Submitting individual transactions
If the Sync to Accounting app’s processing mode is set to “Manual” (default), in order to create a record in your QuickBooks Online account, each transaction must be submitted for processing. You can prepare them for processing either by selecting a single or multiple transactions using the check mark box beside each. You may then submit the records to accounting system by clicking on “Submit” button.
If the Sync to Accounting app’s processing mode is set to “Automated” then the system will automatically submit new transactions for processing on a daily schedule, once per day.
When a transaction is successfully submitted and recorded into your QuickBooks Online accounting system – a green check mark will appear. It will not be possible to process it again and the check mark cannot be removed. This protects against double posting transactions.
