Is there a 'payment report' which shows which invoices have been paid on that day that can be transferred to a CSV file?

Thanks for dropping by here in the Community, @melanie38. I'll help you run a report that shows what you need.

You can pull up an Invoice list report and then customize it to show paid invoices on a specific date. To begin, these are the steps:

1. Click Reports on the left-panel menu, and search Invoice List.
2. Click the Customise button, and set the Report period.
3. Go to the Filter section, and select Paid in the A/R Paid field.
4. Click Run report.

Once done, you can proceed to export them to Excel. Feel free to visit this article for the steps: Export data, reports, lists, and more from QuickBooks Online.

Additionally, I'll leave these articles to help you in the future:

• Add, customise, or remove logos on sales forms
• Import multiple invoices at once
