Milestone 14. Customer Journey & CAC

Map the womb-to-tomb customer journey, lock CAC as a percentage of gross profit, install the SLAs that end the sales-marketing argument, and run revenue from leading indicators instead of war stories.

Phase 2 (Build) · Module 5 (Predictable Revenue) · Milestone 14 of 27

The owner’s question

Can your CRO tell you the CAC by channel, where each channel sits against the guardrail, and which conversion stage is the constraint, in 90 seconds with specific numbers?

If the answer is “let me put something together” or “marketing is working on a report,” you’re not at a 3 yet.

TL;DR

Most owners pay for marketing and sales without knowing their actual customer acquisition cost, run sales and marketing as two separate functions that argue about leads, and review dashboards full of vanity metrics nobody acts on. Milestone 14 ends all three problems. You map the customer journey end to end through five stages (Awareness, MQL, SQL, Customer, Retention), calculate fully loaded CAC by channel, lock a guardrail as a percentage of gross profit, build the LTV per segment with an LTV/CAC ratio target of 3 or better, document the SLAs that end the “whose lead is it” debate, and wire a Revenue KPI Dashboard of leading indicators into the weekly CRO review and the MOM Financial Signal Review. The CRO answers “are we going to hit the number?” with data instead of gut feel.

Why this matters

Sales says marketing sends garbage leads. Marketing says sales does not follow up. The owner watches both sides argue and cannot figure out who is right.

Most owners think this is a people problem. It is not. It is a clarity problem disguised as an alignment problem. Two functions operating from two different definitions of “qualified,” with no shared journey to anchor the conversation, no service-level agreement defining who owns what, and no financial guardrail forcing both sides to operate within the same constraints. While that argument plays out, money keeps going out the door.

Kim Clark was coaching an owner whose marketing director claimed that spending 30 to 40 percent of total revenue on marketing was “good ROI.” Think about that. A $5 million business spending $1.5 to $2 million on marketing, before sales compensation, before delivery, before overhead. That is not a guardrail. That is a fire.

And most owners do not actually know their customer acquisition cost. They count the marketing line and call it a day. The real number, the full loaded cost of turning a stranger into a customer, is significantly higher. Sales compensation. Business development. Operations and tooling. Onboarding costs. It is the number that determines whether the revenue engine is building value or burning cash. Without it, every spending decision is evaluated on vibes instead of math.

Milestone 14 ends both problems. It maps the womb-to-tomb customer journey from first awareness through long-term retention. It calculates CAC by channel, locks a guardrail expressed as a percentage of gross profit, builds the SLAs between sales and marketing, calculates LTV per segment to compute the LTV/CAC ratio, and wires the leading-indicator Revenue KPI Dashboard the CRO uses to govern weekly. Sales and marketing stop arguing because the system removes the ambiguity that fueled the argument.

What this looks like when it’s installed

The owner of Advanced Solutions entered Year 2 with no real CAC, no documented customer journey, and a CRM half-used by a sales team and ignored by marketing. After M13 locked the Revenue Architecture in Q4 of Year 1, the Q1 Year 2 90-Day Game Plan™ was M14. The CRO (fractional at that point) plus the marketing director ran a five-week sprint. The customer journey got mapped end to end with conversion criteria per stage. CAC was calculated by channel for the first time, fully loaded: $4,200 per customer through inbound, $11,800 through outbound, $1,400 through referral. The guardrail locked at 18 percent of gross profit. Outbound was breaching the guardrail, so the channel was paused for redesign. SLAs got documented and the “whose lead is it” debate ended that quarter.

By Year 3, conversion rates climbed: 8 percent awareness-to-MQL grew to 11 percent, 22 percent MQL-to-SQL grew to 31 percent, 35 percent SQL-to-customer held steady. Pipeline velocity became the headline metric in Wk1 of the CRO meeting. By Year 5, the journey was muscle memory, CAC held inside the guardrail for four consecutive years, and customer concentration dropped below 18 percent because the journey filtered wrong-fit customers out before they consumed sales capacity. Revenue at $20M with healthy unit economics. That’s what “installed” looks like for M14. Not a funnel diagram on a slide. A five-stage system the CRO runs every week. Full walkthrough: see the Case Study Reference.

Score yourself

Score yourself honestly against where you are right now. The verification test at the bottom is what separates a real 3 from a wishful 3.

0 (Not Started). You haven’t engaged with the material. You can’t name your CAC. Sales and marketing run as two separate functions. The dashboard (if you have one) tracks clicks and impressions, not pipeline velocity. Default starting point.

