It must have easy intuition, speed, combined with a photographic product catalog, or rather it must be the photo that I have to choose the product (then the administrator will choose the location of the product where to place it in the back office). Example : 1) I open the application with an Id, 2) I open a customer card (combined with a short name), 3) I need to have the opportunity to enter and exit multiple catalogs, 4) I open the photographic catalog press on the photo asking me the quantity and I charge the product, and so with other products .... 5) Possibility of: sending, modifying order, notes for the warehouseman, etc. 6) Finally, close the order and ship it to the warehouse. The administrator can give access and limitations to employees who use the application such as: view orders, edit and print them (with the possibility to have a summary with the order partial and total order to have a pro- Bill form is printable and visibly visible to video) but not to modify the quantities of merchandise for reorder to suppliers, which can only be done by the administrator with a password.
