Currently, PayPal is Sketchfab’s only payment processor. PayPal has made it possible to purchase a Sketchfab membership via USD with a credit or debit card. You can see this option through the Sketchfab Plans page.
Likewise, we can sometimes make an exception for a Sketchfab membership plan via wire. The only requirement is that the purchase must be an annual plan commitment - Premium or higher. If you’re interested, message us.
