Sign-Level Reference Documents — Help Centre

Sometimes a specific sign needs its own supporting material — a mounting diagram, a wiring schematic, or a close-up reference photo. Sign-level reference documents let you attach files directly to an individual sign so contractors see them alongside the sign's details.

You have two ways to add a document to a sign:

Upload a new file dedicated to this sign.
Link an existing event-level document that you already uploaded to the event.

Linking is the right choice when the same document applies to many signs (a generic install guide, brand standards, an emergency contact sheet) — you upload it once at the event level, then link it to whichever signs need it. There is no extra storage cost for a linked document and any rename or category change at the source propagates everywhere automatically.

Adding a document

Open your event and go to the Signs tab.
Click the sign you want to add a document to.
On the sign detail page, scroll to the Reference Documents section.
Click Add.
In the dialog, choose a tab:
- Upload new — select an image or PDF from your computer.
- Link existing — pick one or more event-level documents from the list and click Link.

You can attach up to 5 reference documents per sign. Linked documents count toward this limit, since contractors see linked and uploaded documents as one combined list.

Linked vs uploaded documents

In the sign's document list, linked documents have a small Linked badge. They behave the same way as uploaded documents — contractors can open them, they're cached offline, and they appear in the sign's PDF export.

Two important differences for organisers:

Editing the name, description, or category of a linked document must be done from the Event Documents page. The change applies everywhere.
Removing a linked document from a sign uses the unlink icon — this only removes the link. The original document stays on the event documents page and on any other signs it is linked to.

Removing a document

For an uploaded document, click the Delete icon. The file is permanently deleted from the sign and from storage.
For a linked document, click the Unlink icon. The link is removed; the source document is unaffected.

There is no versioning on reference documents. To update a file, delete the old one and upload the replacement.

How contractors see sign-level documents

When a contractor opens a sign in the mobile app, every reference document attached to the sign — whether uploaded or linked — appears in the Reference Docs section. They're cached for offline access along with the rest of the sign data, so contractors can open them on site even without signal.

When to upload vs link

Upload a new file when the document is unique to this one sign — a one-off bracket detail, a custom artwork callout, a sign-specific photo reference.
Link from event documents when the document applies to many signs — a generic install guide, an emergency contact sheet, a brand colour standard, a site safety plan.

For documents that should be visible to every contractor regardless of which signs they're working on, leave them as event-level only — see event-level reference documents.
