Supply-chain evidence crosses many organizational boundaries. Truthlocks connects a statement or reported handoff to its source so partners can compare records and investigate differences.

## Supplier networks: Check the declaration used in a purchase review

Buyers receive supplier documents through multiple channels and cannot easily compare versions.

### What to record

Record the declaration fingerprint, supplier identity reference, product scope, and the buyer’s recorded assessment.

### What to review

Check source and integrity, then evaluate the claim with the inspections or assurance evidence your purchasing process requires.

### The outcome

A traceable supplier statement connected to the decision it informed.

## Freight & forwarding: Keep a shipment’s document set consistent

Different partners may receive different packing lists or shipment instructions.

### What to record

Create a signed manifest of document fingerprints, shipment references, issuing source, and revision identifiers.

### What to review

Compare the documents at handoff with the manifest and resolve inconsistent details before the authorized next step.

### The outcome

A shared reference for the document versions associated with a shipment.

## Warehousing & distribution: Record a reported stock handoff

A disputed handoff may involve conflicting quantities across warehouse systems.

### What to record

Capture the transfer reference, declared quantities, responsible service or operator identity, and supporting evidence references.

### What to review

Compare the recorded handoff with inventory and physical-check evidence, then document the authorized resolution.

### The outcome

An action history that supports investigation of inventory differences.

## Before you begin

Agree on shared identifiers and issuing responsibilities with partners. Physical inspections and trusted source systems remain necessary to assess goods and delivery claims.
