Good morning @Simmerton and welcome ti the ODK community forum. Don't hesitate to take some time to introduce yourself here .
Many ways to load data into QGIS (and ArcGis I guess).
You should take a look at the QRealTime from @shiva_Reddy
I never used ArcGis and I do not know its capabilities, but I guss it could connect to a PostGIS database so you could also store ODK data into PostGIS and serve views to Both QGIS/ArcGIS. It depends on the complexity of the information system in place and needs of the organization you help.
