Looking for an experienced php developer to create a multi vendor solution for the prestashop v1.3.2 platform.

Please find the website specs below.

FRONT END >
* Customer Notification of Separate Vendor Billing
On checkout, a Customer is given a DETAILED invoice that shows not only totals, taxes, and shipping, but in addition the name of each company he/she purchased products from individually.

* Multi-Vendor Customer Order Tracking
After placing an order a customer can log into the order tracking system, and get a complete breakdown of products purchased from separate vendors, including such information as individual tracking numbers for products as well as the status of each item ordered from each vendor.

* Themes Selection
Individual vendor has the ability to present their own theme based on their required design.

BACK END >

* Administration
All administrators are given password level access and control of the shopping cart software, including site design, color and button management, as well as the ability to edit and/or delete any product created by any vendor. In addition, administrators have the capability to override payment methods specified by each vendor, can set shipping options for each vendor and also have full control of the product category structure.

* Multi Level Vendor Password Management
Administrators of can create passwords for newly added vendors and restrict vendor to only see and/or edit his/her own products. Furthermore, administrators can also assign user name and passwords to other administrators.

* Vendor Specific Product Data Entry Screen
A secured user name and password allows each Vendor to create and manage his/her own product inventory. Once logged in, the system automatically recognizes and allows a vendor to see its products, and quickly enter new ones using the standard data entry screen. The Administrator can define if the products published by a specific vendor appear directly in the storefront, or in a screening area for the Administrator to select.

* Order Splitting For Fulfillment and Payment
After a customer places an order, shopping mall system splits the invoice on the basis of products ordered from each vendor. Based on the portion of the products in the given invoice, each vendor automatically charges the due amount customer. A charge will then be made to the customer on behalf of the vendor via vendor specific automated merchant account. A separate invoice will be sent to each vendor showing what items they have been paid for and who, what, when, and where they need to deliver the product to.

ALso will be able to see ALL INVOICES ALL THE TIME FROM ALL VENDORS, and could base their commission on this. The Administrator has the option to override payment methods set by specific vendors and collect order payments directly from the storefront.

* Vendor Specific Invoice Management and Tracking
Each participating vendor gets an INVOICE MANAGEMENT area that shows NEW ORDERS, ORDERS IN PROGRESS, SHIPPED ORDERS, CANCELED ORDERS, AND COMPLETED ORDERS. In addition, Vendors can also search their entire invoice history by a number of different fields. Each vendor is able to open any invoice and insert customer notes, shipping and tracking information, or change the status of an order.

* Vendor Specific Real Time Sales Reporting
Each vendor has his/her own sales reporting module that shows the amount of sales made during different time periods. Vendor specific sales figures shows OVERALL sales, sales By MONTH, By DATE Range, or in terms of their best selling products. eCommerce Solution would have the EXACT SAME REPORTING FEATURES except that would be global.

* Vendor Specific ASCII/CSV File Import
Online mall solution facilitates the need of importing products into the shopping cart system via a CSV (comma delimited format). One specific file format is adhered to for this import to occur. This format should be exact and provided in advance to the customer creating the import file.

* Inventory Tracking for Vendors
All vendors can set the amount of inventory available for a specific product, and also set the warning level at which they wish to be notified about the imminent stock depletion. For this functionality to be active, a vendor should activate the inventory display option to ‘Item Count’ for that particular product in the ‘online store product editor page.’

* Real Time and Custom Shipping Calculation
Storefront can use real time shipping information provided by UPS and USPS to calculate the total shipping prices based on speed of delivery, destination zip code, and weight, as well as custom shipping options based on order weight or price.

* Tax and Shipping
Equipped to handle state and local taxes, shipping cost for each individual vendor. Vendors can manage their own shipping cost and taxes.

*Create Export File

This feature is used to create csv (comma separated values) files for Data Export for individual vendors or the entire product data by super admin.

* Admin Panel - Export: products, customers and invoices. The exported files are named products_export.csv, customers_export.csv and invoices_export.csv. A link to these files is displayed once the data is exported successfully. The invoices_export file can be generated for different order statuses, and also with an option to include the ‘order item lists’.

* Vendor Panel -export:products and invoices. The exported files are named products_export.csv and invoices_export.csv. A link to these files is displayed once the data is exported successfully. These files are stored in the vendor’s folder (this folder will be created with the vendors user name when the vendor first enters the site) in the products directory. The invoices_export file can be generated for different order statuses, and also with an option to include the ‘order item lists’. These files in the vendor side contain only the vendor specific orders.

*Extract Data

This feature is used to export/download data from the category including subcategories, and mfg tables that include numbers and codes for generating the import file, which will be used to upload/import bulk of product information from a csv file to the store database. This feature needs to be available both in the admin and vendor panels. A link to these files will be displayed on successful export.

*Upload Products

This feature is used to import product information from a pre-defined file format (csv file with the column heading as the first row/line) for data upload.

The first row in the file should be the column headings. The information specific to a particular product should be entered in one row (fields in the same order separated by comma) and there is no limit for the number of rows. For inserting a new product, the ProductID should be left blank.

When the vendors upload their products, they can either specify their VendorID or can leave it blank - the system will insert the VendorID automatically.

When the admin upload the products, he/she should specify the VendorID. The system will generate an error file with the failed data and the error description. The file name is ‘Product_error.txt’. A link to this file will be displayed if an error occurs during the upload process.

*Payment and Shipping

When the admin adds a new vendor, he/she should also add custom and/or online payment methods and shipping methods. Custom payment methods can be added using the custom payment manager and shipping methods in the shipping manager of the admin panel. Please make sure that at least one payment method and shipping method exists before a product is added for that vendor.

Admin has the ability to choose between an integrated single check out cart for all vendors or individualised check out system for each vendors.
