In QuickBooks Online (QBO), you can only import the following information: Bank Data, Customers, Suppliers, Chart of Accounts, Products and Services, Invoices, Bills, and Journal Entries. For transactions like purchase orders, you'll want to enter them manually.
To create a purchase in QBO:
- Select Purchase order under Suppliers from the Plus (+) icon.
- Fill in the necessary information.
- Click on Save or Save and close to record the transaction. Or, tap on Save and new if you wish to enter a new purchaser order.
