ERP/CRM With POS Barcode Module

Hello, I am a software programmer and i want a CRM/ERP web application that will allow simple POS(barcode enabled for scanning barcode of some items) for the front store of my client. The application will have the admin module that allows admin to create, edit and delete items(creating items means generating barcode for each item and assigning prices and other items properties and also scan the same barcode for quick sale at the front office). Note that the web application should have the features of CRM/ERP but the POS part is there because the office has front desk like sales person that attends to instant customers order request. There should be a report generation for daily sales, weekly sales, monthly sales, Trial Balance & Balance Sheet reports as well and also there should be at least 3 levels of user login(accountant who only sees the account part in the application, clerk who only sees the POS part of the application and an admin who sees all modules in the application) . The primary service of the company are categorised in three phases: *******SALES(Front desk) the following are the items for sale : Tiles, Electrical, Interior, Paint, Sanitary, Kitchen, Doors, Construction Materials, Tools, Special Projects *******MANUFACTURING : the following are the items the company produces by itself Doors, Kitchen *******TRAINING : this module should just take a simple bio-data of candidates that come in for manufacturing lectures. Basic candidate details like Name, Address, DOB, e.t.c..... are collected here. There must be a demo for me to be sure this web application works as expected. The application should use pure PHP MySQL JQuery Responsive design and it should be easy to use. Note: I am a programmer and all i want is a ready made demo project, the items(Tiles, Electrical, Interior, Paint, Sanitary, Kitchen, Doors, Construction Materials, Tools, Special Projects ) are there for data testing. If you have an existing project that can be modified to suit the need, please kindly let's see it. Regards, Olammie
