About the template

Avoid these
Common mistakes on aircon installers invoices
The patterns that quietly lose jobs, get queried at payment time, or leave money on the table.
Mistake: Certificate of Compliance reference missing
Better: Legally required. Always include the COC reference number on the invoice.
Mistake: Unit brand not named
Better: Daikin 5-year, Mitsubishi 5-year warranty differ. State brand and model on every line.
Mistake: Pipework length silent
Better: First 3m typically included, extra billed. State exact length installed.
Mistake: Electrical work bundled
Better: Dedicated circuit and isolator is separate trade work. Itemise so customer sees compliance.
Mistake: Warranty registration not confirmed
Better: Register the unit with the manufacturer on the customer's behalf. State on invoice.
Mistake: No banking reference
Better: Banking reference must be invoice number for same-day matching.
