The platform
Every part of the business, structured
No sprawl, no dependency on a dozen disconnected tools. Just the core of running a business, done right - and connected end to end.
Quotes → invoices
Sequentially numbered, PDF-ready documents with a clear status lifecycle - Draft, Sent, Issued, Paid. Convert a won quote into an invoice in one click.
Expenses & GST
Track vendor costs by category with GST support. Deductions flow straight into your tax view - so tax time is never a scramble.
Tax, BAS & deductions
Estimate income tax as you type, track your BAS quarters, and manage deductions across the financial year - GST collected, credits, and net payable.
Tasks & Kanban
Plan operational work per client or project, then track execution on one global board.
Timesheets
Log billable time against clients and tasks, and keep every billable hour in one place.

How to write a quote that wins work
Why speed beats polish, what belongs in a quote beyond the price, and how scope creep gets designed in or out before the job starts.
What must legally be on an Australian tax invoice
The exact fields the ATO requires on a tax invoice, the extra rule for sales from $1,000, and the details that get invoices paid faster.
How to get invoices paid on time
Late payment is a systems problem, not a personality problem. Payment terms that work, and a follow-up sequence you can run without dread.
