Inspection route app for fire protection companies

The idea

Fire extinguisher companies bill per unit inspected, and NFPA-10 requires documented monthly and annual service. The workflow today is paper hang-tags, clipboards, and an office person retyping results into Word certificates - slow, error-prone, and it routinely misses the real revenue: units quietly coming due for hydrostatic testing and 6-year maintenance, which are the high-margin services.

BuildingReports and similar incumbents are expensive and built around franchise networks. The wedge for the independent 2-10 tech company is a scanner-first app that makes the site visit faster, auto-surfaces due services as quote-able work, and emails a branded compliance certificate before the tech leaves the car park.

Who pays

The buyer is the owner of an independent fire protection company, at 69 USD/month per tech - covered many times over by one extra hydro test surfaced per week. Distribution: fire equipment distributor relationships, NAFED (the industry association), and direct outreach to independents whose certificates are visibly Word documents.

MVP scope

  • Site and extinguisher registers with barcode/QR identity per unit
  • Scan-to-checklist inspection flow with pass/fail and photo-on-fail
  • Automatic flagging of units due hydro test or 6-year maintenance
  • Offline-first capture with sync
  • Auto-emailed branded site compliance certificate PDF per visit
  • Skip for v1: route scheduling and dispatch, quoting/invoicing, other equipment types (alarms, sprinklers, hoods), customer portal

Build TagScan, a mobile app for fire extinguisher service companies doing
NFPA-10 inspections. Stack: React Native (Expo) with the camera-based
barcode scanner, Supabase for Postgres, auth, and storage, server-side PDF
generation for compliance certificates. Company account with tech
sub-accounts.

Setup (admin, web or tablet): customer sites, each with an extinguisher
register - per unit: asset barcode/QR, location description (e.g. kitchen
east wall), type (ABC, CO2, K), size, manufacture date, last hydro test
date, last 6-year maintenance date.

Tech flow on site: open the site, see the register with units not yet
inspected this visit. Scan a unit's barcode to open its checklist -
pressure gauge in range, pin and tamper seal intact, hose/nozzle clear,
signage visible, accessible, weight for CO2 units - each pass/fail, with a
photo required on any fail. The app computes due services from stored
dates: flag units due for hydrostatic test or 6-year maintenance so the
visit generates quote-able work, which is where these companies make their
money. Scanning an unknown barcode prompts add-new-unit on the spot.
Offline-first with sync - mechanical rooms have no signal.

Closing a visit generates a site compliance certificate PDF - company
branding, site, date, tech name, per-unit results, deficiencies and
recommended services - emailed to the site contact automatically; buildings
keep these for the fire marshal.

Screens: site list, register/scan view, unit checklist, visit summary,
history. Pricing: 69 USD/month per tech via Stripe, unlimited sites.
