If you win an item it will show up on your profile in the Won Items section under the Account drop-down. Auction houses typically email you an invoice with payment instructions within 24-48 hours of the end of the auction. Invoices will typically contain a blue “Pay Now” button that will direct you to a secure and simple checkout process on LiveAuctioneers.

If there's no "Pay Now" button, it means that the auctioneer is not using Live.Payments, and you need to either follow the instructions on the invoice or contact them to process the payment. 

Where is my invoice?

Sometimes email service providers will miscategorize messages as spam. Try checking your spam/junk folder for your invoice email. 

You can also check your Won Items page. Any open purchases that can be completed through LiveAuctioneers checkout are shown on your Won Items page.
