Build an online shop yourself or have it built?
Much of what goes into an online shop can be built in-house — the question is whether it pays off. When in-house work makes sense, where the limit is, and which path is the most expensive.
Building an online shop yourself pays off when the project stays small, someone in the business has time for it, and no one depends on it going live on a specific date. As soon as other systems need to be involved or someone is liable if it fails, external implementation is usually cheaper — the most expensive path is the half-finished one.
01 — In-house effort
Build yourself or have it built?
- Building yourself makes sense when someone in the business has the time and interest, the project stays small, and no one depends on it being live by a specific date.
- Ready-made platforms get you to a first result quickly, but hit limits where custom processes, custom data, or integrations with existing systems come into play.
- Having it built pays off as soon as the online shop needs to communicate with other systems, as soon as someone is liable if it doesn't work, or as soon as the internal effort becomes more expensive than external implementation.
- The most expensive path is the halfway one: built in-house for months on the side, then abandoned and rebuilt externally. If you decide on in-house effort, set a time budget and an abort point.
- Hybrid approach: Concept and setup external, maintenance internal. For online shops, this is often the most economical path — provided the handover is documented.
02 — Requirements
What you need for an online shop
- A clearly defined trigger. Not “we should do something with AI,” but a process that demonstrably costs time or orders today.
- Existing content or data. An online shop works with what's there. The more complete the starting position, the shorter the setup.
- Access to the systems involved. Whoever manages the credentials needs to be involved from the start — this is, in our experience, the most common cause of delays.
- One decision-making contact person. One, not three.
- Willingness to refine after launch. The first weeks in real operation show what was missing in the concept. That's normal and accounted for.
03 — Calculation
How to calculate it
Four numbers are enough: How often does the process occur? How long does it take? What does an hour cost internally? And what does the solution cost — one-time plus operation over three years?
An example: A process that occurs twice a week and takes 40 minutes each time ties up around 69 hours per year. At an internal hourly rate of 45 euros, that's roughly 3,100 euros per year locked in there. If a solution reduces this effort by two-thirds, it often pays for itself — depending on the actual quote — within one to two years. We'll give you the exact figure for your case after the initial meeting.
This calculation is deliberately conservative: it only accounts for the time saved, not the errors avoided or the orders that come through due to faster response. In practice, the benefit is usually higher — but you shouldn't count on it before you've measured it.
04 — Questions
Frequently asked questions
Shopify, WooCommerce or something else?
Shopify if you want to start quickly and can live with the ongoing fees. WooCommerce if you already run WordPress and have someone who does updates. With complex inventory management, it's worth looking at specialized systems. There's no answer that's right for everyone.
What does ongoing operation cost?
Platform fees, payment providers, hosting and maintenance are ongoing costs, even before the first order comes in. How much that is in each case depends on the chosen platform and the product range — we calculate this transparently in the quote so there are no surprises.
Can we migrate from an existing shop?
Yes, with transfer of products, customers and order history. Redirects from the old product URLs are important — without them you lose the visibility of the previous pages.
How many products are still manageable without expensive additional systems?
Up to a few hundred products, the standard features of common platforms are perfectly sufficient. Only with several thousand products with complex variants is it worth looking at specialized inventory management.
How does VAT work for EU shipping?
Above the threshold, tax is paid in the destination country, usually through the One-Stop-Shop procedure. The store must calculate tax rates correctly for each country — this is set up during setup and isn't a detail you patch afterward.
What about returns?
The cancellation policy and the technical process for returns are part of the legally compliant basic setup. How you handle returns in practice remains your decision — we implement what you define.
Can we sell internationally?
Yes, that's a matter of setup, not platform: languages, currencies, shipping zones and tax rates per target country need to be configured properly — we plan that in from the start if desired.
05 — Decision
How to move forward
The most affordable next step is a conversation, not a quote. Twenty minutes is usually enough to clarify whether a project makes sense, what scope it involves, and whether we're the right fit.
If we're not, we'll say so. An honest no costs less than a project you abandon after three months — for both sides.
