Plumbers & plumbing contractors
Bill Format for Plumbers
A plumbing job is often urgent and often cash — which is exactly when a bill is easiest to skip. But a customer who paid for a leak repair without a record has no way to call you back if it leaks again next week, and neither do you.
What this bill must include
- Your business name and a phone number the customer can call back for a follow-up leak or blockage
- The customer's full address — plumbing work is site-specific, so the property matters as much as the customer's name
- The date and, for an emergency or after-hours call-out, the time you attended
- Each fitting or repair on its own line — say cistern replacement or drain-blockage clearing, not a single plumbing work entry
- Fittings and pipe or sealant materials priced separately from your labour or call-out charge
- Whether the job is a repair or a full new installation, since customers often ask for this distinction later for warranty or resale purposes
- GST, if you're registered
- The total due, the payment method, and any callback window you're covering if the same issue recurs

On tax
List materials (fittings, pipe, sealant) separately from your labour charge — it makes a repeat callout easy to compare against the last one, for you and for the customer.
Common mistakes
- No written record for an emergency or after-hours job, when a bill is easiest to skip entirely
- Bundling materials and labour into one number, so neither of you can tell what changed next time
- Verbally quoting one price and billing another, with nothing in writing to settle the difference
- No visit or call-out charge listed separately, so it looks like it was free when it wasn’t
