Hi there,BHollis.
If you referring in creating an invoice and the non-inventory SKU you've created will not let you to select it, I suggest putting a checkmark under I sell this product/service to my customers from Product/Service information. This way, to make sure that the non-inventory you've made will show as chooses in the Product/Services column. To do this, you'll need to edit the non-inventory SKU you've setup.
Here's how:
1. Click the Gear icon and select Products and Services.
2. Select the non-inventory you've created and click the Edit option in the right corner.
3. Put a check mark in the I sell this product/service to my customers box under Description.
4. Click the Save and Close button.
Once done, you have already the option to select the Non-inventory you created and also you'll see the SKU option.
If you mean that it doesn't show up the SKU option when setting up non inventory from Product/Service information, I suggest to turn on this option from Account and Settings. Please follow the steps provided by my colleague above.
Please know that you're always welcome to post if you have any other concerns. Wishing you and your business continued success.
