Point of sale

Can you add a point of sale for restaurant like cashier screen quick invoice and touch screen

Manager is an Accounting program not a restaurant POS. There are much better products you can use even some open source ones (search the Internet). If you search this forum for restaurant you would notice that it is advised to use a seperate POS and just import the totals of the transactions for accounting purposes in Manager.

Welcome to the forum @ahmed_awed

There are no plans to implement POS features in Manager yet. This has been discussed multiple times before, so feel free to browse the forum and read the lengthy discussions in this regard.
