Premier Systems A.S.

Premiere Systems A.S. is a accounting windows application, developed especially for small and medium businesses.

Our team was asked to create an online version of the software. We decided to start only with few features, such as creating an online invoice.

We have learned the details thoroughly, added a little bit of magic – and released first online version of the software.

Responsive application

Web application could be easily opened with your tablets, phones etc.
Online application works faster – we used a speed perfomance optimization
technologies like Google Pagespeed, SVG graphics, image sprites and caching engine.

Improved usability

We have not only copied some windows app features online, we have improved the usability of the process.
Now the application could be easily used by both – experienced users and beginners.

  • New design
  • User friendly
  • Easy to use
  • Online version

How did we do this?

Technologies we used:

  • Front-End technologies – Backbone.js, Require.js and Underscore.js
  • Back-End technologies – PHP, Laravel, PayPal SDK, JWT authorisation
    and synchronization with Windows applications

Windows App Integration

The hardest part of the process was integration. We have integrated application with an old windows software with complex artitechture, created API for authorisation, file exange process, invoice synchronisation process. Now the invoice created in the online version would appear in your offline software.


Our team has developed a set of UI/UX elements that are necessary for work with the application.
