenue in recent fiscal years (estimate, based on public quarterly disclosures, subject to change each reporting period).

Definition: Win rate = Contracts won ÷ Total proposals or bids submitted, over a given period. Sometimes measured by count of deals, sometimes weighted by dollar value; always check which basis is used before comparing firms.
Worked example:
A boutique strategy consultancy submits 40 proposals in a year and wins 10.
Win rate = 10 ÷ 40 = 25%
Whether that's good depends heavily on segment:
Benchmarks (estimates, industry-reported ranges):
Management consulting (competitive RFPs, request for proposals): win rates commonly cited in the 20% to 35% range for competitive, multi-bidder pitches.
Relationship-driven or sole-source engagements (repeat client, incumbent advantage): win rates often exceed 60%, sometimes cited as high as 70 to 80% for incumbents renewing existing scopes.
Legal services (RFP-based panel reviews, common among large corporate clients in the US and UK): win rates in the 15% to 30% range are typical for new-client competitive panels, per industry surveys such as those referenced by the Association of Corporate Counsel.
Government contracting: win rates on new (non-incumbent) bids are frequently lower, often cited around 10% to 20%, because of formal, heavily scored, multi-bidder procurement processes.
A rising win rate combined with a rising book-to-bill ratio is the strongest combined signal of healthy forward growth. A rising win rate with a falling book-to-bill can simply mean fewer, smaller deals are being pursued.

Putting the three together: a mini forecast
Here's how a finance team actually chains these metrics into a forecast, in simplified form:
That 0.83 ratio, projected forward, tells the CFO that unless win rate improves or bid volume increases, backlog and future revenue will keep contracting. This is the exact kind of forward-looking arithmetic finance teams run before board meetings, and it's far more actionable than looking at last quarter's revenue alone.

Key Takeaways
Backlog is signed, undelivered contract value: it's your revenue runway. Rising backlog signals future growth; shrinking backlog signals a coming slowdown even if current revenue looks fine.
Book-to-bill ratio (new bookings ÷ revenue billed) above 1.0 means the pipelinepipelineAll active sales opportunities across the stages of the sales process, together with their combined potential value and probability of closing.View full definition → is outpacing delivery, growth is coming. Below 1.0 for multiple quarters is an early warning sign.
Win rate (deals won ÷ deals bid) varies enormously by segment: 20-35% is typical for competitive consulting RFPs, 60%+ for incumbent renewals, and often under 20% in government contracting.
All three benchmarks are estimates that shift by sub-sector, geography and economic cycle; always check whether figures are trailing-twelve-month or single-quarter, and whether they're dollar-weighted or count-based, before comparing across firms.
The real power is in combining them: backlog tells you what's locked in, book-to-bill tells you the trend, and win rate tells you why.
