RMCS and Projects Contract revenue for Professional services

Summary:

Pls let me know if the integration between RMCS and Project Contract is stabilized and other clients are using the functionality

Content (please ensure you mask any confidential information):

In my past experiences 3-4 yrs back, the integration was not stabilized and there were many issues say. the contract is amended with amount from 100k to 200K those changes would not be updated but saw few updates in new releases.

Pls share your experiences and let me know what is the best practice if project revenue should be used or should be routed through RMCS. The client has multiple sources of revenue and project revenue is only 5% of the business for professional services revenue