1 (Learning). You can articulate the five-stage journey (Awareness, MQL, SQL, Customer, Retention). You can explain why CAC is bigger than the marketing line. You can explain LTV/CAC and the typical target of 3 or better. You can name the difference between vanity metrics and leading indicators. No deliverables built yet.

2 (In Progress). Customer Journey drafted at the stage level. CAC calculated for the top 1-2 channels (not all). LTV not yet calculated by segment, or calculated but with no LTV/CAC ratio computed. Sales + Marketing SLAs partially documented (qualified lead definition shared but handoff still messy). KPI dashboard tracking some metrics but not the full leading-indicator set. CAC guardrail not yet locked or not tied back to gross profit.

3 (Installed). Customer Journey mapped end-to-end with touchpoints, conversion criteria, drop-off triggers, and ownership (sales / marketing / customer success) per stage. CAC calculated fully loaded for all material channels and segments. CAC guardrail locked as a percentage of gross profit (typically 10-30% depending on business model) and monitored monthly. LTV calculated per segment with LTV/CAC ratio computed (target ≥ 3 with payback ≤ 12-18 months SMB or ≤ 24 enterprise). SLAs locked with documented qualified lead definition, opportunity criteria, handoff protocol with response-time commitments. KPI dashboard tracking the full leading-indicator set (pipeline velocity, conversion rate by stage, average deal size, time to close, NRR). Reviewed weekly by the CRO and monthly in Wk1 of the Tuesday Flywheel (CRO functional review) and the MOM Financial Signal Review.

The verification test. Walk this out loud right now. “Our CAC is $[X] by inbound, $[Y] by outbound, $[Z] by referral. Our guardrail is [N] percent of gross profit, and channel [A] is the one currently sitting closest to the line. Our LTV/CAC ratio is [N] with payback at [X] months. Our biggest conversion gap is the [stage]-to-[stage] step, currently at [N] percent vs target [M] percent. The lever we are pulling this quarter is [specific lever].” If you can do that in 90 seconds with specific numbers and a specific lever, you’re at a 3. If you stumble or say “let me check,” you’re at a 1 or 2.

Build these five things

Five deliverables. Roughly 40 to 60 hours of focused work the first time, spread across 4 to 6 weeks. Run by the CRO (or fractional CRO, or the owner if no revenue leader exists yet). Most steps depend on data the existing systems may not have cleanly today. The full canonical Exercise templates and AI Interview Protocols that walk you through each one live inside the Member version of the iBD Ownership OS™ that paying clients fork.

#DeliverableWhat it does
1Customer Journey MapWomb-to-tomb: five stages (Awareness, MQL, SQL, Customer, Retention) with touchpoints, conversion criteria, drop-off triggers, and ownership (sales / marketing / customer success) per stage. The structural design the rest of the milestone runs against.
2CAC Calculation + GuardrailFull-loaded CAC per channel and per segment, expressed as a percentage of gross profit. Sets the maximum spend per channel that the unit economics can sustain.
3LTV Calculator + LTV/CAC RatioAverage revenue × gross margin × retention period, divided by CAC. The math that tells you whether each channel is sustainable, healthy, or exceptional. Target ≥ 3 ratio with reasonable payback period.
4Sales + Marketing SLAQualified lead definition, opportunity criteria, handoff protocol, response-time commitments. The end of the “whose lead is it” debate.
5Revenue KPI DashboardLeading indicators only: pipeline velocity, conversion rate by stage, average deal size, time to close, NRR. Reviewed weekly by the CRO; monthly in the MOM. Vanity metrics deprioritized.

Run them in this order:

  1. Customer Journey Map first. Pull 12 to 24 months of pipeline and closed-won and closed-lost and churn data, tagged by channel, segment, and offer. Then map the five stages with touchpoints, conversion criteria, drop-off triggers, and ownership per stage. Use the M13 Revenue Architecture ICP to anchor the design. The journey has to fit the customer you defined.
  2. CAC Calculation + Guardrail second. Calculate CAC by channel fully loaded (marketing spend + sales compensation + business development + ops + onboarding) divided by customers acquired through that channel. Express the guardrail as a percentage of gross profit, not revenue. Most owners discover their actual CAC is meaningfully higher than they thought.
  3. LTV Calculator + LTV/CAC Ratio third. Average revenue per customer × gross margin × expected retention period per segment. Compute LTV/CAC per channel and per segment. Target ≥ 3, with payback period ≤ 12-18 months for SMB and ≤ 24 months for enterprise. Channels falling short of the ratio are the ones to redesign or shut down.
  4. Sales + Marketing SLA fourth. Qualified lead definition (lead score threshold, ICP match, engagement history). Opportunity criteria. Handoff protocol with response-time commitments. Service-level standards. Document. End the alignment argument.
  5. Revenue KPI Dashboard fifth. Pipeline velocity, conversion rate by stage, average deal size, time to close, NRR. Vanity metrics (clicks, impressions, raw MQL count) get deprioritized. Wire into Wk1 of the Tuesday Flywheel (CRO functional review) and into the MOM Financial Signal Review section. CAC vs guardrail is a standing item on both.

