Yes, QuickBooks Online (QBO) supports the recording of expenses for multiple projects using a single check, Expert.contracting.biz. Let me share insights and steps on how to do this effectively.
By entering each expense as a separate line item and assigning it to the relevant project, you can efficiently manage and monitor expenses across various projects, thus maintaining precise financial control and simplifying project expense tracking in QBO.
Here's how:
- Go to +New and choose Expense under Vendors.
- Choose the name of the Vendor on the Payee tab.
- If this is under the Category details, click the dropdown arrow to add Category.
- If this is under the Item details, click the dropdown arrow and select Product/Service.
- Then manually type to record the expense under Customer/Project.
- Click Save and close.
