What we build for Dutch businesses

Custom software and web builds for growing teams

Custom websites

Fast, structured websites for service firms, studios, and B2B teams. Built with strong content architecture, clear calls to action, and the technical flexibility to support future features.

Client portals

Secure portals for clients, partners, or members with login, document access, project status, forms, and account-specific content. Designed to cut inbox traffic and centralise key information.

Integrations and automation

Connect your site or system to CRM, ERP, email, payment, scheduling, and reporting tools. We reduce duplicate entry and keep data moving between the systems you already use.

Internal dashboards

Dashboards for operations, sales, and management that show live data in one place. Useful for tracking leads, jobs, tasks, content, or support requests without spreadsheet work.

A delivery process your team can follow

1

Discovery and scope

We map your goals, users, systems, and constraints, then define a realistic build plan.

2

Structure and prototype

We turn the scope into page layouts, user flows, and interface logic before development starts.

3

Build and integrate

We develop the site or software, connect the required tools, and test the key paths.

4

Launch and support

We go live, fix any final issues, and provide ongoing help if you want continued maintenance.

Projects built around real workflows

“Izocode replaced three separate tools with one portal that our team actually uses. The project stayed organised, and the handover was clear.”
Sanne de Vries — Operations Manager, Utrecht
“They understood our business model quickly and built the right integrations without bloated features. Delivery felt disciplined from start to finish.”
Mark Jansen — Founder, Amsterdam
“We needed a website that could support lead intake and reporting. Izocode delivered a clean build and documented everything properly.”
Nina Bakker — Marketing Lead, Rotterdam

Common questions before we start

How do you calculate the cost of a custom web application?

We estimate projects based on an hourly rate of €85. After discussing your specific requirements, we provide a fixed scope proposal detailing the required development sprints. A basic MVP typically starts at €12,000, while complex platforms with external API integrations require a larger custom budget.

What is the typical timeline for delivering a custom WordPress or WooCommerce website?

A standard WooCommerce shop takes six to ten weeks from design to launch. We split this into separate weekly milestones: wireframes, UI design, frontend development, and backend configuration. You will receive access to a staging environment in week four to review our active work progress.

What does your post-launch support look like, and is there an SLA?

We offer three Support Level Agreements starting at €250 per month. Our basic SLA guarantees a quick response time for critical bugs. It includes six hours of monthly maintenance for security updates, plugin patches, server monitoring, and small layout adjustments on your live web site.

Which programming languages and frameworks do you use for custom software?

We build scalable applications using Laravel and Node.js for backend systems, paired with React or Vue.js on the frontend. For mobile apps, we use React Native. We write clean, documented code and host staging and production builds securely on AWS or European DigitalOcean cloud servers.

How will we communicate during the development phase and track project progress?

We use ClickUp for task tracking and Slack for daily communication. You will have a dedicated project manager fluent in Dutch and English. Every two weeks, we host a Microsoft Teams demo to show working software, gather feedback, and plan goals for the next sprint.

Who owns the source code and intellectual property after the project is completed?

Upon full payment of the final invoice, complete intellectual property rights and source code ownership transfer directly to your company. We host everything in your private GitHub repository, and we do not charge any recurring proprietary license fees for the custom software we actively build.
