@Sandyman, You can try attached SDF file. this is based custom package delivery system with restaurant and Delivery department . All you need to do is add your menu and customization etc…
http://sambapos.org/wiki/doku.php/en/custom_package_delivery_system
I have tested attached SDF file in latest version 4.1.32.
SambaPOS4_delivery package.zip (158.3 KB)
To test the attached SDF file.
Rename your current SDF file to say SambaPOS4_old then extract attached zip file and place the SDF file (SambaPOS4) into the folder.
I would recommend you do it your self that way you will have sufficient knowledge and control
I hope this helps!!!
