STRATEGIC MATURITY MODEL

OVERVIEW

Designed for DTC and transactional e-commerce businesses generating up to £10M in annual revenue, this analytics framework leverages the Google Ecosystem (BigQuery + Data Studio) to accurately evaluate LTV, margin contribution, and customer repeat behavior.

It takes brands from raw, unsegmented transaction data to true Strategic Maturity by eliminating the mathematical distortions of top-line arithmetic means.

Strategic Outcomes

• Metric Paradigm Shift: Moves core focus away from vanity metrics (ROAS & traffic volume) to order-level Contribution Margin (CM2) and 2nd-order conversion efficiency.
• Exact Profit Payback Timing: Identifies the precise time window (in 15-day distribution buckets) when a customer cohort pays back acquisition costs and becomes contribution-margin positive.
• Order 1-to-2 Conversion Precision: Maps exact time-lag waves (15–30, 31–45, 46–60 days) to ground automated CRM flows in actual buyer behavior rather than skewed global averages.
• One-Time vs. Repeat Segment Isolation: Distinguishes high-value multi-order buyers from single-order drop-offs without subscription (SnS) noise.
• Cohort-Driven Revenue Forecasting: Uses historical order-grain cohort performance to project future repeat revenue and customer lifetime value.

Strategic Questions Answered

• Gross Margin Velocity: How many days does it take for a customer cohort to generate enough Contribution Margin (CM1) to clear its initial acquisition threshold?
• Lifecycle Purchase Timing: Within each 15-day distribution window (16–30, 31–45, 46–60), at what specific peak day intervals (Day 23, Day 38, Day 53) do customer cohorts naturally re-order without relying on paid retargeting?
• Net Unit Profitability: What is the true, fully loaded order-level margin (CM2) after deducting landed COGS, merchant gateway fees, and pick-and-pack fulfillment costs?
• Cohort Margin Retention: What percentage of acquired first-time buyers convert into multi-order repeat customers versus dropping off after Order 1?
• Repeat Revenue Trajectory: Based on historical time-lag velocity, how much contribution margin will current active customer cohorts generate over the next 30, 60, 90, and 365 days?

THE FRAMEWORK

The repository is organized into four distinct modules:

Module	Scope	Description
1.0	Validation	Data integrity guardrails ensuring financial accuracy and single-source-of-truth alignment.
2.0	Segmentation	Customer purchase frequency, profit-bucket stratification, and baseline channel health.
3.0	Migration & LTV	Matured milestone tracking (30, 60, 90, 180, 365 days) and year-over-year cohort behavior.
4.0	CAC & Payback	Blended CAC payback windows, marketing efficiency metrics, and capital allocation modeling.
5.0	Behavioral Audit	Order 1 to 2 conversion bridges, repurchase time-lag intervals, and late-money yield auditing.

LIGHTWEIGHT SANDBOX: GOOGLE SHEETS LTV TEMPLATE

Before deploying a full cloud infrastructure (BigQuery + Looker Studio), teams can validate their core unit economics, cohort behavior, and bridge metrics locally using the included Google Sheets LTV Starter Model.

This spreadsheet mirrors the logic executed in BigQuery, making it an ideal prototyping sandbox for smaller datasets or pre-pipeline data modelling.

https://docs.google.com/spreadsheets/d/1piQJXYqLxgbeNgUCNmA902QwG2YnptvYeJZIjDwZKyk/edit?usp=sharing

Google Sheet 3. KPI_Dashboard (Executive Summary)

Surfaces core health KPIs generated from the raw transaction data:

• Total Acquired Cohort & Bridge Crossings: Measures conversion performance from 1st to 2nd purchase.
• Bridge Conversion Rate %: Evaluates product-market fit and repeat adoption strength.
• Purchase Velocity & Time-Lag: Tracks average days required to convert buyers to their second order.
• Initial vs. Repeat AOV: Compares upfront basket scale against secondary order value.

When to Transition from Google Sheets to Google BigQuery

Evaluation Metric	Google Sheets Starter	BigQuery + Looker Studio
Data Volume	Best for < 25,000 transaction rows	Scalable to millions/billions of records
Execution Speed	Real-time formula recalculation	Distributed cloud engine (SQL)
Automation	Manual CSV copy-paste	Automated scheduled pipeline ingestion
Use Case	Prototyping & quick health checks	Production auditing & executive reporting

DATA FOUNDATIONS

The most critical step is collecting the right data and getting the right data structure.

Example: Order-Level Profit Waterfall Analysis

To show how dynamic costs are subtracted upstream before reaching the reporting view, here is a financial waterfall breakdown for a sample order selling a Smart Jacket for £90.00:

Cost Component	Type	Amount (£)	Running Balance (£)	Calculation / Sourcing
Gross Retail Price (AOV)	Revenue	+£90.00	£90.00	Initial Cart Value
Discounts & Promo Codes	Deduction	-£9.00	£81.00	10% Welcome Discount code applied at checkout
Net Order Revenue	Subtotal	£81.00	£81.00	Gross Revenue - Discounts (Top-line revenue exposed to view)
Product COGS	Operational Cost	-£25.00	£56.00	Direct unit manufacturing & freight landed cost per SKU
Payment Gateway Fee	Transaction Fee	-£1.82	£54.18	Shopify Payment fee (~2.0% + £0.20 per transaction)
Pick, Pack & Shipping	Fulfillment	-£6.50	£47.68	Warehouse picking labor + outbound courier delivery fee
Packaging & Returns Provision	Variable Ops	-£2.50	£45.18	Branded box, unboxing materials, and blended return rate allowance
Order Net Profit	Final Margin	£45.18	£45.18	Net Contribution Margin (Used in reporting view)

Data Lineage & Upstream Profit Modeling

While view_order_grain_master exposes a clean profit column (e.g., the £45.18 calculated above) for LTV cohort modeling, calculating order-level net margin is highly business-specific and computed upstream

Upstream Staging Pipeline

1. Raw Order & Line Item Extraction: Normalizes raw cart transactions, line items, and fulfillment events.
2. Dynamic COGS & Fulfillment Attribution: Joins SKU-level product costs, picking/packing expenses, and variable shipping fees.
3. Gateway & Discount Reconciliation: Subtracts payment processor fees (e.g., Stripe/Shopify Pay), merchant fees, and distributed discount codes.
4. Final Order-Level Grain: Aggregates order-level gross revenue and net profit before handing off to view_order_grain_master.

