## What you need to know

### How much can ecommerce apps add to operating cost?

Apps can become a material stack cost through subscriptions, usage tiers, integration, administration and overlapping capability, even when each fee looks small.

### How do I know whether an ecommerce app is worth paying for?

An app is worth paying for when attributable business value or avoided cost exceeds its full lifecycle cost and risk.

### How should app ROI be calculated?

Compare incremental profit, savings or risk reduction with subscription, usage, implementation, labor, maintenance and switching cost over a defined period.

### Should apps be reviewed for usage?

Yes. Review active users, feature use, supported processes, measurable outcomes, incidents and renewal cost rather than login activity alone.

### How do I identify apps that duplicate platform functionality?

Compare installed capabilities with current platform features and other tools, including partial overlap that still creates duplicate data and work.

### Can removing apps reduce cost and complexity?

Yes. Removing justified redundancy can lower fees, scripts, access, performance burden and reconciliation, but requires dependency and data-retention planning.

### A quick store check

Review the highest-cost apps for active capability, attributable value, overlap, incidents, and safe removal requirements.

## Frequently asked questions

### Can low app usage still be valuable?

Yes, if the capability prevents meaningful risk or serves an important occasional process.

### Does cancelling a subscription remove its data?

Not necessarily. Follow export, retention, revocation, and deletion requirements.
