Yes. For clients who enter the survey themselves, or service providers who enter data completed from paper surveys; if for whatever reason, a person entering a survey on the OPOC website needs to stop at any point, and return to it later is possible. The survey automatically saves the responses after each page.  So if a client gets halfway through and stops, they can come back later and their previous answers will be saved.  They should enter the same OPOC key to complete the survey.  If the client knows in advance that it will take more than one sitting, they can set up a password in advance to access it again later.
