We are using OSS-Integrators for our CRM, Customer Service and Accounting projects. We are really happy with the products and the service. The support is also great. The OSS-Integrators team is working hard to improve the products, so I would say that it is the best option. I would like to see the product becoming more flexible. Also, the price of the products is a little expensive. I would also like to see more OSS-Integrators partners worldwide. We are solving our issues with CRM, Accounting and Customer Service.
