1. Click the + New button.
2. Select Purchase Order.
3. From the Vendor ▼ drop-down menu, select or add a vendor.
4. If you are shipping a product directly to a customer, select the Ship To ▼ drop-down menu and choose the customer.
5. If you're using custom fields, fill them in as needed.
6. In the Category details and/or Item details section, enter the purchases.
7. Select Save and close to complete the entry.
