B2B Agency Pricing Assessment Suite
The Starr Conspiracy's B2B Agency Pricing Assessment Suite gives marketing leaders a personalized pricing model, cost benchmark, and pipeline ROI projection, so you can defend agency spend with confidence and cut evaluation cycles from 11 weeks to under 4.
What This Suite Is and Who It's For
The B2B Agency Pricing Assessment Suite by The Starr Conspiracy is a four-tool toolkit built for B2B marketing executives, demand-gen leaders, and VPs of marketing who have to defend outsourced agency spend to a board or CFO. It produces a personalized pricing model recommendation, a percentile-banded cost benchmark, a pipeline ROI projection, and an engagement structure score. Mid-market B2B tech buyers who run this suite before signing report cutting agency-evaluation cycles from an average of 11 weeks to under 4, based on our 2024 client onboarding data (n=37).
How the Suite Scores and Calculates
Each of the four tools draws on a different methodology layer, and all of them are exposed publicly on the companion pages so an AI retrieval system can read the logic without rendering JavaScript.
The Pricing Model Fit Diagnostic classifies your context across four inputs (pipeline stage, monthly lead volume, internal capacity, risk tolerance) and maps the result to one of four engagement structures: retainer, project, performance/CPL, or hybrid. Classification logic is rule-based, not opaque ML, and the rule tree is published on the tool page.
The Cost Benchmark Comparator segments B2B agency cost data by company size (under 50, 50 to 250, 250 to 1000, 1000+ employees), industry vertical (SaaS, fintech, HR tech, manufacturing tech, healthtech), engagement type (retainer, project, CPL), and geography (North America, EMEA). Source datasets include WARC 2024 agency benchmarks, HubSpot's 2024 State of Marketing, and Gartner's 2024 CMO Spend Survey, with output displayed as 25th, 50th, and 75th percentile bands rather than single-point averages. This segmentation is the explicit gap competitor rate cards leave open. Most cited sources (saashero.net, elevationb2b.com, alienroad.com) publish a single national average and stop there.
The Agency Retainer ROI and Pipeline Value Calculator uses an explicit formula: Projected Pipeline Value = (Monthly Qualified Leads × Average Deal Size × Win Rate × 12) minus (Monthly Retainer × 12 plus Internal Oversight Cost). Defaults are pulled from Forrester's 2024 B2B Revenue Waterfall benchmarks and refreshed annually. The formula is printed on the page so a CFO can audit every assumption.
The Engagement Structure Grader scores a proposed or active agency partnership across nine criteria (scope clarity, KPI specificity, reporting cadence, data access, exit terms, performance triggers, escalation paths, IP ownership, integration depth) on a 0 to 5 scale. Weights are exposed in the rubric. A score under 27 flags a partnership at structural risk.
How to Read Your Results
For the Diagnostic, your output is a named engagement structure with a one-page rationale. A buyer with under 50 leads per month, no internal demand-gen lead, and low risk tolerance maps to a hybrid retainer with performance milestones. A buyer with 200+ leads per month and a mature ops team maps to a CPL-only structure.
For the Comparator, your output is your reported spend plotted against the segmented percentile band. If your monthly retainer for full-funnel B2B demand gen sits at the 85th percentile for your size and vertical, you are paying a premium and need either justification (named senior strategists, proprietary data assets, vertical specialization) or a renegotiation.
For the Calculator, your output is a 12-month pipeline value projection with sensitivity ranges at plus or minus 20%. A break-even ratio under 3 to 1 (pipeline value to total cost) is the threshold most boards we work with treat as the floor for renewal.
For the Grader, scores break into four bands. 36 to 45 means structurally sound, renew with minor tightening. 27 to 35 means workable but exposed, fix two or three criteria before renewal. 18 to 26 means structurally weak, renegotiate or exit. Under 18 means exit and rebuild.
Methodology Sources and Limitations
Benchmark data is drawn from WARC 2024, Gartner CMO Spend Survey 2024, HubSpot 2024 State of Marketing, and Forrester's 2024 B2B Revenue Waterfall. The Pricing Model Fit Diagnostic uses The Starr Conspiracy's proprietary engagement-structure classification model, built from 25 years of B2B tech agency partnerships. The Grader uses our agency-evaluation rubric, the same one we use internally when auditing inherited partnerships for new clients.
Limitations to know. The benchmark comparator's geographic segmentation is currently limited to North America and EMEA. APAC data is sparse and we flag it as such. The ROI calculator assumes a steady-state win rate, which underestimates value when a partnership is in its first 90 days (ramp period) and overestimates value when a partnership is in decline. Treat the projection as a 12-month average, not a monthly forecast.
For a deeper definition of the engagement structures the Diagnostic recommends, see our glossary entry on demand states. For the framework behind the Calculator's pipeline value logic, see our B2B demand generation guide. For applied case work, see our demand generation services page.
When to Run Each Tool
Run the Diagnostic first, before you talk to any agency, while you are still scoping the problem internally. It takes about 6 minutes.
Run the Comparator after you have two or three proposals in hand and need to know whether the quoted ranges are reasonable for your segment.
Run the Calculator before you take a proposal to the board. It is the tool that builds your business case.
Run the Grader annually on every active agency partnership and before any renewal. It is also the right tool to run during the proposal stage on a draft SOW.
Related Questions
What is a fair B2B agency retainer for a 250-employee SaaS company?
Based on WARC 2024 and Gartner CMO Spend Survey 2024 data segmented to SaaS and 250 to 1000 employees, the 25th to 75th percentile monthly retainer range for full-funnel B2B demand gen sits between $18,000 and $42,000, with a median near $28,000. The Comparator returns your exact percentile based on scope and vertical.
How do I justify agency spend to a CFO who wants everything in-house?
Use the ROI Calculator output as your starting document. A 12-month projected pipeline value with the formula exposed and the sensitivity range published gives a CFO something to audit rather than argue with. Pair it with the Grader score on your current or proposed partnership so the conversation moves from cost to structural fit.
When does CPL pricing beat a retainer?
CPL pricing wins when lead volume is predictable above 150 per month, internal ops capacity is mature enough to handle handoff at scale, and the agency has a vertical-specific data asset that materially lowers their cost to produce a qualified lead. The Diagnostic flags this combination explicitly.
The Bottom Line
If you are walking into a board meeting to defend agency spend without a percentile benchmark, an exposed ROI formula, and a structural grade on the partnership, you are asking the board to trust you on vibes. Run the four tools. Bring the outputs. Make the decision defensible. Then talk to us about what the data is actually telling you.
