We have one customer who has been using the tool for about 5 years. They bought it direct and work directly with Prophix for support. Overall they are very happy with the tool. They use it for budgeting and financial reporting. They do not pull budgets back into Sage 100 but rather extract data from 5 companies in Sage back into Prophix on a nightly basis. They pull GL account balances as well as GL detail activity. The data exchange was set up by Prophix using SSIS reading from Sage 100 providex tables via ODBC.
We have been working with them to migrate from Sage 100 to Acumatica. The client was so pleased with Prophix, they didn't want to look for a new solution with an existing integration but rather had us work with Prophix to rebuild the connections via SSIS to Acumatica.
