OneBookPlus vs Buildxact
The all-in-one Buildxact alternative for Australian builders

Yes, for residential builders and trade contractors who want estimating, plan takeoff, progress claims and cost control without paying $399/month for Buildxact Pro or bolting on Xero for accounting and a separate gateway for payments. Buildxact is genuinely strong on estimating heritage and live supplier price files. OneBookPlus matches the estimate-to-claim workflow and adds online payments, native GST accounting and a full-featured mobile app for a flat $99/month for the whole business, with no per-seat charge (the core plan bands logins at one on Free, three on Starter, five on Plus and ten on Growth). If plans-first takeoff with live merchant pricing is your entire workflow, Buildxact's specialism may still suit you; for most builders who also need to get paid and keep their books straight, OneBookPlus is the more complete and cheaper path.

As published on buildxact.com/au/pricing and verified as at August 2026, Buildxact runs three flat tiers with unlimited users (ex GST): Foundation $199/month, Pro $399/month, and Master $599/month. Foundation is a pre-construction and sales tool, it does not include invoicing, job management, the mobile app or accounting sync, so the tier most builders land on is Pro at $399/month, plus a separate Xero, MYOB or QuickBooks subscription for accounting and Blu AI add-ons ($99 to $149/month) for AI estimating. Buildxact's pricing rewards larger teams (users are unlimited) but is expensive for smaller ones who still land on the $399 Pro tier. OneBookPlus's Builder Suite is $99/month for the whole business with no per-seat charge, and it includes estimating, takeoff, claims, cost control, payments and native accounting on top of a core app that starts free. The core plan bands logins rather than seats: one on Free, three on Starter, five on Plus and ten on Growth. Check buildxact.com/au/pricing for its current figures before you decide.

Yes. OneBookPlus does AI-measured takeoff on PDF and photo plans with zoom and pan, drag-to-correct directly on the plan, and ‘pick one, find all’ symbol counting that Buildxact still does by hand. One honest caveat: the AI measures into a review queue you check and correct before the numbers reach a quote, rather than pricing a plan on its own. It also goes the other way on a reno with no drawings: scan the room on an iPhone with LiDAR and the measurements come straight into the estimate, which Buildxact does not offer. Buildxact is the more mature 2D plan tracer with years of refinement; OneBookPlus adds AI counting and a streaming estimate generator on top of the same core workflow.

No. Buildxact has no payment collection anywhere, its client-portal invoices are view-only, with no card or BECS option. That means the money still lands in a separate system. OneBookPlus takes card and BECS payments directly on progress claims and invoices, so the payment settles in the same app that raised the claim. It is one of the clearest practical gaps between the two products for a builder who wants the money to arrive against the claim rather than in a separate gateway.

Yes. Buildxact has no native accounting, BAS, P&L and GST reporting all run through a Xero, MYOB or QuickBooks integration, and accounting-sync problems are one of Buildxact's most recurring complaint classes. OneBookPlus includes a GST-native ledger and BAS-ready reporting in the same subscription, so a builder can retire both the estimating tool and the separate accounting bill and stop reconciling across two systems. OneBookPlus also handles GST-inclusive entry and display, which Buildxact's tax-exclusive-only engine does not.

With Buildxact, cancelling means you lose access to your past quotes and jobs unless you keep paying a monthly fee to retain read-only or hibernated access to your own data. OneBookPlus keeps data export free at any time on every plan, your estimates, claims and job records are yours to take with you whenever you like, with no lock-out and no ransom. If keeping ownership of your history matters, that difference is worth weighing before you commit.

Your cost catalogue and recipes are the part that moves cleanly: export them from Buildxact to CSV and import them into the OneBookPlus cost catalogue, then check your labour rates, wastage percentages and markup defaults before you price anything with them. Contacts import the same way. Here is the honest limit: completed Buildxact quotes and jobs do not import as live OneBookPlus records, so most builders finish the jobs already running in Buildxact there and start new estimates in OneBookPlus from a chosen cutover date, usually the start of a quarter so the BAS boundary is clean. Keep a Buildxact export for your own records while you still have access, because that access ends when the subscription does.

The free core plan gives you contacts, quoting and invoicing with 10 invoices and 5 quotes a month and 250 contacts, which is enough to test the feel of the app but not enough to run a build. Plan takeoff, the estimate generator, progress claims with retention, variations, cost control and RFQs all sit in the Builder Suite app at $99/month on top of whatever core plan you are on, including the free one, with a 14-day trial and no per-seat charge; the core plan bands logins at one on Free, three on Starter, five on Plus and ten on Growth. So the realistic comparison for a builder is $99/month against Buildxact Pro at $399/month plus a separate accounting subscription, not $0 against $399, and we would rather you did that sum than be surprised by it.
