Create Beginning Balances
Create one journal entry using the marked up Trial Balance from your old accounting system. Use the period/month PRIOR and enter the ending balances as a debit or credit. The journal entry must be in balance in order to post/save the record.
Print the Trial Balance in Orion for the Go-live period. The beginning balances on this report should match the ending balances from the old accounting system.
For audit purposes, keep copies of all working documents used for creating the beginning balances.
