Shopify or a custom store: how to decide
An honest comparison between a Shopify store and a custom-built ecommerce, by catalogue, integrations, recurring cost and time to launch.
Short answer
Shopify suits you when you want to sell soon, your catalogue is standard, and the business fits its way of working. A custom store suits you when your product, your logistics or your integrations do not fit that shape, and fighting the platform would cost more than building what you need.
The debate is usually framed as "platform versus development" when it is really "how closely does my business resemble what the platform takes for granted".
What Shopify assumes
Shopify is built on reasonable assumptions: you sell products with variants, you charge through common methods, you ship with known carriers, and your operation fits its order model. If that describes your business, the platform saves you months.
The assumptions break when you sell made-to-measure, by quote, with per-customer pricing, with your own logistics, or when your inventory lives in a system you already use and have no intention of replacing.
Comparison by criterion
| Criterion | Shopify | Custom |
|---|---|---|
| Time to first sale | Weeks | Months |
| Up-front cost | Low | High |
| Recurring cost | Subscription, commissions, apps | Hosting and your own maintenance |
| Standard catalogue | Excellent | No need to rebuild it |
| Complex pricing rules | Limited, app-dependent | No limit |
| Integration with your own systems | Via API and apps | Direct |
| Performance control | Partial | Total |
| Third-party dependency | High | Low |
| Who can maintain it | Many vendors | Whoever built it, or someone who reads its code |
When to choose each
Choose Shopify if you want to validate the channel soon, your catalogue is products with variants, you have no unusual pricing rules, and you would rather pay a subscription than maintain infrastructure.
Choose custom if your product does not fit a standard catalogue, you need to talk to systems that already run your business, performance is part of your ranking strategy, or the accumulated app cost already exceeds what building it would cost.
Start on Shopify and plan to migrate if you are unsure. Validating first and building later is almost always cheaper than building on a hypothesis.
The cost nobody adds up at the start
On Shopify the visible price is the subscription. The real price includes the transaction fee, the apps that cover what the platform does not do, and the theme if you buy one. It is worth totalling that annual figure before comparing it against a build.
On a custom build the visible price is the project. The real price includes maintenance, security updates, and having someone who can touch it two years from now.
Neither option is cheap. They are expensive at different moments.
What applies to both
Whichever you choose, the purchase funnel has to be measured step by step. Without that you will not know which screen loses the sale, and that diagnosis does not depend on the platform.
In short
Shopify if your business fits its assumptions and you want to sell soon. Custom if it does not, or if technical control is part of your strategy. Total the real annual cost of both before deciding, and verify you can export your data either way.
