Quoting app for plumbers in New South Wales
Fixtures, rough-in, hot water and drainage. Sumitt turns the walk-through into a clean plumbing quote your client accepts and pays on, from their phone.
The NSWdeposit cap, licence line, payment-claim rules, variation rules and rates below are read from Sumitt’s own tables when this page renders, not written for it.
The rules in New South Wales that Sumitt already knows
Every rule below is read, when this page renders, from the tables the quote builder, the variation composer, the extension-of-time notice and the payment-claim generator run on. Sumitt warns and never blocks, and the page moves the day a table does.
Deposit cap in New South Wales
NSW caps residential deposits at 10%.
Sumitt's default deposit is 10% of the total including GST. It warns you when a deposit goes over the line; it does not enforce it.
Home Building Act 1989 (NSW)
Licence line in New South Wales
Plumbing work is licensed at any job value in every state, so there is no threshold to cross. In New South Wales Sumitt nudges you to add your licence number when none is on file, so it prints on every quote and invoice.
Security of Payment claims in New South Wales
Sumitt turns an overdue invoice into a payment claim under the Building and Construction Industry Security of Payment Act 1999 (NSW). If the contract is silent, the client has 10 business days to give a payment schedule.
The claim carries the endorsement wording the Act requires.
A claim must be served within 12 months of the work it covers (or the longer period your contract allows), from the last day of the month the work was done in, one claim per month.
Homeowner jobs are covered in NSW for contracts signed from 1 March 2021, but only if you held the licence the work required and any home building insurance it needed. If not, the Act gives you no entitlement for that work.

Variations in New South Wales
In New South Wales the variation rules Sumitt shows are cited to Home Building Act 1989 (NSW).
The variation must be in writing and signed by both parties, the same standard the Act sets for the contract itself.
Describe the change and its price effect; attach it to the contract record.
In NSW, work under an unwritten variation is generally unenforceable against the homeowner. You can do the work and lawfully be refused payment for it.
A signature before the varied work starts is a statutory element there, not just good practice.
Sumitt structures the variation and collects the signature, a record you keep, not legal advice. Where your contract sets its own variation process, follow it too.

Extensions of time in New South Wales
In New South Wales the contract sets the extension-of-time window. Sumitt's notice defaults to 10 calendar days from the day the delay ended, shows the countdown, and asks you to check the contract's own figure.
A template you serve in your own name, not legal advice. Your contract's own extension-of-time clause governs the window and the grounds, so check it and keep a copy of everything.
Compliance certificate in New South Wales
In New South Wales a Notice of Work goes in before starting, and the Certificate of Compliance goes to Building Commission NSW or the local regulator at completion, with a copy to the owner. Sumitt keeps the record and the reminder. You lodge with the regulator.
A compliance certificate record with the test results and the deadline lives on the job. Sumitt prepares the record and never lodges it. Not legal advice.

National figures per unit, ex GST, derived from Sumitt’s 2026 rate cards priced over the benchmark scope shown under each job; the last column prices the same scope on the Sydney / NSW metro card. Cost is the benchmark cost of doing the work before any margin, and Floor, Healthy and Premium are the sell rates that land those margins. Not a survey of what anyone else charges, and nothing here reflects what any Sumitt user charges. How to read it, and the method, are on the index.
