Does anyone have any best practice or recommendations on how best to go-live with Cash Management in Fusion (currently 20C but the questions fusion generally)? We are close to implementing this module in our live environment but are unsure on how best to begin using this over current in-house solutions.

We are aware of the  'Reconciliation Start Date' flags on the bank account itself but there will be a period of time where there are differences between what is in the system and what is on the statement i.e. people paying aged debt  long after the AR invoice was raised, returned/void payments in AP or invoices been raised and paid either side of the 'start date' in AP.
