Hello there, @judie-driscoll-g.
You can use the Message on statement box on the Invoice page. It shows the information in the Memo column from your customer's invoice lists. Here's how:
1. If you're about to create an invoice, go to the +New button.
2. Select Invoice under Customer.
3. Enter the needed information.
4. In the Message on statement box, enter the details you want to generate in the Memo column.
5. Once ready, click Save.

Then, let's go back to your customer's list of invoices to view and double-check the memo field. Here's how:
1. Go to Sales on the left panel and select the Customers tab.
2. Click the name of the customer you created an invoice with.
3. Make sure to include the Memo field. If not, click the Gear icon and tick the Memo box.
