To disable GST setting, all you need to do is go to System Configuration >> GST >> Untick the Enable GST as per displayed in the image below.
Remember to click SAVE (located on the top right of the screen). Make sure your Xilnex does not have sync issue when you are performing such action.
Best to request all the outlet’s to restart their Xilnex to ensure that they received the latest setting that has been configured by your side.
Extra Note, once the GST setting has been disabled, automatically, our system will take in 0% as GST rate, instead of the standard GST rate that has been pre-set on the system earlier. This setting will affect all outlet under the same Xilnex account.
