Ecommerce development
Ecommerce development
We build and connect e-commerce: from a scalable storefront to the marketplace, payment and warehouse integrations and the numbers behind it. The code stays yours.
- 6+ sources connected
- One live source of truth
- Fixed price up front
- Code stays yours
In short
Ecommerce development is more than a nice shop window. We build the storefront on a scalable platform and then connect the parts that actually matter: marketplaces like bol.com and Amazon, your payment provider, your warehouse and the numbers behind it. For an e-commerce scale-up we brought 6+ sources together into one live source of truth. Fixed price up front, and you keep 100% of the code.
What gets in the way
Most webshop agencies stop at the shop window. But that's where it starts. Because the moment you start selling, your numbers scatter: revenue in the shop, fees in the marketplaces, costs in the warehouse, ad spend in the ad platforms. And then nothing lines up anymore. We build e-commerce from both sides. The storefront itself, on a platform that grows with you. And everything behind it: the integrations to marketplaces, payment providers and warehouse, plus a layer that pulls all those scattered numbers into one set you can actually steer on. No vendor lock-in, no open-ended bill. We think along with you: we listen first to what you want to achieve now and where you are heading, then choose the technology to match, for the most scalable and powerful result that is cost-efficient at the same time.
Your numbers live everywhere and never on time
Revenue in the shop, fees in the marketplaces, costs in the warehouse, ad spend somewhere else. Every week you stitch it together by hand, and by then it's already stale.
A marketplace feed that stops is spotted too late
A bol.com or Amazon feed that dies, a payment status that never comes back, stock that won't sync. Without monitoring you only notice when a customer complains.
The platform doesn't grow with you
A shop that ran fine at 50 orders a week chokes at 500. Plugins that clash, a checkout that stutters, and nobody who knows where it breaks.
You're stuck with the agency that built it
No access to the source code, everything routed through one party, and every change is a new quote. A disguised subscription trap instead of software that's yours.
What we build
How we help
A webshop on a scalable platform
Shopify when it fits, headless or custom when you need it. Fast, mobile-first, and built to grow from your first order well into serious volume.
Marketplace integrations (bol.com / Amazon)
Sell across channels without doubling the work. We connect marketplaces like bol.com and Amazon so orders, stock and fees land in one place instead of in separate portals.
Payment and warehouse integrations
Your payment provider and your warehouse or WMS plugged into the shop, with validation, retry logic and source-health monitoring. So a missed payment status or a feed that quietly dies doesn't slip past you.
The numbers behind it, in one live source of truth
A KPI dashboard that calculates revenue, gross margin, AOV, churn and active users and shows the channel split across your different sales channels. Live, not weekly, with all your sources brought into one model.
Your shop stays yours
The full source code is and stays yours. No lock-in, no hidden dependency. A fixed price up front, no open-ended bill.
Our approach
From idea to working software in four phases
Every project runs through the same four phases, so you always know what's happening, what comes next and what it costs — from first call to live software, usually in weeks rather than months.
- 01 Phase 1 Free intake
Understand & analyse
Everything starts with a good conversation. We map your goals, processes and the bottlenecks worth solving — no sales pitch, just an honest read on where the biggest win sits.
- 02 Phase 2 Free blueprint
Blueprint & quote
We turn the analysis into a blueprint: a clear plan showing exactly which steps we'll take and why, paired with one fixed quote. You know up front precisely what we build, what it costs and when it's done — no open ends, no hourly billing, no surprises afterwards. And getting that blueprint is completely free, no obligation.
- 03 Phase 3 Prototype in days
Build, test & deploy
Then we build, in short iterations. You see a working prototype in days and a finished product in weeks. We work on a modern, AI-native and secure stack — with data protection and GDPR in mind from day one.
- 04 Phase 4 100% your code
Implement & optimise
We launch, hand over the full codebase and keep improving on your terms. You get 100% ownership of the code we write — no lock-in, no licensing games. Hosting and maintenance are optional, never required.
What you always get
Fixed price
Agreed up front, never an open end.
100% code ownership
Your code, fully yours, no lock-in.
Live in weeks
Prototypes in days, finished in weeks.
Modern & secure
A scalable stack that always integrates with the latest tech. Secured by our in-house cybersecurity experts.
Tools & tech
We build on the technology that fits you best. Already working with a certain stack — whether that's .NET, PHP or something else — we simply build on it. Starting fresh? We draw on years of experience to pick the technology that's strongest for your situation. No forced migrations, no tech for tech's sake.

Frequently asked questions
Which platform do you pick: Shopify or custom?
It depends on where you are. For most shops Shopify is the fastest and cheapest start, and it scales a long way. Need special logic, a custom checkout or heavy integrations? Then we go headless or build custom on top of a commerce engine. We choose based on your volume and your roadmap, not on what we happen to like building.
Can you integrate with bol.com and Amazon?
Yes. We connect marketplaces like bol.com and Amazon through their APIs, so orders, stock and fees land in one place instead of in separate portals. For an e-commerce scale-up we brought the channel split across Shopify, Amazon and bol.com into one dashboard, including monitoring that warns you when a feed stops.
What does ecommerce development cost?
We work with a fixed price agreed up front, no open-ended bill. The price depends on the platform, the number of integrations (marketplaces, payment, warehouse) and whether you want the numbers behind it automated too. After a short talk about your situation we give you a concrete figure, not a vague hourly rate that can go any direction.
Will the webshop grow with me as I sell more?
That's what we build for. We pick a platform that scales and keep the integrations stable with validation, retry logic and source-health monitoring. At the e-commerce scale-up the whole system ran on data pipelines that process orders, refunds, fees and stock continuously, even as volume climbs. Your shop won't choke at your first peak.
Do you also connect my payment provider and warehouse?
Yes, that's a core part. We plug your payment provider and your warehouse or WMS into the shop, with validation and retry logic so a missed payment status or stock that won't sync doesn't slip past unnoticed. Source-health monitoring tells you when an integration stops, instead of you hearing it from a customer after the fact.
Who owns the webshop once it's done?
You do. You get 100% ownership of the source code, no lock-in and no hidden dependency on us. You can carry on yourself, bring in another party or stay with us, that's your choice and not something the build locks you into.
