Best Invoicing App for Plumbers in Australia (2026)
Quick Answer: For sole trader plumbers who want invoicing + job management + compliance in one app, TradeDesk ($59/year) offers the best value. For invoicing-only, Invoice2go or Xero are solid choices.
What Plumbers Need in an Invoicing App
Generic invoicing apps work for accountants and consultants. Plumbers need specific features:
- Mobile-first: You invoice from the van, not a desk
- GST handling: Automatic 10% calculation and "Tax Invoice" formatting
- Materials + labour split: Customers expect to see the breakdown
- Photo attachment: Before/after photos on the invoice build trust
- Quick send: Email or text the invoice in under 60 seconds
- Payment tracking: Know who's paid and who hasn't at a glance

Do You Need a Separate Invoicing App?
If you're already using Xero for accounting (which most plumbers' accountants recommend), you might think you should invoice through Xero too. But Xero is designed for accountants, not tradies in vans. Creating an invoice in Xero from your phone is painful.
The better approach: use a job management app (like TradeDesk) for creating and sending invoices on-site, then sync to Xero for accounting. You get speed in the field and accuracy in the books.
