Did you list your payment terms in the listing? This at least gives buyers an idea of a seller's anticipated payment date.
Meanwhile, you can't do anything for minimum 4 full days... after that, you can file the Unpaid Item Dispute:

Sellers may start the Unpaid Item process 4 days after auction close. They can close the Unpaid Item Case as early as 4 full days later, issuing a nonpayment strike to the buyer.
Sellers should not relist or make any Second Chance Offers, until the Case has closed.
