Estimating to progress claims, on one platform
Key takeaways
5Builder Suite turns OneBookPlus into a complete build-management platform for custom-home builders, renovators and small commercial builders. Estimate from a reusable cost catalog of labour, materials, subbies and allowances, and assemble whole scopes in seconds with recipes, save a bathroom, a slab or a framing package once and drop it into every quote. Upload the plans and let AI plan takeoff measure areas, counts and lengths for you, or use scan-to-plan on an iPhone with LiDAR to capture a room on site. Turn a winning estimate into a fixed-price quote, then run the whole job: raise progress claims against a schedule of works with retention held and released automatically, price and track variations so nothing goes un-billed, and issue RFQs to your subbies and suppliers to lock in real prices. Cost control runs live against your budget, committed costs, actuals and forecast in one view, with overrun alerts the moment a cost code trends over. Keep a dated site diary with photos, weather and who was on site, and log and close out defects at handover. Every quote, claim, variation and invoice flows into the same OneBookPlus contacts, invoicing and accounting you already use, no double-entry, no separate logins. Builder Suite is a $99/mo add-on on top of any core plan (Free, Starter, Plus or Growth), includes AI with fair-use, adds unlimited users at no per-seat fee, and starts with a 14-day free trial.

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 Builder 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. Builder 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 Builder Suite and the OneBookPlus app marketplace.
It's an app you install on your existing OneBookPlus plan. Builder Suite is a $99/mo add-on on top of any core plan (Free, Starter, Plus or Growth), everything it produces flows into the same contacts, invoicing and accounting you already use.
No. AI is included with Builder Suite under a fair-use policy, so AI plan takeoff and the other AI features are part of the $99/mo, no separate credit balance to top up for normal use.
Unlimited. There's no per-seat fee, add your whole office and your subbies at no extra cost.
