Fire Extinguisher Service Invoicing App (2026)
Fire extinguisher service is billed per unit inspected, per unit serviced, and per deficiency corrected — across a route of buildings on annual and monthly cycles. ShowTheReceipts ($15/mo) saves per-unit inspection and recharge rates, invoices a whole building's tag run in one pass, records the deficiency list as billable line items, and sets the next visit before you leave the site.
How we picked
Entry-plan prices as published in 2026, taken from each vendor's own pricing page or a recent third-party summary. Judged on the one-truck fire protection tech's workflow — per-unit billing, recurring annual cycles, deficiency line items, and invoicing on site — not on enterprise asset portfolios, multi-branch dispatch, or barcode inventory systems built for national accounts.

The route is the business
One extinguisher is a $20 line item; a building of thirty is a real invoice. Fire extinguisher service makes its money on density — buildings clustered on a route, all coming due in the same month, each with a tag date you set yourself a year ago.
Software that can’t hold a recurring cycle just makes you rebuild your own calendar every January.

The lines an extinguisher invoice needs
- Annual inspection — per unit
- Six-year maintenance — per unit
- Hydrostatic test — per unit, by cylinder type
- Recharge — per unit, by agent and size
- New unit sale and install — with bracket and signage
- Deficiencies corrected — itemized, each naming the unit
- Site minimum or trip charge
- After-hours or occupied-building surcharge
Price the deficiency list openly
Techs who find nothing get called back next year at the same price. Techs who report every deficiency in writing get the repair revenue and a customer who trusts the record — and the ones who fake either end of that don’t stay licensed for long.
The tag date is a renewal you already own
Every unit you service carries your name and a date twelve months out. That’s about as reliable as recurring revenue gets in the trades, provided something reminds you before the building’s insurer does.
Frequently asked questions
How should extinguisher service be billed?
Per unit, in tiers: annual inspection, six-year maintenance, hydrostatic test, and recharge each carry their own rate. Add a trip or minimum charge per site so a building with four extinguishers is still worth the drive.
Do I need software that scans barcodes?
Not to get paid. Barcode asset tracking matters when you're managing thousands of units across national accounts; a solo tech serving local buildings needs accurate per-unit billing, a recurring schedule, and an invoice that leaves with them.
How do I bill deficiencies found during an inspection?
As separate line items on the same invoice, each naming the unit and the finding. That list is both your repair revenue and your record that you reported the condition — never bury it in a lump 'service' line.
Can ShowTheReceipts handle annual recurring visits?
Yes. Set the cycle when you finish the job and the next visit is scheduled before you leave, which is how compliance work stays profitable — the renewal is the business, not the first sale.
