This is a work for a client of us.
We need two .asp or .php files for an oscommerce installation that make this:
1) Import data from a file in a FTP address to the MySQL of OsCommerce. (products, clients, categories, subcategories and perhaps 3 more)
The file to import is generated by a Desktop Application in raw data.
2) Export data of orders in OsCommerce to a file in the same FTP address as above.
The file format to export is the used by a Desktop Application.
There is development already made from the importing option (an ASP file is made yet) but need to test and fix.
There are instructions explaining the format of the files (now in spanish, but we can translate the needed), and we can talk with the software developers of the Desktop Application to solve doubts.
The project will be paid after test it succesfully in the web in production.
This is our first project here, but we have more coming.
