The Shopify App Store fixes almost any gap in minutes, which is exactly the danger. Established stores wake up running thirty apps, paying hundreds monthly, with a storefront that loads like it is towing them all behind it. Apps are not bad; unaudited accumulation is.
Before installing anything, ask three questions
- Does the theme already do this? Modern themes ship with quick views, mega menus, sticky carts, and product recommendations that merchants rebuy as apps without checking.
- Will this pay for itself measurably? A review app that lifts conversion has a number attached; a widget that felt nice does not.
- What does it cost at your next order of magnitude? Per-order and per-contact pricing that is cheap today can dominate your P&L after growth.
The categories that usually earn their keep
Reviews, email and SMS automation, subscription billing where the model fits, bundling and upsells done tastefully, and back-office tools for inventory, shipping, and accounting reliably return more than they cost. The graveyard of wasted spend is mostly duplicated theme features, trust badges nobody sees, and analytics dashboards that restate what Shopify reports free.
Audit quarterly, uninstall properly
List every app, its monthly cost, and the specific job it does. No answer means uninstall. Overlapping answers mean consolidate, since suite apps increasingly cover reviews, loyalty, and upsells in one subscription and one script payload. After uninstalling, check the theme for leftover code, because many apps do not clean up after themselves, and orphaned scripts keep dragging speed with zero benefit.
Treat every subscription like a hire: it needs a job description, a measurable output, and a review date.
