osCommerce Complete Admin Order Entry/Edit

osCommerce Project: Complete Admin Order Entry/Editing System Project Goals: Provide user friendly order entry/editing system for site operator. This system will be used by site operators to enter orders as they are received over the phone so it must flow nicely in a logical fashion. Any suggestions you have to improve on this concept will be appreciated. Point of sale? I need this system to be extremely simple and fast to operate...as easy as a point of sale system. I looked at [login to view URL],3016 PHP Point of Sale. I like the idea of a "stand alone" point of sale interface for this function, but it doesn't fully integrate with osCommerce to show attributes, enter/edit customers, edit orders, etc. Related Contributions Currently Installed: I have a mixture of the working components of these two contributions. [login to view URL],1435 [login to view URL],1589 Custom Modification: California Sales Tax by Zip Summary: If State = CA get tax from CA tax table by zip else normal tax function. Required Functions: 1. Improve on Admin product selection system (1435/1589) to make extremely fast and efficient. > Must be simple to navigate through 6,000+ products. > Product search feature enabled. > Maybe a list of last 25 products sold so most frequently used products are easily entered. 2. Enable Product Attributes in Admin product selection. 3. Enable all shipping and payment modules in Admin order entry. > Current Admin Order Editor only provides a box to type in the payment module. > I need a system that lists the modules just like the customer side so Admin can quickly select module and caluculation is made for them. 4. One page checkout with shipping & payment modules displayed. ** If this works well, would like to provide one page checkout for public side too as add-on to this project. 5. Display normal prices and enable admin to enter custom price and/or discounts. I have a highly modified osCommerce installation To aid in keeping all the modifications organized some additional commenting will be required. Please consider these additional requirements when bidding. 1. List of all modified/added files. 2. Commenting all changes with // MOD-NSOE Start/End which designates Net Step Order Entry. You may add your company name to the comment if you want // MOD-NSOE - YourCompany Single line changes will be /* MOD-NSOE */ to speed things up a bit. 3. TXT files with all mySQL statements must be sent to me for installation. I'll be available constantly, so this should not cause a delay. 4. Admin Access Your own Working/Testing Environment: I will make a copy of my site for you to FTP directly to for installation and testing to ensure the modification works properly with the other installed modifications. You will be able to test the system with a copy my real data so any issues with managing thousands of products can be addressed.