And then the move that separates a 2 from a 3. Make one real allocation decision in the next 90 days using the CAC guardrail. Pause a channel that’s breaching the guardrail. Shift budget from a high-CAC channel to a low-CAC channel based on the LTV/CAC ratio. Hire (or refuse to hire) a sales rep based on what the unit economics support. One specific decision, documented, made from the dashboard. That’s what flips this milestone from documented to alive.

Take your next action

At Level 0 (Not Started). Get exposure to the womb-to-tomb customer journey first. The fastest path is the iBD Ownership OS™ Workshop — three hours, $100, walk out with your Velocity Score™ baseline and a working introduction to the five stages and the CAC guardrail math.

At Level 1 (Learning). Block 90 minutes on your calendar this week. Pull last 12 months of pipeline data tagged by channel. Sketch the five stages with conversion criteria. Calculate a rough CAC for your top 2 channels. The full canonical templates and the AI Interview Protocols live in the Member version of the OS that paying clients fork; the Workshop gives you working drafts to start.

At Level 2 (In Progress). Lock the fully-loaded CAC math. Compute LTV per segment and the LTV/CAC ratio. Document the SLAs. Wire the KPI dashboard into the CRO weekly + MOM monthly. Make one real allocation decision in the next 30 days using the guardrail.

At Level 3 (Installed). Maintain. Review CAC guardrails monthly in Wk1 of the Tuesday Flywheel. Review the full KPI dashboard weekly with the CRO. Re-rate CAC guardrails quarterly if unit economics shift. Re-rate yourself if a channel breaches for 2+ months, if the LTV/CAC ratio drops below 3, or if the dashboard stops shaping decisions.

Where this lives once it’s running

The journey and CAC are the most active layer of Module 5. They move weekly.

Weekly. The CRO reviews the KPI dashboard. Pipeline velocity, conversion movement, new opportunities, NRR. The early signal layer. Coverage shortfalls in the pipeline (per M15 forecast) and CAC breaches in any channel both trigger immediate action.

Monthly Tuesday flywheel. Wk1 is the CRO functional review. Revenue vs forecast, pipeline coverage, conversion by stage, CAC vs guardrails, cycle time, NRR. The CRO presents the data, prepared in advance. The MOM Financial Signal Review uses the same dashboard. The owner asks questions. Drift between KPI trends and forecast gets flagged.

Quarterly. Customer Journey reviewed for friction points at the Quarterly Boardroom. CAC guardrails recalibrated if unit economics shift. CAC and LTV trends reviewed against the valuation drivers in M12.

Annually. Full Customer Journey reassessment at the Annual Owner’s Reset. Are there new stages? New channels? New segments? CAC guardrails re-rated against updated unit economics and the M11 Annual Budget targets.

If you don’t have the cadence built yet (you’re working M14 for the first time and M8/M9 haven’t been installed), run your own weekly KPI review and monthly CAC review against the dashboard. Pull up the journey map. Compare actual conversion to target. Make at least one decision (kill a channel, shift budget, redesign a stage). The cadence formalizes later. The discipline of running revenue from the dashboard starts now.

How this fits in the OS

Prerequisites. Milestone 13: Strategic Plan (the Revenue Architecture that defines the ICP the journey is designed for). Milestone 10: Three-Statement Model (the gross profit number the CAC guardrail is expressed against). Milestone 11: Annual Budget (the CAC budget envelope the guardrail enforces). Without these, the journey floats and the CAC math is theoretical.

What this feeds. Milestone 15: Revenue Systems & Forecasting uses the conversion rates from the customer journey to build the bottom-up forecast. The CAC and LTV math feeds the unit economics that drive the Milestone 12: 5-Year Forecast valuation work. Milestone 16: Target Gross Margins consumes the LTV-by-segment data to refine the per-offer gross margin discipline. Milestone 17: Operational KPIs integrates the Revenue KPIs into the broader KPI architecture. Milestone 19: 3 Functional Leaders defines the CRO seat against the revenue engine installed here.

Where it sits. Second milestone of Module 5 (Predictable Revenue). M13 set the strategy (who you serve, why you win). M14 makes the strategy operational (how customers move through the engine, what each conversion costs, who owns what). M15 makes both accountable (systems, data, bottom-up forecast). Together, M13 + M14 + M15 turn revenue from the owner’s personal effort into a CRO-run engine that produces a defensible top line.
