Client says they never received the files

This is one of the most common freelance disputes. Without an independent record, it becomes your word versus theirs.

Why this happens

• Email attachments get “missed”
• Download links expire
• Platforms lose history
• Memories change under pressure

ImmutableProof creates a cryptographic delivery receipt. Once created, no one — including us — can change it.
