About OneBookPlus apps
OneBookPlus apps aren't external integrations stitched together with Zapier or n8n — they're native modules installed inside the same platform you already use for invoicing, bookings, CRM, and accounting. That means Tax Practice Suite reads from and writes to the same customer records, financial entries, and calendar events as every other module, with no scheduled sync delays and no risk of data drift between systems.
Because the marketplace runs inside OneBookPlus, billing is consolidated. Tax Practice Suite appears as a single line on the same OneBookPlus invoice as your plan, so you don't end up reconciling separate vendor charges across three or four different SaaS subscriptions. Cancellation is one click and never reaches into your data — uninstalling an app removes the feature from the UI but preserves the underlying customer, invoice, and booking records, so reinstalling later picks up exactly where you left off.
Every app in the marketplace is built specifically for the Australian small and medium business context: GST and ABN handling are first-class concerns, dates render as DD/MM/YYYY, currency defaults to AUD, and the underlying compliance plumbing (BAS summaries, ATO-friendly records, AHPRA / NDIS / Fair Work checkpoints where relevant) is shared across modules.

Common questions about Tax Practice Suite and the OneBookPlus app marketplace.
Registered tax agents and BAS agents running a practice. It turns OneBookPlus into practice-management software — client management, lodgement, portal and reporting — connected to the ATO via Standard Business Reporting (SBR) with your RAN and TPB registration.
$29/month base covers the platform plus unlimited BAS and TPAR lodgement. Income-tax returns — IITR, CTR, PTR, TTR and FBT — are $2 per accepted lodgement, with the first 5 each month free. So a small practice doing a handful of returns a month pays little beyond the base.
Yes — MFA is enforced for all users, every lodgement is written to a 7-year ATO audit log, and the suite tracks your PI insurance and TPB compliance. Client access is per-client and secured.
