A delivery receipt your client can’t dispute
ImmutableProof records what you delivered and when, then locks the record so no one — including us — can change it.
Fast path
- Create a delivery record (free)
- Share a receipt link (client views without logging in)
- Export evidence only when you need it (credits)
What this proves
- Which files were delivered
- When the delivery record was created
- That the record has not been altered
ImmutableProof preserves facts. It does not provide legal advice or guarantee admissibility.
Pricing truth
ImmutableProof is free to use. You only pay when you export an evidence package. Verification remains free forever. Payment does not change proof semantics.
