Builder Not Paying Invoice NSW
Practical guidance for getting paid, understanding SOPA, and keeping your claim moving.
If a builder has stopped replying, delayed payment, or keeps asking for more paperwork before paying your invoice, you are not stuck waiting forever. In NSW, the Building and Construction Industry Security of Payment Act gives many subcontractors, tradies, and suppliers a faster way to claim payment for construction work and related goods or services.
What SopaServe does
SopaServe helps NSW trades and suppliers turn unpaid invoices into compliant SOPA payment claims. You upload your invoice and key job details, and we help create a payment claim process that is easier to send, track, and follow up. The goal is simple: make it harder for unpaid work to be ignored.
Builder not paying your invoice in NSW?
Late payment is common in construction, but it can quickly create serious cash-flow pressure. You may have paid for labour, materials, hire equipment, subcontractors, or delivery costs before the builder pays you. If the work relates to construction in NSW, SOPA may give you a formal pathway to claim what is owed.
What is SOPA?
SOPA stands for the Security of Payment Act. It is designed to help people in the construction industry get paid faster by setting out a formal payment claim process, response deadlines, and a path to adjudication if payment is still disputed or ignored.
What you can do next
Check whether the unpaid invoice relates to construction work, materials, equipment, or services supplied in NSW.
Collect the invoice, contract, quote, emails, site details, and any evidence that the work was completed or supplied.
Prepare a compliant payment claim. A normal invoice may not always be enough if it does not include the right information.
Serve the claim properly and keep a record of when and how it was sent.
Track the response deadline and consider next steps if the builder does not issue a payment schedule or still refuses to pay.
How SopaServe helps
SopaServe is built to reduce the admin around unpaid construction invoices. Instead of guessing what to send, you can create a clearer SOPA-ready claim workflow, keep everything in one place, and move faster when a builder is delaying payment.
