WeTransfer is for Files. SecureViewPDF is for Business.
WeTransfer is a fantastic tool for sending big files. But for freelancers sending *intellectual property*, it has a fatal flaw: The Download Button.
The Moment You Lose Leverage
When you use WeTransfer, the client downloads your ZIP file. The transaction is done. If they don't pay you, you have no recourse because they already have the files.
Keep Control of the Asset
SecureViewPDF is not a file transfer service; it is a file viewing service. You are giving the client the privilege to view the work, not the ownership of the file.
This subtle psychological shift is huge for getting paid on time. They know that if they delay payment, the link might expire.
