Great question! To mark a sponsor invoice as paid, you’ll typically want to navigate to the sponsor deal, scroll down to the invoice section, and click the “Edit” button next to the invoice. From there, you should see a toggle option to mark the invoice as paid. If the invoice was paid directly through the invoice link, then the invoice will automatically be marked as paid. If you're not seeing this option on your end, it's likely a bug. Please feel free to reach out to us at support@eventeny.com so we can take a closer look and help resolve it. Let us know if you have any other questions!

That option does not seem to be available when I follow your notes. It was paid via check directly to us so it must be updated manually.
