The honest answer to "what does a custom webshop cost?" is: it depends. Not to dodge the question, but because a webshop isn't a product with a sticker price — it's bespoke software that flexes with what you sell, to whom, and which systems it has to talk to. Below we break down what actually drives the cost, with no sales pitch.
What actually drives the cost
Four things drive the price of a webshop — in this order of impact:
- Scope. A tidy catalogue with checkout and a payment provider is a very different thing from B2B with tiered pricing, customer groups, quotes and an auction module. Every "yes, and also…" moves the budget. Scoping honestly is the biggest lever you control yourself.
- Platform. Magento, WooCommerce or Shopify — the choice decides how much you build versus configure. Shopify is fast to launch but less flexible; WooCommerce is flexible and affordable for SMBs; Magento is heavier but unbeatable for complex B2B. Picking the wrong platform costs more than any design decision ever will.
- Integrations. Accounting, stock, ERP, fulfilment, PIM. Each integration is a project in itself: an API you don't control can break, be slow, or be poorly documented. Two integrations often cost more than the entire storefront.
- Design & content. Tuning a theme is cheap; a bespoke, conversion-focused design with real product photography and copy takes time. It's often wise to start "good enough" here and invest later once the revenue is there.
The path: intro call → design → build
Instead of quoting a big number up front based on assumptions, we work in small steps — so you always know where you stand:
- Intro call (free, no obligation). We look at your plans together: where's the revenue, what truly needs to be in on day one — and what can wait? The online quickscan is a fine first pass.
- Design. A graphic design — often in Figma — that we refine together until it's right. Nothing gets built before your go, so you know exactly what you're getting beforehand.
- Build. We build what you saw in the design, starting with the part that pays off most — the core that has to sell — and ship working software, not slides. An honest estimate upfront; if anything shifts, you hear it immediately.
- Growth. Going live is the start, not the finish. Maintenance, speed and new features at a pace that fits your revenue — cancellable monthly.
We deliberately name no figures here: two shops that look identical from the outside can differ several-fold in build work — the four drivers above decide it. We only name a direction once we know your scope, and then as an honest estimate, not as bait. If anything shifts along the way, you hear it directly — not on the invoice.
How to keep it lean
- Start with half. Launch the version that can make money and build the rest with the revenue it brings in.
- Count your integrations early. Ask up front which systems truly need to be connected on day one — the rest can wait.
- Choose the platform on your business, not the hype. We give an honest answer up front on whether Magento, WooCommerce or Shopify fits you.
- One builder, no middlemen. You talk to the developer who builds it — not an account manager who passes it to a junior.
A concrete example of what "custom where it counts" means: for Blomson we built a B2B Magento webshop with a per-product auction module and Excel upload for overstock — things standard tooling simply can't do. More of that kind of work is in our cases.
In short
There's no catalogue price for a webshop, and anyone quoting one without knowing your scope is guessing. What does exist: an honest conversation that translates your scope, platform and integrations into a concrete plan with an honest estimate per step. Want to know where your shop lands? Run the online quickscan or book a call — and we'll map it out together.
