How OneBook Plus Invoicing works
Add your client
Search for an existing contact or create a new one. Client details auto-fill from your CRM — ABN, address, email, all there.
Add your line items
Type a service or select from your saved services catalogue. GST calculates instantly. Add a description, quantity, or discount per line.
Send in one click
Email the invoice directly from OneBookPlus. Your client receives a professional branded email with a PDF attachment and Pay Now button.
Get paid automatically
OneBookPlus tracks payment status. If it goes overdue, reminders fire automatically. When paid, the invoice closes and your accounts update.
Invoicing Software for Australian Small Business
Finding the right invoicing software in Australia means more than just sending bills. Australian businesses need GST-compliant invoices that meet ATO requirements, automatic 10% GST calculation on every line item, and ABN display on all tax documents. OneBook Plus Invoicing handles all of this automatically — no manual tax calculations, no compliance guesswork.
Unlike standalone invoicing tools like Rounded or FreshBooks, OneBook Plus connects your invoices directly to your CRM, bookings, quotes, and accounting. When a quote is accepted, it converts to an invoice in one click. When an invoice is paid, your revenue tracking updates instantly. There's no data re-entry between disconnected tools, and your BAS summary stays current in real-time.
For tradies invoicing from the job site, freelancers billing project milestones, or salon owners closing out appointments — OneBook Plus invoicing works on any device. Create a GST-compliant invoice in under 30 seconds, attach a Stripe payment link, and set automated reminders that chase overdue payments on your behalf. The free plan includes invoicing with no credit card required.

Real-world scenario
A day with OneBook Plus Invoicing
How a Melbourne consultant uses invoicing on a typical Friday
Rachel finishes a strategy workshop at 11am and creates an invoice on her phone before leaving the client's office — $2,200 plus GST, pre-filled from the accepted quote. The client gets a professional PDF with a Pay Now button.
After lunch, she checks her dashboard: two invoices paid overnight ($4,800 total), one going overdue tomorrow. She doesn't chase it — the automated reminder fires at 9am.
End of week: $8,600 invoiced, $6,200 collected. Her GST summary shows $563 collected this month. Come BAS time, she exports the summary in one click and sends it to her accountant. Total time on invoicing admin this week: 12 minutes.
