# B2B SaaS marketing audit: published findings and scope

Separate pipeline attribution, closed won acquisition, billing and retention. Pipeline value is not collected revenue; acquisition and expansion require their own cohort and cost periods.

The 8 published B2B SaaS case highlights sum to $480k in annual figures, with a lower median of $52k. Each case explains its own outcome; the sum does not establish realized cash recovery.

## What the B2B SaaS figures mean

8 published B2B SaaS cases: **$52,000 lower median annual highlight figure**. The [estimator](/estimator/saas/) uses a separate $60k model reference. Equal figures in some sectors do not make these the same statistic.

The population is the 74 published case studies, with one selected highlight figure per case. It is not a representative sample of all SMBs or a total of every finding in each audit. A lower median is the middle value after sorting, using the lower of the two middle values for an even count. Published annual figures include different outcome types; they are not all collected cash, profit or recurring savings. Case publication dates do not establish common observation, implementation or recovery periods; use each case for its supported timing and outcome.

Separate pipeline attribution, closed won acquisition, billing and retention. Pipeline value is not collected revenue; acquisition and expansion require their own cohort and cost periods.

## Where B2B SaaS budgets leak

In the 8 published B2B SaaS audits, acquisition holds the most cases and pricing holds the largest one. 4 cases, $219k a year in case figures, come from channels scored on something other than revenue: brand term search and retargeting claiming deals that would have closed anyway, a low intent channel that filled the funnel and slowed the sales cycle behind it, content with no path to an opportunity, and an ad budget whose placements and dayparting were never optimized after launch.

The two pricing and billing cases are worth $162k a year between them. The larger, $92k a year and found in 7 days, is late quarter discounting that compounded every quarter; the other is a usage rule that never billed overages above plan limits. Cost to serve adds 2 more: free tier support that cost more than the plan earned, and partner fees paid on deals the direct team had sourced.

None of these shows up in a pipeline report, because pipeline counts opportunities, not collected revenue. Every audit below follows spend through to closed won revenue, billing and retention before it calls a channel efficient.

Three patterns across the 8 published B2B SaaS cases. Each card names the cases it rests on; open one for its evidence. The five patterns behind them are defined in [the margin leak guide](/margin-leaks/).

Acquisition

### Spend scored on leads, not revenue

Channels rewarded for cheap leads, impressions or content output are rarely checked against closed won revenue. Scored that way, the cheapest leads can turn out to be the most expensive customers, and some paid spend buys demand sales already owned.

4 of the 8 published cases · $36k to $74k a year

- [Paid was subsidizing a channel sales already owned](/cases/paid-was-subsidising-a-channel-sales-already-owned/), $41k a year

Pricing and billing

### Discounts and billing gaps eroding contract value

Late quarter discounting and billing settings that never charge usage overages give away revenue the contract already earned.

- [A billing config gap left usage overages uncharged](/cases/a-billing-config-gap-left-usage-overages-uncharged/), +$70k a year

Cost to serve

### Support and partner fees nobody reconciled

Free tier support that costs more than the plan earns, and partner referral fees paid on deals sales sourced directly, sit outside the marketing budget and are rarely reconciled against it.

- [Free tier support cost more than the plan earned](/cases/free-tier-support-cost-more-than-the-plan-earned/), +$52k a year
