One system for the whole paper trail.

From the moment a document arrives to the moment a signed reply leaves, Nexus numbers it, routes it, tracks it and keeps the evidence. No email chains, no spreadsheet trackers.

Sheet 02New in 1.114

Draft. Approve. Sign. Issue.

Outgoing letters no longer leave the system to be printed, signed and scanned back in. Nexus composes them on your letterhead, routes them for approval, collects verified signatures and issues the numbered PDF.

Compose on your letterhead

Write the letter or reply in Nexus. References, recipients and enclosures are filled in from the thread.

Route for approval

Send the draft through an approval route. Reviewers can approve, edit or return it with a comment.

Sign with a verified identity

The signatory receives the request in My Actions and confirms with their passkey or two-step code.

Issue the numbered PDF

Nothing is issued unsigned. On issue, Nexus stamps the numbers, places the signature and files the letter in the register.
