A good Shopify theme covers 80 to 90% of what a store needs. For the rest, there are two routes: an app or a custom module, meaning a section built specifically for your store. Custom modules pay off when they explain your product better, replace an app or make your brand unmistakable. Very few stores need a fully custom build.
Three levels
| Theme only | Theme plus custom modules | Fully custom | |
|---|---|---|---|
| What it is | A purchased theme, customized in the editor | A purchased theme plus sections only your store has | Your own theme built from scratch |
| Cost | Low | Medium | High |
| Recognition | Limited | High, where it counts | Maximum |
| Updates | From the theme developer | From the developer, modules are kept | Your own job |
| Right for | Getting started, small budget | Most growing brands | Large brands with their own team |
The sweet spot is almost always in the middle: a solid theme as the base, custom modules where they boost revenue or brand.
5 cases where a custom module pays off
- Your product needs explaining. A configurator, a before-and-after comparison, a how-to graphic. No standard theme can do that.
- Replacing an app. If you pay every month for a single feature and the app slows your store down, a custom module is often cheaper after a year.
- Content from metafields. Size charts, ingredients, care instructions per product, neatly managed in the admin and shown on the page automatically.
- Your brand should stand out. A homepage element only you have sticks in people's minds better than the tenth image slider.
- Recurring team tasks. A module your team fills in without a developer saves time every week.
A custom module with us starts at €490, at a fixed price, and your team maintains it afterwards in the theme editor.
Where we don't build custom
Product page, cart and checkout are the heart of the store. Here we rely on what Shopify provides and on proven apps. No custom code in the purchase flow.
The reason is simple: Shopify constantly improves this area with new payment methods, a faster checkout and security updates. Custom code there breaks with every update, or it keeps you from getting the improvements. A store that snags at the buy button loses more than any feature brings in.
FAQ
What is a section? A building block you drag onto a page in the theme editor, such as a banner, a product row or an FAQ block. Custom sections work exactly the same way, just with content and design that only you have.
Do custom modules get lost in a theme update? They aren't carried over automatically, because technically an update is a new theme version. But if the modules are cleanly set up as separate files, they can be moved into the new theme and checked with little effort.
Can I change a custom module myself later? Content, images and colors, yes, via the theme editor. New features need a developer again.
Which theme do you recommend as a base? That depends on your product range and brand. We choose it with you in the intro call.
