Project Description:
We currently use a purchased, web-based POS system written in PHP with a MySQL database. We have 100% of the source code and the system is meant to be fully customizable.

We would like to add the ability to "Purchase" products from customers.

SCENARIO A: Some costumers will bring in an item specifically to sell to us. We need to be able to purchase the item(s) in the system and then either issue credit in the system for the client to use at a later time for in-store purchases or issue payment in cash right then.

SCENARIO B: Other customers will bring items in for repair (which our current system already handles) and then decide not to repair the item for some reason. We need to move that item to a "Purchase" which then follows the same procedure as above.

SENARIOS A & B: During the "Purchase", the same info from the form currently used "Add New Stock Item" should be used with the exception of "Selling Price". Once we have "Purchased" the item(s), the item needs to added to a new table for "Purchased" until an administrator can review and MOVE to an Inventory Stock Item along with selling price.

Thank you.
