To ensure that a married couple can see their giving combined in One Church Software, you should adjust their Family Settings in the "Giving" tab of their profile.
Go to the search bar at the upper right-hand of the page and type in and select the appropriate name of one of the individuals. Click on the "Giving" tab within their profile, choose on the "edit section" button, and select "Family Settings" to adjust the settings for combined statements. Click on "Save" to apply the changes.
Once these steps are completed, both individuals should be able to view a single combined giving statement reflecting their joint contributions.
