During this workshop we will talk about your strategy and determine the goals of your new website. We will hand sketch the pages, as well as discuss the design direction. This meeting is crucial to collect all the info we need to get started on your project.
WordPress Development
A lot of people associate WordPress with templates, but we never use those. As well as the design, development is fully custom. Our coders use the WordPress platform to build on, ensuring you have an easy to use Content Management System. It is the most used CMS worldwide, and because of it, the stability and security are unrivaled.

Your web agency

From start to finish

Everything we make is 100% custom. We do not use templates and every line of code is written in-house. The process is divided into several phases, and for each phase we have a quality check and approval moment before we move on to the next part.

Kick-off workshop

Once you have chosen us as your web agency, we always start with an inspiring workshop. During this meeting we will go over the goals of your website. Who are your customers? What is their customer journey? What pages do we want them to visit? We do this to get an idea of what the website should look like in general.

When developing a website, you enter a process of working together with our designers, developers and project manager. We work as a team, and we ensure that it is clear what is expected of whom, making sure your beautiful website is quickly delivered.

The initial workshop provides our UX-designers with enough input to make a line sketch of all pages of the website. We call these line sketches wireframes, and they tell us on a very functional level what the website will look like in general. We will always present the wireframes in a meeting, after which you can give feedback. Usually we need one to three rounds to perfect the wireframes, and once they are approved by you, we will enter the exciting phase: The wireframes will be transformed into a stunning design!

Let's start sketching!

Web Design

Wireframes approved? That means we can start designing! But first, we will have to decide what direction to go in. We always start with creating your homepage. Same as in the wireframe phase, we will present the design to you in a meeting, after which there is room for feedback. When the homepage is approved, we will continue designing the rest of the pages. Aren’t you curious what your new website will look like?

The development phase means bringing the design to life. Your new website will be completely converted to digital code, development will be working hard to put it all together. During this process we will keep you updated on our progress. The first version of the website will be installed on a test environment. In this environment we can test all functionalities and user flows extensively. After an initial internal check by us, there is room for you to do your own tests and checks and provide us with your feedback. You can upload now your content while we are working on the finishing touches.
