Custom Shopify theme or a Theme Store theme: how to choose

What a Theme Store theme gives you

Themes on the Shopify Theme Store are reviewed by Shopify before they are listed, and every page is built from sections and blocks that your team adds, removes and reorders in the theme editor without touching code. A theme is free or a one-time purchase, its developer supports it, and new versions come out as the developer improves it and as Shopify adds features.

For many brands that is the right start. A good theme covers the pages every store needs (home, collections, products, cart, search and blog), works with the apps most stores install, and lets the team build landing pages on their own.

What a custom theme adds

A custom theme is written for one store. The design is not limited to the layouts a theme offers, and the templates can carry logic a general-purpose theme does not have: product configurators, bundles built from several products, B2B price display, content from metafields and metaobjects, or data from an ERP or a PIM on the product page.

It also contains only what the store uses. Fewer unused sections and settings mean less code to load and fewer options for the team to sort through. The code belongs to you, and changes never wait on a theme developer’s roadmap.

What each one costs to keep

A Theme Store theme is maintained by its developer. Updating keeps the store current, but edits made directly in the theme’s code do not carry over to the new version, so the more a theme is edited, the more each update costs.

A custom theme has no upstream updates to merge, and no one else keeping it current either. When Shopify ships something new for themes, someone has to bring it into your code. Plan for that time after launch, as part of a support arrangement or in-house.

The questions that decide it

• Does the design need layouts that the theme’s sections cannot produce?
• Does the catalog need product logic beyond options and variants?
• Who changes the store day to day, and do they need to build pages without a developer?
• How soon do you need to launch?
• Who will maintain the theme a year from now?

If most answers point to standard pages, a team that edits on its own and a close launch date, start from a Theme Store theme. If the design or the catalog is the reason the store exists, a custom theme is usually worth its cost.

A middle path: extend a Theme Store theme

Many stores start from a Theme Store theme and add what is missing as new sections and blocks, leaving the theme’s own files as they are, so after an update they only need to be copied across, not merged. That keeps updates manageable while giving the store the few custom pieces it needs. It works as long as the additions stay small: once most templates are rewritten, a custom theme is the cleaner choice.

We build custom themes, and we make our own theme, the Universe theme by Developpy, so we see this trade-off from both sides.

What this means for your store

Choose by what the store has to do, not by how a theme looks in its demo. Start from a Theme Store theme when the brand fits its sections and speed matters most; build a custom theme when the design, the catalog or the integrations are what set the store apart; and if you start from a theme, extend it with new sections rather than rewriting its files.
