This mostly comes down to trust,
Upfront payments are just a workaround for not having a system that guarantees both sides.
Surprised this isn’t the default yet 🤔
A simple rule I stand by:
I don’t start any project without upfront payment.
If you’re a growing designer or freelancer, don’t either.
50–70% upfront keeps things clear, protects your time, and holds both sides accountable.
