This guide provides a detailed methodology for comparing the costs of deploying a packaged CDP vs. a composable option.
It is designed for founders, Marketing Ops leaders, and data teams at $5M–$100M revenue companies who:
Are evaluating CDP architecture for the first time
Have received conflicting advice from packaged CDP and composable advocates
Want a data-driven, defensible cost comparison before making a six-figure decision
The four-step CDP Architecture Selection Framework applied to cost scalability
Detailed pricing mechanics for both MTU and event-based packaged CDPs
The real cost structure of warehouse-native builds (including the commonly missed Reverse ETL layer)
How to model Year 1 build + Year 2 run-rate costs
A complete worked example with t-shirt sizing and cost estimates
Scoring methodology to compare both options against your cost ceiling
A clear methodology to define your own cost ceiling and scale assumptions
Deep breakdowns of how costs really accumulate in both models (MTU inflation, destination fees, spike exposure, reverse ETL, tool sprawl, engineering maintenance, etc.)
A worked example using a realistic $5M–$100M D2C company (Glow&Co)
Specific due diligence questions you must ask vendors and contractors
A binary scorecard that delivers a weighted, comparable score for each architecture
Excel-based calculators for quickly calculating packaged/warehouse-native implementation costs
