When we take over an existing Shopify store, the first thing we open is the app list. The picture is almost always the same: fifteen to twenty installed apps, each with its own monthly fee, half of them untouched for months. Two overlap in function, one measurably slows the site down, and one was uninstalled but left code in the theme that still loads. The App Store – Shopify itself counts over 16,000 apps there – is a genuine strength of the platform. It is also where stores quietly bleed money and speed.

What apps really cost: fees, load time, dependency

The monthly fee is the most visible price, and often not the biggest. Many apps load their own scripts into the storefront – each one stretches load time on mobile, and slow stores sell less. How much less has been measured: in the Google-commissioned Deloitte study “Milliseconds Make Millions” (2020), a 0.1-second improvement in mobile load time lifted retail conversion rates by 8.4% and average order value by 9.2%. Then there is data access: an app allowed to read orders reads your orders. With a vendor you know nothing about, that is a trust decision worth making consciously.

The third cost only shows up at goodbye: some apps write code directly into the theme, and it stays there after uninstalling. In almost every store we take over, we find remnants of two or three long-deleted apps that still load. Whoever removes an app should check the theme afterwards, or have it checked.

Check first: can Shopify do this natively by now?

Shopify keeps expanding its built-in feature set, and plenty of app-store classics have become redundant. Discount logic, bundles, and volume deals are covered far better by the native discounts and functions than they used to be. Simple email campaigns are handled by Shopify Email. Basic product reviews, metafields for extra product information, gift cards: all on board.

The checking order pays off for every wish: first Shopify’s built-ins, then the theme (many good themes ship countdowns, badges, and the like), only then the App Store. Every avoided app is one fee, one script, and one dependency less.

These categories earn their place

A core set of apps is money well spent, because it either drives revenue or fulfils obligations. For a store in the DACH region that typically means:

Legal: cookie consent management and invoices that satisfy Austrian or German law – that is not optional polish, it is an obligation
Email marketing with automations: abandoned-cart and welcome flows are among the few apps whose effect shows up directly in revenue
Reviews: real customer voices on the product page build trust, especially for unknown brands
Shipping: connections to Post, DPD, GLS and the like with label printing save handling on every parcel
Search and filtering: beyond a few hundred products, the built-in search becomes the bottleneck

The usual suspects on the cut list

Just as clearly, there are categories we almost always remove. Countdown timers and artificial scarcity (“only 2 left!” while the warehouse is full) read as cheap rather than persuasive on a serious brand. Pop-up cascades that hit visitors with newsletter, discount, and cookie banner in the first seconds cost more checkouts than they win. And duplicates – two review apps, two SEO apps – are simply double fees for single functionality.

Be wary, too, of apps promising to “optimize SEO automatically”. Editing titles and descriptions is something Shopify does natively; what these apps add on top is often cosmetic, and occasionally harmful when they inject masses of generated text.

When a custom app is the better deal

Sometimes the need is real but no store app fits: pricing logic that only exists in your industry, a configurator for your products, a bridge to an internal system. The usual reflex is to combine three standard apps and fill the gaps with manual work. That works, but permanently costs three fees plus the manual work.

The alternative is a private app: built once, runs only in your store, does exactly what you need, no monthly fee to a third party. For a single small feature, that rarely pays off. But as soon as several apps have to be combined and patched with workarounds, the math often flips within a year or two – and the store gets faster along the way, because third-party scripts disappear.

The one-hour app audit

You can take the first step yourself. Go through the installed list and ask three questions per app: when did I last open it? What concretely breaks if it is gone tomorrow? And do I know what it costs per month? Apps without a good answer get removed on a trial basis – almost everything can be safely uninstalled, and reinstalled just as easily.

Then look at load time, for instance with PageSpeed Insights, measured before and after. The difference after a cleanup surprises many merchants. If you suspect leftovers from deleted apps in the theme code, or are unsure which app carries which function: this kind of cleanup is exactly what we do regularly.
