We have a online store that uses a web assist shopping cart system.
We are opening a store and I plan to use the same backend as a POS system.
I plan to create 1 page though for store employees to key in item #'s and take Payment information.
The project I need help with though is when a product ID is entered in the form, I need the db to fill in the product name, price, etc. on the form and then tab to the next line. ? I also need a dynamic sales tax and total to update as each item is entered.
I can be reached by phone or email. ? If this is more complex, I'm flexiable on the design.
