OneBookPlus is an Australian-owned, all-in-one business management platform built in Melbourne for small and medium businesses across more than 40 industries — from trades and cleaning to healthcare, fitness, retail and professional services. It replaces fragmented stacks like Xero + ServiceM8 + HubSpot + Calendly + Mailchimp with a single AU-hosted product that handles invoicing, online bookings, CRM, marketing, point-of-sale and Australian compliance (GST, ABN and BAS) natively. A generous free plan lets sole traders start without a credit card, while paid tiers unlock advanced automation, multi-team workflows and industry-specific apps from a built-in marketplace. By keeping data on Australian infrastructure and pricing in AUD, OneBookPlus removes the friction of stitching together overseas SaaS — giving operators one system, one bill, and one source of truth for the whole business.
