About the template
What this alarm installer invoice template covers and why it gets paid fast
Alarm invoices stall when totals are bundled. The template below shows the panel installed, sensors by zone and type, sirens, keypads, monitoring integration completed and each matching the quote line for line.
12-month warranty on parts and workmanship, plus the manufacturer's panel warranty (typically 24 months), are stated on the invoice for customer records.
What to include
Every alarm installers invoice should have these lines
Use it as a checklist when you build your invoice from scratch, or pull the QuoteGenio template that already has them.

Avoid these
Common mistakes on alarm installers invoices
The patterns that quietly lose jobs, get queried at payment time, or leave money on the table.
Mistake: Panel and sensor lines bundled
Better: Itemise each. Customer matches the invoice to the quote and pays without query.
Mistake: Warranty period missing
Better: State '12-month workmanship warranty' on the invoice. Required for future service claims.
Mistake: Sensor type per zone not stated
Better: Show each sensor type and location. Customer's reference for future service or upgrades.
Mistake: User code handover not documented
Better: List 'master user code handed to nominated user' on the invoice. Pre-empts 'we never got the code' disputes.
Mistake: Cellular SIM expiry not stated
Better: If the GSM module uses a SIM, state the contract expiry so the customer renews on time and signal isn't lost.
Mistake: Battery replacement schedule missing on invoice
Better: Reference the panel battery and sensor battery replacement intervals on the invoice for owner's records.
