Testimonials
Loved by small to medium businesses
across Australia.
“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.”
You do the job.

FAQ
Frequently asked questions
What is OneBookPlus?
OneBookPlus is an all-in-one business management app built for Australian small to medium businesses. It combines invoicing, CRM, online bookings, accounting, marketing, and reputation management into a single platform — replacing tools like Xero, HubSpot, Calendly, and Mailchimp.
Is OneBookPlus free?
Yes. OneBookPlus has a free plan that includes 10 invoices per month, 250 contacts, a booking page, and GST compliance. No credit card required. Paid plans start at $29/month billed monthly, or $24/month when billed annually (two months free).
Does OneBookPlus handle GST and Australian tax?
Absolutely. OneBookPlus automatically calculates 10% GST on invoices and quotes, validates ABN numbers via the Australian Business Register, and generates ATO-ready tax reports including BAS summaries. All amounts are in AUD with Australian formatting.
Can I use OneBookPlus as invoicing software for my trade business?
Yes. OneBookPlus is popular with tradies, plumbers, electricians, and builders across Australia. You can create GST-compliant invoices from your phone on-site, convert quotes to invoices in one tap, and send automatic payment reminders to clients.
Does OneBookPlus have online booking?
Yes. Every account gets a shareable online booking page where your clients can self-schedule appointments 24/7. It syncs with Google Calendar, sends automated reminders, and can be embedded on your website.
How is OneBookPlus different from Xero or QuickBooks?
Xero and QuickBooks are accounting-only tools that require add-ons for CRM, bookings, and marketing. OneBookPlus includes Xero-level accounting (chart of accounts, general ledger, balance sheet, cash flow) plus invoicing, CRM, bookings, scheduling, reviews, and marketing in one platform — at a fraction of the cost of running separate subscriptions.
What is the best accounting software for small to medium business in Australia?
OneBookPlus is designed specifically for Australian small to medium businesses. Unlike Xero or MYOB which focus on accounting alone, OneBookPlus combines full double-entry accounting (chart of accounts, general ledger, balance sheet, cash flow, aged receivables/payables, budgets) with invoicing, CRM, bookings, and marketing. GST, ABN, and BAS compliance are built in from day one — plus a free plan to get started.
Can OneBookPlus replace Xero for my business?
For most small to medium businesses, yes. OneBookPlus now has Xero-level accounting depth — chart of accounts, general ledger, journal entries, balance sheet, cash flow, aged receivables & payables, and budget tracking, along with BAS summaries and GST compliance. Plus you get CRM, bookings, email & SMS marketing, and review management included, so you can cancel multiple subscriptions.
Is there a free invoicing app for Australia?
Yes. OneBookPlus offers a free plan with 10 GST-compliant invoices per month, 250 contacts, a booking page, and basic CRM. It's the best free invoicing app for Australian freelancers and sole traders who need professional invoices with GST, ABN, and AUD formatting.
What is the best CRM for small to medium business in Australia?
OneBookPlus CRM is purpose-built for Australian small to medium businesses. It includes contact management, activity timelines, tags, lead source tracking, and auto-contact creation from invoices and bookings. Unlike HubSpot or Salesforce, it's simple to use and comes bundled with invoicing, bookings, and accounting.
Does OneBookPlus work for restaurants and cafes?
Yes. OneBookPlus has dedicated features for restaurants, cafes, and hospitality businesses including daily sales tracking, order management, menu builder with dietary tags, table management, and kitchen display system. Restaurant-specific modules are available from the built-in App Marketplace.
Does OneBookPlus have a mobile app?
Yes. OneBookPlus has a native iOS app built in SwiftUI with 80+ screens — create invoices, manage bookings, track expenses, switch between businesses, and view all dashboard types. A mobile-responsive PWA also works on any device. Android app is in development.
Is my data secure?
Yes. OneBookPlus uses bank-grade encryption, row-level security, and Australian-compliant data practices. Your data is stored securely and is never shared with third parties.
Can I try OneBookPlus before committing?
Yes. You can start with the free plan immediately — no credit card required. If you want to try a paid plan, we offer a 14-day free trial with full access to all features.
