Very often, we are approached for the full implementation of CRM after such "settings". Most often, they are carried out by contractors who do not have the proper experience in working with complex business processes and who do not fully understand the functionality of CRM.
An unscrupulous "integrator" sells licenses, and does "setup" just for show. As a result, the client receives a simply non-working product. We had a case when, after such a "setup", a customer contacted us, who suffered losses of over $ 8,000 in just a month of working in such a system.
