Hi there, @Juma Shop. 

You can add a product to your purchase order in two ways, the first is through the Vendors section, and the second is through the Product and  Services section.

To create a Purchase Order under the Supplier section, please follow these steps:
 

1. Go to the + Create button on the left-hand menu
2. Under the Supplier section, click Purchase Order.
3. Choose a supplier you're creating the purchase order for.
4. Select a Category.
5. If the product is not listed, click Add New to create the product or service.
6. Enter the description and the amount.
7. Save the product.

To create a Purchase Order in Product and services, please follow these steps:

1. Click The Gear icon.
2. Under Lists, select Products and Services.
3. In the Products and Services page, find the product you want to associate with a Purchase Order. If the product isn’t listed, click New to add it.
4. Enter the product name, description, and other relevant details.
5. If applicable, set it as an inventory item, non-inventory item, or service.
6. Ensure you check the box labeled I purchase this product/service from a supplier. This ensures the product is available for use in a Purchase Order.
7. Save the product.
