Before sending records to QuickBooks, Sumac retrieves QuickBooks account IDs by sending account codes from Sumac and receiving the corresponding IDs from QuickBooks. If this process fails, the entire export operation is terminated, preventing any errors in QuickBooks.

For QuickBooks Online, Sumac sends records individually. Successful records receive transaction IDs, while failed records do not. A summary message shows the number of successful and failed records.

For QuickBooks Desktop, Sumac sends all transactions in a single batch. Successful transactions receive IDs, while failed ones do not, and an error message is provided for any failures.

In both versions, a terminal error (e.g., dropped connection) may occur, halting the process. An error message will explain the issue, and transaction IDs will indicate which records succeeded or failed.
