OneBookPlus made quoting and invoicing so much easier for our roofing jobs. We used to waste hours on paperwork — now everything is done from the phone on-site. The GST compliance alone saves us a headache every BAS quarter.

Running a restaurant means juggling a million things at once. OneBookPlus handles our bookings, invoices, and daily sales tracking in one place. We finally stopped paying for four different apps.

80+ native screens. Built in SwiftUI for speed, with everything syncing to the web in real time.
Create and send ATO-compliant tax invoices from the job — 10% GST and your ABN applied automatically.
View, confirm, and reschedule appointments; your online booking page syncs in real time.
Photograph an expense and the AI extracts the supplier, date, GST, and total for you.
Every client's invoices, bookings, jobs and notes in one timeline — no second app.
Know the moment an invoice is paid or a new booking lands, wherever you are.
Biometric unlock; data hosted in Australia and isolated per business at the database level.
Your subscription and data are shared across both — start an invoice on your phone, finish the books on your laptop. Everything syncs in real time.
iOS app
The fast jobs you do between appointments — quote and invoice on-site, confirm a booking, snap a receipt, check who's paid, take a payment. Built for iPhone and iPad with Face ID and push alerts.
Web app — full platform
For the deeper work, sign in at my.onebookplus.com.au: full double-entry accounting and BAS, bulk invoicing and reconciliation, payroll and rostering, the App Marketplace, reports, and every setting. It also installs to your Android home screen and works offline — so non-iPhone users get the complete platform too.
Yes — the app is free to download on the App Store and works on the free OneBookPlus plan (10 invoices a month, a booking page, GST compliance, no credit card). Paid plans unlock unlimited invoices and more, and your subscription works across the app and the web.
The app is a native iOS app built in SwiftUI and runs on iPhone and iPad. Download it from the App Store and sign in with your existing OneBookPlus account, or create one in about 90 seconds.
A native Android app is in development. In the meantime, the OneBookPlus web app works on any Android device at my.onebookplus.com.au — it installs to your home screen and works offline like a native app.
The iOS app covers the day-to-day jobs you do on the move — invoicing, quotes, bookings, jobs, contacts, expenses, payments and dashboards across 80+ screens. Heavier admin (bulk accounting, settings) is best on the web app; everything syncs instantly between them.
Yes — it's built for exactly that workflow: quote at the kerbside, convert to a GST invoice in one tap when the job's done, take payment, and snap material receipts before they're lost. Plumbers, electricians, builders and other trades use it as a single app for jobs, invoicing and bookings instead of juggling separate tools.
In Australia. OneBookPlus hosts data on Australian infrastructure (AWS Sydney region), encrypts it in transit and at rest, and isolates every business at the database level. Signing in on the app and the web uses the same account and the same data.
OneBookPlus is an all-in-one business management app built in Melbourne for Australian small and medium businesses, and the native iOS app is now live on the App Store for iPhone and iPad. It puts the jobs you usually do at a desk — GST invoicing and quotes, online bookings, a full CRM, double-entry accounting, and an AI Companion that chases payments and follows up leads — into one app you can run from a job site, a salon chair, or the front seat of the van. It's free to download and works on the free plan, with no credit card required.
Unlike overseas apps that treat Australian tax as an afterthought, OneBookPlus applies the 10% GST and your ABN to every invoice automatically, validates ABNs against the Australian Business Register, and produces ATO-ready BAS summaries. That matters: an invoice without a valid ABN can trigger 47% withholding, and GST has to be right on every line. The app and the full feature set are Australian-first by design, priced in AUD.
The app is used across more than 40 industries — it's a job and invoicing app for tradies, plumbers and electricians; a booking and payments app for salons, clinics and personal trainers; and a point-of-sale and accounting app for cafes and retail. Create a quote on the kerbside, convert it to a GST invoice in one tap, take a card payment, and let the AI Companion request the review — without touching a second tool. You can compare it to the stack most operators stitch together on our Xero comparison and across the features overview.
Your OneBookPlus account is one subscription across both surfaces. The iOS app is tuned for speed and the move; the web app is the complete platform, with the deepest accounting, bulk invoicing and reconciliation, payroll and rostering, the App Marketplace, and every report and setting. Everything syncs in real time, so what you do on your phone is on your laptop by the time you're back at the desk. On Android, the web app installs to your home screen and works offline, so non-iPhone users get the full platform today while the native Android app is in development.
Download the app, sign in or create an account in about 90 seconds, and you're on the free plan — 10 invoices a month, a booking page and GST compliance, no credit card. Paid plans unlock unlimited invoices and more, and your data is hosted in Australia and isolated per business at the database level (see how we protect your data). Not sure where to start?
