You can create a Purchase order and link it directly to a project, accounts625.
While QuickBooks Online doesn't allow you to assign a supplier to an estimate, you can use a Purchase Order instead to record supplier-related pricing.
A Purchase Order can even function as a quote, as it allows you to document the cost of products or services. Similar to estimates, it provides an initial breakdown of pricing and forms the foundation for potential transactions between you and your supplier.
Here's how to record and link a purchase order to a project:
- Click the + Create icon and select Purchase Order.
- Select a Supplier from the dropdown button.
- Choose a Category.
- Enter the Amount and select the Project.

- Optionally, enter a Memo such as "Supplier Quotes."
- Click Save and close.
Once your supplier provides the final bill, you can edit the Purchase order and convert or add it into a bill.
