hI I NEED URGENT HELP ON HOW TO UPLOAD INVOICE PAYMENT SINCE I DONT SEE ANY OPTION...

Dear Ibra Motel,

Welcome to the US Partner Community and thank you for reaching out to us.

You need to log in to your extranet account and go to the "Inbox" tab -> "Booking.com Messages" -> "Compose a new message". As a topic please select "Finance (invoices and payments)", then choose "compose new message" and you will see the option to attach a file there, at the end click on "send message". 

You can find more information about payment confirmations in this article.

Kind regards,

Toniya
