Everything to run
your whole business.

The typical Australian small business runs four separate SaaS subscriptions to do what OneBookPlus does in one: an accounting tool (Xero ~$35/month), a booking tool (Calendly or Cliniko ~$15 to $59/month), a CRM (HubSpot Starter ~$50/month or Zoho ~$45/month), and an email marketing tool (Mailchimp ~$13 to $75/month depending on contact count). Combined that's $113 to $229/month before integration costs.

The hidden cost of that stack isn't the subscription total, it's the data flow problem. Each tool keeps a separate customer database. A booking made in Calendly doesn't create a customer in Xero; a paid invoice in Xero doesn't update the contact's status in HubSpot; an email sent in Mailchimp doesn't know whether the recipient is a paying customer or a churned lead. Manual sync via CSV exports, paid Zapier workflows, or duplicate data entry fills the gap, every one of which is a place where the data drifts.

OneBookPlus modules share the same database. A booking confirmed in the booking module is the same customer record the CRM uses, the same contact the marketing module emails, the same payer whose paid invoice the accounting module reconciles. The "How OneBookPlus apps fit" block on every app marketplace page explains the technical architecture: native modules in one database, not federated APIs across vendors.

The visible consequences for Australian small businesses are concrete. A "customers who haven't booked in 60 days" segment is one query, not a CSV export-import cycle. An invoice on a completed booking is automatic, not a copy-paste between tools. BAS-ready summaries draw from every revenue source the platform touches (invoicing, bookings, POS, recurring billing) without your bookkeeper rebuilding the picture each quarter.

That is why the modules share one database rather than one price. Invoicing, quotes, contacts and bookings are on the Free plan. A double-entry ledger with Profit and Loss, Balance Sheet, cash flow and BAS-ready GST summaries, from the Starter plan. Bank statements come in by CSV, OFX or QFX file, there are no live bank feeds, and the report library is narrower than Xero's. Email campaigns and online payments start there too, and Plus ($49/mo) and Growth ($69/mo) lift the limits and add the AI. What you do not pay is a separate subscription per module, and optional marketplace apps like AI Companion are added on top of any plan. See pricing for the per-tier limits, or compare against the stack you currently run.

Modules currently in the platform: Invoicing with native 10% GST and ABN-validated tax invoices, Booking with automatic email reminders, CRM with deduplicated contacts and lead status tracking, Quotes with one-click conversion to invoice, Finance with BAS-ready quarterly reports, Marketing with Spam Act 2003 unsubscribe handling, Restaurant with table and menu management (and a live Kitchen Display app), and Dashboard for cross-module reporting.
