Frequently asked questions
What do I install?
Software for your business. Your IT team prepares its installation, chooses which documents to track and sets who can view them.
What information can we retrieve?
Document versions, recorded changes and approvals. Their links help reconstruct the record known at a given date and retrieve the sources behind a decision.
Can an auditor verify a record?
You choose what to share. The auditor can check the integrity and origin of the signed record, then examine its documents and references as part of the audit.
How can we evaluate the software?
Start with a real record and a few questions: retrieve a version, trace an approval or check a shared record. These examples help prepare a demonstration suited to your needs.
