Document control software that keeps the register current and the record complete.
For the document controller who owns the register. Number every drawing and technical document to your convention, keep revisions under control, route approvals, issue transmittals, and hold a full audit trail behind every change.

A spreadsheet register cannot hold the documents it lists.
Most document control still runs on a register in Excel, next to a folder of PDFs. The spreadsheet did the job for years, and it still lists every drawing and number. What it cannot do is hold the file the row points to, prove which revision is current, mark the superseded copy, or show who approved a change, and when.
Lunr is document control software where the register and the documents are one thing. Every controlled document carries its number, its revision history, its approvals, and its audit trail on the same record.
Read what makes a document controlled- 01The register lists a document number, but the file it points to lives somewhere else, and the two fall out of step.
- 02Which revision is current is whatever the last person typed into the row.
- 03A superseded drawing stays in the same folder as the live one, with nothing to mark it.
- 04Approvals happen over email, so the register cannot show who signed a document off, or when.
- 05There is no record of which transmittal sent a document out, or who received it.
One register, with the documents inside it.
Book a document in and Lunr numbers it to your convention, reads the title block into metadata, and files it in the register. The number, the discipline, the sheet size, and the title come off the drawing, so a controller does not retype what is already printed on the sheet.
- Automatic numbering applies your register format, prefix, and sequence as documents are booked in.
- Title-block tags are read into metadata, so drawing number, revision, discipline, and sheet size come off the sheet.
- Every document type sits in the one register: DWG, DGN, RVT, PDF, IFC, Word, and Excel.
- Filter and sort the register by project, discipline, status, or revision to find a document fast.

The current revision is never in doubt.
Lunr keeps the full revision history on every controlled document and marks the previous revision as superseded the moment a new one is booked in. The live document is the one the register serves, the superseded copy is kept and labelled, and no one issues an out-of-date sheet by mistake.
- A full revision history on every document, so any change can be traced back years later.
- The superseded revision is kept and marked, never deleted and never mistaken for the live one.
- Overlay two revisions to see exactly what moved, or read them side by side.
- Revision numbering follows your scheme, letter or numeric, applied as each revision comes in.

Route a document through review and approval, on the record.
Move each controlled document through the review and approval workflow you configure. Assign reviewers, hold a document until it is signed off, and stamp the approved revision as the one the register serves. The status on the record is the real status, not a colour in a spreadsheet cell.
- Configure review and approval workflows to match how your team signs a document off.
- Assign reviewers and approvers, and hold a document at each stage until it is cleared.
- The approved revision is the one the register serves, marked and dated on the record.
- Raise a change request against a controlled document, and track it until it closes.

A transmittal records who received what, and when.
Issue a transmittal and Lunr keeps the record of it: which documents went out, at which revision, to whom, and on what date. When someone asks whether a contractor had the current drawing, the answer is on the transmittal, not in a sent-items folder.
- Issue a transmittal covering a set of documents at their current revision.
- The transmittal records the recipient, the date issued, and the revision of each document sent.
- Every transmittal stays on the record, so who received what is a lookup, not a reconstruction.
- Reissue when a revision changes, and the register shows who is holding an old copy.

The audit trail writes itself behind every change.
Every controlled document carries a full audit trail: each workflow transition, each revision, each approval, and each tag edit, logged with the person and the time. When a regulator or an auditor asks who changed a document, and when, the evidence is on the record, ready to export.
- A full audit trail on every controlled document, logged with the person, the action, and the time.
- Workflow transitions, approvals, revisions, and tag edits all record on the one timeline.
- Filter the trail to the events an audit cares about, and export the evidence.
- Handover and submittal packages validate against a manifest, so a missing document is caught on upload.

One controlled record, connected to the systems you run.
Lunr holds the document record while your other systems keep doing their jobs. Read and write CAD through the connector APIs, tie documents to place in Esri GIS, and connect the facilities systems that run the estate. Every capability is included as standard, with pricing shaped to your organisation.
Read and write DWG and DGN through the connector APIs, so authored files and the controlled record stay in step.
Tie each document to its place on the network, and open the controlled record from the map.
Connect Archibus, MazeMap, and SISfm, so the systems that run the estate share the document record.
Bring documents in from OneDrive, and sign staff in through your identity provider over SAML.
See every CAD, GIS, and facilities connector on the connectors page.

Questions document controllers ask.
What the software does, how the register works day to day, and what it takes to move off a spreadsheet.
- What does document control software do?
- Document control software keeps your controlled documents in one register, with a clear current revision, superseded copies kept and marked, approvals routed and recorded, and a full audit trail behind every change. Lunr does this for engineering documents: drawings, technical reports, and asset records in DWG, DGN, RVT, PDF, Word, and Excel. It replaces a spreadsheet register and a folder of files with one record where the number, the revision, and the file are the same thing.
- What is the document controller's workflow in Lunr?
- Book a document in and Lunr numbers it to your convention and reads its title block into metadata. Route it through review and approval, and the approved revision becomes the one the register serves. Issue a transmittal to send it out, and the recipient and date are recorded. When a revision changes, the previous one is marked superseded, and the audit trail records who changed what, and when. The controller works from the register, not from a folder tree.
- Can Lunr apply our document numbering convention?
- Yes. Automatic numbering applies your register format, prefix, and sequence as documents are booked in, so numbers follow your convention without being typed by hand. Lunr also reads the drawing number, revision, discipline, and sheet size from the title block into metadata, so the register fills itself from what is already printed on the sheet.
- What audit and compliance evidence does Lunr keep?
- Every controlled document carries a full audit trail. Each workflow transition, approval, revision, and tag edit is logged with the person and the time, on one timeline you can filter and export. Handover and submittal packages validate against a manifest, so a missing document is caught on upload. When an auditor asks who approved a document, or which revision was issued, the evidence is on the record.
- How does Lunr handle superseded documents?
- When a new revision is booked in, Lunr marks the previous revision as superseded and keeps it on the record. The live document is the one the register serves, and the superseded copy is labelled so no one issues it by mistake. Nothing is deleted, so the full history stays available, and you can overlay two revisions to see exactly what changed.
- Does Lunr keep transmittal records?
- Yes. Issue a transmittal covering a set of documents at their current revision, and Lunr records the recipient, the date issued, and the revision of each document sent. The transmittal stays on the record, so who received what, and when, is a lookup rather than a search through sent email. When a revision changes, reissue, and the register shows who is holding an old copy.
- Can we move our register off Excel and shared drives?
- Yes, and it is the usual starting point. Import documents in bulk, and Lunr reads title-block tags into metadata, so the register fills itself rather than being retyped. Automatic numbering applies your format as records come in, and your existing numbers are preserved. Export all documents and metadata at any time, so the record stays yours. The University of Canberra moved more than 20,000 documents off SharePoint into a controlled register on Lunr.
