🔧 Your Equipment History, Crowdsourced: Guest QR Logging via Transfer Inbox

The paper work order tucked inside the unit panel is the standard. The tech does the work, writes it up, folds it, and leaves it in the panel or mails it to the office. Weeks later, nobody has updated the maintenance log. The service history has a gap that only closes when someone finds the paper, deciphers the handwriting, and enters it manually.

Any technician who scans the Link Mode QR code (available for Pro subscribers) on a piece of equipment can now submit a full service record through their phone browser — no Equipment Tracker account, no app install, no friction on their end. The submission lands in your **Transfer Inbox** the moment they tap Submit. Note: Creating and displaying Link Mode QR codes is a Pro-tier feature, but once generated, guest submissions are completely free for visiting technicians to submit.

How It Works for the Guest Tech

When a guest technician scans the Link Mode QR tag on a unit, they land on the public specification page — the same read-only page they have always been able to see. The difference now is a "Log Service / Repair" button at the top of the maintenance history section.

Tapping it opens a full service submission form right in their phone browser. They fill out the service date, pick the type of work (Preventive Maintenance, Repair, Inspection, Installation, Emergency, or Other), enter their name and company, describe what was done, list any parts replaced, and optionally attach a before photo and an after photo from their camera roll.

Hit submit. Done. The whole thing takes about two minutes, and it requires nothing from them beyond a phone with a camera.

Your Records Stay Clean — Nothing Merges Without Your Approval

Guest submissions do not touch your equipment records automatically. They arrive in your **Transfer Inbox** as pending items — you see the technician name, company, service type, description, parts used, and any before/after photos attached. Accept imports the submission directly into the equipment maintenance history, photos included. Decline permanently deletes it and removes the photos from storage.

This is the security mechanism that makes the feature usable. A public QR tag on a piece of equipment is scannable by anyone who walks past it. The Transfer Inbox ensures that only submissions you explicitly review and approve ever become part of your permanent equipment history. Your data stays clean regardless of who scans the tag.

Before and after photos are stored in encrypted Firebase cloud storage until you act on the submission. If you accept, they transfer permanently to the equipment record. If you decline, they are deleted entirely.

Why We Built It This Way

The design goal was to remove every possible obstacle for the person submitting the service. If they have to download an app, they probably will not do it. If they have to create an account, forget it. The QR code is already on the unit. The form opens in their browser. That is the entire workflow from their side.

At the same time, the account holder stays in control. Nothing gets added to your database without your review. You either accept it as submitted or decline and delete it. The guest never touches your actual equipment records directly.

The Vendor Field Is Now Separate on All Records

As part of this update, we also separated the technician name from the contracting company across all maintenance records — not just guest submissions. Previously both landed in a single "Technician" field, which made records like "John Smith / Apex Mechanical LLC" harder to filter and report on.

Now there are two distinct fields: Technician Name and Company/Vendor. Both show up independently on service lists, in generated PDF reports, and in the maintenance history view. The vendor field is included in all exports, imports, peer-to-peer pushes, backups, and cloud syncs — so your records stay properly attributed no matter how the data moves.
