The average growing Shopify brand runs dozens of apps. Individually each looks cheap; together they form a second COGS line that never appears next to product cost. Add Shopify Payments tiers and you have a silent margin tax.

## Where the money goes

Common stacks: email, SMS, reviews, upsells, subscriptions, loyalty, inventory, returns, helpdesk, SEO, and “just in case” utilities. Many overlap (two review apps, three analytics apps).

Payment fees scale with volume. A plan upgrade that “unlocks” a lower rate can still lose if app spend grew faster than fee savings.

## Audit method

Export active charges. Tag each app: critical, replaceable, unused (90 days). Kill unused first. Merge overlapping categories. Re-measure true net profit 30 days later.

Track app spend as a percent of revenue. Healthy brands often stay under a few points of revenue; bloated stacks climb without anyone noticing.

## Prevention

Require an owner and a success metric before installing. Quarterly subscription reviews beat annual panic. Surface apps inside the same cost system as COGS and ads.

## FAQ

**Do free apps still cost money?**

Yes—via staff time, storefront performance, and data fragmentation even when the sticker price is $0.
