Custom e-shop or an off-the-shelf platform? How to choose

Most new online shops should start on a platform. Some businesses outgrow it, and a few need custom development from the start. Here is how to tell which one you are.

Off-the-shelf platforms

Shopify, WooCommerce, Shoptet, Shopware and similar.

Advantages

• Fast to launch, with themes and payment integrations ready.
• Lower starting cost.
• Large ecosystems of apps and plugins.
• Updates and security handled by the platform (for hosted ones).

Limits

• Monthly fees and transaction fees add up as you grow.
• Unusual business logic (custom pricing, B2B rules, configurators, subscriptions with special rules) often means fighting the platform or stacking plugins.
• Many plugins slow the shop down and can conflict with each other.
• Tracking and data quality depend on how well plugins are set up.

Custom-built e-shop

Built for your business, on your own backend or a headless setup (your own front end on top of a commerce engine).

Advantages

• The logic fits your business exactly.
• Full control of speed, data and integrations with warehouse, ERP or CRM.
• No per-transaction fees to the platform.

Limits

• Higher starting cost and longer build.
• You are responsible for maintenance, security and updates, or you pay someone to be.

How to decide

Choose a platform if:

• You are testing a product or market.
• Your sales process is standard: products, cart, checkout, delivery.
• You need to launch in weeks, not months.

Consider custom if:

• Your business logic does not fit the platform and plugins keep breaking.
• Platform fees have become a significant cost.
• Speed and data quality limit your marketing, for example, product feeds and events you cannot control.
• You need deep integration with your own systems.

A middle path

Many shops keep the platform for catalogue and checkout, and build custom parts around it: a configurator, a customer portal, a mobile app, better tracking. It is often the cheapest way to remove a bottleneck.

Whatever you choose, check these

• Page speed on a mid-range phone.
• Clean purchase tracking with correct values and product IDs.
• A product feed for Google and Meta that matches the catalogue.
• A tested checkout in every country you sell to.

These decide how well your ads can work. See also Google Ads for e-commerce.
