Uninstalling PosiGiving
You will need to uninstall PosiGiving products in the reverse order of installation, as follows:

ProntoPlus
ProntoGiving

Please note you may experience errors in the uninstall process due to customisations done on top of the standard PosiGiving configuration, or issues due to Salesforce errors.
