You ask some excellent questions. We have relied on Concur for access of past reports. It's been handy and helpful to have that access back to the year we started on Concur (2006). But I have feared that Concur would archive older records at some point.

We've already been impacted by the recent change where Concur instantly removes a lot of data from the profile when an employee leaves. We need some of the data they're removing in order to function.

The ability to change providors is also important. We don't want to be held hostage by data records.

We are working on setting up an API and that may help us store our own history in a retrievable format.
