Customer Testimonials



"We started to build  a dedicated team in Lviv together with ABTO Software  around nearly 3 years now. As a product vendor we have to rely on resources that can build up their knowledge about our products on a long term basis. ABTO was able to provide us this services on a long-term relation. It always was and is an excellent work together and we look forward for many years more. Because I visited the company in Lviv many times I can say ABTO always is doing the best to give the people a good working atmosphere. Had really good team events there and the employees have a lot of fringe benefits in ABTO. I definitely can recommend ABTO for a nearshore center!"
