Shopware/Sylius Plugin Development
& Customization

Power-up Your eCommerce With The Plugins Developed For Growth

During dozens of Shopware and Sylius platform implementations, we had to face the issue of creating and developing lots of custom, bespoke functionalities. In addition, every single project requires different functions and configurations – so we must consider each of them individually.

Bearing in mind how much of them we have already released, we decided to distinguish the Shopware and Sylius plugin development as another offered service.

Most of our plugins are open-source so that the whole community can develop them. Many different projects use our Sylius plugins to extend functionalities without the need to reinvent the wheel. What are the benefits of this approach for our clients?

  • Promotion of the provided services (e.g. payment gateway)
  • Increasing competition by having integration with a leading growing eCommerce platform.
  • Plugin development and maintenance supported by the worldwide community
  • Developing brand and/or service recognition
  • Getting to know the Sylius/Shopware ecosystem

How do we do Shopware and Sylius plugins development?

1. We create MVP (prototype) in constant contact with the client, minimizing the time spent on solving potential problems.
2. We rely on the guidelines prepared by the creators of Sylius.
3. We care about the high quality of the source code, which enables its easier maintenance and expansion with new functions in the future.
4. Each project is equipped with automatic tests that minimize the risk of damage to already operating parts of the project.
6. We provide a test environment on our own infrastructure, which allows for ongoing evaluation of implemented functions and independence of the development process.

7*. (If the clients agree). The plugin will be open-source and available on our GitHub so that the community may continue to develop it.
