When viewing the table plan you can add an order straight to any table by pressing on the table and selecting 'Add items'.
If the table already has a tab linked to it, the items will be added to that tab. If the table is a free table a new tab will be created with the same name as the table.
This will bring up the EPOS screen with a message at the top of the order view signalling which tab the order is for.
Add items to your order as usual and press 'ADD TO TAB' once done, which will take you to the tab on the summary screen.
