How do I add a vendor to my purchase order?

Last updated: March 21, 2026

Every purchase order in InvoiceOwl is tied to a vendor. Here is how to add or change the vendor:

When creating a new purchase order:

Click Purchase Orders in the left sidebar.
Click the New Purchase Order button.
The first step asks you to select a vendor. Use the search box to find an existing vendor by name or company.
Click on the vendor to select them. A draft purchase order is created automatically and you move to the full form.
If the vendor does not exist yet, click + Add new vendor at the bottom of the list to create one without leaving the page.

To change the vendor on an existing purchase order:

Open the purchase order and click the Edit button in the top right corner.
In the edit form, find the Vendor section near the top. It shows the currently selected vendor.
Click the Change button next to the vendor name.
A dialog opens where you can search for and select a different vendor, or click New to create one.

On the Mobile App

When creating a new purchase order:

Tap the More tab, then tap Purchase Orders, then tap the + button. You can also tap the center + button and choose Purchase Order.
A vendor selector appears first. Search by name or company and tap the vendor to select them.
You can skip vendor selection to create a purchase order without assigning a vendor.
If the vendor does not exist yet, tap Add New Vendor to create one without leaving the screen.
