Public accounting site: custom Wordpress solution with a calculator feature
  • Intuitive responsive design
  • Extensive customization of WP theme
  • User-friendly easy-to-use online calculator



Our French client, Adezio, specializes in accounting, audit, consulting and social law. They requested a modern user-friendly WordPress-based website to facilitate and promote their services.

The challenge

The core of the logic for a new Adezio website had to be an accounting calculator, helping people to see the cost of the services. The initial requirements included:

  • Creating a responsive public accounting site on top of WordPress CMS.
  • Developing and attaching a user-friendly easy-to-use online calculator.
  • Significant customization in addition to the selected WP theme.

During the project we ran into some difficulties of engaging in a dialogue with the enterprise, due to its multi-vectoral and cross-cultural character. In particular, the client’s choice of a fixed-price model in combination with incomplete initial requirements presented a major challenge.

Due to the scarcity of project details at the start and therefore evolving requirements, the most challenging part was providing an adequate estimation. The urgency of the project prompted our decision to start with an incomplete set of design mockups. So the first solutions had to be made intuitively, based solely on sketches. All of that made the pre-production stage extremely complicated and increased the project’s risks despite the apparent simplicity of the task.



We began with the design’s technical review. Our WP developer had a demanding task of aligning the heavily customised design to the logic of the chosen CMS. Working in close collaboration with an external UI designer, we significantly improved the initial sketches, keeping the project’s spirit.

Our basic task was to develop and design a user-friendly calculator that would enable Adezio clients to get quick estimates of the services they sought. The widget is initiated via the ‘Get a Quote’ button on the homepage and opens a four-step guide. This allows for specifying an end-user’s business and the type of assistance needed by simply switching through a number of selectors and eventually filling out a form. We also elaborated the calculator’s unique design.

Another requirement was to put special emphasis on explaining the collaboration process with the enterprise. We used a timeline metaphor on the homepage.

The rest of the web site represents marketing collateral related to the client’s services as well as relevant documentary resources.

After testing, we deployed the product on the client’s server (OVH).
