It's nice to see you here in the Community, xenangel.

I can provide you with some answers to your questions about invoices.

In order to show the payments received on the invoice, you'll need to select the option Show on Invoice under Account summary in the template settings.

Here's how:

1. In the invoice screen, click Customize.
2. Select Edit current.
3. Go to the Content tab and click in the middle of the invoice to edit.
4. Under Account summary, select Show on invoice.
5. Hit Done.

I've attached screenshots below to guide you through the steps.

I've got your back if there's anything else I can help with. Have a nice day.
