Does OpenCRX have webforms where potential clients can enter their info and submit to the system,
Are there a backend for the customer to log into and view work progress?
There are no such web forms in the standard distribution of openCRX. However, they can be added easily (by a software developer). The openCRX sample project contains a 'Store' frontend which shows how such a client / customer front-end can be implemented. For more information see https://sourceforge.net/p/opencrx/wiki/Sdk212.CustomProject/.
