Tips on performing a bank rec for the bank account balance as of go-live date? Client imported ~2 years worth of summary level, my thought is to create a one line bank statement with the balance as of the go-live date to clear out all of the journals posted for the historic balances. From this point the bank rec process should be handled normally with transactions in NetSuite to reconcile against - I don't see any issues with this process but wanted to see if anyone else has other methods
