CS-Cart 4.x Purchase Order Addon

Hello -

I am looking for a Addon For Cs-Cart which can do the following and I am only looking for experience CS-Cart Developer.

1st Step - When adding products it will ask us for the following
Product Selling Price
Product Cost Price
Our Item Number
Vendor Item Number

And same for variants , as each variants for example black color has a different item number for seller and vendor along with different price .

So if I am adding for example black color it will ask cost price, and selling price and our ITEM Number & Vendor Item Number so when we generate PO It will email the Vendor/Supplier as per my attached email PO .

Step 2 -

Order comes in when he Complete the order like change the status to Shipped or Completed it will then email the Vendor the Purchase Order in same Invoice Format, but in Purchase Order it will use CS-Cart Order Number as Customer ID in Purchase Order and no Customer Telephone and email will show in the PO .

Step 3

We as an admin can search for PO with PO Number, delete the PO and sometime if we have a stock in our facility than even if the product is specified to the Vendor we don't want to notify the Supplier so there must be some option where we can Untick to NOT NOTIFY THE SUPPLIER with PO .

Step 4 / Step -1
I wanted to use CS-Cart Supplier option where when we enter the supplier Information it should ask us to either we want to send that supplier PO or Not.

Step -5
All PO's must be searchable either with Order Number or PO Number and we should be able to paginate the view and also see which product was been sent to the Supplier and the Amount Owed based on Month and Year to the supplier more like reporting purpose so we can track things down like which product is been bought from which supplier and in how much QTY & which product is we buy from which supplier the most .

So in Long Story Short - When I complete the order to complete and ship it will email the supplier generated PO which will look like Invoice but It will have Purchase Order Name instead of Invoice if you want I can also email you the template of what I want to send to the supplier with Good Reporting functionality.
