Hi @seandm69,

Let’s edit the Master style of your invoice to populate the SKU numbers on the printed purchase order. Let me guide you on how to do it.

Here's how:

1. Go to the Gear icon.
2. Choose Custom Form Style
3. Edit the Master style of the invoice template.
4. Click the Contents tab.
5. Select the middle part of the Invoice.
6. Under COLUMNS, put a tick box on the SKU.
7. Hit Done.

Once done, you can go to the Products and Services page. Edit the items and enter the SKU number individually. In the line item of the Invoice, select the item and hit Save. Then, click the Print or Preview option to check the printed template with SKU number.

For a reference, you can check this link on how to modify your product or service information: Edit a product or service.
