OneBookPlus - 2026 Pricing, Features, Reviews & Alternatives

OneBookPlus is an all-in-one business management platform built in Melbourne for Australian small and medium-sized businesses. It brings invoicing, quotes, CRM, online bookings, double-entry accounting, and email and SMS marketing into a single system, replacing the separate subscriptions that owner-operators usually pay for and connect by hand. Invoicing produces ABN-compliant tax invoices with 10% GST applied automatically, online payment links through Stripe, recurring billing, and automatic reminders, while the built-in accounting covers chart of accounts, general ledger, balance sheet, cash flow, profit and loss, and ATO-ready BAS summaries.

The CRM keeps a full timeline of every client's invoices, quotes, bookings, payments, and notes, and the online booking page syncs with Google Calendar so a confirmed booking flows straight into an invoice without re-entering details. An AI Companion automates the repetitive admin, chasing overdue payments, following up no-shows and quotes, and harvesting reviews.

OneBookPlus suits service-based businesses such as trades and home services, health and wellness, beauty, fitness, professional services, and accounting practices that have outgrown spreadsheets and disconnected apps but do not have dedicated IT or marketing staff. Data is hosted in Australia on AWS in the Sydney region, encrypted in transit and at rest, and isolated per business at the database level.

A native iOS app is available for iPhone and iPad, and the web app installs on Android and works offline, so the whole platform runs from a job site or a desk. A free plan is available with no credit card required.
