This is an optional step
To simplify the administration and tracking of petty cash activity, you can set up Petty Cash Accounts to record money in and out transactions.
This can be done using the Accounts Import Template (See Setup Chart of Accounts) or by manually adding a Petty Cash Account.
Banking>Petty Cash Accounts + (New Petty Cash Account)
You can add the Opening Balance at any time. We suggest you do this when you have all the Setup completed and you have completed all data migration steps including import of open transactions and other opening balances.
