Core allows you to integrate your data with QuickBooks® Online (by Intuit).
You can check out the detailed table-level and field-level data mappings between Core and QuickBooks Online in the attached document. These tables show the flow of data in both directions—from Core to QuickBooks Online and vice versa. Be sure to look at the arrows for the data flow direction. These tables help you understand what data transfers between the two programs and how it can be adjusted in different situations. Whether it flows in one direction or the other (or both) depends on your sync settings. Check the Core Help for details.
