Common questions
Do I need to pay anything?
No. The Tradie Portal is free for tradies. The builder pays for Build Margin; you get invited at no cost.
Do I have to use it?
Only if your builder asks you to. Some builders run their whole workflow through Build Margin; some just use it for variation approvals. Whatever works for the job.
What if I prefer SMS?
The Tradie Portal sends an SMS when you get a new task or a variation needs approval. You can do most things by replying to the SMS without opening the portal at all.
What about my existing invoicing?
Keep using it. Build Margin lets you upload the invoice you generate in Xero, MYOB, QuickBooks, or anywhere else as a PDF or photo. You don't change your existing workflow.
What about SOPA in other states?
SOPA payment claim nudges launched in Victoria first because that's where the legislation is most complex. NSW, QLD, and WA are coming through 2026.
Builder asked you to use Build Margin?
You don't need to do anything yet — they'll send you a magic link when there's a task.
