Professionel, skilled and serviceminded
We have been using our Bitrix24 platform for around 5 years and have switched Bitrix partner to Selleris. I must say, that despite we are quite into the platform – we have experienced a high level af service and skilled staff from Selleris. The result has been, that our platform today is even better, more implemented in the organization – yes general more valued. Thanks for great assistance team Selleris, we would not have been able to do this without you. Big recommendation from us.

Great experience with Selleris
I had a great experience working with Selleris. They helped me plan and set up Bitrix24 for my non-commerce organization. This included building our website, which was done smoothly and professionally. The team was very supportive, answering all my questions and guiding me through each step. I’m happy with the result and would recommend Selleris to anyone looking for help with Bitrix24.
