Creative process supported by industry best practices

01 / Analysis
(Getting to know your problems)

In the first stage, we need to get to know your business and understand the problems you face. We approach each case individually and try to find the best solution tailored to your business. If the case requires it, we will trace the processes physically by visiting you at work.

02 / Project
(We create a common plan)

Whether we are creating a workflow for your warehouse or a new online store. Every collaboration requires a design, brief and roadmap so that we can work smoothly and according to your recommendations. At this stage, we define a strict project framework. This way, you'll know what's going on and the progress of the work from the beginning.

03 / Implementation
(We cyclically deliver values).

The most important part of any project. We do the work for you in sprints of four weeks. Every two weeks we meet and discuss what has been done and what still needs to be done. Depending on the scale of the project, sprint cycles can last as long as several/many months.

04 / Implementation
(We test and investigate)

At the very end of the sprint(s), Tom or Adam will deploy the solution on a test environment prepared by you. After successful testing, we will deploy the solution to production and monitor it in the near term to make sure everything is OK.

05 / Support
(Support and Development)

We will also support you after the implementation of the project. Any dedicated solution, requires special and specialized care. With a flexible range of support plans and a dedicated customer panel, we respond quickly to any reported problem and are available to you even on weekends, if your business requires it. You can read more about our support plans here.

We have been cooperating with Changelog in technical support for integration between sales systems. From the beginning, the cooperation can be described as professional. The gentlemen make every effort to ensure that the quality of support is at the highest level. We also cooperate in the implementation of further system integrations. We can always count on quick response in case of need or occurring problems. In addition, the implementation of patches and solving technical problems is also done at a fast pace, the response time is very short, which facilitates work and helps with further development. We look forward to long-term cooperation at a sustained high level.

We wanted to streamline the work of our store - to better manage e-commerce processes, to maximize the use of available tools and technologies. The Changelog team (formerly DreamTeam) provided a solution created exactly for us, tailored to the specific queries, needs and real capabilities of the company. The implementation of the entire strategy went smoothly and did not reflect on the business at hand. They quickly detected and fixed the main errors that were stopping our operations, while maintaining efficient communication with third parties. I also appreciate that Changelog (formerly DreamTeam) is able to explain quite intricate processes in an understandable way, and its specialists were available to us practically all day.

It is impossible to overestimate the professionalism and commitment that Changelog.co.uk put into creating our website. Their team not only provided us with the perfect tool to present our products to the group, but also understood what our brand is all about. Taking care of the smallest details, they created a site that perfectly reflects our philosophy and aesthetics. Their approach to the project, focus on our needs and perfectionism made the whole process smooth and efficient. Thanks to Changelog.pl, we not only have a functional site, but also a visual gem that sets us apart from the competition. We highly recommend Changelog.pl to any company looking for a professional and reliable partner.

Cooperation with Changelog was very successful. The implementation of the changes in the Sellintegro plug-in was successful and saved us a month of one man's work at a cost of 1/3 of an employee's salary, not to mention the savings and avoided mistakes in the future.No other company wanted to take on this task. For the Changelog team, it was an undemanding challenge. Contact with the Project Manager transparent, factual and precise. Minor childhood diseases of the implemented change removed promptly. Great flexibility in the context of cooperation. If I need some additional functionality that Sellintegro does not offer, I will definitely hit the guys from Changelog first.

Thanks to our cooperation with Changelog, we implemented BaseLinker and integrated SellIntegro to fully meet the needs of our Vilo brand. The implementation was carried out professionally, and the solutions introduced allowed us to automate key processes and eliminate manual tasks. As a result, we saved significant time resources, and the risk of operational errors was completely eliminated. We would also like to emphasize the exceptional commitment of the Changelog team, especially the Support Department (Adam), which stood out for its responsiveness and readiness to act in any situation. The implementation was completed as planned and on time, which further confirms the professionalism of this cooperation. We heartily recommend it!
