About the author
Founder & CEO, OneBookPlus
Bishal has over a decade of experience in digital marketing, web development, and small business consulting across Australia. As a former freelancer himself, Bishal understands the challenges of managing invoicing, expenses, and tax compliance as a sole trader in Australia.
Most Australian freelancers start out with no proper system at all. You're writing invoices in a Word doc or Google Sheets, tracking expenses in a Notes app, guessing at GST when BAS time rolls around, and hoping you haven't missed a payment somewhere in your inbox. Eventually you cobble together Rounded for invoicing, HubSpot for CRM, Calendly for bookings, and maybe Wave for basic accounting — four tools that don't talk to each other and still leave you doing manual data entry at tax time. OneBookPlus replaces the entire stack with one free platform built for how Australian sole traders and freelancers actually work.
The platform covers the full freelance workflow from lead to lodgement. A potential client books a discovery call through your OneBookPlus booking page. You create a detailed quote with project phases, deliverables, and payment milestones — GST calculated automatically. The client accepts with one click and you convert it into a job. As you work, you track time against the project. When a milestone is hit, convert that phase to a GST-compliant invoice with one tap. The client pays online via the invoice link — card payments via Stripe land in your bank account within days. Automated reminders chase overdue invoices so you never have to send an awkward “just following up” email again.
Picture a typical Wednesday. You check your OneBookPlus dashboard over coffee — two invoices paid overnight totalling $2,800, one quote awaiting response, and a new booking request from your website. You accept the booking and create a three-phase quote: discovery at $600, first draft at $1,200, and final delivery at $900. GST is added automatically. You send it with one tap. Mid-morning, a client accepts a different quote. You convert phase one to an invoice instantly. At lunch, you log your Adobe Creative Cloud subscription and a co-working space day pass as business expenses — receipt photos attached. End of month: you open your profit and loss report. Revenue: $9,200. Expenses: $1,400. Profit: $7,800. Your GST summary is ready to send to your accountant or lodge yourself through the ATO portal.
Connect your business bank account and OneBookPlus pulls in transactions automatically. When a client pays an invoice via Stripe or bank transfer, the system matches the deposit to the invoice — no manual reconciliation. Business expenses like software subscriptions, equipment, co-working memberships, and travel are categorised and tracked against revenue so you can see exactly what you're taking home after costs. GST collected on invoices and GST paid on expenses are separated cleanly. At BAS time, export a one-click summary showing G1, 1A, G11, and 1B figures ready for lodgement. If you're not yet registered for GST (under the $75,000 threshold), simply toggle it off — invoices go out without GST and the system adapts.
Sign up in under a minute — no credit card, no trial period, genuinely free. Add your ABN, upload your logo, and set your bank details for payment. Import existing clients from a CSV or add them as you go. Most freelancers send their first invoice within five minutes of signing up. The free plan includes unlimited invoices, unlimited quotes, expense tracking, and up to five clients — more than enough to run a small freelance practice. When you grow beyond five clients or want bank feeds and advanced reporting, upgrade to a paid plan that still costs less than Rounded alone.

Real-world scenario
How a Sydney freelancer uses OneBookPlus to manage her design business
Priya checks her OneBookPlus dashboard over coffee — two invoices paid overnight ($3,200 total), one quote awaiting response, and a new booking request from her website.
She accepts the booking — a brand identity project. The client gets a confirmation email with her terms. Priya creates a quote with three phases: discovery ($800), concepts ($1,500), and final files ($700). GST is calculated automatically. She sends it with one tap.
Midmorning, she logs a Canva subscription and Adobe CC payment as business expenses — photos of receipts attached. At lunch, a client accepts her quote. She converts phase one to an invoice instantly.
End of month: Priya opens her P&L report. Revenue: $8,400. Expenses: $1,200. Profit: $7,200. GST collected and paid are separated clearly. Her BAS summary is ready to send to her accountant — or she can lodge it herself.
