Yes.. sort of.
The good news is that we currently do support the functionality for this to be possible, however as a user of the Mobi2Go platform there is no way within your Administrator Dashboard (or Store Settings panel) as there's no user interface available for this to be done.
This will instead need to be done by our development team in the back-end.
If you do require tax/GST-free items on your menu, please contact our Mobi2Go Support team who will raise this with our developers, who will then be able to make your dreams come true. 🚀
