That's quite an idea to make your sales transactions readable, @Jason4. I'll share a way to ensure you've got spaces between product items on your invoices.

When adding certain items to your invoices, we can enter them alternatively to provide spaces in between. This way, it will be easy to read for your customer especially when you have to enter a long description for your items. To do that, you can follow the steps below:

1. Click the Customers menu and select Create Invoices.
2. Choose a customer from the Customer:Job dropdown to whom you creating this transaction.
3. In the product item section, select what product or services you have rendered to your client.
4. Then, leave one space or row before adding another product item.
5. Enter additional transaction details you may have, and click Save & Close or Save & New.

After that, you can also review how it looks by previewing the transaction. Here's how:

1. Open the invoice you recently created, and click the dropdown arrow under Print.
2. From there, select the Preview option and see how your items are placed.

Furthermore, you can check out this article to see how you can record an invoice payment once your client pays their statement of charges: Record an invoice payment.
