I have a POS application that takes the products from a Joomla/Virtuemart website's database.
What I need you to do is to add the following functionality:
When the store worker is making a sale, he needs to be able to ad an expense that is not on the website, such as "others" and type in the amount, so that this expense will show on that sale and be reflected on the client's ticket, but no new product will be added to the website's catalog.
I am looking for someone with a lot of experience, who can do this really fast and inexpensive. Please PM me with your questions.
