I see the importance of being able to print the custom fields in the invoice or any other sales form, @Bo-Orlando. Let me share some information that can help you with this matter.
In QuickBooks, the ability to create custom fields is limited based on the subscription you purchase. Whether you have the Plus or Advanced subscription, printing invoices and purchase orders with custom fields is limited to a maximum of three.
As a workaround, you can add the necessary details in the message field so that it will show as you print your invoice or send it to your customer. Kindly follow these steps to add the information in your message fields:
- Go to the +New located at the top left corner of your screen.
- Under the Customers column, choose Invoice.
- Scroll down and go to Message on invoice.
- Enter the details that were supposed to be entered in Custom fields.
- Optional: You can click Print or Preview if you want to see how your invoice looks like when it is printed.
- Press Save and close.

Furthermore, you can also record your invoice payments if a certain customer paid an invoice.
