Yes! In this case, the Advance Card is an extra added bonus - enabling you to get the 30% up front just like you can with work from the Xometry Job Board today.
And with Xometry Pay, they can expand that up front 30% to all their jobs that they run through the Xometry Pay platform - not just ones from the Job Board.
All that said, the Advance Card and FastPay are optional, and definitely not a requirement for participating on the Xometry Pay platform.
