Thriving Aid
I recommend Maciej Jarzyna and the whole team in the implementation of CRM :) Maciej showed us how to use the tool and get the most out of it. He was patient, thorough and helpful, and answered all our questions. If, like us ( funandplay.pl ), you are just starting out with CRM and have little knowledge of working with such a tool, it is worth learning from someone who knows and will know what will work for you, when you yourself may not know it. If you take action with Sellwise in the process of CRM implementation then be sure to ask for Maciek :) You will thank us for it :) Maciej Chojnacki www.funandplay.pl www.jaju.pl

Implementing the new CRM at a high level
We have been working with SellWise for almost a year now. The company has shown great professionalism at every stage of the implementation of the new CRM system. Mr. Maciej Jarzyna carefully analyzed our needs and tailored solutions that systematized and streamlined sales processes in our niche company, while the system itself needed to be tailored for the specific narrow water and sewer market. In conclusion, I would recommend SellWise with a clear conscience to other companies looking for a reliable CRM implementation.
