Credit Application Processing (CAP) is a web based credit evaluation system. CAP provides Finance and Leasing Companies with the ability to quickly assess the worthiness of an applicant applying for a loan or a lease. The System is equipped with strong workflow management, integrated link to Credit Rating Agencies, automated point scoring strategy for automatic approval/rejection/referral. CAP is seamlessly integrated with POS but it can also be customized to link to any third party Point of Sale System (epos).

Point of Sale is a web-based credit origination system for financing and leasing companies. This module can be implemented as a stand-alone or merged together with Credit Application Processing (CAP) to create a comprehensive credit origination and evaluation system. POS and CAP can also be easily integrated with Credit Management System (CMS) to create an end-to-end Retail Finance system.

Lead to Quotation is a .Net WCF service based module that dumb third partys leads information into Point of Sale Database and then that dumbed lead converts into Quotation in POS for further loan or lease process.

I had developed Public APIs for the Integration of current system with third party i.e. NPOS is the third party system that accessing different modules like Application, Cesar, Login, Document Management, Diary, and Quotation. Public API expose to the different clients (China,Singapore,Malaysia)as well and they are authenticated using OAuth2.0.Every client has Client Credentials (its client id and secret id)on the behalf of these credentials they are accessing the Public APIs.The whole Financing System has been exposed using Public APIs for clients Daimler Mercedes Benz China.
