What data is synced between Pleo and Quickbooks Online?
"Categories" in Pleo reflect your chart of account names in Quickbooks. When you set up your categories after enabling the integration, the drop-down menu in Pleo will automatically reflect your account names (either numerical or textual) in Quickbooks. That said, you will need to give the specific category (account number) a name in Pleo that will be easy for employees to understand when adding details to their purchases.
"Tags" in Pleo reflect your classes and projects in Quickbooks.
