## What you need to know

### What is ecommerce total cost of ownership?

Ecommerce TCO is the complete lifecycle cost of acquiring, implementing, operating, supporting, changing and eventually replacing an ecommerce solution.

### How do I calculate ecommerce TCO?

Define a time period and operating scenario, estimate every lifecycle cost and risk, document assumptions, and update the model with actual results.

### What costs should be included in ecommerce TCO?

Include licenses, apps, payments, implementation, migration, integrations, hosting, security, maintenance, labor, training, support, downtime and exit cost.

### Why is platform subscription price not the total ecommerce cost?

Subscription price excludes much of the people, software, transaction, change, and operational work required to achieve the business outcome.

### How should app costs be included in TCO?

Include subscriptions, usage charges, setup, integration, administration, training, data movement, overlap and removal or replacement work.

### How should development costs be included?

Include discovery, design, build, testing, deployment, rework and future enhancement across employees, vendors and opportunity cost.

### How should maintenance costs be included?

Estimate upgrades, defects, monitoring, security, provider changes, regression testing, support, and routine operational care across the lifecycle.

### How should internal labor be included?

Use fully loaded time for administration, merchandising, support, finance, engineering and management, including recurring manual work.

### How should downtime and operational inefficiency be considered?

Model expected lost contribution, recovery labor and repeated process waste using evidence and ranges rather than pretending uncertain costs are zero.

### A quick store check

Build a three-year lifecycle cost model for the current platform with documented volume, labor, and risk assumptions.

## Frequently asked questions

### Is TCO a single precise number?

It is an evidence-based estimate with assumptions, ranges, and scenarios that should be updated with actuals.

### Should revenue benefits be subtracted from TCO?

Keep cost and benefit models distinguishable, so assumptions remain auditable.