Note: The cohort models, LTV trajectories, and CAC payback calculations in this repository assume profit represents true order contribution margin ($\text{Net Sales Revenue} - \text{COGS} - \text{Variable Operational Costs}$).

Data Requirements

The data requirements to build the view_raw_transactional_customer_ordertable

• customer_id
• order_date
• revenue
• profit

Key watchouts:

• The order_date is always YYYY-MM-DD i.e., 2026-06-13

• Revenue and Profit values are not mixed up i.e., profit is not greater than revenue

• Ensure both are numeric not text

• Consistency of customer_id its always lowercase or uppercase and not mixed

• Ensure there’s no trailing space

• No duplicate records

• Storage Agnostic: Whether plugged directly into BigQuery or a Google Sheet, missing these checks causes broken joins, silent aggregation errors, or distorted LTV curves.

• Format Enforcement: Google Sheets is particularly prone to text-formatted numbers and trailing spaces in string IDs, whereas BigQuery enforces data types strictly at the schema level.

This Google Doc provides an example of the data required, how it should be structured.

TESTING

To get started I have shared two testing datasets.

Red Dataset - dataset with many errors

https://docs.google.com/spreadsheets/d/1og04NJxjfeBYWcuTw5WFuoWs5siGREiIdg6Oqa5wMgw/edit?usp=sharing

Run module 1.0 - Data Integrity & Validation it should throw out multiple errors meaning till the data gets fixed it cannot proceed any further

Green Dataset - the pefect dataset, with clean, structured data

https://docs.google.com/spreadsheets/d/1aY6ut88A6mO_ZCtAPMZAAxOZxihWw9qk2FjWtaS6SUM/edit?usp=sharing

Run all modules. 4.1.3 should be an interesting one to understand

EVOLVING THE DATA REQIREMENTS TO DO GEO + PRODUCT LTV

To better understand product LTV the data requirements are:

• customer_id
• order_date
• product_id (sku_id)
• product_name
• revenue
• profit

To better understand geo LTV the data requirements are:

• customer_id
• order_date
• city_id/postcode
• city_name
• revenue
• profit

The master view would comibne customer + product + geo

• customer_id
• order_date
• product_id(sku_id)
• product_name
• city_id/postcode
• city_name
• revenue
• profit

LTV STRATEGIC CALCULATOR (SCENARIO PLANNER)

A calculator designed to translate raw customer data into a high-level growth insights. It isolates the "First Order" cost of acquisition from the "Bridge" (2nd order) to lifetime profitability.

https://docs.google.com/spreadsheets/d/1q2Ah-IfcfJ73Ik6Fc-FeK-5Kp9aRrTUNTmpf2V__aiw/edit?usp=sharing

The calculator is dynamic with the goal to better undersrand Profit Per User. It automatically scales based on AOV and Bridge targets, showing exactly how much additional CAC can be afforded as back-end efficiency improves.

Key Metrics (Section 2)

These metrics represent the Net Profitability of your acquisition engine.

Metric	Unit	Definition
Day 0 Net Cash Flow	£ Total	The total profit or loss for the cohort after subtracting Marketing Costs (CAC) from the initial Gross Profit.
Month 12 Cohort Profit	£ Total	The estimated total profit from this group after 1 year, including repeat "Bridge" revenue.
Max Allowable CAC	£ / User	The break-even ceiling; the maximum you can spend to acquire a user while breaking even over 12 months.
Current Profit Gap	£ / User	The "Marketing Treadmill"—the net profit or loss realized on the very first transaction per user.

Growth Levers (Section 4)

This section quantifies the financial impact of specific strategic interventions per user.

Metric	Unit	Definition
Baseline LTV	£ / User	The current total projected profit value of a single customer over 12 months.
Improve Bridge (+10%)	£ / User	The incremental profit gained per retained customer by improving the retention bridge efficiency by 10%.
Increase Order 2 AOV	£ / User	The profit added to every user in the cohort by increasing repeat spend by £10.
Profit Per User	£ / User	Profit Lift (Orders 1-2). The additional profit realized per user by optimizing the path from the first to the second purchase.
Profit Swing	% / User	Turnaround Magnitude. Measures the total value created by the strategy (Moat + Gap recovery) relative to the initial loss.

Calculating Unit Economic Lift

When improving both Retention and AOV, it gains a "compounding bonus", newly retained customers are also spending at the higher AOV.

The Formula:

Total Lift = (New AOV × Margin × New Bridge Rate) — (Old AOV × Margin × Old Bridge Rate)

How to Use Google Sheet - LTV Strategic Calculator

1. Input Data: Input into the blue cells: Monthly Users, CAC, AOV, and Margins (Section 1 and 3).
2. Review the Gap: Check the Current Profit Gap. If it is negative, you are paying a "fee" to acquire customers and relying entirely on the "2nd purchase" to reach profitability.
3. Simulate Growth: Profit Per User and Max Allowable CAC provide the Strategic Insights to outscale competitors.
