We worked with RMF (https://www.reversefunding.com) from 2015 and during all this time we help them to build all the business process inside Netsuite (custom records/forms/scripts) and also integrate with in-house software (Restlet-WebServices) and Salesforce integration (inbound-outbound). Also we have implemented Mobile app to take picture, process information and send this information to Netsuite/Salesforce.
