Care2x and WebERP integration

The project is to integrate Care2x & WebERP Open source systems. The high level requirements are. 1) Development of Health-Insurance module in Care2x 2) Development of Billing module in Care2x which will integrate with WebERP 3) Development of a Payroll module (Singapore payroll requirements) in Care2x. Programmers have to demonstrate proof of skills(by performing a task) before contract/agreement could be signed. Task: Create Billing tables in Care2x database (with services/drug, qty, price column, etc). Make it appear in Care2x application as a Billing menu. When the user saves the bill it should appear in WebERP as an Invoice. Bills should be printable & searchable by services, drug, patient number or doctor number. Requirements: 1) The original tables should not be modified, although tables may be added. 2) The extensions should be created as Plug-ins for Care2x. (see Care2x documentation). 3) Try to keep the same theme. 3) The source code will become the property of the payer. 4) Agreement of Non-Disclosure. Best of luck.
