It is best practice to always keep the base case scenario clear of any actions related to collection, payments and finance. This ensures the base case is reflective of the live data being pulled from your accounting software.
It is best to "add a scenario" which will duplicate from the 'base case' and then take actions related to collections and payments by adjusting the Anticipated Payment Dates (APDs).
Important to note - changing APD's in the scenarios override the payment dates that are updated from Xero. If you have updated payment dates in your accounting software, it will be reflected in Skippr if you have the "Base Case" clean of any payment date adjustments.
