The best online booking system for most Australian small businesses is OneBookPlus, an all-in-one, Australian-built platform that combines online bookings with GST invoicing, payments, automated reminders and a built-in CRM, on flat with a genuinely free plan. If you only need to schedule meetings, is the simplest; for beauty and wellness, is the category specialist; and has one of the most generous free tiers for small teams.
This guide ranks the leading options honestly, shows what to look for, and compares current Australian pricing so you can choose the right booking system for your situation.
OneBookPlus, best all-in-one for AU small businesses. Online booking plus GST invoicing, quotes, payments, reminders and CRM in one Australian app. Flat pricing (not per seat) and a $0 free plan. Best when you want bookings and the paperwork handled together.
Calendly, best for simple meeting scheduling. The cleanest way to let clients pick a time slot and sync it to your calendar. Best for consultants, coaches and B2B teams who don't need invoicing.
Acuity Scheduling, best for service businesses already on Squarespace. Mature appointment features (packages, intake forms, memberships) tied into the Squarespace ecosystem.
Fresha, best for salons, spas and wellness. Deeply specialised for beauty, with a marketplace that can bring in new clients. Note the marketplace new-client fee.
Square Appointments, best if you also run a Square POS. A free single-staff tier and tight integration with Square card payments and point of sale.
Setmore, best free tier for small teams. Free for up to four users and 200 appointments a month, with a low-cost Pro upgrade.

OneBookPlus is built for Australian service businesses that want one app instead of a stack of subscriptions. You get a professional online booking page with real-time availability, services, staff, buffers and deposits, and the moment a booking is taken it flows straight into the rest of your business.
What sets it apart for AU operators:
Truly all-in-one. Bookings, GST invoicing, quotes, jobs, CRM, accounting and an AI assistant in a single login. A completed booking can auto-generate an invoice and create or update the customer record, no re-keying into Xero or HubSpot.
Flat pricing, not per seat. Add staff without the bill climbing with every calendar, which is how Calendly, Setmore and Fresha's Team plan scale.
A real $0 free plan. Start accepting online bookings and sending invoices without a card.
GST, ABN and BAS-native. Invoices show GST and your ABN correctly, payments are in AUD, and your data lives in AWS Sydney.
Calendly is the benchmark for "pick a time" scheduling. Share a link, the booker chooses a slot, and it lands on your calendar with a video link attached. There's a capable free plan, with paid Standard from around USD $10 per seat per month (annual) and Teams from about USD $16 per seat per month.
Best for: consultants, coaches, recruiters and B2B teams booking calls and demos. Choose Calendly when you don't invoice through the same tool and just want frictionless meeting scheduling. Its limits show once you need GST invoicing, deposits, job tracking or a customer database, see the OneBookPlus vs Calendly comparison.
Now part of Squarespace, Acuity offers polished appointment features: service packages, intake forms, memberships, gift certificates and class scheduling. Pricing starts around USD $16/month for the Emerging plan (annual), rising to roughly USD $27 (Growing) and USD $49 (Powerhouse).
Best for: established service businesses, especially those already running a Squarespace website. Choose Acuity when you want depth in scheduling and don't mind billing and invoicing living in separate tools. It's USD-priced and not built around Australian GST workflows.
Fresha is purpose-built for salons, spas and clinics, with strong rostering, retail and a consumer marketplace that can surface your business to new clients. It dropped its free subscription tier, with Independent from A$44.95/month and Team from A$29.95/month per member. The marketplace charges a one-time 20% new-client fee (minimum around A$8); direct bookings via your own link, Instagram, Facebook and Google are commission-free.
Best for: beauty and wellness businesses that value the marketplace and salon-specific tooling. Choose Fresha when you're firmly in that vertical and want client discovery. Watch the marketplace new-client fees and card-processing rates, and note it isn't a general GST invoicing or job-management platform, compare it in OneBookPlus vs Fresha.
Square Appointments has a genuinely free tier for a single staff member and integrates tightly with Square's POS and card payments. Paid plans (Plus from around A$40/month per location, Premium around A$90) add multi-location, unlimited staff and class booking, with AU card fees of roughly 1.6% in-person and 2.2% online.
Best for: businesses already using Square hardware and POS, or shopfronts that take a lot of card payments. Choose Square when payments and a free single-staff calendar are your priority. It produces sales receipts rather than GST tax invoices, so it's a lighter fit for trades and B2B billing.
Setmore's free plan covers up to four users and 200 appointments a month, including a branded booking page, email reminders and payment acceptance. Pro adds SMS reminders, two-way sync and recurring appointments from about USD $5 per user per month (annual).
Best for: small teams who want a free, no-fuss calendar. Choose Setmore when scheduling is all you need and four users is enough. As you grow it bills per user, and like the others it doesn't handle GST invoicing or accounting, see OneBookPlus vs Setmore.
Solo and only need to book calls: Calendly's free plan or Setmore's free tier. If you also send invoices, start on the OneBookPlus free plan instead and keep it in one app.
Trades, mobile or home services: OneBookPlus, bookings, quotes, deposits, jobs and GST invoices in one place beat a scheduler plus separate accounting.
Salon, spa or clinic: Fresha if you want the beauty marketplace; OneBookPlus if you'd rather flat pricing, no marketplace fees and full invoicing/CRM.
Shopfront already on Square: Square Appointments for the integrated POS and free single-staff calendar.
Growing team that hates per-seat bills: OneBookPlus flat pricing avoids costs climbing with every staff calendar.
Already on Squarespace: Acuity slots neatly into that ecosystem.
For most Australian small businesses, OneBookPlus is the best online booking system because it combines online bookings with GST invoicing, payments, reminders and a CRM in one Australian-built app, on flat pricing with a free plan. If you only need to schedule meetings, Calendly is simpler; for beauty and wellness, Fresha is the specialist; and Setmore offers a strong free tier for small teams.
Yes. OneBookPlus has a $0 free plan, Setmore is free for up to four users and 200 appointments a month, and Square Appointments is free for a single staff member. Calendly also has a free tier for basic one-on-one scheduling. Fresha no longer offers a free subscription.
Most pure schedulers (Calendly, Acuity, Setmore) do not, they book the appointment but leave billing to a separate tool. OneBookPlus issues GST-compliant tax invoices with your ABN automatically when a booking is completed, which is why it suits Australian trades and service businesses.
Automated SMS and email reminders and optional deposits at booking are the two biggest levers; businesses commonly report meaningfully fewer no-shows once both are enabled. OneBookPlus includes reminders and Stripe-powered deposits on its booking pages.
If you want one Australian app for online bookings, invoicing, quotes, CRM and payments, on flat pricing with a free plan, start with OneBookPlus. Pick Calendly for pure meeting scheduling, Fresha for beauty, Square if you live in its POS, and Setmore for a free small-team calendar.
